环境: go1.14 gf v1.16.4

使用官方redis示例做压测,发现压测后不能正常连接redis,使用原生的redisgo或者go-redis在gf下压测没用问题,以下是压测的步骤和结果:

` [root@centos7 bin]# curl http://10.11.81.174:9999

[root@centos7 bin]# ./wrk -c5000 -d10 -t4 -T3 --latency http://10.11.81.174:9999

[root@centos7 bin]# ` 压完访问会提示write tcp 127.0.0.1:47785->127.0.0.1:6379: use of closed network connection

附件是我使用的代码 main.zip

试了一下你的代码,好像没有用到连接池 试试加这一行:conn = redisInstance.Conn()

s.BindHandler("/", func(r *ghttp.Request) {
        // 加这一行
        conn = redisInstance.Conn()

        v, err := conn.Do("GET", "k")
        fmt.Println(v)
        if err != nil {
            r.Response.Write(err)
        }
        r.Response.Write(v)
    })
    s.Run()

ConnectTimeout:10s GET请求时,一直用的一个链接,导致后面的请求超时被断掉了。 请求参考最新的官方代码

package main

import (
    "fmt"
    "github.com/gogf/gf/database/gredis"
    "github.com/gogf/gf/util/gconv"
)

var (
    config = gredis.Config{
        Host : "127.0.0.1",
        Port : 6379,
        Db   : 1,
    }
)

func main() {
    group := "test"
    gredis.SetConfig(&config, group)

    redis := gredis.Instance(group)
    defer redis.Close()

    _, err := redis.Do("SET", "k", "v")
    if err != nil {
        panic(err)
    }

    r, err := redis.Do("GET", "k")
    if err != nil {
        panic(err)
    }
    fmt.Println(gconv.String(r))
}

试了你这种,一压就卡住,你可以用wrk压一下试试

[root@centos7 bin]#./wrk -c5000 -d10 -t4 -T3 --latencyv http://10.11.81.174:9999

所以我要放在http服务调用,应该怎么写?我也是参照了这个例子放在一个http服务里面调用就不行了

没有conn的 在Do会默认调用close方法进行关闭

目前没有定位到什么原因

建议使用新版的V2.1.2版本
