HarmonyOS从9升级到11后 http和mqtt 都报错 无法编译了

import { MqttAsync,MqttClient, MqttQos, MqttSubscribeOptions } from '@ohos/mqtt' 
export class MyMqttClient { 
  private mqttClient : MqttClient ; 
  提示: 
    Property 'mqttClient' has no initializer and is not definitely assigned in the constructor. <ArkTSCheck> 
  await response.then((data) => { 
  const code = data.responseCode 
  if (code == 200) { 
  console.info('http code:' + code); 
  responsedata = JSON.parse(data.result.toString()); 
  const userPhone = responsedata .data.user.user_phone; 
  const username = responsedata .data.mqtt.username; 
  const token = responsedata .data.token; 
  console.log("http user_phone:", userPhone); 
  console.log("http username:", username); 
  console.log("http token:", token); 
}else{ 
  console.info('http code!:' + code+" "+data.result.toString()); 
  console.info("http token:", token); 
} 
}).catch((err:string) => { 
  console.info('error:' + JSON.stringify(err)); 
}) 
提示: 
  Use explicit types instead of "any", "unknown" (ArkTS-no-any-unknown) <ArkTSCheck>
