沙盒 Paypal 扣款问题

Question

    {
    echo "payment cancelled by the user";
    }

function paiement_succes()
{
  // Obtain the token from PayPal.
  if(!array_key_exists('token', $_REQUEST)) 
         exit('Token is not received.');
  // Set request-specific fields.
  $token = urlencode(htmlspecialchars($_REQUEST['token']));
  // Add request-specific fields to the request string.
  $nvpStr = "&TOKEN=$token";
  // Execute the API operation; see the PPHttpPost function above.
  $httpParsedResponseAr = $this->PPHttpPost('GetExpressCheckoutDetails', $nvpStr);
  if("SUCCESS" == strtoupper($httpParsedResponseAr["ACK"]) || "SUCCESSWITHWARNING" == strtoupper($httpParsedResponseAr["ACK"])) 
      {
          //print_r($httpParsedResponseAr);

我在 Paypal 沙盒中有三个帐户：两个企业帐户和一个个人帐户。我所有的 Paypal 帐户都将美元作为默认货币。

在上面的代码中，我使用欧元作为货币。

当我进行交易时，如果我从我的个人（买家）账户中以欧元付款，那么我的买家账户中的钱会被扣除（等值的美元金额会从我的买家账户中扣除）。这完全没问题，没有问题。

问题是我的企业或（卖家）帐户中没有添加任何金额。

我在 Stack Overflow 上发现了一篇帖子，内容如下：

如果交易的货币代码和卖家账户没有 匹配，然后钱不会被添加到卖家帐户中

我把欧元换成了美元，（因为我的沙盒卖家测试账户是美元），发现兑换成美元后，我的钱就会被添加到我的卖家账户中。

这只是沙盒的问题，还是也适用于 live paypal？

我有一个网站，买家可以用英镑、欧元、马币、新加坡元、澳元付款。

如果交易需要以特定货币进行，即卖家账户设置的货币，则无需使用不同的货币。

由于 SetExpressCheckOut 中传入的 currencyCode 应该与 DoExpressCheckout 匹配，而且我遇到了问题，因此 currencyCode 需要与沙盒卖家账户的相同，所以即使买家选择 GBP，我也必须将其发送到设置ExpressCheckout为卖家账户的currencyCode。

Answer 1

您应该通过相关企业帐户的控制面板添加您希望接收付款的货币。

转到Profile -> My Settings -> 财务信息选项卡和Currency Balances。从那里选择一种货币并将其添加到列表中。然后，您收到的付款将保留在相应的货币余额中，直到您将其转换为您想要的任何形式。

Answer 2

默认情况下，以您不持有的货币进行的交易将被保留，直到您决定如何处理它们。如果您登录有问题的卖家账户，您应该会在您的历史记录下看到该交易。您应该能够从那里接受或拒绝它。

有两种解决方法：

• 如 Alderis 所述，将欧元作为货币余额添加到您的卖家账户中。
• 自动接受以您不持有的货币进行的所有交易并将其转换为美元。为此，请登录卖家账户，点击Profile，然后点击Payment Receiving Preferences（在Selling preferences列中），然后将以我不持有的货币发送给我的付款设置为否，接受并将其转换为美元，然后点击保存。
