Topic on Extension talk:UserMerge/Archive 2

I would like to contribute with multiple user merge scripts. The motivation behind this approach is to merge a list of users without manually entering each user on Special:UserMerge page.

I spin up mediawiki using vagrant. It was running on localhost with administrator credentials (admin:vagrant). I created manually Testold, Testnew and Testold2,Testnew2 users. As a result Testold user should be merged to Testnew and Testold2 shoudl be merged to Testnew2.

Following steps are implemented in provided scripts:

  1. Retrieve login token via mediawiki API
  2. Logon as admin (or someone with usermerge privileges) using login token
  3. Retrieve csfr token via mediawiki API
  4. Loop over users to be merged and for each send post request using csfr token
