Hello,

I’m a new user of Wikipedia. My username is Yuer3677.

I’m a senior student in BUPT China, since I am working on my graduating thesis, which is related to Wikipedia, I really need to get the deleted revision information.

I try to use action=“query” and list=” deletedrevs”, but the result is

 <?xml version="1.0"?>

<api servedby="mw1192">

  <error code="drvpermissiondenied" info="You don’t have permission to view deleted revision information" xml:space="preserve">See https://en.wikipedia.org/w/api.php for API usage</error>

</api>

  So, I want to know why I can’t view the deleted revision information? Since I really need the data to do my research, what can I do to get the information?

  Please help me. Thanks a lot!
