Angular 2无法加载预检的响应无效(重定向)[重复]

I am using Angular 2 with a Laravel PHP Framework for my API. My Angular 2 project is running on http://localhost:4200/ while my Laravel PHP Framework is running on http://localhost:80/laravel/public

When I run this in my Angular 2 Project:

getAllProfessionals():Observable<any> {
        return this.http.get(globals.baseUrl+'/professionals/', {headers:this.utilService.getHeadersJson()}).map(;

I get this error in my browser:

Failed to load http://localhost/laravel/public/api/v1/professionals/: Response for preflight is invalid (redirect)

globals.baseUrl is http://localhost/laravel/public/api/v1/

And here are the calls from this.utilService

getHeadersJson() {
        let headers = new Headers();
        headers.append('Accept', 'application/json');
        headers.append('Content-Type', 'application/json');
        headers.append('Authorization',  'Bearer ' + localStorage.getItem('token'));
        return headers;

    map(response: Response): any {
        return response.json();

What am I doing wrong here? Is there something wrong with my api call?

When I do this get call:

getCountrys(filter):Observable<any> {
            return this.http.get(globals.baseUrl+'/country/' + filter, {headers:this.utilService.getHeadersJson()}).map(;

That call to get Countrys works!

When I goto the URL: http://localhost/laravel/public/api/v1/professionals/

This is what returns:

Here are the routes from Laravel api.php file located in my routes folder:

Route::middleware('auth:api')->get('/user', function (Request $request) {
    return $request->user();

Route::group([ 'prefix' => 'v1'], function () {

    Route::resource('register', 'v1\RegisterController');
    Route::resource('paintype', 'v1\PainTypeController');
    Route::resource('painlevel', 'v1\PainLevelController');
    Route::resource('painkiller', 'v1\PainKillersController');
    Route::resource('profession', 'v1\ProfessionsController');
    Route::resource('qualification', 'v1\QualificationsController');
    Route::resource('specialities', 'v1\SpecialitiesController');
    Route::resource('problems', 'v1\ProblemsController');
    Route::resource('user', 'v1\UserController');
    Route::post('login', 'v1\AuthController@login');
    Route::post('professionals', 'v1\ProfessionalsController@store');
    Route::post('patients', 'v1\PatientsController@store');
    Route::get('country/{text}', 'v1\LocationController@getCountries');
    Route::get('region/{id}', 'v1\LocationController@getRegions');
    Route::get('city/{id}', 'v1\LocationController@getCities');
    Route::get('reviews/{username}', 'v1\ReviewController@show');

    Route::group(['middleware' => ['before' => 'jwt.auth']], function () {
        Route::resource('post-job', 'v1\PostJobController');
        Route::post('reviews', 'v1\ReviewController@store');
        Route::get('profile', 'v1\AuthController@profile');
        Route::get('jobs/listjob', 'v1\PostJobController@getMyJobs');

    The issue is CORS you need to on the server(backend) enable the CORS headers and allow the appropriate http methods. The entire thing is most likely on your PHP layer or whatever you use to serve the data.
