CGIHTTPServer
— 支持 CGI 的 HTTP 请求处理程序
¶
注意
The
CGIHTTPServer
module has been merged into
http.server
in Python 3. The
2to3
tool will automatically adapt imports when converting your sources to Python 3.
The
CGIHTTPServer
module defines a request-handler class, interface compatible with
BaseHTTPServer.BaseHTTPRequestHandler
and inherits behavior from
SimpleHTTPServer.SimpleHTTPRequestHandler
but can also run CGI scripts.
注意
This module can run CGI scripts on Unix and Windows systems.
注意
CGI scripts run by the
CGIHTTPRequestHandler
class cannot execute redirects (HTTP code 302), because code 200 (script output follows) is sent prior to execution of the CGI script. This pre-empts the status code.
The
CGIHTTPServer
模块定义了下列类：
CGIHTTPServer.
CGIHTTPRequestHandler
(
request
,
client_address
,
server
)
¶
This class is used to serve either files or output of CGI scripts from the current directory and below. Note that mapping HTTP hierarchic structure to local directory structure is exactly as in
SimpleHTTPServer.SimpleHTTPRequestHandler
.
The class will however, run the CGI script, instead of serving it as a file, if it guesses it to be a CGI script. Only directory-based CGI are used — the other common server configuration is to treat special extensions as denoting CGI scripts.
The
do_GET()
and
do_HEAD()
functions are modified to run CGI scripts and serve the output, instead of serving files, if the request leads to somewhere below the
cgi_directories
路径。
The
CGIHTTPRequestHandler
defines the following data member:
cgi_directories
¶
This defaults to
['/cgi-bin', '/htbin']
and describes directories to treat as containing CGI scripts.
The
CGIHTTPRequestHandler
defines the following methods:
do_POST
(
)
¶
This method serves the
'POST'
request type, only allowed for CGI scripts. Error 501, “Can only POST to CGI scripts”, is output when trying to POST to a non-CGI url.
Note that CGI scripts will be run with UID of user nobody, for security reasons. Problems with the CGI script will be translated to error 403.
For example usage, see the implementation of the
test()
函数。
