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 copy

  1. echo ‘Old friends and old wines are best.’;

python发送get请求代码：

[python] view plain copy

  1. #!/usr/bin/env python
  2. #coding=utf8
  4. import httplib
  6. httpClient = None
  8. try:
  9. httpClient = httplib.HTTPConnection(‘localhost’, 80, timeout=30)
  10. httpClient.request(‘GET’, ‘/test.php’)
  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 copy

  1. var_dump($_POST);

python发起post请求代码：

[python] view plain copy

  1. #!/usr/bin/env python
  2. #coding=utf8
  4. import httplib, urllib
  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”}
  12. httpClient = httplib.HTTPConnection(“localhost”, 80, timeout=30)
  13. httpClient.request(“POST”, “/test.php”, params, headers)
  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()
