//You could use defer-recovery to handle all possible panic's 
func handelPanic(){
 if recoverPanic := recovery();recoverPanic != nil{
  fmt.Println("Panic is being recovered...")
   //Call function which you want to restart after panic is being recovered
 }
}    

func main() {
 defer handlePanic()
 //some code that needs to check err
 if err != nil{
     panic(err)
 }
}

上面下面的代码将简单地处理所有的恐慌，如果恢复使用在主函数内推迟。
