エクスプレスチェックアウトを使用してPayPalを使用して、請求契約IDを取得しています。
私はこのガイドに従っていました:
「SetExpressCheckout」を実行するときの最初のステップ:以下はコードです
public string SetExpressCheckout(string Amount)
{
string returnURL = "http://localhost:50325/ReviewOrder.aspx" + "?amount=" + Amount + "&PAYMENTREQUEST_0_CURRENCYCODE=USD";
string cancelURL = returnURL.Replace("ReviewOrder", "ExpCheckOut");
string strCredentials = "USER=" + strUsername + "&PWD=" + strPassword + "&SIGNATURE=" + strSignature;
string strNVP = strCredentials;
strNVP += "&PAYMENTREQUEST_0_PAYMENTACTION=AUTHORIZATION&&PAYMENTREQUEST_0_AMT=25" + "&L_BILLINGTYPE0=MerchantInitiatedBilling" + "&RETURNURL=" + returnURL;
strNVP += "&CANCELURL=" + cancelURL;
strNVP += "&METHOD=SetExpressCheckout&VERSION=" + strAPIVersion + "&DESC=test EC payment" +"&NOSHIPPING=0" ;
//Create web request and web response objects, make sure you using the correct server (sandbox/live)
HttpWebRequest wrWebRequest = (HttpWebRequest)WebRequest.Create(strNVPSandboxServer);
//Set WebRequest Properties
wrWebRequest.Method = "POST";
// write the form values into the request message
StreamWriter requestWriter = new StreamWriter(wrWebRequest.GetRequestStream());
requestWriter.Write(strNVP);
requestWriter.Close();
// Get the response.
HttpWebResponse hwrWebResponse = (HttpWebResponse)wrWebRequest.GetResponse();
StreamReader responseReader = new StreamReader(wrWebRequest.GetResponse().GetResponseStream());
// and read the response
string responseData = responseReader.ReadToEnd();
responseReader.Close();
return responseData;
}
応答は次のとおりです。

ステップ3でBillingAgreeentdを取得する方法。
ステップ3のコードは次のとおりです。
public string GetBillingAgreementID()
{
string returnURL = "http://localhost:50325/ReviewOrder.aspx" + "?amount=" + Amount + "¤cy=USD";
string cancelURL = returnURL.Replace("ReviewOrder", "ExpCheckOut");
string strCredentials = "USER=" + strUsername + "&PWD=" + strPassword + "&SIGNATURE=" + strSignature;
string strNVP = strCredentials;
strNVP += "&RETURNURL=" + returnURL;
strNVP += "&CANCELURL=" + cancelURL;
strNVP += "&METHOD=CreateBillingAgreement&VERSION=" + strAPIVersion + "&TOKEN=" + Session["Token"];
//Create web request and web response objects, make sure you using the correct server (sandbox/live)
HttpWebRequest wrWebRequest = (HttpWebRequest)WebRequest.Create(strNVPSandboxServer);
//Set WebRequest Properties
wrWebRequest.Method = "POST";
// write the form values into the request message
StreamWriter requestWriter = new StreamWriter(wrWebRequest.GetRequestStream());
requestWriter.Write(strNVP);
requestWriter.Close();
// Get the response.
HttpWebResponse hwrWebResponse = (HttpWebResponse)wrWebRequest.GetResponse();
StreamReader responseReader = new StreamReader(wrWebRequest.GetResponse().GetResponseStream());
// and read the response
string responseData = responseReader.ReadToEnd();
responseReader.Close();
return responseData;
}
応答は次のとおりです。
TIMESTAMP=2013-03-25T00:51:34Z&
CORRELATIONID=854e6beed1e82&
ACK=Failure&
VERSION=86&
BUILD=5479129&
L_ERRORCODE0=11455&
L_SHORTMESSAGE0=Buyer did not accept billing agreement&
L_LONGMESSAGE0=Buyer did not accept billing agreement&
L_SEVERITYCODE0=Error
BillingAgreemntIdを取得する方法は?「L_SHORTMESSAGE0=マーチャントが参照トランザクションに対して有効になっていない」ため、「SetExpressCheckout」からのこのメッセージはBillingAgreementIDを取得できませんか?
これについて私を助けてください。ありがとう。
