可能的错误

代码 信息
badcontinue Invalid continue param. You should pass the original value returned by the previous query.
invalidparammix The alprop=ids parameter cannot be used with alunique.
This happens when you use alprop=ids and alunique together

补充资料

  • As with other link modules within the Action API , this module returns the titles of the pages that link to the namespace, not the exact URIs to those pages.
  • This module can be used as a generator.
  • Previous versions would return an error if the user tried to run this module as a generator, and alunique was set to true. This was altered in v1.24, to allow using the module as a generator even if alunique is true.
