我正在创建GoLang应用程序,客户端是android手机。我能够处理连接。如果用户关闭,则使用EOF
我的问题是,如果客户端仅关闭wifi网络连接,则该连接仍然有效。
这是我的代码
func main() {
fmt.Println("Starting server...")
connection, err := net.Listen("tcp", ":4406")
if err != nil {
fmt.Println(err)
}
defer connection.Close()
manager := ClientManager{
clients: make(map[*Client]bool),
broadcast: make(chan []byte),
register: make(chan *Client),
}
go manager.start()
for {
connection, _ := connection.Accept()
if err != nil {
fmt.Println(err)
}
client := &Client{socket: connection, data: make(chan []byte), uuid: connection.RemoteAddr().String()}
manager.register <- client
go manager.receive(client)
go handleConnection(client)
}
}
处理连接
func handleConnection(client *Client) {
conn := client.socket
defer conn.Close()
notify := make(chan error)
go func() {
buf := make([]byte, 1024)
for {
n, err := conn.Read(buf)
if err != nil {
notify <- err
return
}
if n > 0 {
fmt.Println("unexpected data: %s", buf[:n])
}
}
}()
for {
select {
case err := <-notify:
if err != nil {
fmt.Println("connection dropped message", err)
return
}
case <-time.After(time.Second * 1):
fmt.Println("timeout 1, still alive")
}
}
}
关闭远程wifi(拔下电缆)后,我想断开用户连接。我试图读取一个字节,然后每秒读取一次。我发送了一个字节,它也被发送了。
