如何覆盖供应商类文件? [英] How to override vendor class file?

问题描述

我的laravel版本:5.2

My laravel version : 5.2

我想覆盖tymondesigns/jwt-auth GetUserFromToken.php

I want to override tymondesigns/jwt-auth GetUserFromToken.php

\vendor\tymon\jwt-auth\src\Middleware\GetUserFromToken.php

    class GetUserFromToken extends BaseMiddleware
    {
        /**
         * Handle an incoming request.
         *
         * @param  \Illuminate\Http\Request  $request
         * @param  \Closure  $next
         * @return mixed
         */
        public function handle($request, \Closure $next)
        {
            if (! $token = $this->auth->setRequest($request)->getToken()) {

                return $this->respond('tymon.jwt.absent', 'token_not_provided', 400);
            }

例如，我想在不提供令牌的情况下返回自定义消息.

For example, I want to return a custom message when token is not provided.

if (! $token = $this->auth->setRequest($request)->getToken()) {

            return my_custom_message;
        }

由于我不能直接在此文件上进行更改，因此我应该如何创建一个自定义类以覆盖供应商的GetUserFromToken.php?

since I cannot make changes directly on this file, how should I create a custom class to override vendor's GetUserFromToken.php ?

请尽可能详细描述所需的步骤.谢谢.

Please describe required steps in detail if possible. Thanks.

update#2

Kernel.php

Kernel.php

protected $routeMiddleware = [

    'jwt.auth' => \App\Http\override\MyGetUserFromToken::class,

我在下面的目录中创建了GetUserFromToken.php. myProject \ app \ Http \ override \ MyGetUserFromToken.php

I created GetUserFromToken.php in below directory. myProject\app\Http\override\MyGetUserFromToken.php

<?php

namespace App\Services\Middleware;
use Tymon\JWTAuth\Middleware\GetUserFromToken;

class MyGetUserFromToken extends GetUserFromToken
{
    public function handle($request, \Closure $next)
    {
        if (! $token = $this->auth->setRequest($request)->getToken()) {
            return my_custom_message;
        }

推荐答案

由于它只是中间件，因此您应该可以扩展此类:

Since it is simply a middleware, you should just be able to extend this class:

class MyGetUserFromToken extends GetUserFromToken 

并将此类在Kernel.php中列出作为中间件.像这样:

and list this class in Kernel.php as middleware. Like this:

'jwt.auth' => App\MyGetUserFromToken::class
