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.
Note:
This module can run CGI scripts on Unix and Windows systems;
on Mac OS it will only be able to run Python scripts within the same
process as itself.
Note:
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 module defines the following class:
| class 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 path.
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:
-
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()
function.
