跨源请求阻止：在发送头的问题在Angular2 post请求到laravel [英] Cross-Origin Request Blocked: issue on sending headers in Angular2 post request to laravel

问题描述

我使用angular2 + laravel，我试图用头文件发布请求，但它给予跨原始请求阻止：错误。如果任何机构知道如何解决它。

I am using angular2+laravel and I am trying to post the request with headers but its giving Cross-Origin Request Blocked: error. If any body knows how to resolve it.

我做了一些可能的解决方案，如启用Access-Control-Allow-Origin*在htaccess文件的laravel和创建CORS中间件但这些解决方案不工作。这里是我的angular代码。

I did some possible solution like enable Access-Control-Allow-Origin "*" in htaccess file of laravel and created CORS Middleware but these solutions are not working. Here is my code of angular.

import { Injectable } from '@angular/core';
import { Http, Headers, Response, RequestOptions } from '@angular/http';
import { Observable } from 'rxjs/Observable';
import 'rxjs/add/operator/map'
import configApp = require('../_configs/app.settings');
//import '../assets/frontend/custom/js/jquery.toaster.config.js';
declare function maketoast(status: string, message: string) : void;


@Injectable()
export class ForgotpasswordService {

constructor(private http: Http) { }

forgotPassword(email: string, token: string) {

    alert(token)
    var headers = new Headers();

   // headers.append('Content-Type', 'application11/json');

    let headers = new Headers();
    headers.append("Authorization", "Bearer " + token;
    let options = new RequestOptions({ headers: headers });

    // console.log(configApp.apiUrl+/test);
    return this.http.post(configApp.apiUrl+"/password/email", JSON.stringify({ email: email, apiRequest:1}), options } )
        .map((response: Response) => {

            // login successful if there's a jwt token in the response
            let user = response.json();

            console.log(user.status);
            if(user.status == false){

                maketoast(user.toaster_status, user.message);
                event.stopImmediatePropagation;
                event.preventDefault();
                event.stopPropagation();

            }


            if (user.status == true) {

                maketoast(user.toaster_status, user.message);

            }
        });

}

resetPassword(token: string, email: string, password: string,     confirmPassword: string) {


    // console.log(configApp.apiUrl+/test);
    return this.http.post(configApp.apiUrl+"/password/reset",   JSON.stringify({ token: token, email: email, password: confirmPassword, confirmPassword: password, apiRequest:1}))
        .map((response: Response) => {

            // login successful if there's a jwt token in the response
            let user = response.json();

            console.log(user.status);
            if(user.status == false){

                maketoast(user.toaster_status, user.message);
                event.stopImmediatePropagation;
                event.preventDefault();
                event.stopPropagation();

            }


            if (user.status == true) {

                maketoast(user.toaster_status, user.message);

            }
        });

}

}

推荐答案

这是服务器端问题。

创建中间件：

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)
    {
        return $next($request)
            ->header('Access-Control-Allow-Origin', '*')
            ->header('Access-Control-Allow-Methods', 'GET, POST, PUT, DELETE, OPTIONS');
    }
}

并添加到您的路线：

Route::group(['middleware' => ['cors']], function () {

//您的路由代码
}）;

//YOUR route code });
