解决问题:当redis服务端断开的时候`进程会崩溃(转载6哥笔记)

 package main

 import (
     "fmt"
     "github.com/astaxie/beego/logs"
     "github.com/garyburd/redigo/redis"
     "ha666/initial"
     _ "ha666/initial"
     "strconv"
     "time"
 )

 func main() {
     defer func() {
         if err := recover(); err != nil {
             logs.Error("【main】ex:%v", err)
             time.Sleep(time.Second)
         }
     }()
     logs.Info("开始")
     rc := initial.RedisClient.Get()
     defer rc.Close()
     for {
         bytesresult, err := redis.ByteSlices(rc.Do("TIME"))
         if err != nil {
             fmt.Println(err.Error())
             return
         }
         for _, v := range bytesresult {
             _, err = strconv.ParseInt(string(v), , )
             if err != nil {
                 fmt.Println(err.Error())
                 return
             }
             //fmt.Println(il)
         }
         time.Sleep( * time.Millisecond)
     }
 }

上面犯了两个错误：

1、defer使用错误

2、redis客户端从pool取出来以后要判断错误

修正后的代码是这样的：

 package main

 import (
     "fmt"
     "github.com/astaxie/beego/logs"
     "github.com/garyburd/redigo/redis"
     "github.com/pkg/errors"
     "ha666/initial"
     _ "ha666/initial"
     "strconv"
     "time"
 )

 func main() {
     for {
         bytesresult, err := get_redis()
         if err != nil {
             fmt.Println(err.Error())
             continue
         }
         for _, v := range bytesresult {
             il, err := strconv.ParseInt(string(v), , )
             if err != nil {
                 fmt.Println(err.Error())
                 continue
             }
             fmt.Println(il)
         }
         time.Sleep( * time.Millisecond)
     }
 }

 func get_redis() ([][]byte, error) {
     rc := initial.RedisClient.Get()
     if rc.Err() != nil {
         return nil, rc.Err()
     }
     defer rc.Close()
     bytesresult, err := redis.ByteSlices(rc.Do("TIME"))
     return bytesresult, err
 }
