API:Article ideas generator/de

Überblick
In dieser Anleitung wirst du eine Demo einer Artikel-Ideen-Generator-App erhalten, die Artikel aus unterschiedlichen Kategorien vorschlägt, die in der englischsprachigen Wikipedia noch nicht existieren.

Laden den Code von GitHub herunter Durchsuche die App auf Toolforge

In diesem Lernprogramm lernst du, wie du dies tun kannst:


 * Python- und Flask-Framework
 * Parsing- und Link-Module der MediaWiki Action API

Eine Schritt-für-Schritt-Anleitung, um diese Anwendung zu erstellen:

Schritt 1: Python- und Flask-Entwicklungsumgebung aufsetzen
Um die Python-Entwicklungsumgebung für eine Flask-Anwendung aufzusetzen, musst du Python installieren, eine virtuelle Umgebung erstellen und Flask installieren.

Lerne hier mehr über die Unterschiede zwischen Python2 und Python3. Um Python3 auf deiner lokalen Maschine zu installieren, befolge die Schritt-für-Schritt-Anleitung aus dem Installations-Leitfaden.

Die Entwicklungsumgebung, um die Anwendung aufzubauen, wird wie folgt aufgesetzt:

Eine einfache statische Seite rendern
Setze den folgenden Code in  ein

Setze die Code-Zeile Article ideas generator in eine HTML-Datei im Ordner  ein:

Führe deine Flask-App mit dem Befehl  aus und öffne , um dir deine App im Browser anzusehen. Du solltest "Article ideas generator" in deinem Browser-Fenster sehen können.

Style your app
Let's do some app styling. To do so, add link tags to load an external and internal stylesheet. External stylesheet, in this case, is the URL of a CSS file for a Google Font.

Replace the existing code in  with the following:

Place the following code in

Application layout
$HOME/article-ideas-generator ├── templates/ │  └── articles.html ├── static/ │  └── static.css ├── articles.py └── venv/

Step 3: Fetch page sections from Wikipedia:Requested articles
Let's write some code in a  function in   to fetch page sections from Wikipedia:Requested articles. This function takes page name as an argument and makes a  request to the Action API to parse sections of the page. API call consists of an endpoint  and query string parameters. Some of the key parameters are:


 * - module to parse content on a page
 * - page title to parse
 * - tells which piece of information to retrieve, in this example it is sections

Next, extend the Python Flask route  in   to call the function defined above and also pass the results returned by the function to.

Place the following Jinja template code in. It dynamically renders an array of buttons with help from page sections data as categories obtained via the API above.

Place the following code in  for button styling.

Step 4: Get more sections based on user selection
Based on a category or section user chooses in the previous step, fetch subsections from Wikipedia:Requested articles. Extend the Python Flask route  in   to handle POST requests. You can do so by adding both  and   in the   argument list in the route decorator. You can then obtain category selection available in a  format from the   object, which is passed to   function for further processing.

Step 5: Collect and display articles with missing links
Let's write some code in a  function in   to fetch around 20 articles with missing links on a page. This function takes page name as an argument and makes a  request to the Action API and return all links embedded on the provided page. From further extraction, you can obtain those links that are missing and don't yet exist on English Wikipedia. API call consists of an endpoint  and query string parameters. Some of the key parameters are:


 * - module to query information
 * - page title to collect links
 * - query module's submodule  used as a generator module to get a set of links embedded on a page
 * - number of links to fetch

Next, extend the  block concerning the   method in   route in   to call the   function if the page from which the request is obtained is of type.

Place the following Jinja template code in. It dynamically renders a list of links with help from the data obtained via the API above.
