Laravel 5 + AngularJS 跨域 CORS

Laravel 5 + AngularJS Cross Domain CORS

我到处寻找答案,但到目前为止没有任何效果。堆栈上列出的所有解决方案都没有被证明是足够的。

我的 laravel 日志中没有任何错误形式,我只得到标准:

XMLHttpRequest cannot load http://api.domain.dev/post/. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://domain.dev' is therefore not allowed access.

Laravel 控制器:

<?php namespace App\Http\Controllers;

use App\Http\Requests;
use App\Http\Controllers\Controller;
use App\Post;
use App\Tag;
use Illuminate\Http\Request;

class PostController extends Controller {

    /**
     * Display a listing of the resource.
     *
     * @return Response
     */
    public function index()
    {

        $posts = Post::with('user', 'tags')->get();

        return response()->json($posts);
    }
}

Laravel 路线:

<?php

Route::resource('user', 'UserController');
Route::resource('post', 'PostController');
Route::get('post/tag/{tag}', 'PostController@postsWithTag');
Route::resource('tag', 'TagController');

Route::controllers([
    'auth' => 'Auth\AuthController',
    'password' => 'Auth\PasswordController',
]);

有点臃肿没有条理angular:

//App
var app = angular.module('app', [
    'ngRoute',
    'ngAnimate'
    ]);

//Config
app.config(['$routeProvider', '$locationProvider', '$animateProvider', function($routeProvider, $locationProvider, $animateProvider) {

    $locationProvider.html5Mode(true).hashPrefix('!');

    $routeProvider.
    when('/', {
        templateUrl: 'partials/home.html',
        controller: 'PageController'
    }).
    when('/about', {

        controller: 'AboutController'

我不知道从这里去哪里。 我已经尝试了从正常的 header() 实现到使用 laravel-cors 包通过过滤器和控制器中的 _construct 实现的所有方法。 我也走了服务器配置路线并尝试将 header 添加到 .htaccess 和虚拟主机配置中。

在return之前添加这一行header("Access-Control-Allow-Origin: *");

您的代码应该是

public function index()
{
    $posts = Post::with('user', 'tags')->get();
    header("Access-Control-Allow-Origin: *");
    return response()->json($posts);
}

我不太了解 laravel.but 我的建议是请求 headers 访问 REST 方法(GET,POST,PUT,DELTE)和特定来源您通过以下方式从哪个域发出请求的域,或者设置为“*”(它允许任何域)

header('Access-Control-Allow-Origin', 'some url');
header('Allow', 'GET, POST, OPTIONS');
header('Access-Control-Allow-Headers', 'Origin, Content-Type, Accept, Authorization, X-Request-With');
header('Access-Control-Allow-Credentials', 'true');

在 angular js.If 您使用 <1.2 您可以在控制器文件中设置 CORS,如下所示 way.In 不需要最新版本它将设置 default.you 需要设置什么您期望从服务器默认获得的内容类型是 json.If 您期望您可以在请求中手动设置的其他类型的内容。

myApp.config(['$httpProvider', function($httpProvider) {
            $httpProvider.defaults.useXDomain = true;
            delete $httpProvider.defaults.headers.common['X-Requested-With'];
        }
    ]);

当您调用跨源 XHR 请求时,javascript 首先向给定的 URL 触发 OPTIONS 请求。如果此方法未添加到您的路由中,则它会弹出一个 404 页面,该页面在没有 ACAO header 的情况下提供,因此不会发送具体的 POST 请求,因为 javascript 看到它不允许.

添加

<?php header("Access-Control-Allow-Origin: *"); ?>

到public/index.php如果它在蓝铃之类的函数中不起作用建议

将这些行添加到您的 public/index.php:

header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Methods: GET, POST, PATCH, PUT, DELETE, OPTIONS');
header('Access-Control-Allow-Headers: Origin, Content-Type, X-Auth-Token'); // allow certain headers 

看看,是否有效。

我遇到了同样的问题,但是 jQuery 我花了几个星期才找到一个好的解决方案。

我的情况是创建一个中间件来设置 headers 是完美的解决方案。

创建Cors中间件:App\Http\Middleware\Cors.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)
    {
        return $next($request)
            ->header('Access-Control-Allow-Origin', $_SERVER['HTTP_ORIGIN'])
            // Depending of your application you can't use '*'
            // Some security CORS concerns 
            //->header('Access-Control-Allow-Origin', '*')
            ->header('Access-Control-Allow-Methods', 'POST, OPTIONS')
            ->header('Access-Control-Allow-Credentials', 'true')
            ->header('Access-Control-Max-Age', '10000')
            ->header('Access-Control-Allow-Headers', 'Content-Type, Authorization, X-Requested-With');
    }
}

记得在里面设置Cors别名App\Http\Kernel

protected $routeMiddleware = [
    ...
    'cors' => \App\Http\Middleware\Cors::class,
];

在路由内部,您可以将中间件与组一起使用或直接指向特定路由,例如:

Route::match(['post', 'options'], 'api/...', 'Api\XController@method')->middleware('cors');

如果有人在使用jQuery时遇到这个问题,我建议使用$.ajax,而不是$.get、$.post。使用此方法时,jQuery 使用 XMLHttpRequest 发送数据并将 content-type 设置为 application/x-www-form-urlencoded,无法更改,因此请使用 Ajax.

例如:

        $.ajax({
            type: 'POST',
            url: 'www.foo.bar/api',
            contentType: "application/json",
            xhrFields: {
                // The 'xhrFields' property sets additional fields on the XMLHttpRequest.
                // This can be used to set the 'withCredentials' property.
                // Set the value to 'true' if you'd like to pass cookies to the server.
                // If this is enabled, your server must respond with the header
                // 'Access-Control-Allow-Credentials: true'.
                withCredentials: true

            },

            headers: {
                // Set any custom headers here.
                // If you set any non-simple headers, your server must include these
                // headers in the 'Access-Control-Allow-Headers' response header.
                'Accept': 'application/json'
            },



            data: '{"some":"json data"}',
            success: function (data) {
                console.log('AJAX version');
                console.log("Works!")
            },
        });

记住:如果您根据要求使用 application/json header,您必须提供 "OPTIONS" 方法来进行预检。

我做了什么,但不确定这是否是最好的解决方案,但那个没有任何问题

1.build angular 通常使用 ng build --prod

2.move angular/distlaravel/public

的内容

3.then 在 laravel/routes/web.php

中使用这个简单的代码
Route::prefix('api')->group(function () {
    Route::get('/', function () {
    return view('welcome');
    });
});
Route::get('/{params?}', function () {
//    return view('welcome');
    include_once '../public/index.html';
})->where('params', '(.*)');

现在所有请求都到达 Laravel,如果它可以通过路由捕获请求,则该路由将起作用,否则它将传递给 angular
