我正在尝试运行 socketcluster-android-client 演示应用程序 (https://github.com/sacOO7/socketcluster-android-demo)。我的服务器在 localhost:8000 成功运行。我正在从我的手机连接到:ws://localhost:8000/socketcluster/
。
当我尝试运行应用程序时,连接失败并出现错误:
Got connect error com.neovisionaries.ws.client.WebSocketException: Failed to connect to 'localhost:8000': failed to connect to localhost/127.0.0.1 (port 8000) from /127.0.0.1 (port 42405) after 5000ms: isConnected failed: ECONNREFUSED (Connection refused)
我已经验证了以下内容(来自其他 SO 答案):
- 防火墙访问权限
- 成功远程登录到 localhost:8000
- 正在运行的服务器和我的手机在同一个wifi网络上的PC
- 升级到最新的 Node 版本
这是尝试连接到套接字的代码:
socket = new Socket(url);
socket.setListener(new BasicListener() {
public void onConnected(Socket socket, Map<String, List<String>> headers) {
socket.createChannel("MyClassroom").subscribe(new Ack() {
@Override
public void call(String name, Object error, Object data) {
if (error==null){
Log.i ("Success","subscribed to channel "+name);
}
}
});
Log.i("Success ","Connected to endpoint");
}
public void onDisconnected(Socket socket, WebSocketFrame serverCloseFrame, WebSocketFrame clientCloseFrame, boolean closedByServer) {
Log.i("Success ","Disconnected from end-point");
}
public void onConnectError(Socket socket,WebSocketException exception) {
Log.i("Success ","Got connect error "+ exception);
}
public void onSetAuthToken(String token, Socket socket) {
socket.setAuthToken(token);
}
public void onAuthentication(Socket socket,Boolean status) {
if (status) {
Log.i("Success ","socket is authenticated");
} else {
Log.i("Success ","Authentication is required (optional)");
}
}
});
socket.setReconnection(new ReconnectStrategy().setMaxAttempts(10).setDelay(3000));
socket.connectAsync();
最佳答案
我必须在 URL 中使用 PC 的 IP 地址。已替换 ws://localhost:8000/socketcluster/
与 ws://<PC's IP address>:8000/socketcluster/
.
