https://github.com/paypal/rest-api-sdk-dotnet请调查一下
或者你可以使用
payflow_dotnet.dll
请查看 payflow_dotnet.dll 的代码
public void CreateAuthorization()
{
// Create the Payflow Connection data object with the required connection details.
// The PAYFLOW_HOST property is defined in the webconfig
PayflowConnectionData Connection = new PayflowConnectionData();
// Create Invoice
Invoice Inv = new Invoice();
// Set Amount
Currency Amt = new Currency(new decimal(premiumAmount), "USD");
//adding the amount to invoice
Inv.Amt = Amt;
//creating a new express check out request
ExpressCheckoutRequest currRequest = new ECSetRequest(WebConfigkeys.ReturnToApplication, WebConfigkeys.ReturnToApplication);
PayPalTender currTender = new PayPalTender(currRequest);
//creating a new transaction
SaleTransaction currTransaction = new SaleTransaction(User, Connection, Inv, currTender, PayflowUtility.RequestId);
//submitting the transaction and accepting the response message
Response Resp = currTransaction.SubmitTransaction();
if (Resp != null)
{
TransactionResponse TrxnResponse = Resp.TransactionResponse;
ExpressCheckoutResponse eResponse = Resp.ExpressCheckoutSetResponse;
if ((TrxnResponse != null) && (eResponse != null))
{
eResponse.Token;//get your token
}
}
}
将此添加到 Web Config
