python发送HTTP请求的方法小结

本文实例讲述了python发送HTTP请求的方法。分享给大家供大家参考。具体如下：

这里包含 Python 使用 GET/HEAD/POST 方法进行 HTTP 请求

1. GET 方法：

    >>> import httplib 
    >>> conn = httplib.HTTPConnection("www.python.org") 
    >>> conn.request("GET", "/index.html") 
    >>> r1 = conn.getresponse() 
    >>> print r1.status, r1.reason 
    200 OK 
    >>> data1 = r1.read() 
    >>> conn.request("GET", "/parrot.spam") 
    >>> r2 = conn.getresponse() 
    >>> print r2.status, r2.reason 
    404 Not Found 
    >>> data2 = r2.read() 
    >>> conn.close()

2. HEAD 方法：

    >>> import httplib 
    >>> conn = httplib.HTTPConnection("www.python.org") 
    >>> conn.request("HEAD","/index.html") 
    >>> res = conn.getresponse() 
    >>> print res.status, res.reason 
    200 OK 
    >>> data = res.read() 
    >>> print len(data) 
    0
    >>> data == '' 
    True

3. POST 方法：

    >>> import httplib, urllib 
    >>> params = urllib.urlencode({'spam': 1, 'eggs': 2, 'bacon': 0}) 
    >>> headers = {"Content-type": "application/x-www-form-urlencoded", 
    ...      "Accept": "text/plain"} 
    >>> conn = httplib.HTTPConnection("musi-cal.mojam.com:80") 
    >>> conn.request("POST", "/cgi-bin/query", params, headers) 
    >>> response = conn.getresponse() 
    >>> print response.status, response.reason 
    200 OK 
    >>> data = response.read() 
    >>> conn.close()

希望本文所述对大家的Python程序设计有所帮助。
