    //我的粉絲
    middle.GET("/user/myFans", user.MyFans)

定義了一個(gè)middle，然后創(chuàng)建了一個(gè)接口，但是如果token為空，或者token非法的話，我在middle里面就返回了json信息。我的理解是在middle里面返回了json錯(cuò)誤信息了，后續(xù)的user.MyFans這個(gè)應(yīng)該不在執(zhí)行，但是實(shí)際情況是這個(gè)還是執(zhí)行了，導(dǎo)致輸出成這樣了：

{"code":1001,"msg":"系統(tǒng)錯(cuò)誤"}{"code":0,"data":{"allFansNum":0,"directFans":0,"normalOperatorNum":0,"recommendFans":0,"superOperatorNum":0},"msg":"ok"}

請(qǐng)問(wèn)這里改怎么處理,直接輸出{"code":1001,"msg":"系統(tǒng)錯(cuò)誤"}，后續(xù)代碼不在執(zhí)行？
