Question

好像我需要配置日志记录。我可以添加工作和在/ hangfire页面中看到它们但是如果我禁用app.UseHangfireServer（）它们将不会触发。

由于这是一个简单的基于文件夹的网站，我已经从运行示例Hangfire MVC项目中将必要的dll复制到我的bin文件夹。如果需要，我该如何配置记录器？

Error location:

Line 17:         {
Line 18:             app.UseHangfireServer();
Line 19:             app.UseHangfireDashboard();
Line 20: 

Source File: f:\hangfire\App_Code\Startup.cs    Line: 18

Answer 1

我个人使用Elmah（Hangfire会在较新版本中自动检测到）。

但是如果要关闭它，将日志提供程序设置为null应该可以解决问题（您可以将其放在应用程序的启动方法中，这将根据您使用的机制而有所不同执行启动）

LogProvider.SetCurrentLogProvider(null);

Answer 2

您的解决方案是否应用了任何记录器库？正如Hangfire文档所说：

从Hangfire 1.3.0开始，如果是，则无需执行任何操作   您的应用程序已经使用以下库之一   反思（以便Hangfire本身不依赖于任何一个   他们）。通过检查自动选择记录实现   按以下顺序存在相应的类型。

Serilog   NLOG   log4net的   EntLib   记录放大镜   ELMAH   如果你想记录   Hangfire事件并没有安装日志库，请选择   以上之一并参考其文档

据我了解你需要一些上面列出的日志库。

Answer 3

我有两个创业点：

[assembly: OwinStartup(typeof(MyWebApplication.Startup))]

和

[ApplicationStartup]

删除[ApplicationStartup]并将Hangfire相关代码移动到其他位置以解决问题。

Answer 4

您必须添加日志提供程序。作为示例，您可以像这样添加一个构建提供程序：

LogProvider.SetCurrentLogProvider（new ColouredConsoleLogProvider（））;

它应该解决错误。
