wordpress 在 apache2 上运行 python 作为 cgi
[英]wordpress on apache2 running python as cgi
问题描述
So here is what I want to do:
所以这就是我想做的：
On my Raspi a python program is running.在我的 Raspi 上，一个 python 程序正在运行。 On a wordpress site the current state of the program should be displayed and some configurations should be changeable.在 wordpress 站点上，应显示程序的当前 state，并且某些配置应该可以更改。
Here is the problem:这是问题所在：
Whenever I want to execute the python script, I get a 500 error code.每当我想执行 python 脚本时，我都会收到 500 错误代码。 It doesn't matter if I just want to display the value or change it.如果我只想显示值或更改它并不重要。 I'm new to html, cgi and apache, tried a lot but now I have no clue how to continue.我是 html、cgi 和 apache 的新手，尝试了很多但现在我不知道如何继续。 I'd appreciate it a lot if someone could point me in the right direction.如果有人能指出我正确的方向，我将不胜感激。
Here are my configurations:这是我的配置：
Apache: Apache：
Edited the file /etc/apache2/apache2.conf:编辑文件 /etc/apache2/apache2.conf：
<Directory /var/www/>
Options +ExecCGI +Indexes +FollowSymLinks
AddHandler cgi-script .cgi .py
AllowOverride None
Require all granted
</Directory>
<Directory "/var/www/cgi-bin">
AllowOverride None
Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
Require all granted
</Directory>
<Directory "/var/www/cgi-bin">
Options All
</Directory>
I also ran sudo a2enmod cgi我也跑了sudo a2enmod cgi
The webserver directory (/var/www/) looks like this: Web 服务器目录 (/var/www/) 如下所示：
.
├── cgi-bin
└── html
├── pma
│ └── ...
└── wordpress
└── ...
Wordpress: Wordpress：
On a wordpress site, I go into the "text" mode and have the following html code:在 wordpress 站点上，我 go 进入“文本”模式并具有以下 html 代码：
Curent Value: <form action="/cgi-bin/apfautostartval.py" method="get"></form>
<form action="/cgi-bin/apfcgi.py" method="post" target="_blank">
<input name="autoTest" type="radio" value="True" /> True (do automatic scan)
<input name="autoTest" type="radio" value="False" /> False (do manual scan)
<input type="submit" value="Submit" /></form>
Python files: Python 个文件：
The apfautostartval.py should just get the value from the config.ini and post it: apfautostartval.py 应该只从 config.ini 中获取值并将其发布：
#!/usr/bin/python3
import configparser
import os
import cgi, cgitb
cgitb.enable()
# Create config parser
config = configparser.ConfigParser()
configFilePath = os.path.join(os.path.sep,"home","pi",..., "config.ini")
config.read(configFilePath)
print("Content-type: text/html")
print()
print("<!DOCTYPE html>")
print("<html>")
print("<body>")
print(str(config['SETTINGS']["autoTest"]))
print("</body>")
print("</html>")
And finally the apfcgi.py should receive the submitted new value and write it to the config.ini:最后 apfcgi.py 应该接收提交的新值并将其写入 config.ini：
#!/usr/bin/python3
import configparser
import os
import cgi, cgitb
# Create instance of FieldStorage
form = cgi.FieldStorage()
cgitb.enable()
# Create config parser
config = configparser.ConfigParser()
configFilePath = os.path.join(os.path.sep,"home","pi",..., "config.ini")
print("Content-type: text/html")
print()
print("<!DOCTYPE html>")
print("<html>")
print("<body>")
# Receive autotest command from web site
if form.getvalue("autoTest"):
config.read(configFilePath)
if form.getvalue("autoTest").lower() == "true":
config['SETTINGS']["autoTest"] = "True"
else:
config['SETTINGS']["autoTest"] = "False"
with open(configFilePath, 'w') as configfile:
config.write(configfile)
print("</body>")
print("</html>")

I had the same problem.我有同样的问题。 The problem was in the encoding.问题出在编码上。 By default, ConfigParser.read() uses the encoding=none parameter.默认情况下，ConfigParser.read() 使用encoding=none参数。 I specified utf-8 and it worked.我指定了 utf-8，它起作用了。
config = configparser.ConfigParser()
config.read(configFilePath, encoding='utf-8')

Ok I have found the solution for one part of the problem: 好的，我已经找到了解决问题的一部分的方法：
When changing the value make sure, you granted permissions to the file for cgi scripts: 更改值时，请确保已为cgi脚本授予了该文件的权限：
in /etc/apache2/apache2.config add: 在/etc/apache2/apache2.config中添加：
<Directory "/home/pi/dirToTheConfigFile/">
Options +ExecCGI +Indexes +FollowSymLinks
AddHandler cgi-script .cgi .py
AllowOverride None
Require all granted
</Directory>
And make sure, the user www-data is allowed to modify the file. 并确保允许用户www-data修改文件。
In general add cgitb.enable() to your python scripts, so for html 500 errors you will get a detailed error message in the /var/log/apache2/error.log file 通常将cgitb.enable()添加到python脚本中，因此对于html 500错误，您将在/var/log/apache2/error.log文件中获得详细的错误消息。
For receiving data the following Solution was found: The Python script was unfortunately owned by root and therefore cound not be executed. 为了接收数据，找到了以下解决方案：不幸的是，Python脚本是root拥有的，因此无法执行cound。 I changed the permissions. 我更改了权限。
The receiving html in the wordpress has been rewritten, too: WordPress中的接收html也已被重写：
<iframe src="/cgi-bin/apfautostartval.py" width="100" height="29.5" frameborder="0" marginwidth="8" marginheight="0" scrolling="no" align="bottom"></iframe>
It's now an iframe and displays whatever is returned. 现在是iframe，并显示返回的内容。
