First, configure the access to the CGI directory
1, install httpd
This is certainly not to say, CGI is providing web-based services, you definitely have to install a web service program.
Pick httpd, the terminal performs sudo yum install httpdthe installation.
2, find the cgi-bin directory and write a small program
Installed httpdlater in /var/www/the directory will be a cgi-bindirectory, this is the default cgiplacement program directory, can be used directly.
In this directory can be written directly to a CGI program, and then try to access.
For chestnut:
#! /usr/bin/env python
# -*- coding:UTF-8 -*-
print('Content-Type: text/html; charset=utf-8\n')
import os
print("你好")
print("<br>你的IP是：%s"%os.environ['REMOTE_ADDR'])
print ("<br>你的UA是：%s"%os.environ['HTTP_USER_AGENT'])
print("<br>你的请求端口是：%s"%os.environ['REMOTE_PORT'])
print("<br>你的请求路径是：http://anti-fraud.wiki%s"%os.environ['REQUEST_URI'])
print("<br>你的请求方法是：%s"%os.environ['REQUEST_METHOD'])
Explain:
1, the first line to declare the CGI program interpreter, here is the python, of course, also be used python3. However, when the output of Chinese python3 might be some problems, we discuss how to solve this later. Of course, you can also write path #! /usr/bin/python
2, the second line is to specify the encoding, note that after the second line of this code may be interpreted as a comment rather than coding.
3, the third line in response to print header information, a carriage return at the end is the end of the head.
4, several lines below the output of a number of environmental variables, such as the visitor's IP, UA and other information.
Access effect is as follows:
Second, add / change the CGI program path
1, the path change CGI
Although the program is up and running. However, the cgi-binpath to change to change how I do, do not panic, look at the operation.
(1) edit /etc/httpd/conf/httpd.confthe configuration file.
Recommended vimeditor, command mode, press /the key and then type the cgisearch.
ScriptAlias cgi refers to the alias path, where we will change it ok, as shown below:
! [Change cgi alias] (https://img-blog.csdnimg.cn/20200304224650819.png
save and exit after the restart httpd configuration file to take effect and then try to access.
2, add CGI path
If you already have the path does not meet our needs, we do not panic, we own a plus.
Editing a configuration file step, edit the content as follows:
Here we add a web access path to hellothe actual file path is /var/www/hello/the path cgi program
We try to visit at:
Third, resolve python3 CGI output of Chinese garbage problem
1, garbled phenomenon
Access Effect:
Logging:
AH01215: UnicodeEncodeError: ‘ascii’ codec can’t encode characters in position 0-1: ordinal not in range(128)
2, the solution
1, plus the head of the program code is shown below:
#! /usr/bin/env python3
# -*- coding:UTF-8 -*-
import codecs, sys
sys.stdout = codecs.getwriter('utf-8')(sys.stdout.buffer)
print('Content-Type: text/html; charset=utf-8\n')
import os
print("hello")
print("你好")
print("<br>你的IP是：%s"%os.environ['REMOTE_ADDR'])
print ("<br>你的UA是：%s"%os.environ['HTTP_USER_AGENT'])
print("<br>你的请求端口是：%s"%os.environ['REMOTE_PORT'])
print("<br>你的请求路径是：http://anti-fraud.wiki%s"%os.environ['REQUEST_URI'])
print("<br>你的请求方法是：%s"%os.environ['REQUEST_METHOD'])
print("end")
In the first program header code above was added 3- 5, line, effect access as follows:
2, have been tested, the following header code equally effective
#! /usr/bin/env python3
# -*- coding:UTF-8 -*-
import io
import sys
sys.stdout = io.TextIOWrapper(sys.stdout.detach(),encoding='utf-8')
print('Content-Type: text/html; charset=utf-8\n')
四、Enjoy！
