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：
>>>importhttplib
>>>conn=httplib.HTTPConnection("www.python.org")
>>>conn.request("GET","/index.html")
>>>r1=conn.getresponse()
>>>printr1.status,r1.reason
200OK
>>>data1=r1.read()
>>>conn.request("GET","/parrot.spam")
>>>r2=conn.getresponse()
>>>printr2.status,r2.reason
404NotFound
>>>data2=r2.read()
>>>conn.close()
2.HEAD方法：
>>>importhttplib
>>>conn=httplib.HTTPConnection("www.python.org")
>>>conn.request("HEAD","/index.html")
>>>res=conn.getresponse()
>>>printres.status,res.reason
200OK
>>>data=res.read()
>>>printlen(data)
0
>>>data==''
True
3.POST方法：
>>>importhttplib,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()
>>>printresponse.status,response.reason
200OK
>>>data=response.read()
>>>conn.close()
希望本文所述对大家的Python程序设计有所帮助。
