Python發送HTTP請求

python發送HTTP請求 今天用python寫一個發送HTTP請求的功能，查了下文檔，發現實現也就4、5行左右，不禁感歎啊，查了下原來找的java實現的，相比還是臃腫了很多。 所以，python的好處還是蠻多的，對於 這些小的功能點相當適合。 附上官方的實例：

1. 01 Here is an example session that uses the GET method:
3. 02
5. 03 >>> import httplib
7. 04 >>> conn = httplib.HTTPConnection("www.python.org")
9. 05 >>> conn.request("GET", "/index.html")
11. 06 >>> r1 = conn.getresponse()
13. 07 >>> print r1.status, r1.reason
15. 08 200 OK
17. 09 >>> data1 = r1.read()
19. 10 >>> conn.request("GET", "/parrot.spam")
21. 11 >>> r2 = conn.getresponse()
23. 12 >>> print r2.status, r2.reason
25. 13 404 Not Found
27. 14 >>> data2 = r2.read()
29. 15 >>> conn.close()
31. 16
33. 17 Here is an example session that uses the HEAD method. Note that the HEAD method never returns any data.
35. 18
37. 19 >>> import httplib
39. 20 >>> conn = httplib.HTTPConnection("www.python.org")
41. 21 >>> conn.request("HEAD","/index.html")
43. 22 >>> res = conn.getresponse()
45. 23 >>> print res.status, res.reason
47. 24 200 OK
49. 25 >>> data = res.read()
51. 26 >>> print len(data)
53. 27 0
55. 28 >>> data == ''
57. 29 True
59. 30
61. 31 Here is an example session that shows how to POST requests:
63. 32
65. 33 >>> import httplib, urllib
67. 34 >>> params = urllib.urlencode({'spam': 1, 'eggs': 2, 'bacon': 0})
69. 35 >>> headers = {"Content-type": "application/x-www-form-urlencoded",
71. 36 ... "Accept": "text/plain"}
73. 37 >>> conn = httplib.HTTPConnection("musi-cal.mojam.com:80")
75. 38 >>> conn.request("POST", "/cgi-bin/query", params, headers)
77. 39 >>> response = conn.getresponse()
79. 40 >>> print response.status, response.reason
81. 41 200 OK
83. 42 >>> data = response.read()
85. 43 >>> conn.close()
