Laravel 5.6 CORS问题 [英] Laravel 5.6 CORS issue

问题描述

我关注了这篇文章，但它仅适用于GET方法(您可以在注释中看到它).我还安装了此包装，但同样仅适用于GET方法.这是我得到的错误:

I followed this post but it only worked for GET method (as you can see it is mentioned in comments). I also installed this pakage but again it only works for GET method. This the error I get:

所请求的资源上没有"Access-Control-Allow-Origin"标头.因此，不允许访问 我的起源 .响应的HTTP状态码为403.

No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin my origin is therefore not allowed access. The response had HTTP status code 403.

PHP版本:7.1

PHP version: 7.1

Laravel版本:5.6

前端应用程序:角度应用程序(我需要在这里更改吗?)

Frontend application: angular app (Do I need to change sth here?)

//Cours.php (middleware I created myself using the first method)
class Cors
{
    public function handle($request, Closure $next)
    {
        return $next($request)
            ->header('Access-Control-Allow-Origin', '*')
            ->header('Access-Control-Allow-Methods', 'GET, POST, PUT,         
DELETE, OPTIONS');
    }
}


//cors.php (config/cors.php second method using the laravel-cors package)
return [

    'supportsCredentials' => false,
    'allowedOrigins' => ['*'],
    'allowedOriginsPatterns' => [],
    'allowedHeaders' => ['*'],
    'allowedMethods' => ['*'],
    'exposedHeaders' => [],
    'maxAge' => 0,
];


//kernel.php
namespace App\Http;

use Illuminate\Foundation\Http\Kernel as HttpKernel;

class Kernel extends HttpKernel
{

protected $middleware = [
    \Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class,
    \Illuminate\Foundation\Http\Middleware\ValidatePostSize::class,
    \App\Http\Middleware\TrimStrings::class,
    \Illuminate\Foundation\Http\Middleware\ConvertEmptyStringsToNull::class,
    \App\Http\Middleware\TrustProxies::class,
    \Barryvdh\Cors\HandleCors::class,
];

protected $middlewareGroups = [
    'web' => [
        \App\Http\Middleware\EncryptCookies::class,
        \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
        \Illuminate\Session\Middleware\StartSession::class,
        // \Illuminate\Session\Middleware\AuthenticateSession::class,

        \App\Http\Middleware\VerifyCsrfToken::class,
        \Illuminate\Routing\Middleware\SubstituteBindings::class,
    ],

    'api' => [
        'throttle:60,1',
        'bindings',
    ],
];


protected $routeMiddleware = [
    'auth' => \App\Http\Middleware\Authenticate::class,
    'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
    'bindings' => \Illuminate\Routing\Middleware\SubstituteBindings::class,
    'cache.headers' => \Illuminate\Http\Middleware\SetCacheHeaders::class,
    'can' => \Illuminate\Auth\Middleware\Authorize::class,
    'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
    'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,
    'cors' => \App\Http\Middleware\Cors::class,
];
}

推荐答案

laravel-cors不需要任何类型的包.只需创建中间件:

No need any type package for laravel-cors. Just create Middleware:

namespace App\Http\Middleware;
use Closure;
class Cors {

    public function handle($request, Closure $next) {
        $allowedOrigins = ['http://myroute.xyz', 'http://clarkconcepts.net','http://localhost'];
        $origin = isset($_SERVER['HTTP_ORIGIN']) ? $_SERVER['HTTP_ORIGIN'] : '';
        if (in_array($origin, $allowedOrigins)) {
            return $next($request)
                ->header('Access-Control-Allow-Origin', $origin)
                ->header('Access-Control-Allow-Methods', 'GET, POST, PUT, DELETE, OPTIONS')
                ->header('Access-Control-Allow-Headers',' Origin, Content-Type, Accept, Authorization, X-Request-With, cache-control,postman-token, token')
                ->header('Access-Control-Allow-Credentials',' true');
        }
        return $next($request);
    }
}

在app/Http/Kernel.php中在$ middleware部分中添加中间件:

In app/Http/Kernel.php add Middleware in $middleware section:

protected $middleware = [
    \Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class,
    \Illuminate\Foundation\Http\Middleware\ValidatePostSize::class,
    \App\Http\Middleware\TrimStrings::class,
    \Illuminate\Foundation\Http\Middleware\ConvertEmptyStringsToNull::class,
    \App\Http\Middleware\TrustProxies::class,
    \App\Http\Middleware\Cors::class, //added here
];
