python用httplib模块发送get和post请求

在python中，模拟http客户端发送get和post请求，主要用httplib模块的功能。

1、python发送GET请求

我在本地建立一个测试环境，python.php的内容就是输出一句话：

python发送get请求代码：

#!/usr/bin/env python
# -*- coding: gbk -*-
# -*- coding: utf-8 -*-
# Date: 2014/8/19
# Created by 独自等待
# 博客 http://www.waitalone.cn/
import httplib

httpClient = None

try:
    httpClient = httplib.HTTPConnection('localhost', 80, timeout=10)
    httpClient.request('GET', '/python.php')

    # response是HTTPResponse对象
    response = httpClient.getresponse()
    print response.status
    print response.reason
    print response.read()
except Exception, e:
    print e
finally:
    if httpClient:
        httpClient.close()

上面代码中使用了finally来保证即使出错的时候也能关闭httpClient。运行这个程序，在我的电脑上输出结果如下：

2、python发送POST请求

修改python.php内容，打印出$_POST数组：

python发起post请求代码：

#!/usr/bin/env python
# -*- coding: gbk -*-
# -*- coding: utf-8 -*-
# Date: 2014/8/19
# Created by 独自等待
# 博客 http://www.waitalone.cn/
import urllib, httplib

httpClient = None
try:
    params = urllib.urlencode({'name': 'waitalone.cn', 'age': '5'})
    headers = {'Content-type': 'application/x-www-form-urlencoded', 'Accept': 'text/plain'}
    httpClient = httplib.HTTPConnection('localhost', 80, timeout=10)
    httpClient.request('POST', '/python.php', params, headers)
    response = httpClient.getresponse()
    print response.status
    print response.reason
    print response.read()
    print response.getheaders()
except Exception, e:
    print e
finally:
    if httpClient:
        httpClient.close()

友情提示：

在http操作中，有时会需要了解一些http协议的相关内容，可以前往w3c查看：http://www.w3.org/Protocols/rfc2616/rfc2616.html
