I have to capture all request of apache web server with mod_wsgi. Checking attacks of GET request.

You cannot use mod_wsgi to capture any request to Apache. All you could do this it make use of a WSGI middleware to capture particulars for demands starting a particular WSGI application. See:

http://code.google.com/p/modwsgi/wiki/DebuggingTechniques#Tracking_Request_and_Response

BTW, your requirement is vague in regards to what exactly you need to catch. It's also wise to search for other purpose built Apache modules. A module supporting utilization of a particular language is not going that will help you.
