Laravel6.X 跨域问题解决方案

简要说明：新项目比较小，所以尝试了 6.0 版本的 Laravel 框架。之前的项目用的是 barryvdh/laravel-cors 这个包，但是目前不支持 6.X 系统的，所以贴出这个项目的解决方案。

自定义中间件

第一步：创建中间件

php artisan make:middleware EnableCrossRequestMiddleware

第二步：编辑中间件

<?php namespace App\Http\Middleware; use Closure; class EnableCrossRequestMiddleware{ /** * @param $request * @param Closure $next * @return mixed */ public function handle($request, Closure $next) { header('Content-Type: text/html;charset=utf-8'); header('Access-Control-Allow-Origin:*'); header('Access-Control-Allow-Methods:POST,GET,PUT,OPTIONS,DELETE'); // 允许请求的类型 header('Access-Control-Allow-Credentials: true'); // 设置是否允许发送 cookies header('Access-Control-Allow-Headers: Content-Type,Access-Control-Allow-Origin,Access-token,Content-Length,Accept-Encoding,X-Requested-with, Origin,Access-Control-Allow-Methods'); // 设置允许自定义请求头的字段 return $next($request); } }

第三步：注册中间件（全局）

<?php namespace App\Http; use Illuminate\Foundation\Http\Kernel as HttpKernel; class Kernel extends HttpKernel { /** * The application's global HTTP middleware stack. * * These middleware are run during every request to your application. * * @var array */ protected $middleware = [ //other \App\Http\Middleware\EnableCrossRequestMiddleware::class, ]; Copy

数据校验  https://www.jianshu.com/p/3ab62ae877d0

use Illuminate\Support\Facades\Validator; $params = $request->all(); $validator = Validator::make($request->all(), [ 'category_name' => 'required', 'parent_id' => 'required', ],[ 'category_name.required'=>'分类不能为空!', 'parent_id.required'=>'顶级菜单不能为空', ]); if ($validator->fails()) { $rsp['err_msg'] = "数据校验失败"; $rsp['data'] = $validator->errors()->all(); //return response()->json($rsp); return $this->getResponse('',ResponseCode::OK,$rsp); }
