//
middle.GET("/user/myFans", user.MyFans)defines a middle, and creates an interface, but if token is empty or token is illegal, I return json information in middle. My understanding is that the json error message is returned in middle, and the subsequent user.MyFans should not be executed, but the actual situation is that this is still executed, resulting in an output like this:
{"code":1001,"msg":""}{"code":0,"data":{"allFansNum":0,"directFans":0,"normalOperatorNum":0,"recommendFans":0,"superOperatorNum":0},"msg":"ok"}how to deal with the change here, directly output {"code": 1001, "msg": "system error"}, the subsequent code is not executed?
