没有阻塞额。。。直接在 go func 外层定义变量, 里层接收值就可以了，

@dishonest 看这个 issue 解释 kataras/iris/issues/463 然后，测试下 上一条回复的代码

func test(ctx context.Context) {
c := make(chan int)
fmt.Println("start")
go func(){
// 等待 10 秒
time.Sleep(time.Duration(5) * time.Second)
c <- 0
}()
<- c
fmt.Println("end")
ctx.Text("test")
}

```
func test(ctx context.Context) {
go func(){
fmt.Println("start")

// 等待 10 秒
time.Sleep(time.Duration(10) * time.Second)

fmt.Println("end")

ctx.Text("test")
}()
}

```

time.sleep 是主线程休眠，你要模拟延迟响应应该写盗 go func(){}里面

其实我更好奇你写出的阻塞代码。每个 http 请求本来就是独立的啊

@Y4ssss 赞同

添加一些 ip 到防火墙后， iptables 的规则里面没有相应 ip, iptables -L 的结果是：
DROP all -- bzq-79-178-9-254.red.bezeqint.net anywhere
DROP all -- cable-24-135-138-230.dynamic.sbb.rs anywhere
DROP all -- 105-226-148-3.east.dsl.telkomsa.net anywhere
DROP all -- host-41.238.20.42.tedata.net anywhere
DROP all -- 188.228.36.184.dynamic.altibox.net anywhere
DROP all -- 91.204.60.100.cn.zp.ua anywhere

这些都是动态 vps 吧？

@7654 不是，游戏攻略，资讯类的。。

@realpg 朋友上班业务搞的网站。。哪来的专业运维。。。 另外一个写前端 js 的懂个毛线 php （笑 cry ）

错误日志里面有很多条这个

connect() to unix:/dev/shm/php-cgi.sock failed(12: Cannot allocate memory)....

这个是内存泄露的意思么

@suckli 好多 ip 。。

这是一部分 错误日志， 当把网站打开的时候 就狂刷

@Silicon 我试试 感谢

@ershisi 抓过包了 很多 ip ， status 499. 上了 阿里云的 web 防火墙 还是不行。

@asp jx3pve.com 现在我已经把它停掉了
