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：

**\[php\]** [ view plain][view plain] [copy][view plain]

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

python发送get请求代码：

**\[python\]** [ view plain][view plain] [copy][view plain]

1.  \#!/usr/bin/env python
2.  \#coding=utf8
3.  
4.  import httplib
5.  
6.  httpClient = None
7.  
8.  try:
9.  httpClient = httplib.HTTPConnection('localhost', 80, timeout=30)
10. httpClient.request('GET', '/test.php')
11. 
12. \#response是HTTPResponse对象
13. response = httpClient.getresponse()
14. print response.status
15. print response.reason
16. print response.read()
17. except Exception, e:
18. print e
19. finally:
20. if httpClient:
21. 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。

2、python发送POST请求  
修改test.php内容，打印出$\_POST数组：

**\[php\]** [ view plain][view plain] [copy][view plain]

1.  var\_dump($\_POST);

python发起post请求代码：

**\[python\]** [ view plain][view plain] [copy][view plain]

1.  \#!/usr/bin/env python
2.  \#coding=utf8
3.  
4.  import httplib, urllib
5.  
6.  httpClient = None
7.  try:
8.  params = urllib.urlencode(\{ 'name': 'tom', 'age': 22\})
9.  headers = \{ "Content-type": "application/x-www-form-urlencoded"
10. , "Accept": "text/plain"\}
11. 
12. httpClient = httplib.HTTPConnection("localhost", 80, timeout=30)
13. httpClient.request("POST", "/test.php", params, headers)
14. 
15. response = httpClient.getresponse()
16. print response.status
17. print response.reason
18. print response.read()
19. print response.getheaders() \#获取头信息
20. except Exception, e:
21. print e
22. finally:
23. if httpClient:
24. httpClient.close()
