原来是showHostedThankyouPage=true 导致了这个问题。
我正在使用 .NET 按钮 API 生成对 iFrame 的请求,如下所示:
var service = new PayPalAPIInterfaceServiceService(GetConfig(request));
var createButtonResponse = service.BMCreateButton(new BMCreateButtonReq
{
BMCreateButtonRequest = new BMCreateButtonRequestType
{
ButtonType = ButtonTypeType.PAYMENT,
ButtonCode = ButtonCodeType.TOKEN,
ButtonCountry = countryCodeType,
ButtonVar = new List<string>
{
String.Format("subtotal={0}", _salesOrderPriceService.GetGrossTotal(request.Order)),
String.Format("notify_url={0}", request.NotifyUrl),
String.Format("return={0}", request.ReturnUrl),
String.Format("invoice={0}", request.Order.Id),
String.Format("currency_code={0}", request.Order.Currency.Code),
String.Format("cancel_return={0}", request.CancelReturnUrl),
"billing_first_name=test",
"billing_last_name=tset",
"billing_address1=test",
"billing_city=test",
"billing_state=tes",
"billing_zip=test",
"billing_country=GB",
"template=templateD",
"paymentaction=sale",
"business=tset"
}
}
});
我将showHostedThankyouPage=true 包含在导致问题的名称值对中。删除它就解决了。
