无法在android中连接websocket和wss

Question

我正在尝试使用org.java_websocket.client.WebSocketClient API在android中连接安全websocket连接wss://,但无法与https连接.但是它与ws://一起工作正常.这是我的代码.

private void connect(String websocketEndPointUrl) throws Exception {
    URI uri;
    try {

        websocketEndPointUrl="wss://echo.websocket.org:443";
        Log.i(TAG, " WSURL: " + websocketEndPointUrl);

        uri = new URI(websocketEndPointUrl);
    } catch (URISyntaxException e) {
        Log.e(TAG, e.getMessage());
        return;
    }

    mWebSocketClient = new WebSocketClient(uri,new Draft_17()) {
        @Override
        public void onOpen(ServerHandshake serverHandshake) {
            Log.i("Websocket", "Opened");
         }

        @Override
        public void onMessage(String s) {
            //final String message =s;

         }

        @Override
        public void onClose(int i, String s, boolean b) {
            Log.i("Websocket", "Closed " + s);
         }

        @Override
        public void onError(Exception e) {
            Log.i("Websocket", "Error " + e.getMessage());
         }
    };
    mWebSocketClient.connect();
}

我正在使用在线测试websocket url:ws://echo.websocket.org(端口80)//使用wss://echo.websocket.org(端口443)根据我的观察,不需要证书在我的代码中.任何人都可以建议我是什么原因以及我如何解决这个问题.

找到解决方案.我不知道为什么这不是文档的一部分.您只需要在WebSocketClient初始化之后和方法之前设置setWebSocketFactory.connect()

mWebSocketClient = new WebSocketClient(uri,new Draft_17()) 
{
    @Override
    public void onOpen(ServerHandshake serverHandshake) {
        Log.i("Websocket", "Opened");
    }

    @Override
    public void onMessage(String s) {
        //final String message =s;

    }

    @Override
    public void onClose(int i, String s, boolean b) {
        Log.i("Websocket", "Closed " + s);
    }

    @Override
    public void onError(Exception e) {
        Log.i("Websocket", "Error " + e.getMessage());
    }
};

if (websocketEndPointUrl.indexOf("wss") == 0) 
{
    try {
        SSLContext sslContext = SSLContext.getDefault();
        mWebSocketClient.setWebSocketFactory(new DefaultSSLWebSocketClientFactory(sslContext));
    } catch (NoSuchAlgorithmException e) {
        e.printStackTrace();
    }
} 

mWebSocketClient.connect();
