In Tornado 1.0, the SHA1 is used for signing, and the new version in Tornado 4.0 is signed with SHA256 and the output cookie format is different-the first number is the version number (secure The version used by cookies, not tornado versions. The new version of the Set_secure_cookie settings cookies related to the source code as follows: The code is

Because the Tornado built-in asynchttpclient function is too simple, so I wrote a tornado based HTTP client library, in view of the use of the library in many places, so extracted from the project, written in a separate library tornadohttpclient Tornadohttpclient is a tornado efficient asynchronous HTTP client library that supports cookies and proxies that are c

Tornado Handler Call CharacteristicsCalling methods in other tornado handler in a single tornado request, such as the Run method IntroductionIn the background development, sometimes need to do some of the functions of integration, such as the request for the completion of a single function, and now there is a demand, need to complete these three functions, if the

that the data is stored in the "message" field, as you can see from the code above.So the background parsing data from the message, we remember is the Get_argument method.So the python code behind the scenes is: ImportTornado.ioloopImportTornado.webclassMainHandler (tornado.web.RequestHandler):defGet (self): Self.render ("ajax.html")classAjaxhandler (tornado.web.RequestHandler):defpost (self):#self.write ("Hello World")Self.write (Self.get_argument ("message")) Application=Tornado.web.Applicati

This article mainly introduces how tornado can capture and handle 404 errors. The method is simple. You only need to override the write_error method, the code below shows the errors in the path request listed in handlers. If only one rule (r "/hello", HelloHandler) is defined, only requests with undefined paths such as/hello/other can be captured, the default 404 error page of Tornado is displayed direct

With tornado, it is generally used to fetch the asynchttpclient. We can refer to fetch, use the Tornado feature, write the asynchronous callback programFirst look at the implementation of fetch, the key is to use the futuredefFetch (self, request, callback=none, * *Kwargs):"""executes a request, asynchronously returning an ' HttpResponse '. The request is either a string URL or an ' HttpRequest ' obj

As mentioned in Tornado, only errors in path requests listed in handlers can be captured. If only one rule (r "/hello", HelloHandler) is defined, only requests with undefined paths such as/hello/other can be captured, the default 404 error page of Tornado is displayed directly, such as/he,/helloworld, And/he/other, without displaying custom error pages. The solution is simple. You only need to add one (r ".

With the tornado is really comfortable, a lot of things for you to do.But there are also unsatisfactory places--for me, a neat freak, the automatic printing of my console without my control is intolerable.Connect to a new place and if it fails, Tornado uses the Python log to write the error like the console.In order to eliminate this error and not lose this record, transfer to the file, which can be done:Ge

Tornado is very simple to build, use Pip, or download source code can be.
