从列表中删除客户端会杀死其他连接

为什么要杀死来自其他客户端的简单“ClientList.Remove(entry)”所有连接?


我有一个非常简单的 Go TCP Server,可以进行连接处理和登录处理。之后,如果创建一个客户端并使用 TCP 客户端启动一个 GO 程序。


newClient := &Client{"", "", login.LoginToken, conn} go ClientReader(newClient) ClientList.PushBack(*newClient)


Go 例程读取所有传入的数据。当连接超时或网络更改(客户端获得新 IP)时,它会从客户端列表中删除客户端。


但是当它从列表中删除客户端时......所有其他客户端连接都死了?在循环中它找到正确的客户端并将其删除。


看看removeloop:


常规:


func ClientReader(client *Client) {

    buffer := make([]byte, 2048)

    for {

        bytesRead, error := client.Conn.Read(buffer)

    if error != nil {

        Log(error)

        break

    }


    var m Message

    err := json.Unmarshal([]byte(buffer[0:bytesRead]), &m)

    if err != nil {

        Log(err)

    } else {


        switch m.Cmd {

        case "Message":


        case "Ping":

            Log("Ping from: ", client.Name, " on ", client.Conn.RemoteAddr())

            client.Conn.SetDeadline(time.Now().Add(25 * time.Second))

            pong := []byte(`{"PONG":"..."}` + "\r\n")

            client.Conn.Write(pong)

            Log("PONG: " + time.Now().Format(time.RFC850))

            Log("User Online: " + strconv.Itoa(ClientList.Len()))

            Log("Goroutines: " + strconv.Itoa(runtime.NumGoroutine()))


        default:

            Log("Not supported Command: ", m.Cmd)

            clienterror := []byte(`{"Err":"Command not supported"}` + "\r\n")

            client.Conn.Write(clienterror)

        }

        for i := 0; i < 2048; i++ {

            buffer[i] = 0x00

        }

    }


}


RemoveLoop:

    for entry := ClientList.Front(); entry != nil; entry = entry.Next() {

        listclient := entry.Value.(Client)

        if client.Conn.RemoteAddr() == listclient.Conn.RemoteAddr() {

        ClientList.Remove(entry)

        Log("## SEARCH: ", client.Name, client.Conn.RemoteAddr())

        Log("## FOUND: ", listclient.Name,listclient.Conn.RemoteAddr())

    Log("## REMOVED: ", entry.Value)

    break RemoveLoop

    }

}

Log("Exit Client Reader Routine ", client.Name, " on ", client.Conn.RemoteAddr())

}
