MediaWiki Eylem API'sine genel bakış

MediaWiki Eylem API'si, kullanıcıların aşağıdaki gibi belirli sayfa oluşturma, kimlik doğrulama, ayrıştırma, arama vb. viki eylemlerini gerçekleştirmesine olanak tanıyan bir REST'li web hizmetidir. API:Anasayfa , API'yi anlamak için iyi bir başlangıç noktasıdır.

Programınız, viki özelliklerine erişim elde etmek için API'ye istek gönderir. Örneğin, bir vikide oturum açın, bir sayfa oluşturun ve düzenleyin, bir başlık arayın, içerik metni arayın veya içeriği ayrıştırın. Eylem API, üçüncü taraf geliştiriciler, Wikimedia uzantı geliştiricileri ve wiki sitesi yöneticileri tarafından kullanılabilir.

On the right sidebar of this page, there are many features that are supported by the API, grouped by category. Before sending requests to a wiki server, first read through the overview pages such as data formats, errors and warnings, and the Action API FAQ.

MediaWiki Eylem API'si nasıl kullanılır

You can request for data from client side to the server over HTTP and get the response back in a standard format (typically JSON). A request consists of an endpoint and a set of parameters. There are two types of request that can be made: GET and POST. For a GET request, a parameter would contain a query string in the URL. For a POST request, format the parameters in JSON format.

İstek biçimi

All Wikimedia Wikis have endpoints in this format http://example.org/w/api.php. To operate on the MediaWiki main site or English Wikipedia, use the related endpoint. For example, the English Wikipedia is at https://en.wikipedia.org/w/api.php For testing new accounts or test edits to pages, use the test wiki endpoint https://test.wikipedia.org/w/api.php.

In the query string in the URL, add the action parameter. It tells the API which action to perform. The most popular action is query (the URL would contain action=query), which allows fetching data from a wiki. Following the action parameter, add another parameter to indicate which one of the three query module types you want to perform:

  • prop - get properties of pages  
  • list - get list of pages matching a certain criterion
  • meta - get meta information about the wiki and user

Finally, include the format parameter, which tells the API in which format to get the results. The recommended format is JSON. The API has supported other output formats in the past, but they are not generally recommended.

 
Request format

Basit bir sorgu

Let’s take an example of a simple query to understand what a typical GET request and response would look like in the context of the Action API.

Let's search for a title in a wiki. We will use the search module documented on API:Search .

GET isteği

To search for page titles or content matching Craig Noone, the URL for the HTTP GET request would be:

Explanation of each part of the URL:

  • http://en.wikipedia.org/w/api.php is the main endpoint. In this case it is English Wikipedia.
  • action=query means fetch data from wiki.
  • list=search means get list of pages matching a criteria.
  • srsearch=Craig%20Noone indicates the page title or content to search for. The %20 indicates a space character in a URL.
  • format=json indicates JSON output, which is the recommended output format.

Response

The response is a JSON format document with a list of pages titles that match Craig Noone:

{
    "batchcomplete": "",
    "continue": {
        "sroffset": 10,
        "continue": "-||"
    },

            ...
        ]
    }
}

Examples of projects using Action API

Some example of projects in Wikimedia that use Action API:

  • Wikipedia iOS App, in which one of the features is to search for wiki pages near your location.
  • Bots that operate on a wiki. Pywikibot is a bot framework written in Python that interfaces with MediaWiki API which a lot of bot developers use.
  • API use in visualizing data obtained from a wiki. Such as this neat visualization that shows real time edits made on Wikipedia.

Additional notes

  • Several sites are using MediaWiki. They might all be running a different version of MediaWiki and in turn the API. Some module parameters supported in one version might be deprecated or removed in others. You could learn about that in each module's documentation via API help module.
  • If you want to make a lot of API calls, and perhaps run very busy and active bots, talk to wiki admins ahead of time, so they do not block you. See list of Administrators of Wikimedia projects. Read more about this topic on API:Etiquette .
  • All data modifying actions such as logging, editing or moving a page, and watching or patrolling changes would require tokens. You would need to obtain tokens via API:Tokens to proceed further.
