Larval API 跨域问题解决

遇到的程序跨域问题，分享一下解决方法

这里报错

XMLHttpRequest cannot load http://*****. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8080' istherefore not allowed access.

第一步，创建中间件

在     app/Http/Middleware/   目录下创建AccessControlAllowOrigin.php，把下方完全Ctrl+c 、Ctrl+v即可

<?php

namespace AppHttpMiddleware;

use Closure;
use IlluminateSupportFacadesAuth;

class AccessControlAllowOrigin
{
    /**
     *
     * Handle an incoming request.
     *
     * @param  IlluminateHttpRequest  $request
     * @param  Closure  $next
     * @return mixed
     */

    public function handle($request, Closure $next)
    {

        header('Access-Control-Allow-Origin: *');

        header("Access-Control-Allow-Credentials: true");

        header("Access-Control-Allow-Methods: *");

        header("Access-Control-Allow-Headers: Content-Type,Access-Token");

        header("Access-Control-Expose-Headers: *");

        return $next($request);
    }
}

第二步，设置保护中间件

打开   app/Http/Kernel.php

在 protected $middleware数组中加入 AppHttpMiddlewareAccessControlAllowOrigin::class,

/**

     * The application's global HTTP middleware stack.

     *

     * These middleware are run during every request to your application.

     *

     * @var array

     */

    protected $middleware = [

        IlluminateFoundationHttpMiddlewareCheckForMaintenanceMode::class,

        IlluminateFoundationHttpMiddlewareValidatePostSize::class,

        AppHttpMiddlewareTrimStrings::class,

        IlluminateFoundationHttpMiddlewareConvertEmptyStringsToNull::class,

        AppHttpMiddlewareAccessControlAllowOrigin::class,

    ];

在  protected $middlewareGroups数组的 api 加入 你自定义路由的名称，我这里是 diyapp

    protected $middlewareGroups = [
        'web' => [
            AppHttpMiddlewareEncryptCookies::class,
            IlluminateCookieMiddlewareAddQueuedCookiesToResponse::class,
            IlluminateSessionMiddlewareStartSession::class,
            // IlluminateSessionMiddlewareAuthenticateSession::class,
            IlluminateViewMiddlewareShareErrorsFromSession::class,
            AppHttpMiddlewareVerifyCsrfToken::class,
            IlluminateRoutingMiddlewareSubstituteBindings::class,
        ],

        'api' => [
            'throttle:60,1',
            IlluminateRoutingMiddlewareSubstituteBindings::class,
            'diyapp',
        ],
    ];

在   protected $routeMiddleware 数组中加入 'diyapp' => AppHttpMiddlewareAccessControlAllowOrigin::class,

protected $routeMiddleware = [
        'auth' => AppHttpMiddlewareAuthenticate::class,
        'auth.basic' => IlluminateAuthMiddlewareAuthenticateWithBasicAuth::class,
        'bindings' => IlluminateRoutingMiddlewareSubstituteBindings::class,
        'cache.headers' => IlluminateHttpMiddlewareSetCacheHeaders::class,
        'can' => IlluminateAuthMiddlewareAuthorize::class,
        'guest' => AppHttpMiddlewareRedirectIfAuthenticated::class,
        'password.confirm' => IlluminateAuthMiddlewareRequirePassword::class,
        'signed' => IlluminateRoutingMiddlewareValidateSignature::class,
        'throttle' => IlluminateRoutingMiddlewareThrottleRequests::class,
        'verified' => IlluminateAuthMiddlewareEnsureEmailIsVerified::class,
        'adminLogin'=>AppHttpMiddlewareAdminLogin::class,
        'doctorLogin'=>AppHttpMiddlewareDoctorLogin::class,
        'patientLogin'=>AppHttpMiddlewarePatientLogin::class,
        'userLogin'=>AppHttpMiddlewareUserLogin::class,
        'appDoctorLogin'=>AppHttpMiddlewareAppDoctorLogin::class,
        'weChatAppLogin'=>AppHttpMiddlewareWeChatAppLogin::class,
        'hospitalLogin'=>AppHttpMiddlewareHospitalLogin::class,
        'diyapp'=>AppHttpMiddlewareAccessControllerAllowOrigin::class,
    ];

这样就可以去使用自己的路由了
