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 httplib04 >>> conn = httplib.HTTPConnection("www.python.org")05 >>> conn.request("GET", "/index.html")06 >>> r1 = conn.getresponse()07 >>> print r1.status, r1.reason08 200 OK09 >>> data1 = r1.read()10 >>> conn.request("GET", "/parrot.spam")11 >>> r2 = conn.getresponse()12 >>> print r2.status, r2.reason13 404 Not Found14 >>> 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 httplib20 >>> conn = httplib.HTTPConnection("www.python.org")21 >>> conn.request("HEAD","/index.html")22 >>> res = conn.getresponse()23 >>> print res.status, res.reason24 200 OK25 >>> 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, urllib34 >>> 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.reason41 200 OK42 >>> data = response.read()43 >>> conn.close()
