我正在使用貝寶沙箱。在客戶付款後的我的項目中，我必須將正式收據編號存儲到數據庫中。所以我創建了一個作爲我的返回URL的servlet，我想根據事務ID檢索OR數。我使用buynow按鈕使用標準付款方式。這是我獲取交易細節的代碼。貝寶沙箱響應中未返回的收據編號
HttpClient client = HttpClients.createDefault();
HttpPost post = new HttpPost("https://api-3t.sandbox.paypal.com/nvp");
List<NameValuePair> params = new ArrayList<>();
params.add(new BasicNameValuePair("METHOD","GetTransactionDetails"));
params.add(new BasicNameValuePair("VERSION","124.0"));
params.add(new BasicNameValuePair("USER", "morbidcode666_api1.gmail.com"));
params.add(new BasicNameValuePair("PWD","L66QPRP2RTRB9NEA"));
params.add(new BasicNameValuePair("SIGNATURE", "AUT-r5lylj2D9Bdu1rj5Xzp05w8eAMod08fTK-pwniTNTHScwi4w9jdh"));
params.add(new BasicNameValuePair("TRANSACTIONID",request.getParameter("tx")));
post.setEntity(new UrlEncodedFormEntity(params, "UTF-8"));
HttpResponse postresponse = client.execute(post);
HttpEntity entity = postresponse.getEntity();
System.out.println(EntityUtils.toString(entity));
據https://developer.paypal.com/docs/classic/api/merchant/GetTransactionDetails_API_Operation_NVP/，
