HarmonyOS ArkTS如何不使用await/async把异步方法改为同步方法?

checkDataInfo(brokerBridge): string { 
   const methodA = Reflect.get(brokerBridge, 'getDeviceInfoA'); 
   if (typeof methodA === 'function') { 
     let params: string | null = null; 
     const resultA = methodA.call(brokerBridge, params); 
     console.log(resultA); 
   } 
   let resultDataB = ''; 
   const methodB = Reflect.get(brokerBridge, 'getDeviceInfoB'); 
   if (typeof methodB === 'function') { 
     let params: string | null = null; 
     const resultB = methodB.call(brokerBridge, params); 
     if (Promise.resolve(resultB) === resultB) { 
       console.log('Promise对象'); 
       // 不能使用await，会让checkDataInfo变为异步 
       resultB.then((result: string) => { 
         console.log(result); 
         //todo 如何返回resultDataB值（不能将checkDataInfo方法改成异步） 
         resultDataB = result; 
       }); 
     } else { 
       console.log('非Promise对象'); 
       return resultB; 
     } 
   } 
   // 如何等待resultDataB被赋值 
   return resultDataB; 
 }
