OFX，开放金融交换，文件用于交换金融信息。它用于客户端服务器以及基于云的系统。因此，请求-响应模型用于交换财务信息。让我们学习一下 OFX 请求和响应：
解析 OFX 请求和响应 – C# API 安装
Aspose.Finance for .NET API 支持处理和解析财务数据的多种功能。您可以从 Downloads 部分下载它，或使用以下命令通过 NuGet 库安装：
PM> Install-Package Aspose.Finance
此外，这里值得一提的是 OFX 的演变。 OFX 版本 1 到 1.6 基于 SGML 语法。以后的版本依赖于 XML 规范。为了更好地理解，我们将以两种格式（1.03 和 2.2）创建 OFX 请求和响应文件。
使用 C# 以编程方式创建 OFX 请求
OFX 协议是一种双向交换金融数据的标准。您可以按照以下步骤轻松创建请求：
- 初始化 Ofx 请求文档 对象
- 创建 Sign on Request 实例
- 设置不同的属性
- 以 1.03 和 2.2 格式保存 OFX 请求
下面的代码片段解释了如何使用 C# 语言以编程方式创建 OFX 请求：
// 初始化 OfxRequestDocument 对象
OfxRequestDocument document = new OfxRequestDocument();
document.SignonRequestMessageSetV1 = new SignonRequestMessageSetV1();
// 初始化 SignonRequest 并设置不同的属性
SignonRequest signonRequest = new SignonRequest();
document.SignonRequestMessageSetV1.SignonRequest = signonRequest;
signonRequest.ClientDate = "20200611000000";
signonRequest.UserId = "aspose";
signonRequest.UserPassword = "password";
FinancialInstitution fi = new FinancialInstitution();
fi.Organization = "aspose";
fi.FinancialInstitutionId = "1";
signonRequest.FinancialInstitution = fi;
signonRequest.AppVersion = "1.0";
signonRequest.AppId = "Aspose.Finance";
signonRequest.ClientUserId = "aaaaaaa";
document.BankRequestMessageSetV1 = new BankRequestMessageSetV1();
StatementTransactionRequest stmtTransRequest = new StatementTransactionRequest();
document.BankRequestMessageSetV1.StatementTransactionRequests.Add(stmtTransRequest);
stmtTransRequest.TransactionUniqueId = "1111111";
stmtTransRequest.StatementRequest = new StatementRequest();
stmtTransRequest.StatementRequest.BankAccountFrom = new BankAccount();
stmtTransRequest.StatementRequest.BankAccountFrom.BankId = "sssss";
stmtTransRequest.StatementRequest.BankAccountFrom.AccountId = "sfsdfsfsdf";
stmtTransRequest.StatementRequest.BankAccountFrom.AccountType = AccountEnum.CHECKING;
stmtTransRequest.StatementRequest.IncTransaction = new IncTransaction();
stmtTransRequest.StatementRequest.IncTransaction.StartDate = "20200601000000";
stmtTransRequest.StatementRequest.IncTransaction.EndDate = "20200611000000";
stmtTransRequest.StatementRequest.IncTransaction.Include = true;
// 为两个版本创建 OFX 请求
document.Save(outputDir + @"newOfxRequestBankStatement.xml", OfxVersionEnum.V2x);
document.Save(outputDir + @"newOfxRequestBankStatement.sgml", OfxVersionEnum.V1x);
使用 C# 以编程方式创建 OFX 响应
您可以使用 C# 以编程方式在基于 .NET 的应用程序中创建 OFX 响应。以下步骤解释了 OFX 响应创建过程：
- 初始化 Ofx 响应文档 类对象
- 声明 Sign on Response 并设置值
- 使用 Ofx 版本枚举 枚举保存响应
以下代码片段显示了如何使用 C# 以编程方式创建 OFX 响应：
// 初始化 OfxResponseDocument 对象
OfxResponseDocument document = new OfxResponseDocument();
document.SignonResponseMessageSetV1 = new SignonResponseMessageSetV1();
// 初始化 SignonResponse 实例
SignonResponse signonResponse = new SignonResponse();
document.SignonResponseMessageSetV1.SignonResponse = signonResponse;
signonResponse.Status = new Status();
signonResponse.Status.Code = "0";
signonResponse.Status.Severity = SeverityEnum.INFO;
signonResponse.Status.Message = "SUCCESS";
signonResponse.ServerDate = "20200611";
signonResponse.ProfileUpdateDate = "20200611";
FinancialInstitution fi = new FinancialInstitution();
fi.Organization = "aspose";
fi.FinancialInstitutionId = "1";
signonResponse.FinancialInstitution = fi;
signonResponse.SessionCookie = "11111111111111111";
document.BankResponseMessageSetV1 = new BankResponseMessageSetV1();
StatementTransactionResponse stmtTransResponse = new StatementTransactionResponse();
document.BankResponseMessageSetV1.StatementTransactionResponses.Add(stmtTransResponse);
stmtTransResponse.TransactionUniqueId = "829631324";
stmtTransResponse.Status = new Status();
stmtTransResponse.Status.Code = "0";
stmtTransResponse.Status.Severity = SeverityEnum.INFO;
stmtTransResponse.StatementResponse = new StatementResponse();
stmtTransResponse.StatementResponse.Currency = CurrencyEnum.USD;
stmtTransResponse.StatementResponse.BankAccountFrom = new BankAccount();
stmtTransResponse.StatementResponse.BankAccountFrom.BankId = "1111111";
stmtTransResponse.StatementResponse.BankAccountFrom.AccountId = "1111111111111";
stmtTransResponse.StatementResponse.BankAccountFrom.AccountType = AccountEnum.CHECKING;
stmtTransResponse.StatementResponse.BankTransactionList = new BankTransactionList();
stmtTransResponse.StatementResponse.BankTransactionList.StartDate = "20200601000000";
stmtTransResponse.StatementResponse.BankTransactionList.EndDate = "20200611000000";
StatementTransaction transaction1 = new StatementTransaction();
transaction1.TransactionType = TransactionEnum.DEBIT;
transaction1.PostedDate = "20200611000000";
transaction1.TransactionAmount = "-12";
transaction1.FinancialInstitutionTransactionId = "1111111111111111111111111";
transaction1.Name = "bbbbbbbbbbbbbbbbbbbbbbb";
StatementTransaction transaction2 = new StatementTransaction();
transaction2.TransactionType = TransactionEnum.CREDIT;
transaction2.PostedDate = "20200611000000";
transaction2.TransactionAmount = "22222.11";
transaction2.FinancialInstitutionTransactionId = "2222222222222222222222222222";
transaction2.Name = "wwwwwwwwwwwwwwwwwwwwwwww";
stmtTransResponse.StatementResponse.BankTransactionList.StatementTransactions.Add(transaction1);
stmtTransResponse.StatementResponse.BankTransactionList.StatementTransactions.Add(transaction2);
stmtTransResponse.StatementResponse.LedgerBalance = new LedgerBalance();
stmtTransResponse.StatementResponse.LedgerBalance.BalanceAmount = "+2222.42";
stmtTransResponse.StatementResponse.LedgerBalance.DateAsOf = "20200611000000";
stmtTransResponse.StatementResponse.AvailableBalance = new AvailableBalance();
stmtTransResponse.StatementResponse.AvailableBalance.BalanceAmount = "+222222.42";
stmtTransResponse.StatementResponse.AvailableBalance.DateAsOf = "20200611000000";
// 以 OFX 1.03 和 2.2 格式规范保存响应
document.Save(outputDir + @"newOfxResponseBankStatement.xml", OfxVersionEnum.V2x);
document.Save(outputDir + @"newOfxResponseBankStatement.sgml", OfxVersionEnum.V1x);
结论
OFX 标准与平台无关，因此用户可以选择系统环境或平台来使用财务处理功能。它使银行、经纪公司和工资单处理公司能够创建量身定制的解决方案。您可以通过 免费支持论坛 取得联系。我们很乐意为您提供帮助！
