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())
}
