参数类型不能分配给类型的参数

假设 devices 是一个对象数组,我认为您不能在那里分配您的函数,因为函数只需要一个参数就可以获得单个设备。尝试:

  const db = admin.firestore()
  const devicesRef = db.collection('devices')
  const result = await devicesRef.get();

  // adds all results to devices list
  List<any> devices = [];
  for (QueryDocumentSnapshot device : result.getResult()) {
    devices.add(device);
  }

  devices.forEach((device idx, array) => {
    if (idx === array.length -1) {
       // Do specific task
    }
    // some async function
    async (someOtherFunction) => {
       // do something with individual device
    }
});
