POST request to import a page from another wiki (transwikiing) or from an xml file.
Dokumentacja API
Import process
Importing a page is a multi-step process:
- Log in using one of the methods described in API:Logowanie .
- GET a CSRF token . This token is the same for all pages but changes at every login.
- Send a POST request with the CSRF token in order to import the page.
The code samples below cover the third step in detail.
Example 1: Import a page from another wiki
Żądanie POST
Import Help:Rozszerzenie:Funkcje parsera to the Manual namespace (namespace 100) with full history.

Example 2: Import a page by uploading its xml dump
Żądanie POST
Import Help:Rozszerzenie:Funkcje parsera by uploading its xml dump obtained from Special:Export.
When uploading a file, you need to use multipart/form-data
as Content-Type or enctype, application/x-www-form-urlencoded
will not work.
xml
is not a file name, but the actual content of a file.api.php? action=import& xml=xmlcontentgoeshere& interwikiprefix=meta& token=123ABC [wypróbuj w ApiSandbox]

Dodatkowe informacje
- This module cannot be used as a generator .
importupload
rights are required in order to upload an xml file, whileimport
rights are required for interwiki imports.
- If you get a
Missing boundary in multipart/form-data POST data
error, it is because you sent it url-encoded but claimed it would be multipart/form-data.
MediaWiki is looking for a boundary in the header but cannot find it.
- Parameters marked with
upload
are only used when importing an uploaded XML file.
Similarly, parameters marked with interwiki
are only used when importing from another wiki (transwiki).
- The possible values for the
interwikisource
parameter differ per wiki, see Manual:$wgImportSources .
If the list of possible values for this parameter is empty, interwiki imports are disabled.
