angular 4不向服务器发送cookie

Question

当我使用withCredentials时，我可以看到cookie被发送到服务器。但是发送任何东西到服务器。我使用laravel作为后端，使用angular 4作为前端。此外，cookie没有显示在chrome开发人员工具上，我无法使用它们访问它们。

另外，我在laravel中使用了Cors中间件：

<?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);
      $response->headers->set('Access-Control-Allow-Origin', 'http://localhost:4200');
      $response->headers->set('Access-Control-Allow-Methods', 'GET, POST, OPTIONS, PUT, PATCH, DELETE');
      $response->headers->set('Access-Control-Allow-Headers', 'Content-Type, Accept, Authorization, X-Request-With');
      $response->headers->set('Access-Control-Expose-Headers', 'Content-Disposition, x-total-count, x-filename');
      $response->headers->set('Access-Control-Allow-Credentials', 'true');

      return $response;

    }
}

当我第一次向服务器请求设置cookie时，以下响应显示：

Access-Control-Allow-Credentials:true

Access-Control-Allow-Methods:GET, POST, OPTIONS, PUT, PATCH, DELETE

当我从前端请求时：

refreshToken(){

const headers = new Headers({ 'Content-Type': 'application/json', 'Authorization': 'Bearer ' + this.getToken()})
let options = new RequestOptions({ headers: headers, withCredentials: true });
return this.http.post(API_DOMAIN + 'refresh', JSON.stringify({}), options)
  .map(
    (response) => {
      console.log(response);
      return response.json()
    },
  )
  .do(
    tokenData =>{
      localStorage.setItem('token', tokenData.access_token)
      localStorage.setItem('expires_in', tokenData.expires_in)
    }
  )
}

前端和后端服务器使用不同的端口。

Answer 1

您无法保存Cookie，因为您的开发node.js服务器和Laravel Vagrant框位于不同的域中。您可以做的是将来自node.js的调用代理到Laravel服务器。

在Angular应用程序的根目录中创建proxy.conf.json。放置一个包含路径的对象：

{
  "/api": {
    "target": "http://mydomian.test/",
    "secure": false
  }
}

我只是在这里定义了/api，因为我的所有后端URI都在api.php中。所有看起来像http://localhost:4200/api/someitems/1的电话都将被代理到http://mydomian.test/api/someitems/1。 然后编辑package.json并将start中scripts的值更改为ng serve --proxy-config proxy.conf.json。现在npm run start将从代理开始。我使用此代理的问题是它将您的URL（http://mydomian.test/）解析为IP。当它仅使用IP调用Laravel时，nginx服务器不知道该怎么做，因为它必须接收域名。 nginx允许同一IP上的多个网站，因此它必须接收域名或拥有一个默认网站，它重定向所有没有域名的呼叫。如果在Angular的代理中仍然没有修复它，请转到Laravel机器上的/etc/nginx/sites-available，那里你将有一个mydomian.test配置文件。它有listen 80;线，改为listen 80 default;。

现在你可以将API_DOMAIN变量更改为http://localhost:4200（或将它们全部删除）并禁用CORS。
