- introduction
- research background and meaning
With the construction of campus networks in various schools and the introduction of Internet technology, system development based on campus networks and the Internet is also booming. The student information management system is an important part of teaching in each school. Modern student information requires the support of a modern information management system. Since the 1990s, in order to adapt to the goal of talent training in the new century, the domestic higher education system has undergone large-scale reforms.
Research Background:
With the rapid development of computer technology and the advent of the Internet age, we have entered the information age, which some people also call the digital age. In this digital era, the information management work of various universities has been greatly challenged in all aspects. With the continuous development and expansion of the education scale of various colleges and universities, the number of students has increased dramatically, and the amount of various information about students has also doubled. It also brings about an important issue in the development process of education in various colleges and universities, which is the management of student information. Facing the huge amount of information, it is necessary to have a student information management system to improve the efficiency of the student information management system, achieve standardized management of information, scientific statistics and rapid query, so as to reduce the workload of query work.
In recent years, more and more users have realized the importance of managing information and have begun to choose information management systems that suit them. The student information management system system is designed and developed based on these factors.

- Research status at home and abroad
Foreign research trends:
With the continuous development of foreign economies, the expansion of the scale of colleges and universities, the number of students has doubled, and the model of student information management systems has also undergone changes. With the continuous development of computer science and technology, information management systems have been used in various fields. play an increasingly important role.
Compared with domestic teaching and research software, foreign teaching and research software was developed earlier and is relatively mature. As early as the late 1970s, the United States established NSFNET (National Science Foundation Network), and its project applications and project progress reports were all conducted online. Its online student course selection system is also very complete. Students from all over the world can sit at home and complete the entire learning and life process of enrollment, course selection, examinations, graduation thesis, and obtaining a degree through the Internet. At present, there are hundreds of well-established distance education schools in the world. Online education is playing a huge role in various places, cultivating a large number of talents for countries around the world. All these show that the application of Internet-based campus network has penetrated into every aspect of the campus.
Domestic research trends:
With the development of higher education in our country, under the background of informatization and digitization, domestic universities urgently need to improve the quality and efficiency of educational work. Digital campuses will become an inevitable trend and gradually mature.
The student information management system is an important part of the information management work of colleges and universities. Many colleges and universities have developed student information management systems according to the scale and characteristics of their own schools, which separates managers from complicated tasks. Freed from daily routine work, improved work efficiency and realized information sharing. Some domestic universities and software companies are also optimistic about this software development with broad market prospects. However, there are still many problems in the existing student information management systems of universities, mainly:
1. Single function. A system is developed only to solve a specific problem. There is no close and effective connection between various related systems, which affects the reuse and sharing of information.
2. The system is isolated. Many systems are still in a stand-alone application state, that is, they are only used by managers responsible for this business. They do not realize the close connection between vertical and horizontal management work, and the interactivity is poor, resulting in repeated collection of information and repeated statistics. At the same time, the isolation between systems will result in incomplete searches when querying information and cannot provide sufficient information.
3. When it comes to the use of software, most of them only stay at the perspective of daily office work and lack comprehensive analysis capabilities. In addition, the student information management system also has poor scalability and flexibility, lacks strong follow-up technical support, and cannot continuously improve the system to adapt to the development needs of the school. As a result, these software have been abandoned or shelved after running for a period of time, causing a lot of problems. of waste.
Therefore, the developed student information management system uses computer-assisted course selection, which can conduct real-time inspection and statistics on a large amount of course selection data, and output the course selection results very conveniently, while also avoiding manual processing time. prone to errors.

- research content
At the beginning, this article gives an overall description of the basic knowledge discussed in the system, and conducts a system analysis on this basis. In order to enable this system to be designed and implemented in a better and more complete manner, analysis and investigation must be conducted first. Based on the previous related foundations, a detailed analysis of the new system was carried out in terms of functionality. Then through detailed analysis, system design was carried out. Secondly, in terms of the feasibility of system implementation, I chose the Thinkphp framework for development and design. For data storage, I used the Mysql database for design. Since both PHP and Mysql are very mature, they are very reliable, safe and practical in all aspects. Finally, the system is tested, perfected and released.
B/S architecture (browser/server) is currently the most widely used architecture, which can make system development, operation, and maintenance easy. You can use this structure when you have a database installed on your computer and a few very common browsers. The B/S structure can be directly used in the B/S system, and the B/S structure can greatly reduce the operation and maintenance of the system in practical applications. On the B/S platform, each database is independent of each other and has high security. Because the B/S architecture can clearly observe the business handled by the system, managers can make timely decisions, thereby avoiding corporate losses. The essential feature of the B/S architecture is centralized management. Users store the data generated by the system into the database to facilitate future applications, thereby meeting various needs.
The B/S model consists of three levels: a browser, a network server, and a database server. Data management adopts the presentation layer, application layer and data layer of most existing B/S systems. The Web browser is designed to meet user requirements and is an intermediate application layer used in data processing and logic processes, thus Form a distributed operating mode. The logic of the B/S architecture is that the processing completed on the front end leaves the main business logic to the backend, while the front end is only responsible for a small number of requests, rendering, etc. Due to the rapid development of Internet technology, the B/S architecture makes the system accessible at any time and anywhere.

- ThinkPHP framework
ThinkPHP was born to simplify enterprise-level application development and agile WEB application development. It was first born in early 2006, and was officially renamed ThinkPHP on New Year's Day 2007, and was released under the Apache2open source agreement. ThinkPHP has been adhering to the simple and practical design principle since its birth. While maintaining excellent performance and minimal code, it also focuses on ease of use. And it has many original functions and features. With the active participation of the community team, it is continuously optimized and improved in terms of ease of use, scalability and performance. [1]
ThinkPHP is a fast, compatible and simple lightweight domesticPHP development framework, which was born in early 2006, formerly known as FCS, in 2007 On New Year's Day, it was officially renamed ThinkPHP. It was released under the Apache2 open source protocol. It was transplanted from the Struts structure and made improvements and improvements. It also learned from many excellent foreign frameworks and models, usingobject-orientedObject-oriented a>’s development structure and MVC mode, integrating the ideas of Struts and TagLib ( tags library), RoR's ORMmapping and ActiveRecord mode.
ThinkPHP can support server environments such as windows/Unix/Linux. The official version requires PHPA variety of databases and PDO extensions. The ThinkPHP framework itself has no special module requirements. The specific application system operating environment requirements depend on the development involved. module. Sqlite, PgSQL, MySqlSupported by version 5.0 or above, supports
As an overall development solution, ThinkPHP can solve most needs in application development because it includes the underlying architecture, compatibility processing, and base classes< a i=2>Library, database access layer, template engine, caching mechanism, plug-in mechanisms, role authentication, form processing and other commonly used components, and are more convenient for cross-version, cross-platform and cross-database transplantation. And each component is carefully designed and perfected, and the application development process only needs to focus on your business logic.

- MySQL database
As a storage place for data, a database is a must for the project. MySQL is a very excellent relational database. The early MySQL was not owned by Oracle, but was acquired by him later. MySQL is very small, the installation package is only a few megabytes, and it is relatively easy to learn SQL language writing. The most important thing is that MySQL is also an open source software, so there is no need to pay extra. The system itself is also based on learning and summarizing the knowledge learned. Mainly, it is best to use free software as much as possible in system development, so MySQL is chosen for database management. The capacity of MySQL is also very large. It also supports the operation of sub-databases and tables, and supports distribution. Therefore, more and more small and medium-sized enterprises choose this database management tool. It is also worth mentioning that open source also has a disadvantage, that is, it is easy to be cracked and hacked, so MySQL is still used more in small and medium-sized projects.
MySQL does not require a platform, so any programmer can complete his own system development through the MySQL database and save a lot of resources. Because of its powerful features, it can be used to store data of this system.
MySQL is suitable for various applications. When we run the database, it is easy to get started. We only need to write a piece of code to complete the corresponding functions and can be used on any platform without the need for a second time. Compile. The MySQL database also has the advantages of storing data locally and allowing structured queries for easy management; MySQL is a completely networked system, and its database can be accessed from anywhere on the Internet, and it can be shared with anyone anywhere; In addition, MySQL also provides access control capabilities, which can prevent data from being used illegally. The MySQL service is stable and the development cost is low, so during the development process, the MySQL database is the most popular.
Feasibility analysis is also to analyze whether the project's development system is valuable for development, and whether it is really necessary to improve the management system's shortcomings in information dictation. Taking the design goals and implementation process of the student information management system of this project as an example, if this system is developed, it is hoped that it can well solve the user's management information problems, and if this enables the student information management system to develop the maximum value theory, and also It can solve users' problems to a certain extent in disguised form, so the research and development system of this project is the most valuable and meaningful system. But have the R&D goals achieved the desired results, and whether the scientific research tasks have the greatest utility and value after they are realized, and whether they are equal to all total costs. Therefore, the R&D stage is essentially the stage where the R&D system can be truly designed.
Technical feasibility means that the identified science and technology or the science and technology in decision-making methods do not break through the boundaries of the scientific and technological resources mastered by the organization or familiar to relevant personnel. In the process of technology research, attention should be paid to comprehensively investigating various key technical issues included in the system development process, selecting mature technologies as much as possible, carefully citing advanced technologies, paying attention to specific research platforms and developers, and evaluating the effectiveness of key technologies.
PHP technology is key to the design and implementation of this student information management system. Based on B/S architecture and MySQL database management, it is crucial for front-end applications and back-end database management. In order to effectively apply this program, It is necessary to maintain the characteristics of comprehensive functions, easy to understand and simple to use. When building database management, it is necessary to ensure that the data analysis information is complete, the data analysis information is stable, and the data analysis information is highly stable. In the early days, people had understanding and familiarity with the basic important knowledge points of PHP. They had a brief grasp and familiarity with the MySQL database. In the early days, they had a general grasp and practice of basic courses such as software engineering testing and UML language. After By practicing the above courses, you will be able to develop, test and judge the corresponding information systems for the above courses.
PHP can be combined with MySQL to develop a student information management system, which must be reasonable and effective.
The feasibility of implementing the national economy mainly includes two aspects: first, the potential possibility of obtaining and utilizing various resources of the national economy from a certain plan to be implemented; second, the potential possibility of achieving the overall goal of the national economic development policy; second, the potential possibility of achieving the overall goal of the national economic development policy; It refers to the economic costs and benefits obtained in order to complete a certain national economic development policy implementation plan. Since the government's financial resources are limited, each financial resource obtained and utilized from the national economic development policy implementation plan is also limited. Therefore, every public policy measure faces a competition for public financial capital. But in general, "the amount of social and economic resources occupied by public policy measures is directly proportional to the expected value of its policy measure goals." "Of course, this also touches on a cost-efficiency question. If the total cost of a certain method is equal to the profit, it is obvious that this socioeconomic policy measure is ineffective.
The original intention of developing this project was to save money. I did it by myself and basically did not need start-up capital. In addition, the entire process of project development is a self-study process, which is a win-win result. Therefore, in summary, the R&D advantages of this project outweigh the disadvantages, which is in line with the actual development of my country's current socialist market economy.
The registration and login page of the student information management system is designed to be simple and easy to use. You can log in to the page through the most common page window, and use a computer to implement the login function. Therefore, users can log in as long as they usually use a computer. The R&D work environment of this operating system uses PHP technology and a B/S structure. These R&D work environments make the system functions more complete, the entire design more personalized, and the user functions more concise and convenient. This management system has the advantages of easy operation, easy management, good interactivity, and is also very simple in actual operation. Therefore, this management system can also be designed commercially.
To sum up, the research and development of this equipment meets the technical, process and technical requirements, so its research and development is operable.

First, friendly interface. In the development and design of student information management system, the friendliness of the interface is more important. Only by meeting this requirement can it reflect the humanized design characteristics and adapt to the convenience of user application system. The dynamic human-computer interaction design allows users to feel when using the system. Convenience of operation and improved user experience can help fully bring out the value of system mining design.
Second, stability requirements. The student information management system developed and designed needs to maintain its stability. Only when the system application is stable can it help to complete various management tasks efficiently and improve the system usage experience. The system operation guarantees that the system crashes due to external anomalies. After the system has a problem, the data can be backed up in time, and the data information can be restored as soon as possible to ensure the good operation of the system.
Third, scalability. The development and design of the student information management system needs to meet scalability requirements. The system design needs to consider future system business expansion issues. With continuous application of tests, functional requirements will continue to expand. Through good scalability, it can meet diverse needs. need.
Fourth, meet needs. In order to effectively strengthen the demand for large users, in the process of developing the student information management system, it must be closely connected with the needs of practical applications to ensure the practicality of the system. System development must be forward-looking. Since management system construction is a long-term project, different stages need to be guided by a leading development blueprint and action plan. Consider the important issues of textbook ordering information management proactively. The development of the system must be able to meet the needs of flexible applications and fully bring out the value of the system.
The student information management system mainly serves student information management, using the network to change the traditional student information management model, simplifying the student information management system management process, reducing the workload caused by traditional student information management and reducing the consumption of a large amount of resources. The main goals achieved by this system are as follows:
(1) Through simple page design and convenient function operations, the simplicity and practicality of the system are ensured, and a good user experience is formed.
(2) This system is mainly designed and developed to meet the needs of student information management systems, highlighting strong pertinence.
(3) It can have certain security mechanisms to ensure the security of user information.
A hierarchical block diagram is a series of trees consisting of multi-layered rectangular frames, with a rectangular frame at the top representing the entire data structure, rectangular cubes below representing individual data, and rectangles below representing the actual data for that data (which cannot be divided). Due to the refinement of this architecture, the data structure described by the hierarchical block diagram has become more detailed. This model satisfies the requirements of demand analysis well. The top-level information is classified first, and then optimization is performed iteratively on each path in the graph until the complete data structure is determined.
This system consists of two modules, one is the administrator and the other is the ordinary user. These two parts appear to be independent, but in fact they are connected to the database. Each module has its own permissions. The only difference is that The way of access is different. Based on the research data, the functions of each module were completed. Based on the analysis of the above functions, this system proposes two main modules, each unit can be divided into several small units.
The functional structure diagram of the system is shown in the figure below.
Figure 4-2 System functional structure diagram
1. Login module:
User login in this student information management system involves the judgment of three types of information: the first type is whether the user name and password are empty; the second type is whether the verification code is entered and correct; the third type is user login information, verification code and permissions Whether the match is passed. In the user login process, it will be judged whether the user name and password are empty, and whether the verification code is correct. If there is a problem with only one of the above types of information, the login will not be successful.
2. Announcement management module:
The announcement management in this student information management system uses three basic operations on information: one is to complete the addition of announcement information, where the input of announcement information will be judged; the other is to complete the entry of announcement information; Modification, the other is to delete the announcement information. The next two operations are completed based on the announcement list generated by the first operation.

- 系统实现
- 登录模块的实现
用户登录的验证将不再局限于登录信息和权限的匹配验证，而是另外增加了一个验证码，只有界面上所有的编辑框数据都准确的情况下才能实现登录成功。管理员的登录和前台用户登录是一样的过程，其主要就是利用权限字段来完成对用户或管理员的角色识别。
用户登录流程图如下所示。
图5-1 用户登录流程图
登录界面如下图所示。
图5-1 登录界面
登录系统主要代码如下。
public function login()
{
if (Request::isPost()) {
$request = Request::param();
$result = $this->validate($request, $this->validate);
if (true !== $result) {
// 验证失败 输出错误信息
$data['error'] = 30000;
$data['message'] = $result;
} else {
$request['password'] = md5($request['password']);
$result = $this->model->login($request, $this->table);
$data = $result;
}
} else {
$data['error'] = 30000;
$data['message'] = "field的值不能为空！";
}
return json_encode($data);
}
public function login($request=[],$table_name = ''){
$username = $request['username'];
$password = $request['password'];
$bol = $this->where(['username'=>$username])->find();
if ($bol){
$password = md5($password);
if ($request['password']==$bol['password']) {
//添加token信息
$access_token['create_time'] = date('Y-m-d H:i:s');
$access_token['update_time'] = date('Y-m-d H:i:s');
$access_token['info'] = json_encode($bol);
// $access_token['info'] = $bol;
$access_token['token'] = md5(date('Y-m-d H:i:s'));
$bol_token = Db::name('AccessToken')->insert($access_token);
if ($bol_token){
$data['obj'] = $bol;
$data['obj']['token'] = $access_token['token'];
return ['result' => $data];
}else{
return ['error' => ['code' => 5000, 'message' => '登录失败,token生成失败']];
}
} else {
return ['error' => ['code' => 5000, 'message' => '登录失败,密码不正确']];
}
}else{
return ['error' => ['code' => 5000, 'message' => '登录失败,账号不存在']];
}
}
当访客点击学生信息管理系统中导航栏上的“校园资讯”后将会进入到该“校园资讯”列表的界面，然后选择想要看的校园资讯信息，点击进入到详细界面，在详细界面可以收藏+赞+评论等操作，校园资讯界面如下图所示。

- 修改密码模块的实现
-
用户使用该学生信息管理系统注册完成后，用户对登录密码有修改需求时，系统也可以提供用户修改密码权限。系统中所有的操作者能够变更自己的密码信息，执行该功能首先必须要登入系统，然后选择密码变更选项以后在给定的文本框中填写初始密码和新密码来完成修改密码的操作。在填写的时候，假如两次密码填写存在差异，那么此次密码变更操作失败，下面的图片展示的就是该板块对应的工作面。
密码修改流程图如下所示。

- 课程信息详情模块的实现
-
用户可以查看课程信息，在查询到自己想要了解的课程的时候，可以进入查看详细的介绍，点击“选课”这一按钮以后会跳转到选课信息填写的界面，根据提示填写好选课的信息，在课程信息详情这个界面，同时支持用户对喜欢的课程进行评论的功能。
课程信息详情界面如下图所示。
图5-1 课程信息详情界面
用户通过注册了方可获得登录使用权限，此时选择注册用户选项，系统就会自动转到用户注册工作面，在注册该部分信息时系统会自动调用add函数，然后在给定的文本框中填写有关该用户的基础信息后选择确认即可完成注册。检索用户信息，在新增用户信息以后，在检索工具栏中填写对应的用户信息，系统就会将该用户有关的所有信息展示出来。
用户管理流程图如下所示。
图5-1 用户管理流程图
用户管理界面如下图所示。
图5-1 用户管理界面
系统用户管理代码如下。
public function get_list($request=[],$table_name = '',$table_id = ''){
$page = 1;
$size = $table_name == "auth" ? 100 : 10;
$where = [];
$order = $table_id.'_id desc';
$field = '*';
// echo $order;exit;
$columns = Db::query( "show COLUMNS FROM `".$table_name."`");
foreach($columns as $key=>$val){
$field_name = $val['Field'];
if(isset($request['like'])){
if ($request['like']==true){
//字段模糊查询
if(isset($request[$field_name])){
$where[] = [$field_name, '=', $request[$field_name]];
}
}else{
//字段模糊查询
if(isset($request[$field_name])){

}
}
}else{

if(isset($request[$field_name])){
$where[] = [$field_name, 'like', '%' . $request[$field_name] . '%'];
}
}
//范围查询
if(isset($request[$field_name.'_min'])){

在这个产品被投入使用前，首先需要进行试用，这是重要的环节。考虑到某个部分的开发没有缺陷情况下，把各种模块拼接，也有一定概率就存在矛盾。这就好比每个人都很独特，但聚在一起就显得杂乱无章，需要保证有默契的配合。对于测试，要看它的各项内容是否契合的原则。若与最初定下的标准有一定程度上的出入，那么就需要做出一些调整，让最终的大方向朝着目标前进。
测试是为了发现在开发的程序中所存在的问题，测试这一工作是非常艰巨的，而又是非常困难的，这一部分在程序的设计中占有很大比例，可以说一个程序的开发工作量要是占据了百分至六十，那么剩下的百分之四十必然是测试这一部分，甚至更高。

结 论
本次学生信息管理系统利用了Web应用同现实学生信息管理系统管理工作进行相结合，在系统功能开始编码之前，作者花费了大量时间在图书馆内进行资料文献的收集和总结，通过大量文献的分析，能够发现，学生信息管理系统管理的方式在用户中扮演的位置是越来越重要，而使用的方式也是越来越多元化，也正是因为这个原因，作者深深的希望能够开发出一种专门针对学生信息管理系统，以满足用户的需求。
在本次学生信息管理系统中，利用了目前市场上普遍使用的PHP技术，以及数据库管理功能MySQL，和目前比较流行的ThinkPHP框架，最后配合使用到了VUE页面布局技术进行系统界面的布置，以现实生活的学生信息管理系统过程为标准，设计实现了校园资讯、公告查询、资讯浏览、课程信息查询、点赞收藏等功能，并维护好后台的信息和整体系统的稳定性。
但是由于作者受到了技术水平的限制，在有限的时间，只能够将系统功能模拟时的功能实现，在许多功能方面仍然存在很大的弊端，而这些弊端需要不断的测试，不断的总结，不断的改进。例如本次系统设计中，在数据储存的方面并不够全面，很容易出现信息泄露的风险；例如针对用户权限的设置同样不够全面完整，没有考虑权限在实际情况的运用是否能够完美执行。而在这之后的日子里，作者将会继续学习PHP技术和相关的信息技术，对系统功能进行更加完整的，详细的分析，将系统功能一一进行完善，帮助使用者完成相应的操作。

Thanks
On the occasion of the completion of this thesis, I would like to thank my supervisor. In the web design class of the instructor, I learned a lot, which also laid a certain foundation for my internship. The instructor also made many suggestions for my design and gave me careful guidance. They patiently guided me to improve the problem, gave me the experience of writing thesis, and often encouraged me. In addition, I would like to thank the front-end classmates who taught me to improve this project. For this project, I completed it while learning, and there are many things to start with. I don’t understand it very well, but my front-end development classmates very patiently guided me to complete this project. In the back-end development of the system, the back-end development technology used was often explained to me, which helped me better write the paper. Completed, I would like to express my heartfelt thanks to the classmates who helped me and the instructors who have always taught me, and wish me a successful career.
