Backbone.js 使用Laravel和Omnipay的访问控制允许始发站

我试图从主干网发出一个Ajax post请求，将Laravel路由称为“pay”，但我总是从控制台日志中得到这个答案：

XMLHttpRequest cannot load https://www.sandbox.paypal.com/webscr?cmd=_express-checkout&useraction=commit&token=EC-5S932878HU8059629. Origin http://localhost is not allowed by Access-Control-Allow-Origin. 

我试图修改我的MAMP httpd.conf以接受跨域脚本，正如您所看到的，我向routes.php添加了一条头指令。 以下是我的JS代码：

Backbone.ajax({
        url:'index.php/pay',
        type:'POST',
        dataType:"json",
        data: converteditems,
        crossDomain: true,
        success:function (data) {
            if(data.error) {  // If there is an error, show the error messages
                $('.alert-error').text(data.error.text).show();
           }         
        }
    });

这是Laravel中的routes.php：

<?php
header('Access-Control-Allow-Origin: *');
Route::get('/', function()
{
return View::make('home');
});

Route::resource('products','ProductsController');

Route::resource('login', 'AuthenticationController');

Route::post('pay','PaypalController@doPay');

如果您希望从Ajax发出请求，那么您不希望omnipay立即将该请求重定向到paypal。您希望将客户的浏览器重定向到paypal

因此，您需要在控制器操作中加入一些逻辑，因此如果它是一个XHR请求，那么只需返回URL将客户转发到

例如，在omnipay响应上使用$response->getRedirectUrl（），而不是$response->redirect（）。然后将其放入JSON响应或其他内容中，并使用JavaScript将客户浏览器发送到该URL
