Java 使用连接apache paho websocket客户端发送查询参数

我有一个连接到代理的mqtt客户机。 我的代理拦截连接以从中获取令牌并执行一些工作。 我想在连接时发送一个令牌作为查询参数

        MqttAsyncClient sampleClient = new MqttAsyncClient(broker, clientId, persistence);
        MqttConnectOptions connOpts = new MqttConnectOptions();

        connOpts.setCleanSession(false);

        connOpts.setAutomaticReconnect(true);
        connOpts.setKeepAliveInterval(MqttConnectOptions.KEEP_ALIVE_INTERVAL_DEFAULT);

        connOpts.setConnectionTimeout(MqttConnectOptions.CONNECTION_TIMEOUT_DEFAULT); 
        IMqttToken token = sampleClient.connect(connOpts);

我的客户是这样连接的：

        MqttAsyncClient sampleClient = new MqttAsyncClient(broker, clientId, persistence);
        MqttConnectOptions connOpts = new MqttConnectOptions();

        connOpts.setCleanSession(false);

        connOpts.setAutomaticReconnect(true);
        connOpts.setKeepAliveInterval(MqttConnectOptions.KEEP_ALIVE_INTERVAL_DEFAULT);

        connOpts.setConnectionTimeout(MqttConnectOptions.CONNECTION_TIMEOUT_DEFAULT); 
        IMqttToken token = sampleClient.connect(connOpts);

我该怎么做？有人能帮我吗？

如果您修改类中的方法

sendHandshakeRequest

，这可能是可能的：

        MqttAsyncClient sampleClient = new MqttAsyncClient(broker, clientId, persistence);
        MqttConnectOptions connOpts = new MqttConnectOptions();

        connOpts.setCleanSession(false);

        connOpts.setAutomaticReconnect(true);
        connOpts.setKeepAliveInterval(MqttConnectOptions.KEEP_ALIVE_INTERVAL_DEFAULT);

        connOpts.setConnectionTimeout(MqttConnectOptions.CONNECTION_TIMEOUT_DEFAULT); 
        IMqttToken token = sampleClient.connect(connOpts);

由于该方法是

private

，并且该类位于

internal

包中，因此您别无选择，只能编译您自己的自定义版本的Paho库

        MqttAsyncClient sampleClient = new MqttAsyncClient(broker, clientId, persistence);
        MqttConnectOptions connOpts = new MqttConnectOptions();

        connOpts.setCleanSession(false);

        connOpts.setAutomaticReconnect(true);
        connOpts.setKeepAliveInterval(MqttConnectOptions.KEEP_ALIVE_INTERVAL_DEFAULT);

        connOpts.setConnectionTimeout(MqttConnectOptions.CONNECTION_TIMEOUT_DEFAULT); 
        IMqttToken token = sampleClient.connect(connOpts);
