Aar0n 这个我已经引入了的，只是我调用的时候使用的是d.ts文件，在ts文件中能正常调用
class Mqtt {
private client: Paho.MQTT.Client;
private message: Paho.MQTT.Message;
private self = this;
public constructor() {
public connect(url, port, client): void {
//初始化
this.client = new Paho.MQTT.Client(url, Number(port), client);
// set callback handlers
//连接消失 收到消息
this.client.onConnectionLost = this.onConnectionLost;
this.client.onMessageArrived = this.onMessageArrived;
// connect the client
this.client.connect({ onSuccess: this.onConnect.bind(this) });
}
但是调试的时候控制台显示Client未定义。
