HarmonyOS string.json中的字符串值怎么同步获取

let manager = getContext(this).resourceManager 
try { 
  manager.getStringValue($r('app.string.abc').id, (error, value) => { 
    if (error != null) { 
      console.log("error is " + error); 
    } else { 
      this.title = value; 
      console.log(value) 
      console.log(this.title) 
    } 
  }); 
} catch (error) { 
  console.error(`callback getStringValue failed, error code: ${error.code}, message: ${error.message}.`) 
}
