【问题描述】：
我一直在为我的系统开发生物特征解析模块我已经实现了将原始数据从生物特征单元读取到数据库中的目标。我的问题是，每当我系统中的用户上传原始生物特征文件时，服务器在处理上传和读取时不会提供任何页面或请求。我想有一些指点，并学习一些更好地处理这个过程的原则
来自单位的生物特征文件如下所示
129 2019-06-23 18:13:10 1 0 0 0
98 2019-06-23 18:51:46 1 0 0 0
101 2019-06-23 19:07:29 1 1 0 0
103 2019-06-23 19:07:37 1 1 0 0
85 2019-06-23 21:14:01 1 1 0 0
132 2019-06-23 23:48:54 1 1 0 0
203 2019-06-24 03:45:44 1 0 0 0
138 2019-06-24 04:10:06 1 0 0 0
204 2019-06-24 05:12:57 1 0 0 0
157 2019-06-24 05:58:07 1 0 0 0
该文件有 1,700 多行，每行是一个生物特征记录
在我的控制器中有这个来评估每一行并将其存储在数据库中 声明了一个生物特征批次，以跟踪正在上传的生物特征数据
public function store(Request $request)
{
if(Auth::check()){
$repeatedRecords =0;
// evaluate if the file is recieved
set_time_limit(360);
if($request->hasFile('BiometricDataFile')){
$biometricDataLogFile = file($request->BiometricDataFile);
foreach($biometricDataLogFile as $logFile){
$BiometricDBRecord = new Biometric;
$biometricRecord = explode("\t", $logFile);
$BiometricDBRecord->employee_id = $biometricRecord[0];
$BiometricDBRecord->location = $request->location;
$BiometricDBRecord->logDate = Carbon::parse($biometricRecord[1]);
$date = explode(' ', $biometricRecord[1]);
$BiometricDBRecord->bioDate = $date[0];
$BiometricDBRecord->bioTime = $date[1];
$BiometricDBRecord->uploaded_by = Auth::user()->employee_id;
if(Biometric::where('logDate','=', $biometricRecord[1])->count() <= 0){
$BiometricDBRecord->save();
}else{
$repeatedRecords++;
}
}
$newBatch = new BiometricBatch();
//Setting up data for return to view
$timeNow = Carbon::now('GMT+8')->toDateTimeString();
$thirtyMinEarlier = Carbon::now('GMT+8')->subHours(12)->toDateTimeString();
$biometricDataSaved = Biometric::whereBetween('created_at', [$thirtyMinEarlier, $timeNow])->where('uploaded_by', Auth::user()->employee_id)->get();
$biometricDataSaved->sortBy('logDate');
$sortedFirst = $biometricDataSaved->first();
$sortedLast = $biometricDataSaved->last();
$newBatch->employee_id = Auth::user()->employee->id;
$newBatch->batch_upload_date = Carbon::now();
$newBatch->batch_start_date = $sortedFirst->logDate;
$newBatch->batch_end_date = $sortedLast->logDate;
$newBatch->isProcessed = false;
$newBatch->save();
}else{ //if the file is not recieved
return "<h1> File not found </h1>";
}
$activityLog = new ActivityLog();
$activityLog->employee_id = Auth::user()->employee_id;
$activityLog->action = 'Has uploaded biometric data';
$activityLog->save();
return view('pages.employeeBiometric')->with('savedLogs', $biometricDataSaved, 'duplicates', $repeatedRecords);
}else{
return view('errors.401');
}
}
我有一种直觉，我可能应该在 javascript 或 ajax 中执行此操作，但不知道从哪里开始以及如何执行。我想学习如何更好地实现它并从我的错误中学习，谢谢你有一个很棒的天。
