Laravel 错误未传递给视图

Question

我不明白为什么 laravel Blade 没有捕捉到我的错误验证并且没有将它传递给我的视图。 详细的

• 我的刀片模板中有错误 sn-p
• 下面是我的验证，它可以正常工作

我错过了什么？

谢谢

这是我看到的 json 消息，而不是刀片模板中的消息

{ message: "给定的数据无效。", 状态码：500 }

我用这个 sn-p 让用户知道错误

@if(count($errors))
<div class="form-group">
    <div class="alert alert-danger">
        <ul>
            @if($errors->all())
                @foreach($errors->all() as $error)
                    <li>{{$error}}</li>
                @endforeach
            @endif
        </ul>
    </div>
</div> @endif

最后这是我正确工作的验证

        $request->validate([
        'email' => 'required|email|unique:subscribers|max:255',
    ]);

编辑：

这是web.php中的溃败

Route::post('saveemail', 'SaveSubscriberEmailController@saveEmail');

这就是方法

namespace App\Http\Controllers;


use App\subscriber;

use Carbon\Carbon;

use Illuminate\Http\Request;

use Ramsey\Uuid\Uuid;


class SaveSubscriberEmailController extends Controller
{

    public function saveEmail(Request $request)
    {
        $request->validate([
            'email' => 'required|email|unique:subscribers|max:255',
        ]);



        $uuid = Uuid::uuid4();

        $subscriber = new subscriber();
        $subscriber->email = $request->email;
        $subscriber->uuid = $uuid->toString();
        $subscriber->created_at = Carbon::now();
        $subscriber->save();

        flash('Registration conformation email has been sent. Please check your mailbox. Thank you!')->success();
        return redirect()->back();
    }
}

Answer 1

我以前遇到过这个问题，我能够解决的方法是使用包含中间件 \Illuminate\View\Middleware\ShareErrorsFromSession::class 的中间件组来包装路由。它将会话的错误添加到视图中。

在您的 Kernel.php 类的 protected $middlewareGroups 数组中，它可能类似于：

'web' => [
    \Illuminate\View\Middleware\ShareErrorsFromSession::class,
    // other middleware
],

然后你可以在哪里声明你的路线：

Route::group(['middleware' => ['web']], function () { 
    Route::post('saveemail', 'SaveSubscriberEmailController@saveEmail'); 
};

Answer 2

请求验证仅发送错误 422 而不是 500 如果您收到此错误，那是因为其他原因，formRequest 错误包不会捕获此错误。

Answer 3

Route::post('saveemail', 'SaveSubscriberEmailController@saveEmail');

将此路由放入web中间件。你可以这样做

Route::middleware(['web'])->group(function () {

   Route::post('saveemail', 'SaveSubscriberEmailController@saveEmail');

});

把你的控制器改成这个。

class SaveSubscriberEmailController extends Controller
{

public function saveEmail(Request $request)
{



    $validator = validate($request->all(),[
        'email' => 'required|email|unique:subscribers|max:255',
    ]);

   if($validator->fails()){
    return back()->withErrors($validator);
 }



    $uuid = Uuid::uuid4();

    $subscriber = new subscriber();
    $subscriber->email = $request->email;
    $subscriber->uuid = $uuid->toString();
    $subscriber->created_at = Carbon::now();
    $subscriber->save();

    flash('Registration conformation email has been sent. Please check your mailbox. Thank you!')->success();
    return redirect()->back();
}

}

希望对你有帮助
