Api 平台 3：DataTransformerInterface 问题

Question

I am learning to create DTO and DataTransformerInterface to send specific data in my response.

The issue is that the file "DataTransformerInterface" is missing. When I checked the "Api-Platform" folder, the Core folder is missing and when I verified on the git repository, the core folder is not available there.

I have searched through vendor and the file could not be found.

Did anybody run into this problem and manage to solve it?

Answer 1

There is no more DataTransformerInterface in API-Platform 3. You should implement your logic inside a stateProvider or a stateProcessor instead.

Look at this .
