Use Python to make Post/get requests to the Web site

Take a friend's web job site as an example:

http://simpledating.sinaapp.com/

Web pages can be accessed using URLLIB2 in the standard library

GET:

Take a look at the normally issued GET request:

The code is as follows:

#coding: Utf-8ImportUrllib2
# OpenDebug LogEasy CommissioningHttpHandler = Urllib2. HttpHandler (DebugLevel=1) Httpshandler = Urllib2. Httpshandler (DebugLevel=1) opener = Urllib2.build_opener (HttpHandler, Httpshandler) Urllib2.install_opener (opener)Try: Header = {' Accept ':' */* ',        ' Accept-language ':' zh-cn,zh;q=0.8 ',        ' Connection ':' keep-alive ',        ' Host ':' simpledating.sinaapp.com ',        ' Origin ':' http://simpledating.sinaapp.com ',        ' Referer ':' http://simpledating.sinaapp.com/',        ' User-agent ':' mozilla/5.0 (Windows NT 6.3; WOW64) applewebkit/537.36 (khtml, like Gecko) chrome/35.0.1916.153 safari/537.36 SE 2.X METASR 1.0 ',    }

POST:

First look at the POST request that was sent normally:

can easily see the post data format is three, oh this site also added XSRF ( cross-site request forgery ), to prevent the forgery of the request.

Then I'm asking for data and cookies to be forged.

The code is as follows:

#coding: Utf-8ImportUrllibImportUrllib2# OpenDebug LogEasy CommissioningHttpHandler = Urllib2. HttpHandler (DebugLevel=1) Httpshandler = Urllib2. Httpshandler (DebugLevel=1) opener = Urllib2.build_opener (HttpHandler, Httpshandler) Urllib2.install_opener (opener)Try:#datais to submit the data according to the format he requested to fill in    data = {u ' _xsrf ':u ' f65fb8fdd4134e1f815c7a10f37561f6 ',u ' place ':u ' ~ ', u ' content ':u ' asdwqwt ', u ' time ':u ' 9999/99/99 ab:cd '} data = Urllib.urlencode (data) header = {' Accept ':' */* ',        # ' accept-encoding ': ' Gzip,deflate,sdch ',        ' Accept-language ':' zh-cn,zh;q=0.8 ',        ' Connection ':' keep-alive ',        ' Cookie ':' saeut=ckmpglsn3wdyh1mehbwpag==; user=eglvbmdiawfv|1421041643|f368e242dd53c65621ee754688042ae8898c572b;_ Xsrf=f65fb8fdd4134e1f815c7a10f37561f6 ',        ' Host ':' simpledating.sinaapp.com ',        ' Origin ':' http://simpledating.sinaapp.com ',        ' Referer ':' http://simpledating.sinaapp.com/createBroadDating ',        ' User-agent ':' mozilla/5.0 (Windows NT 6.3; WOW64) applewebkit/537.36 (khtml, like Gecko) chrome/35.0.1916.153 safari/537.36 SE 2.X METASR 1.0 ',        # Postto join the:        ' Content-type ':' application/x-www-form-urlencoded; Charset=utf-8 ',        ' Content-length ':' the ",        ' X-requested-with ':' XMLHttpRequest ',    } req = Urllib2. Request (URL=' http://simpledating.sinaapp.com/createBroadDating ',                    Data= Data,                    Headers= header) Response = Urllib2.urlopen (req)PrintResponse.read ()exceptUrllib2. Httperror, E:Print' ERROR ', E.code

The returned results are as follows:
