以下是使用 OkHttp Android WebSocket 框架发送 WebSocket 消息的示例代码:
```java
public class WebSocketClient {
private WebSocket webSocket;
public void connectWebSocket() {
OkHttpClient client = new OkHttpClient();
Request request = new Request.Builder()
.url("ws://your-websocket-url.com")
.build();
WebSocketListener listener = new WebSocketListener() {
@Override
public void onOpen(WebSocket webSocket, Response response) {
super.onOpen(webSocket, response);
// WebSocket连接成功
WebSocketClient.this.webSocket = webSocket;
}
@Override
public void onMessage(WebSocket webSocket, String text) {
super.onMessage(webSocket, text);
// 接收到WebSocket消息
}
@Override
public void onClosed(WebSocket webSocket, int code, String reason) {
super.onClosed(webSocket, code, reason);
// WebSocket连接关闭
}
@Override
public void onFailure(WebSocket webSocket, Throwable t, Response response) {
super.onFailure(webSocket, t, response);
// WebSocket连接失败
}
};
webSocket = client.newWebSocket(request, listener);
}
public void sendMessage(String message) {
if (webSocket != null) {
webSocket.send(message);
}
}
}
```
在上述代码中,首先使用 OkHttpClient 创建 WebSocket 连接,并指定 WebSocket 连接的 URL。然后,实现 WebSocketListener,通过重写 onOpen、onMessage、onClosed 和 onFailure 方法处理 WebSocket 连接的生命周期和消息接收。
在 sendMessage 方法中,如果 WebSocket 已连接,则可以通过 webSocket 发送消息。
