1.首先在logger包下
點選檢視程式碼
package logger

func Recover(c *gin.Context) {

f.Close()
c.JSON(http.StatusOK, gin.H{

"msg": fmt.Sprintf("%v", err),
})
//終止後續介面呼叫，不加的話recover到異常後，還會繼續執行介面裡後續程式碼
c.Abort()
}
}()
c.Next()
}
點選檢視程式碼
r := gin.Default()
r.Use(gin.LoggerWithConfig(logger.LoggerToFile()))
r.Use(logger.Recover)
r.run(":7777")
