无法从QuickBooks QBOConceptsTutorial-DotNet示例应用获取Token

我正在学习使用QuickBooks API，将自有应用与平台后端集成，实现发票和客户记录的请求功能。从QuickBooks开发者网站的Git仓库下载了QBOConceptsTutorial-DotNet示例应用，但该应用无法启动，HTTPS调用失败。于是我在Visual Studio 2022社区版中创建了一个类似的新应用，复制了所有必要代码，新应用可以正常启动，也能通过Sandbox账号和密钥凭证连接到QuickBooks Sandbox公司。

回调返回的变量没有错误，但点击“Get Token”模块时，执行以下代码时出现失败：

var tokenClient = new TokenClient(AppController.tokenEndpoint, AppController.clientid, AppController.clientsecret);

错误信息及堆栈跟踪如下：

Line 68:{
Line 69:             //Request Oauth2 tokens
Line 70:             var tokenClient = new TokenClient(AppController.tokenEndpoint, AppController.clientid, AppController.clientsecret);
Line 71: 
Line 72:

问题原因 #

这个MissingMethodException是Serilog版本不兼容导致的：QuickBooks的OAuth2 SDK依赖特定版本的Serilog（尤其是Serilog.Sinks.File包），而你项目中引用的Serilog版本没有SDK调用的那个File方法重载，所以实例化TokenClient时触发了错误。

解决步骤 #

• 检查并对齐Serilog版本
  打开项目的NuGet包管理器，查看当前安装的Serilog和Serilog.Sinks.File版本；查看Intuit.Ipp.OAuth2PlatformClient包的依赖项，找到它要求的Serilog版本；卸载当前的Serilog相关包，安装与SDK兼容的版本。
• 清理并重新生成项目
  删除项目的bin和obj文件夹；在Visual Studio中执行清理解决方案，再执行生成解决方案。
• 禁用SDK的Serilog日志（可选）
  如果不想调整包版本，可以在实例化TokenClient前关闭SDK的高级日志功能，示例代码：

  // 关闭文件日志等高级日志配置
  Intuit.Ipp.OAuth2PlatformClient.Diagnostics.OAuthAdvancedLogging.DisableLogging();
  var tokenClient = new TokenClient(AppController.tokenEndpoint, AppController.clientid, AppController.clientsecret);
