http-parser 0.2.0

http request/response parser

http-parser

HTTP request/response parser for Python in C under MIT License, based on http-parser from Ryan Dahl.

Project url: https://github.com/benoitc/http-parser/

Requirements:

• Python 2.6 or sup.

• Cython if you need to rebuild the C code

Installation

$ pip install http-parser

Or install from source:

$ git clone git://github.com/benoitc/http-parser.git
$ cd http-parser && python setup.py install

Usage

http-parser provide you parser.HttpParser low-level parser in C that you can access in your python program and http.HttpStream providing higher-level access to a readable,sequential io.RawIOBase object.

To help you in your day work, http-parser prvides you 3 kind of readers in the reader module: IterReader to read iterables, StringReader to reads strings and StringIO objects, SocketReader to read sockets or objects with the same aî (recv_into needed). You cnan of course use any io.RawIOBase object.

Likre http-parser in C you can pass your own callbacks to the C parser, so you can eventually parse asynchronously any HTTP stream. Callbacks are:

on_message_begin()
on_path(path)
on_query_string(query_string)
on_url(url)
on_fragment(fragment)
on_header_field(field, last_was_value)
on_header_value(key, value)
on_headers_complete()
on_body(chunk)
on_message_complete()

Example of HttpStream

ex:

#!/usr/bin/env python
import socket

from http_parser.http import HttpStream
from http_parser.reader import SocketReader

def main():
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    try:
        s.connect(('gunicorn.org', 80))
        s.send("GET / HTTP/1.1\r\nHost: gunicorn.org\r\n\r\n")
        r = SocketReader(s)
        p = HttpStream(r)
        print p.headers()
        print p.body_file().read()
    finally:
        s.close()

if __name__ == "__main__":
    main()

Example of HttpParser:

#!/usr/bin/env python
import socket

from http_parser.parser import HttpParser


def main():

    p = HttpParser()
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    body = []
    try:
        s.connect(('gunicorn.org', 80))
        s.send("GET / HTTP/1.1\r\nHost: gunicorn.org\r\n\r\n")

        while True:
            data = s.recv(1024)
            if not data:
                break

            recved = len(data)
            nparsed = p.execute(data, recved)
            assert nparsed == recved

            if p.is_headers_complete():
                print p.get_headers()

            if p.is_partial_body():
                body.append(p.recv_body())

            if p.is_message_complete():
                break

        print "".join(body)

    finally:
        s.close()

if __name__ == "__main__":
    main()
