python用httplib模块发送get和post请求

转自：http://www.01happy.com/python-httplib-get-and-post/

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，test.php的内容就是输出一句话：

echo'Old friends and old wines are best.';

python发送get请求代码：

#!/usr/bin/env python
#coding=utf8

importhttplib

httpClient =None

try:
    httpClient =httplib.HTTPConnection('localhost', 80, timeout=30)
    httpClient.request('GET', '/test.php')

    #response是HTTPResponse对象
    response =httpClient.getresponse()
    printresponse.status
    printresponse.reason
    printresponse.read()
exceptException, e:
    printe
finally:
    ifhttpClient:
        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test.php内容，打印出$_POST数组：

var_dump($_POST);

python发起post请求代码：

#!/usr/bin/env python
#coding=utf8

importhttplib, urllib

httpClient =None
try:
    params =urllib.urlencode({'name': 'tom', 'age': 22})
    headers ={"Content-type": "application/x-www-form-urlencoded"
                    , "Accept": "text/plain"}

    httpClient =httplib.HTTPConnection("localhost", 80, timeout=30)
    httpClient.request("POST", "/test.php", params, headers)

    response =httpClient.getresponse()
    printresponse.status
    printresponse.reason
    printresponse.read()
    printresponse.getheaders() #获取头信息
exceptException, e:
    printe
finally:
    ifhttpClient:
        httpClient.close()

运行代码，在我的电脑上输出如下：
