Thank you very much. I have reviewed the corresponding documents, but there are still some difficulties for me as I do not have a complete example

I expect to obtain the content returned by the interface, then determine whether the interface content meets a certain condition, and then call another service's interface query. Based on the queried content, I rewrite the interface return and return the rewritten content to the frontend

I am unable to retrieve the content returned by the interface
