Websocket.disconnect()方法抛出java.net.SocketException:套接字已关闭 [英] Websocket.disconnect() method throws java.net.SocketException: Socket closed
问题描述
我在我的项目中使用了来自Codebutler的android-websockets库.但是当我执行 disconnect()方法时遇到了问题.以下是代码:
I am using android-websockets library from codebutler in my project. But I ran into problem when I execute disconnect() method. Following is the code:
public void disconnectServer()
{
if(client != null)
{
try {
if(client.isConnected())
{
client.disconnect();
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
我得到以下异常:

请帮助！！！！！
推荐答案
这是因为connect()方法的实现与connect()方法的实现中创建的线程不同步. codebutler/android-websockets 不具有商业品质.Disconnect()方法甚至无法执行关闭握手通过 RFC 6455 .
It is because the implementation of disconnect() method does not synchronize with the thread which is created in the implementation of connect() method. codebutler/android-websockets is not of commercial quality. The disconnect() method does not perform even the closing handshake which is required by RFC 6455.
如果不想看到错误，请使用另一个WebSocket库.
Use another WebSocket library if you don't want to see the error.
