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()
