Question

let filePath = "uploaded image url"
var fileSize : UInt64
do {

  let attr = try FileManager.default.attributesOfItem(atPath: (filePath?.path)!)
  fileSize = attr[FileAttributeKey.size] as! UInt64
  print(fileSize)

  let fileSizeWithUnit = ByteCountFormatter.string(fromByteCount: Int64(fileSize), countStyle: .file)
  print("File Size: \(fileSizeWithUnit)")

} catch {
  print("Error: \(error)")
}

我们在用户身份验证后经常出现上述错误，并且用户需要超过1分钟的时间才能显示在在线表格中。关于原因和解决方案有什么想法吗？

谢谢

更新：在使用的触发器下方：

public  void calc(){
 for(int i = 0; i < mSearchResultModelsToGetAppointments.size(); i++){
   Location newLocation = new Location("");
   newLocation.setLatitude(gpsTracker.getLatitude());
   newLocation.setLongitude(gpsTracker.getLongitude());
   if(String.valueOf(gpsTracker.getLatitude()).equalsIgnoreCase("0.0") || String.valueOf(gpsTracker.getLongitude()).equalsIgnoreCase("0.0")) {
    } else{
        Location oldLocation = new Location("");              
        oldLocation.setLatitude(mSearchResultModelUnderProcess.getLatitude());
        oldLocation.setLongitude(mSearchResultModelUnderProcess.getLongitude());   
        float distanceInMeters = newLocation.distanceTo(oldLocation)/1000;           
        if(distanceInMeters < 2820){
            getAdapter().notifyDataSetChanged();
            getAdapter().removeItem(i);
            getAdapter().notifyDataSetChanged();
        }
    }
 }
}

UPDATE2：我们创建了2个触发器。一个在INSERT上，另一个在UPDATE上。

在radacct上插入后：

Error: [sql] Couldn't insert SQL accounting START record - Can't update table 'useraccounting' in stored function/trigger because it is already used by statement which invoked this stored function/trigger

在radacct上更新后：

    CREATE DEFINER=`mysql`@`%` TRIGGER `radacct_after_update` AFTER UPDATE ON `radacct` FOR EACH ROW BEGIN
  if (NEW.acctoutputoctets != OLD.acctoutputoctets)
  THEN
    UPDATE useraccounting SET tmpQuta = tmpQuta + (New.acctoutputoctets - OLD.acctoutputoctets)
    WHERE EXISTS (SELECT * FROM users WHERE users.userable_id = useraccounting.client_id AND users.userable_type = 'App\\Models\\Client' AND (users.username = New.username));
  END IF;
END
