CGI 脚本下载而不是运行
[英]CGI script downloads instead of running
问题描述
I'm running apache2 server.
我正在运行 apache2 服务器。 CGIHTTPServer is running in directory /mnt/hgfs/wind/BTech_BTP/BTP/code/final_code/ . CGIHTTPServer 在目录/mnt/hgfs/wind/BTech_BTP/BTP/code/final_code/ 中运行。 I'm using the url http://localhost:8000/test/www/adder.html .我正在使用网址http://localhost:8000/test/www/adder.html 。
I have three file in ../final_code/test/www directory.我在 ../final_code/test/www 目录中有三个文件。
adder.html contains: adder.html 包含：
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

adder.cgi contains adder.cgi 包含
#!/usr/bin/env python3
import cgi # NEW
def main(): # NEW except for the call to processInput
form = cgi.FieldStorage() # standard cgi script lines to here!
# use format of next two lines with YOUR names and default data
numStr1 = form.getfirst("x", "0") # get the form value associated with form
# name 'x'. Use default "0" if there is none.
numStr2 = form.getfirst("y", "0") # similarly for name 'y'
contents = processInput(numStr1, numStr2) # process input into a page
print(contents)
def processInput(numStr1, numStr2):
'''Process input parameters and return the final page as a string.'''
num1 = int(numStr1) # transform input to output data
num2 = int(numStr2)
total = num1+num2
return fileToStr('additionTemplate.html').format(**locals())
# standard code for future cgi scripts from here on
def fileToStr(fileName):
"""Return a string containing the contents of the named file."""
fin = open(fileName);
contents = fin.read();
fin.close()
return contents
try: # NEW
print("Content-type: text/html\n\n") # say generating html
main()
except:
cgi.print_exception() # catch and print errors
When i hit the submit button in browser, it downloads the adder.cgi file instead of executing it???当我点击浏览器中的提交按钮时，它会下载 adder.cgi 文件而不是执行它？？？
Also, if you need to see any configuration file, please do let me know.另外，如果您需要查看任何配置文件，请告诉我。
Edit1: this is my apache2.conf file after editing. Edit1：这是我编辑后的 apache2.conf 文件。
# This is the main Apache server configuration file. It contains the
# configuration directives that give the server its instructions.
# See http://httpd.apache.org/docs/2.4/ for detailed information about
# the directives and /usr/share/doc/apache2/README.Debian about Debian specific
# hints.
#
#
# Summary of how the Apache 2 configuration works in Debian:
# The Apache 2 web server configuration in Debian is quite different to
# upstream's suggested way to configure the web server. This is because Debian's
# default Apache2 installation attempts to make adding and removing modules,
# virtual hosts, and extra configuration directives as flexible as possible, in
# order to make automating the changes and administering the server as easy as
# possible.
# It is split into several files forming the configuration hierarchy outlined
# below, all located in the /etc/apache2/ directory:
#
# /etc/apache2/
# |-- apache2.conf
# | `-- ports.conf
# |-- mods-enabled
# | |-- *.load
# | `-- *.conf
# |-- conf-enabled
# | `-- *.conf
# `-- sites-enabled
# `-- *.conf
#
#
# * apache2.conf is the main configuration file (this file). It puts the pieces
# together by including all remaining configuration files when starting up the
# web server.
#
# * ports.conf is always included from the main configuration file. It is
# supposed to determine listening ports for incoming connections which can be
# customized anytime.
#
# * Configuration files in the mods-enabled/, conf-enabled/ and sites-enabled/
# directories contain particular configuration snippets which manage modules,
# global configuration fragments, or virtual host configurations,
# respectively.
#
# They are activated by symlinking available configuration files from their
# respective *-available/ counterparts. These should be managed by using our
# helpers a2enmod/a2dismod, a2ensite/a2dissite and a2enconf/a2disconf. See
# their respective man pages for detailed information.
#
# * The binary is called apache2. Due to the use of environment variables, in
# the default configuration, apache2 needs to be started/stopped with
# /etc/init.d/apache2 or apache2ctl. Calling /usr/bin/apache2 directly will not
# work with the default configuration.
# Global configuration
#
#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# NOTE! If you intend to place this on an NFS (or otherwise network)
# mounted filesystem then please read the Mutex documentation (available
# at <URL:http://httpd.apache.org/docs/2.4/mod/core.html#mutex>);
# you will save yourself a lot of trouble.
#
# Do NOT add a slash at the end of the directory path.
#
#ServerRoot "/etc/apache2"
#
# The accept serialization lock file MUST BE STORED ON A LOCAL DISK.
#
Mutex file:${APACHE_LOCK_DIR} default
#RemoveHandler cgi-script .cgi .pl .plx .ppl .perl .py
#
# PidFile: The file in which the server should record its process
# identification number when it starts.
# This needs to be set in /etc/apache2/envvars
#
PidFile ${APACHE_PID_FILE}
#
# Timeout: The number of seconds before receives and sends time out.
#
Timeout 300
#
# KeepAlive: Whether or not to allow persistent connections (more than
# one request per connection). Set to "Off" to deactivate.
#
KeepAlive On
#
# MaxKeepAliveRequests: The maximum number of requests to allow
# during a persistent connection. Set to 0 to allow an unlimited amount.
# We recommend you leave this number high, for maximum performance.
#
MaxKeepAliveRequests 100
#
# KeepAliveTimeout: Number of seconds to wait for the next request from the
# same client on the same connection.
#
KeepAliveTimeout 5
# These need to be set in /etc/apache2/envvars
User ${APACHE_RUN_USER}
Group ${APACHE_RUN_GROUP}
#
# HostnameLookups: Log the names of clients or just their IP addresses
# e.g., www.apache.org (on) or 204.62.129.132 (off).
# The default is off because it'd be overall better for the net if people
# had to knowingly turn this feature on, since enabling it means that
# each client request will result in AT LEAST one lookup request to the
# nameserver.
#
HostnameLookups Off
# ErrorLog: The location of the error log file.
# If you do not specify an ErrorLog directive within a <VirtualHost>
# container, error messages relating to that virtual host will be
# logged here. If you *do* define an error logfile for a <VirtualHost>
# container, that host's errors will be logged there and not here.
#
ErrorLog ${APACHE_LOG_DIR}/error.log
#
# LogLevel: Control the severity of messages logged to the error_log.
# Available values: trace8, ..., trace1, debug, info, notice, warn,
# error, crit, alert, emerg.
# It is also possible to configure the log level for particular modules, e.g.
# "LogLevel info ssl:warn"
#

# Sets the default security model of the Apache2 HTTPD server. It does

# The former is used by web applications packaged in Debian,

# your system is serving content from a sub-directory in /srv you must allow
# access here, or in any related virtual host.

In /etc/apache2/mods-available directory you can see the installed modules of apache2.在/etc/apache2/mods-available目录下可以看到apache2安装的模块。 cgi.load is the module for CGI files. cgi.load是 CGI 文件的模块。 It is not enabled by default.默认情况下不启用。 Use these commands to enable them.使用这些命令来启用它们。
$ cd /etc/apache2/mods-enabled
$ sudo ln -s ../mods-available/cgi.load
Then reload the server然后重新加载服务器
$ sudo service apache2 reload

You need to teach your Apache installation how to deal with CGI scripts by modifying your .conf file.您需要通过修改您的 .conf 文件来教您的 Apache 安装如何处理 CGI 脚本。 Check this link out.看看这个链接。 If your Apache server doesn't have instructions on how to deal with a .cgi extension then it will treat it as any other plain file on the server (which is to serve the file as a client-side file and not server-side code that should be executed/parsed).如果您的 Apache 服务器没有关于如何处理 .cgi 扩展名的说明，那么它会将其视为服务器上的任何其他纯文件（将文件作为客户端文件而不是服务器端代码提供）应该被执行/解析）。
An example configuration:一个示例配置：
DocumentRoot /var/www
<Directory /var/www/>
Options ExecCGI
AllowOverride None
Order allow,deny
Allow from all
AddHandler cgi-script .cgi
</Directory>

For Future seekers having the same problem here, it is the steps to set CGI correctly.对于在这里遇到同样问题的未来寻求者，这是正确设置CGI的步骤。 But usually step number 2 is responsible for downloading your CGI file instead of running it但通常第 2 步负责下载您的 CGI 文件而不是运行它
Make the following changes to your httpd.conf file :对 httpd.conf 文件进行以下更改：
- Uncomment or add
LoadModule cgi_module modules/mod_cgi.so取消注释或添加LoadModule cgi_module modules/mod_cgi.so - Find
<IfModule alias_module>Tag and add your script aliases to tell apache where your cgi directory should be mapped to something like this :ScriptAlias /gias/cgi-bin/ "${SRVROOT}/htdocs/gias/cgi-bin/"找到<IfModule alias_module>标签并添加你的脚本别名来告诉 apache 你的 cgi 目录应该映射到这样的地方：ScriptAlias /gias/cgi-bin/ "${SRVROOT}/htdocs/gias/cgi-bin/" Add your
<Directory>tag to give permission to your directory添加您的<Directory>标签以授予您目录的权限<Directory "${SRVROOT}/gias/cgi-bin"> AllowOverride None Options None Require all granted </Directory>
and Thats all!就这样！
NOTE : if you have multiple CGI, each in different directory then you should use AddHandler cgi-script .cgi inside a <IfModule>注意：如果你有多个 CGI，每个都在不同的目录中，那么你应该在<IfModule>使用AddHandler cgi-script .cgi

I note you have a CGI with python.我注意到你有一个带有 python的 CGI 。
First: you must install the python module for apache:首先：您必须为 apache 安装 python 模块：
In ubuntu for example is:例如在 ubuntu 中是：
sudo apt-get install libapache2-mod-python
Next you must configure apache so it can read python files:接下来，您必须配置 apache 以便它可以读取 python 文件：
Edit /etc/apache2/apache2.conf and add this lines to end of file: (change /var/www to your document root)编辑/etc/apache2/apache2.conf并将此行添加到文件末尾：（将 /var/www 更改为您的文档根目录）
<Directory /var/www/>
AddHandler mod_python .py
PythonHandler mod_python.publisher
</Directory>
And finally restart apache:最后重启apache：
sudo /etc/init.d/apache2 restart
