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()
