Paypal高級定期結算使用快速結帳和使用託管頁面的信用卡付款

Question

在我的應用程序中，我需要使用paypal高級設置定期結算部分，並使用付款部分來執行相同操作。我需要Pay with PayPal按鈕流程（快速結帳流程）和信用卡付款才能創建定期配置文件。我最初的要求是這樣的：

public static PayPalRedirectAdv PayFlow() 
{ 

    NameValueCollection requestArray = new NameValueCollection() 
    { 

     {"PARTNER", "PayPal"},    // You'll want to change these 4 
     {"VENDOR", "merchantname"},   // To use your own credentials 
     {"USER", "username"}, 
     {"PWD", "abcdenfg"}, 
     {"TRXTYPE", "A"}, 
     {"AMT", "1.00"}, 
     {"CURRENCY", "USD"}, 
     {"CREATESECURETOKEN", "Y"}, 
     {"SECURETOKENID", "tokenId generated"}, 
     {"RETURNURL", UrlReturn}, 
     {"CANCELURL", UrlCancel}, 
     {"ERRORURL", lUrlError}, 
     {"BILLINGTYPE","RecurringBilling"} 

    }; 

    NameValueCollection resp = run_payflow_call(requestArray); // Will call the payflow end point via HttpWebRequest 
    if (resp["RESULT"] == "0") 
    { 
     string mode = "TEST"; 
     return new PayPalRedirectAdv 
     { 
      Url = "https://payflowlink.paypal.com?SECURETOKEN=" + resp["SECURETOKEN"] + "&SECURETOKENID=" + resp["SECURETOKENID"] + "&MODE=" + mode 
     }; 
    } 
    else 
    { 
     return new PayPalRedirectAdv { Url = string.Empty }; 
    } 
} 

一旦這個過程完成後，我已經設置了網址的iframe，它被嵌入在我在我的MVC項目的景色之一。當IFrame被加載時，它有兩個問題。

1）頁面被重定向到頂層。這意味着瀏覽器窗口被重定向到IFrame url。我選擇了佈局C作爲託管結帳頁面。當我使用演示項目中提供的憑證時，瀏覽器導航已解決;即Iframe在我的視圖中正確加載。 Paypal管理員設置中是否有任何設置來防止這種情況發生？我試圖通過沙盒頂級導航來解決這個問題，但是這不會讓我通過點擊「使用PayPal簽出」按鈕重定向到PayPal網站。

"TRXTYPE=R&TENDER=C&PARTNER=PayPal&VENDOR=Acme&USER=Acme&PWD=a1b2c3d4&ACTION=A&PROFILENAME=RegularSubscription&ORIGID=<PNREF>&START=12012002&PAYPERIOD= 
WEEK&TERM=12&OPTIONALTRX=S&OPTIONALTRXAMT=2.00&COMMENT1=First-time 
customer&AMT=42.00" 

這工作得很好，並在創建重複配置文件：

2）用信用卡付款，一旦交易成功，我將在現有的交易通過轉換爲輪廓。

但是，當我點擊「使用PayPal簽出」按鈕時，這將帶我到PayPal頁面，在那裏我可以使用我的Paypal憑證登錄到PayPal，然後當我點擊「paynow」按鈕時，它會從我的帳戶中扣除資金。這也有一個PNERF值，當我使用上面相同的代碼通過將Tender替換爲P來將事務轉換爲循環配置文件時，但它向我顯示了一條響應消息，即「找不到與此id對應的事務ID」。 PayPal結帳過程不顯示任何有關用戶要進入付款部分的信息。

此外，我跟着Express Checkout with recurring billing來完成任務，但我在DoExpressCheckout步驟中將BAID作爲空值。

我需要同時使用paypal付款和使用我的網站上的信用選項付款，因此我應該使用哪些參數來完成此操作？

在此先感謝。

嘗試使用此代碼....沒有DLL需要請求貝寶付款。
