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 #!/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。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 #!/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()

运行代码,在我的电脑上输出如下:
