我正在尝试从 Backbone 发出 Ajax 发布请求,将 Laravel 路由称为“付费”,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. 

我尝试修改我的 MAMP httpd.conf 以接受跨域脚本,如您所见,我已在 routes.php 中添加了标题指令。这是我的 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');

doPay 方法以这种方式使用 Omnipay 包(用于测试目的 ofc):

public function doPay()

{          

$gateway = GatewayFactory::create('PayPal_Express');
$gateway->setUsername('blablablabla-facilitator_api1.gmail.com'); 
$gateway->setPassword('137787773');
$gateway->setSignature('AhFvPK5rU.kfQOKIwZcYO1yItmtHASGDFDFGDbY9.w');
$gateway->setTestMode('true');
$args['amount']='2.00';
$args['description']='Your purchase';
    $args['returnUrl']='http://localhost/shoppingcart/index.php/return';
    $args['cancelUrl']='http://localhost/shoppingcart/index.php/cancel';

try {

$response = $gateway->purchase($args)->send();

if ($response->isSuccessful()) {
$responsereturn=$response->getData();         
} elseif ($response->isRedirect()) {    
    $response->redirect();
} else {   
    exit($response->getMessage());
}
} catch (\Exception $e) { 
exit('internal error, log exception and display a generic message to the customer');
 }
}

如果您想从 Ajax 发出请求,那么您不希望omnipay 立即将该请求重定向到贝宝。您想将客户的浏览器重定向到贝宝。

所以你需要在你的控制器动作中加入一些逻辑,所以如果它是一个 XHR 请求,那么只需返回 URL 以将客户转发到。

例如,在omnipay 响应中使用$response->getRedirectUrl() 而不是$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。
