python发送HTTP请求

python发送HTTP请求 今天用python写一个发送HTTP请求的功能，查了下文档，发现实现也就4、5行左右，不禁感叹啊，查了下原来找的java实现的，相比还是臃肿了很多。 所以，python的好处还是蛮多的，对于 这些小的功能点相当适合。 附上官方的实例：

01 Here is an example session that uses the GET method:  

02    

03 >>> import httplib  

04 >>> conn = httplib.HTTPConnection("www.python.org")  

05 >>> conn.request("GET", "/index.html")  

06 >>> r1 = conn.getresponse()  

07 >>> print r1.status, r1.reason  

08 200 OK  

09 >>> data1 = r1.read()  

10 >>> conn.request("GET", "/parrot.spam")  

11 >>> r2 = conn.getresponse()  

12 >>> print r2.status, r2.reason  

13 404 Not Found  

14 >>> data2 = r2.read()  

15 >>> conn.close()  

16    

17 Here is an example session that uses the HEAD method. Note that the HEAD method never returns any data.  

18    

19 >>> import httplib  

20 >>> conn = httplib.HTTPConnection("www.python.org")  

21 >>> conn.request("HEAD","/index.html")  

22 >>> res = conn.getresponse()  

23 >>> print res.status, res.reason  

24 200 OK  

25 >>> data = res.read()  

26 >>> print len(data)  

27 0 

28 >>> data == ''  

29 True 

30    

31 Here is an example session that shows how to POST requests:  

32    

33 >>> import httplib, urllib  

34 >>> params = urllib.urlencode({'spam': 1, 'eggs': 2, 'bacon': 0})  

35 >>> headers = {"Content-type": "application/x-www-form-urlencoded",  

36 ...            "Accept": "text/plain"}  

37 >>> conn = httplib.HTTPConnection("musi-cal.mojam.com:80")  

38 >>> conn.request("POST", "/cgi-bin/query", params, headers)  

39 >>> response = conn.getresponse()  

40 >>> print response.status, response.reason  

41 200 OK  

42 >>> data = response.read()  

43 >>> conn.close()
