python之httplib模块

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

#!/usr/bin/python
import httplib

conn = httplib.HTTPConnection("www.csdn.net")
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:

200 OK
