Question

我正在开发客户端门户应用程序。 Laravel-5.8是后端，而Angular-7是前端。我有这张桌子：

表

CREATE TABLE `client_quotes` (
  `id` bigint(20) UNSIGNED NOT NULL,
  `first_name` varchar(255) COLLATE utf8mb4_unicode_ci NOT NULL,
  `last_name` varchar(255) COLLATE utf8mb4_unicode_ci NOT NULL,
  `email` varchar(255) COLLATE utf8mb4_unicode_ci NOT NULL,
  `phone` varchar(255) COLLATE utf8mb4_unicode_ci NOT NULL,
  `address` varchar(255) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
  `business_name` varchar(255) COLLATE utf8mb4_unicode_ci NOT NULL,
  `truck_required` int(10) UNSIGNED NOT NULL,
  `truck_type` varchar(255) COLLATE utf8mb4_unicode_ci DEFAULT 'Flatbed 20 Ton',
  `quote_origin` varchar(255) COLLATE utf8mb4_unicode_ci NOT NULL,
  `quote_destination` varchar(255) COLLATE utf8mb4_unicode_ci NOT NULL,
  `commodity` varchar(255) COLLATE utf8mb4_unicode_ci NOT NULL,
  `loading_date` datetime DEFAULT NULL,
  `comment` varchar(255) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;

ApiController.php

    public function createClientQuote(Request $request) {
        $request->validate([
                    'first_name' => 'required',
                    'last_name' => 'required',
                    'email' => 'required|email',
                    //'email' => 'required|email|unique:users|max:255',
                    'phone' => 'required|max:14',
                    'business_name' => 'required',
                    'truck_type' => 'required',
                    'truck_required' => 'required',
                    'quote_origin' => 'required',
                    'quote_destination' => 'required',
                    'commodity' => 'required',  
                    // 'weight' => 'required',
                    'loading_date' => 'date|required' 
        ]);
        $clientquote = new ClientQuote;
        $clientquote->first_name=$request->get('first_name');
        $clientquote->last_name=$request->get('last_name');
        $clientquote->email=$request->get('email');
        $clientquote->phone=$request->get('phone');
        $clientquote->business_name=$request->get('business_name');
        $clientquote->truck_type=$request->get('truck_type');
        $clientquote->truck_required=$request->get('truck_required');
        $clientquote->quote_origin=$request->get('quote_origin');
        $clientquote->quote_destination=$request->get('quote_destination');
        $clientquote->commodity=$request->get('commodity');
        $loading_date=date_create($request->get('loading_date'));
        $format = date_format($loading_date,"Y-m-d H:i:s");
        $clientquote->loading_date = strtotime($format);
        $clientquote->save();

        return response()->json([
            'message' => 'Quote Successfully Sent!'
        ], 201);
    }

在上面的ApiController.php中，我尝试使用以下格式设置loading_date：

    $loading_date=date_create($request->get('loading_date'));
    $format = date_format($loading_date,"Y-m-d H:i:s");
    $clientquote->loading_date = strtotime($format);

client-quote.component.html

    <form class="form-clientquote" #clientquoteForm=ngForm (ngSubmit)="onSubmit()">
    <div class="row">
      <div class="col-xs-12">

        <div class="col-xs-6">
        <label for="loading_date">Loading Date<span style="color:red;"> *</span></label>
        <div class="input-group date" style="width: 100%;" >
        <mat-form-field>
        <input matInput [matDatepicker] = "picker" placeholder = "Choose a date" name="loading_date" [ngModel]="form.loading_date | date: 'dd/MM/yyyy'" (ngModelChange)=" form.loading_date= $event"  #loading_date="ngModel" [ngClass]="{'is-invalid' : loading_date.invalid && ((loading_date.dirty || loading_date.touched) || clientquoteForm.submitted)}"   required>
          <mat-datepicker-toggle matSuffix [for] = "picker"></mat-datepicker-toggle>
           <mat-datepicker #picker></mat-datepicker>
           </mat-form-field>
           <div class="form-feedback" *ngIf="loading_date.invalid && ((loading_date.dirty || loading_date.touched) || clientquoteForm.submitted)">
              <div style="color:red;" *ngIf="loading_date.errors?.required"class="alert alert-danger">Loading Date is required.</div>
              </div>
           </div>
         </div>
     </div>
   </div>

   <div class="row">
     <div class="col-xs-12">
       <div class="col-xs-12">
       <div class="btn-group">
          <button style="margin:5px" (keyup.enter)="onSubmit()" type="submit" class="btn btn-success" awNextStep> Get A Quote</button>
       </div>
       </div>
     </div>
   </div>
   </form>

当我单击提交按钮时，我希望该应用程序保存到数据库中。我收到此错误：

“ SQLSTATE [22007]：无效的日期时间格式：1292错误的日期时间值：第1行的列clientportal。client_quotes。loading_date的'1572307200'（SQL：插入{{ 1}}（client_quotes，first_name，last_name，email，phone，business_name，truck_type，{{1} }，truck_required，quote_origin，quote_destination，commodity，loading_date）值（Ademola，Adebila，decking @ gmail.com，09004814390，JOKA，I Don不知道，2，Ajegunle，Ebutt，Rice，1572307200，2019-10-02 11:15:42，2019-10-02 11:15:42））“

我认为该错误与loading_date有关。我该如何解决？

Answer 1

一个connection made: 1 sockets connected disconncted made: 0 sockets connected zUEZDSmfVdJnfwriAAAA disconnected C:\Users\La Fam\desktop\project\server.js:40 if (err) throw err; ^ Error: EPERM: operation not permitted, unlink 'C:\Users\La Fam\desktop\project\u serdatax\zUEZDSmfVdJnfwriAAAA'列需要一个datetime格式的值。但是您正在尝试插入Y-m-d H:i:s之类的UNIX时间戳。因此这导致了问题。如果要使用UNIX时间戳记，请使列类型为1572307200或保持其不变。您可以稍后将其转换为UNIX时间戳。因此，现在删除varchar函数。

Answer 2

看着错误代码，看来loading_date属性的值是unix纪元的字符串表示形式，而不是日期时间对象。

作为修复，我建议您迁移SQL loading_date列以使用字符串值，然后将fe请求值转换为ISO dateTimeString。稍后，如果您需要使用dateTime / / Carbon对象的本机方法，则很容易将db中的字符串解析为dateTime / / Carbon对象。

这样做的另一个好处是，您还可以存储时间本地化数据，而不必担心将来对库的更改会破坏代码。
