我是靠谱客的博主大力大米，最近开发中收集的这篇文章主要介绍Python httplib模块使用实例，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

httplib模块是一个底层基础模块,实现的功能比较少,正常情况下比较少用到.推荐用urllib, urllib2, httplib2.

HTTPConnection 对象

class httplib.HTTPConnection(host[, port[, strict[, timeout[, source_address]]]])

创建HTTPConnection对象

HTTPConnection.request(method, url[, body[, headers]])

发送请求

HTTPConnection.getresponse()

获得响应

HTTPResponse对象

HTTPResponse.read([amt])
Reads and returns the response body, or up to the next amt bytes.

HTTPResponse.getheader(name[, default])

获得指定头信息

HTTPResponse.getheaders()

获得(header, value)元组的列表

HTTPResponse.fileno()

获得底层socket文件描述符

HTTPResponse.msg

获得头内容

HTTPResponse.version

获得头http版本

HTTPResponse.status

获得返回状态码

HTTPResponse.reason

获得返回说明

实例

复制代码代码如下:

#!/usr/bin/python
import httplib

conn = httplib.HTTPConnection("www.uoften.com")
conn.request("GET", "/")
r1 = conn.getresponse()

print r1.status, r1.reason
print '-' * 40

headers = r1.getheaders()
for h in headers:
print h
print '-' * 40

print r1.msg

输出:

复制代码代码如下:

200 OK
