appHttpProvidersRouteServiceProvider.php 中 mapRoute 取消强制给加上的web中间件调用。自己在自己的路由中需要的时候增加 middleware=>web That’s it

Try not to modify itapp/Http/Kernel.php，极不推荐关闭CSRF。
修改app/Http/Middleware/VerifyCsrfToken.php to exclude the specified URL from CSRF verification.

<?php

    namespace App\Http\Middleware;

    use Illuminate\Foundation\Http\Middleware\VerifyCsrfToken as BaseVerifier;

    class VerifyCsrfToken extends BaseVerifier
    {
        /**
         * 指定从 CSRF 验证中排除的URL
         *
         * @var array
         */
        protected $except = [
            'testCsrf'
        ];
    }

/app/Http/Kernel.php第31行AppHttpMiddlewareVerifyCsrfToken::class,Delete or comment

It would be better if you take your routing out of the web middleware group.
