A 419 error occurred in the laravel postman submission form. July 6th, 2020 diary.

Studying recently laraveel introduction , Learned the upload and download section , Because I haven't learned about controllers and views yet , So just use it. postman Mock submit form , Uploaded a small file .
But with postman When submitting forms and uploading files , appear 了 419 error , This is because csrf The limitation of . The result of Baidu solution is probably 3 individual

The first is to annotate the middleware ：
app\Http\Kernel.php

    protected $middlewareGroups = [
        'web' => [
            \App\Http\Middleware\EncryptCookies::class,
            \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
            \Illuminate\Session\Middleware\StartSession::class,
            // \Illuminate\Session\Middleware\AuthenticateSession::class,
            \Illuminate\View\Middleware\ShareErrorsFromSession::class,
          
          // Comment out the following line 
          // \App\Http\Middleware\VerifyCsrfToken::class,
          
            \Illuminate\Routing\Middleware\SubstituteBindings::class,
        ],

        'api' => [
            'throttle:60,1',
            \Illuminate\Routing\Middleware\SubstituteBindings::class,
        ],
    ];

The second way is Set the whitelist
app\Http\Middleware\VerifyCsrfToken.php

<?php

namespace App\Http\Middleware;

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

class VerifyCsrfToken extends Middleware
{
    
    /** * The URIs that should be excluded from CSRF verification. * * @var array */
    protected $except = [
        // Set... Here  *
        '*'
    ];
}

this 2 It's true that the function can be realized in three steps , But this 2 All of them are extreme , So I tried to set the white list for a certain method of a certain controller , It is written as follows

<?php

namespace App\Http\Middleware;

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

class VerifyCsrfToken extends Middleware
{
    
    /** * The URIs that should be excluded from CSRF verification. * * @var array */
    protected $except = [
        // Set... Here  *
        // '*'
        '[email protected]',
        'index/index',
        'www.blog.com/scc'

    ];



}

Tried three ways to write All wrong , use postman Upload file or 419 error , Later, the real solution was found .

<?php

namespace App\Http\Middleware;

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

class VerifyCsrfToken extends Middleware
{
    
    /** * The URIs that should be excluded from CSRF verification. * * @var array */
    protected $except = [
		# This is the way the root is written in Miao Hong .
        'scc'
    ];
}

scc Is the routing ID .
as follows

# Routing rules 
Route::any('scc', '[email protected]');

# Method of controller 

    function scc(Request $request){
    
// echo csrf_token();

        $name = $request->file('filename');
        echo '<pre>';
        print_r($name->path());
        echo '</pre>';
        echo '<hr>';
        die;
    }
