貝寶付款使用JavaScript重定向時無效？

我有Paypal SDK REST，ASP.NET MVC 5（C＃）和javascript重定向的問題。貝寶付款使用JavaScript重定向時無效？

我創建了所有必需的組件（ItemList，Address，Details，Amount，...）來爲PayPal創建支付對象（不使用信用卡，所以FundingInstruments爲空）。在創建之後，我使用JavaScript重定向的View將URL Payment對象提供給我。但每次我看到'交易無效...'

但是，如果我複製/粘貼URL（「https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_express-checkout&token= ...」）到我的瀏覽器手動，它的工作原理！我要瘋了...

請問你有解決方案嗎？（發現包圍的C＃文件，JSON格式的付款和小HTML重定向組件），使用系統

C＃付款類

; using System.Collections.Generic;使用System.Linq的 ; using System.Web;使用PayPal的 ;使用PayPal.Api的 ; using System.Configuration;使用System.Threading的 ;

爲了記錄在案，這裏是我如何固定它：

好吧，這是我的錯，重定向是不是我想像的要......要解決它，不要不要忘了把你的URL從RAZOR放到RAW模式:)。

<script> 
    setTimeout(function() { 
     var url = '**@Html.Raw(Model.Url)**'; 
     alert('Redirect to: ' + url); 
     window.location.href = url; 
    }, 1000); 
</script>

無論如何，感謝貝寶隊試圖幫助，但爲時已晚:)
