Through the network, people can stay at home to complete the campus idle items, which is convenient for students at the same time to solve the traditional campus idle items management state, because there is no standardized campus idle items management system, all the tedious work must be completed by manual. The management of idle items on campus is very complicated, generally including the collection of the number of idle items on campus, the count of the number of idle items on campus, and the increase, deletion, and modification of the number of idle items on campus. This kind of pure artificial management method really has many shortcomings, such as: in the number of time to find the efficiency is very low, in order to check when easy to produce mistakes...... For this reason, the idle items on campus need to be constantly reviewed, resulting in a waste of human resources and economic foundation. This system selects wechat small program as the development environment, MySQL as the background data storage, so as to develop and design the function of data increase, modify, delete and query. Our business personnel can see the page related information of the front desk of the whole system through the browser, and then complete the corresponding interaction logic with the background server through a click event, so as to carry out a series of online campus idle items viewing steps.

1. Introduction
The development of computer networks has greatly improved the efficiency of schools and students. The development of any industry cannot do without the technical support of information technology. At present, in order to promote the healthy development of campus idle items trading and strengthen the management of idle item trading platform, this trading platform makes the order of busy schools more orderly, not only more efficient in the management of idle item information, but also enables students to obtain more Good trading experience [1]. Entering the new century, the arrival of the information age and the rapid development of science and technology have promoted the exchange of interconnected information on a global scale. With the continuous improvement of social and economic development and the deepening of information exchange, it is necessary to deal with a large amount of information on campus idle items. Secondly, an advanced and professional information management trading platform must be established to achieve management goals. A good information management trading platform can process information in a timely and effective manner, making information management even better in the era of big data. Therefore, the establishment of an idle goods trading website is not only the requirement of the development of the times, but also the need of school management.
Since the early 1980s, the research work of my country's idle items information website has a history of many years. It has gone through the single-machine single-request stage, the multi-machine demand stage, and the computer network integration stage. I have to admit that the idle item information management trading platform has made great progress during this period. At the same time, the massive demand for information from idle items has always been the driving force for the development of HIS. The key factors that promote the widespread use of computer information trading platforms for idle items in China are: idle items should strengthen their own management, gradually complete the price and transaction of idle items according to cost, and reflect the establishment and optimization of a reasonable internal distribution system for idle items [2]. Based on the above factors, there is an urgent need to establish an idle item information management trading platform centered on financial management.
(1) Research background of the topic
At present, it is very convenient and quick to obtain the information you want by consulting, browsing and reviewing idle goods transactions through the Internet. These requirements must be strengthened as soon as possible in terms of the current information construction of idle goods transactions. Through in-depth and detailed research on the current domestic and foreign campus idle goods transaction management trading platform, the existing problems were found, and the programming software was used to realize the number of idle goods transaction management trading platform based on the discovered problems, and the developed transaction The results of the platform are very suitable for the current needs, and the response is very good. It also introduces the characteristics of the idle goods trading management trading platform in detail, and at the same time combines some common problems existing in the construction process of the current idle goods trading management digitization, and conducts an in-depth and detailed analysis of the reasons for the existing problems. The countermeasures with strong operability are put forward, which provides a certain reference value for the current digital construction of idle goods transaction management [3]. It is hoped that it can promote the improvement of the digitization level of idle item transaction management. Then, digitization technology is used to realize the idle goods transaction management information platform based on the Internet.
(2) Research significance of the topic
Today, with the rapid development of the world economy, the particularity of numbers is more and more reflected, and it is gradually gaining the attention of the public. So how to develop and utilize multiple resources more effectively is a common concern of all countries. As we all know, campus idle item transactions generally have the ability to store a large amount of data, store the number of complex idle item transactions, different types of items, and so on. In the environment where users demand more and more functions, it needs the function of storing a lot of data. The idle goods trading management trading platform developed this time has realized the effective management of data. The result of this optimization makes it easier for students and users to manage and view various data about idle item transactions in the idle item trading hall, making the digital management of idle item transactions more purposeful. Although the idle item trading management trading platform has great advantages, its popularity is far from enough. In the idle goods trading hall that has not yet used the idle goods trading management trading platform, manual processing is still used at present, and the quantity of various data is manually marked [4]. Such a management method currently has many disadvantages. Especially when the data is too large, it is easy to cause statistical error information, and the management is inconvenient. The large amount of data is easy to cause loss, and it is difficult to consult later. Its disadvantages become more apparent when the amount of data continues to increase. Especially in the transaction of idle items with a large number and a large amount of data, how to realize fast search, how to quickly modify and manage has become a difficult point. In terms of dealing with this problem, the idle item transaction management trading platform has shown great advantages, such as being able to quickly check the required quantity, and it is convenient for the administrator to manage the quantity, the data storage is also relatively large, and it is relatively safe. High, and long storage time. At present, with the continuous development of technology, the management and trading platform of the idle goods trading hall needs to be constantly updated to adapt to the development and needs of the times. Only by putting forward higher requirements can we design a better digital idle goods trading platform. Therefore, I suggest that it is necessary to design a trading platform for the management and trading of idle items to make the management of the number of idle items more efficient and platform-based, and to meet specific requirements [5].
