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：

view sourceprint?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()
