Question

在我的web.php中，我有一条路线

Route::get('summary_average_fee', 'Summary@AverageFee')->middleware('CheckParams@dateLimits');

我正尝试在CheckParams类中引用dateLimits函数

我的CheckParams类，另存为Middleware文件夹中的CheckParams.php

<?php

namespace App\Http\Middleware;

use Closure;

class CheckParams
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function dateLimits($request, Closure $next)
    {
        isEmpty($request->input('startDate'), 'NO_START_DATE');
        isEmpty($request->input('endDate'), 'NO_END_DATE');

        return $next($request);
    }

    private function isEmpty($value, $error, $status)
    {
        if(empty($value))
        {
            return response()->json($error, 422);
        }
    }
}

在kernal.php文件中，将其添加到routeMiddleware数组

'CheckParams' => \App\Http\Middleware\CheckParams::class

当它运行时，我收到错误，提示Class CheckParams @ dateLimits不存在

在我看来，您的中间件应该重写并更新用法：

use App\Http\Middleware\CheckParams;

Route::get('summary_average_fee', 'Summary@AverageFee')->middleware(CheckParams::class);

中间件：

namespace App\Http\Middleware;

use Closure;

class CheckParams
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        $this->isEmpty($request->input('startDate'), 'NO_START_DATE');
        $this->isEmpty($request->input('endDate'), 'NO_END_DATE');

        return $next($request);
    }

    private function isEmpty($value, $error, $status)
    {
        if(empty($value))
        {
            return response()->json($error, 422);
        }
    }
}

中间件功能不存在
