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，test.php的内容就是输出一句话：

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

python发送get请求代码：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

#!/usr/bin/env python #coding=utf8   import httplib   httpClient = None   try:     httpClient = httplib.HTTPConnection('localhost', 80, timeout=30)     httpClient.request('GET', '/test.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test.php内容，打印出$_POST数组：

1	var_dump($_POST);

python发起post请求代码：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

#!/usr/bin/env python #coding=utf8   import httplib, 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()     print response.status     print response.reason     print response.read()     print response.getheaders() #获取头信息 except Exception, e:     print e finally:     if httpClient:         httpClient.close()

运行代码，在我的电脑上输出如下：
