重新连接失败:paho mqtt使用javascript

Question

当连接丢失时，将调用函数onConnectionLost，但当连接丢失后，我如何重新连接？

这是我的代码：

const client = new Paho.MQTT.Client(host, Number(port), clientID);
client.onMessageArrived = this.onMessageArrived;
client.onConnectionLost = this.onConnectionLost;
client.connect({ 
cleanSession : false, 
onSuccess : this.onConnect, 
userName: "user",
password: "pass",
onFailure : this.onConnectionLost, 
keepAliveInterval: 30, 
reconnect : true,         // Enable automatic reconnect
reconnectInterval: 10     // Reconnect attempt interval : 10 seconds
});
onConnect = () => {
const { client } = this.state;
console.log("Connected!!!!");
this.setState({isConnected: true, error: ''});
client.subscribe(topic, qos=1);
client.subscribe(topic1, qos=1);
client.subscribe(topic2, qos=1);
};
onConnectionLost(responseObject) {
if (responseObject.errorCode !== 0) {
console.log("onConnectionLost : "+responseObject.errorMessage);
this.setState({error: 'Lost Connection', isConnected: false});
}
}

错误：未知属性，reconnectInterval。有效属性为：timeout用户名密码willMessage keepAliveInterval cleanSessionuseSSL invocationContext on成功on失败主机端口重新连接mqttVersion mqttVersion显式uris

使用重新连接参数

client.connect(
{
cleanSession : false, 
onSuccess : onConnectSuccess, 
onFailure : onFailedConnect, 
keepAliveInterval: 30, 
reconnect : true,         // Enable automatic reconnect
}
