Add callback when go zero authentication is successful

[z913123456]

Go Zero has a callback after JWT authentication failure, and it is hoped that there will also be a callback when authentication is successful

[codeErrorSleep]

This scenario is quite special. Can you add another middleware to solve it

I can add a middleware to solve it, but it's tedious and requires that each API can be modified. I really hope to have such a feature to handle globally 王小刚 ***@***.***
