No ‘Access-Control-Allow-Origin’ header – LaravelXMLHttpRequest cannot load http://myapi/api/rating. Response to preflight request doesn’t pass access control check: No ‘Access-Control-Allow-Origin’ header is present on the requested resource. Origin ‘http://localhost:8104‘ is therefore not allowed access. The response had HTTP status code 403. Show I can’t figure out why I can’t make CORS requests. I’ve install the middleware here, added it to the global http kernel, but it still doesn’t work. Tried to create a custom middleware given stackoverflow suggestions but that also did not work. Also tried adding a Route group. Lastly, I tried setting the response headers manually in the request action. I’m really stuck – help is appreciated! See for code: https://gist.github.com/KerryRitter/0d7ababb7b9eb8d54f0ae55add9704a1 AnswerIf you are using Laravel 5.5 & Laravel 5.x and facing same problem like No 'Access-Control-Allow-Origin' header is present on the requested resource. Just use following package and config your system. Step 1: composer require barryvdh/laravel-cors Step 2 You also need to add CorsServiceProvider to your config/app.php providers array: FruitCakeCorsCorsServiceProvider::class, To allow CORS for all your routes, add the HandleCors middleware in the $middleware property of app/Http/Kernel.php class: For global uses: protected $middleware = [ // ... FruitcakeCorsHandleCors::class, ]; For middleware uses: protected $middlewareGroups = [ 'web' => [ // ... ], 'api' => [ // ... FruitcakeCorsHandleCors::class, ], ]; Step 3 Once your installation completed run below command to publish the vendor files. php artisan vendor:publish --provider="FruitcakeCorsServiceProvider" Hope this answer helps someone facing the same problem as myself. I was woking on a Laravel API application for Angular. When I was working locally everything was working fine.

This issue can be solved by adding appropriate headers in Laravel application. You can set this by adding Middleware in these routes. Here is the middleware file at /app/Http/Middleware/CORS.php <?php namespace App\Http\Middleware; use Closure; class CORS { /** * Handle an incoming request. * * @param \Illuminate\Http\Request $request * @param \Closure $next * @return mixed */ public function handle($request, Closure $next) { $response = $next($request) ->header('Access-Control-Allow-Origin', '*') ->header('Access-Control-Allow-Methods', 'POST, GET, OPTIONS, PUT, DELETE') ->header('Access-Control-Allow-Headers', 'Origin, Content-Type, X-Auth-Token'); } }Add the middleware to $routeMiddleware variable in app/Http/Kernel.php file. protected $routeMiddleware = [ .... 'CORS' => \App\Http\Middleware\CORS::class, .... ];And add the middleware to route. Route::get('/users/get-data','[email protected]')->middleware('CORS');This should work and solve the issue.

Create API in LaravelTo enable CORS in API, we need to have one, go to routes/api.php and incorporate the given below code. Make Http GET Request with AJAXWe will send the Http GET request using AJAX. To, manifest a new HTML template, name it demo.html. Call jQuery CDN link and define the AJAX function and pass the Laravel API to get the response. <!doctype html> <html lang="en"> <head> <!-- Required meta tags --> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no"> <!-- Bootstrap CSS --> <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css" integrity="sha384-JcKb8q3iqJ61gNV9KGb8thSsNjpSL0n8PARn9HuZOnIxN0hoP+VmmDGMN5t9UJ0Z" crossorigin="anonymous"> <title>Laravel CORS Middleware Demo</title> </head> <body> <script src="https://cdn.jsdelivr.net/npm//dist/jquery.min.js"></script> <script> $.ajax({ type: "GET", dataType: "json", url: 'http://localhost:8000/demo-url', success: function (data) { console.log(data); } }); </script> </body> </html>Malevolent Laravel CORS ErrorAs we can see a CORS related error (No ‘Access-Control-Allow-Origin’ header is present on the requested resource.), it occurred because we have two different domain trying to exchange data with each other. And yes we haven’t even enabled the CORS yet. Access to XMLHttpRequest at 'http://localhost:8000/demo-url' from origin 'null' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.Installing CORS Package in LaravelAs we have known what the ailment is, and now turn to cure this. With the help of Composer just Install fruitcake/laravel-cors package. composer require fruitcake/laravel-corsRegistering CORS MiddlewareWe have added the quintessential CORS (Cross-Origin Resource Sharing) headers support in your Laravel application.
