Description

Python tools for WSGI applications. Fast HTTP request parsing, files uploads, HTTP requests security, etc.

Written in Cython it is compiled into native C code and works dozens times faster than standard cgi.FieldStorage. For example, on requsts containing three files attached with overall size of 15 MB it works >25 times faster that cgi module. Plus it reads data from wsgi.input by blocks, parses them on-the-fly and stores found files into temporary location, contraversal to cgi, which reads request data line-by-line and stores each part fully in memory.

Currently this module provides the following functionality:

1. HTTP requests parsing from WSGI environment. It provides PHP-like style of data representation. Thus it defines the following storages for handled request data with HttpRequest object:

• SERVER
• HEADERS
• BODY
• QUERY
• COOKIE
• FILES

2. Configurable limitations for HTTP request. Such limitations gives an ability to prevent WSGI application from been flooded via network with the large requests.Currently it's possible to limit:

• max allowed files to upload
• max request body size
• max file size in bytes per uploaded file
• enable/disable file uploads

3. Simple work with uploaded files through FileUploader

4. PHP-style parameters parsing. For example such QUERY_STRING

   foo[][bar]=1&foo[][baz]=2&foo[xyz]=777
   

will be parsed to the following Python's dictionary object:

	"foo" : {
    	0 : {
        	"bar" : 1
    	},
    	1 : {
        	"baz" : 2
    	},
    	"xyz" : 777
	}

The same rule works on BODY, QUERY, COOKIE and FILES storages of HttpRequest object.

Basic usage example:

import wsgikit

def my_wsgi_app( environ, start_response):
    status = '200 OK'
    response_headers = [('Content-type','text/plain')]
    start_response( status, response_headers)
    request = wsgikit.HttpRequest( environ)
    return wsgikit.PrettyDict.format( request.to_dict())
