【整理】Python中用于解析Http数据包的模块/库

Python crifan 2931浏览 0评论

对于常见的http的数据包,比如

用Firebug抓取出来访问

http://www.songtaste.com/music/

时的:

http request请求头信息:

GET /music/ HTTP/1.1
Host: www.songtaste.com
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:17.0) Gecko/20100101 Firefox/17.0

http response响应头信息:

HTTP/1.1 200 OK

Proxy-Connection: Keep-Alive

对于这样的原始的http数据包,想要通过Python去解析的话,有哪些可用的库或模块。

去找了下,Python中的解析http数据包的库或模块有以下一些:

 

httpheader Python module

http://deron.meranda.us/python/httpheader/

源码下载:

httpheader.py

演示如何使用:

Using HTTP range requests

 

WebOb

http://webob.org/

下载页面:

http://pypi.python.org/pypi/WebOb/1.2.3

 

利用标准库中的BaseHTTPRequestHandler和StringIO

参考:

Parse raw HTTP Headers

有,利用标准库中的BaseHTTPRequestHandler和StringIO,演示代码:

from BaseHTTPServer import BaseHTTPRequestHandler
from StringIO import StringIO

class HTTPRequest(BaseHTTPRequestHandler):
    def __init__(self, request_text):
        self.rfile = StringIO(request_text)
        self.raw_requestline = self.rfile.readline()
        self.error_code = self.error_message = None
        self.parse_request()

    def send_error(self, code, message):
        self.error_code = code
        self.error_message = message

用法:

# Using this new class is really easy!

request = HTTPRequest(request_text)

print request.error_code       # None  (check this first)
print request.command          # "GET"
print request.path             # "/who/ken/trust.html"
print request.request_version  # "HTTP/1.1"
print len(request.headers)     # 3
print request.headers.keys()   # ['accept-charset', 'host', 'accept']
print request.headers['host']  # "cm.bell-labs.com"

# Parsing can result in an error code and message

request = HTTPRequest('GET\r\nHeader: Value\r\n\r\n')

print request.error_code     # 400
print request.error_message  # "Bad request syntax ('GET')"
