android使用OkHttp发送websocket请求代码

以下是Android使用OkHttp发送WebSocket请求的示例代码：

import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;
import okhttp3.WebSocket;
import okhttp3.WebSocketListener;
import okio.ByteString;

public class WebSocketClient extends WebSocketListener {

    private OkHttpClient client;
    private WebSocket webSocket;

    public WebSocketClient() {
        client = new OkHttpClient();
    }

    public void start() {
        Request request = new Request.Builder().url("wss://your.websocket.url").build();
        webSocket = client.newWebSocket(request, this);
    }

    @Override
    public void onOpen(WebSocket webSocket, Response response) {
        super.onOpen(webSocket, response);
        // 连接成功
        webSocket.send("Hello, WebSocket!");
    }

    @Override
    public void onMessage(WebSocket webSocket, String text) {
        super.onMessage(webSocket, text);
        // 收到消息
    }

    @Override
    public void onMessage(WebSocket webSocket, ByteString bytes) {
        super.onMessage(webSocket, bytes);
        // 收到二进制消息
    }

    @Override
    public void onClosing(WebSocket webSocket, int code, String reason) {
        super.onClosing(webSocket, code, reason);
        // 正在关闭连接
    }

    @Override
    public void onClosed(WebSocket webSocket, int code, String reason) {
        super.onClosed(webSocket, code, reason);
        // 连接已关闭
    }

    @Override
    public void onFailure(WebSocket webSocket, Throwable t, Response response) {
        super.onFailure(webSocket, t, response);
        // 连接失败
    }
}

使用方法：

WebSocketClient client = new WebSocketClient();
client.start();

注意：需要在AndroidManifest.xml中添加网络权限：

<uses-permission android:name="android.permission.INTERNET" />
