Bu eğitimde, MediaWiki Eylem API'si kullanarak bir Vikipedi:Günün seçkin resmi görüntüleyicisinin nasıl oluşturulacağını öğreneceksiniz. Kodu GitHub'dan indirin Toolforge'da uygulamaya göz atın

Bu eğitim size bunu kullanarak nasıl yapacağınızı öğretecektir:


 * Python 3 ve Flask çerçevesi
 * MediaWiki Eylem API'nin ve  modülleri

Python'u ayarlama
This tutorial uses Python 3. You can download the latest Python version from here:


 * Python for Windows 7, 8, and 10
 * Python for Mac OS X

See the Python beginner's guide for further instructions on installing Python on different operating systems.

Flask'ı ayarlama
Pip is a package manager that you can use to install Flask: . If you don't have pip already, install it from the official Pip website.

2. adım: Basit bir Flask uygulaması oluşturun
If you have everything successfully installed, place the following script in, inside your project folder: . When you run it, it should display "Hello world" at http://localhost:5000/ :

3. adım: Günün resmi görüntüleyicisi
Now that you have everything set up, you can start writing code for the Picture of the Day viewer. Picture of the day, or POTD, is a featured image displayed daily on the home page of Wikipedia. You'll be getting the picture from a wiki template that changes every day.

Bugünün tarihini almak
The first order of business is simply knowing what day it is. Because POTD updates daily, you need today's date to access the archives and get at a stable version of the correct picture. To do this, import Python's class.

Next, define a new function,. will render the web page and pass along any data associated with our API calls. See for more information on the   file we'll be using as a template. For now,  should contain a variable holding the current date. We'll be using it soon to compose a query to access the POTD.

Eylem API'sini çağırma
The Action API works by sending back data in response to HTTP requests. To do so, you will import the Python Requests library.

Next add two new variables:  and. You will use the  object to make requests to the   url.

In a new function,, call  to request the picture embedded within a protected POTD page (example). From this call, use the picture's filename to call, and retrieve the image's source url. In this example, the second API call is handled in the helper function,.

Wikipedia's archives lists dates by ISO standard format -- for instance, 2019-01-31, for 31 January, 2019. You can get the correct format by using the date method,.

Finally, alter  to call. Import  from , and make   return.

Flask templates mostly contain HTML markup, but they also use Jinja to render dynamic content. Jinja markup looks like this --  -- and is used to inject Python variables or expressions into our basic page structure. Add some basic HTML 5 boilerplate and a few elements to. Make sure to save it to a directory within your app, named.

Add a element to , and give it the following submit button inputs: Back and Next. When either button is selected, the form will submit a POST request, and the selected value will be passed back to. This will allow users to browse through the Picture of the Day archives.

Next, update  with a   function, for setting the date presented to the user. Also extend the  route to handle POST requests from the form. To allow  to read the POST request message, import Flask's   class.

The complete Python and HTML code:

Styling your app
Flask uses a directory, named static, to contain any helper files that stay the same throughout the lifecycle of the app. This is a useful place to put any stylesheets or additional scripts. Our stylesheet will be using some colors and visual motifs based on the Wikimedia Style Guide. Place a CSS file in.
