python用httplib模块发送get和post请求

Python 80368浏览 0评论

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

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:

var_dump($_POST);

python发起post请求代码:

#!/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:

友情提示:

在http操作中,有时会需要了解一些http协议的相关内容,可以前往w3c查看:http://www.w3.org/Protocols/rfc2616/rfc2616.html
