在ASP.NET全局异常处理5 [英] Global exception handling in ASP.NET 5

问题描述

我如何附上我自己的日志逻辑到ASP.NET 5应用程序来处理业务逻辑和下层抛出的每个异常？

How can I attach my own logging logic to an ASP.NET 5 application to handle each exception thrown in the business logic and lower layers?

我 ILoggerProvider 实施和Startup.cs loggerfactory.AddProvider（新LoggerProvider（配置））用自己的尝试。但似乎它拦截内ASP.NET的东西，而不是我抛出的异常的较低层。

I tried with own ILoggerProvider implementation and loggerfactory.AddProvider(new LoggerProvider(Configuration)) in Startup.cs. But it seems that it intercepts inner ASP.NET stuff, and not my thrown exceptions in lower layers.

推荐答案

的工作了，通过使用两个选项：

Worked it out, by using two options:

1）ILoggerProvider
实现从命名空间Microsoft.Framework.Logging自己ILoggerProvider和ILogger然后将其连接到MVC框架中添加Startup.cs以下code：

1) ILoggerProvider Implement your own ILoggerProvider and ILogger from the namespace Microsoft.Framework.Logging Then attach it to the MVC Framework in Startup.cs add following code:

 public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerfactory)
 {
        loggerfactory.AddProvider(new YourCustomProvider());
 }

但是，这上面的选项，似乎只能叫ILogger的写入功能MVC的具体事件，路由相关的等等，当我把我的下层例外，所以第二个选项摸索出它不叫：

But this above option, seems to only call the Write function of the ILogger on MVC specific events, routing related and so on, it wasn't called when I threw exceptions on my lower layers, so the second option worked out:

2）全局筛选
注册您自己ActionFilterAttribute实施Startup.cs：

2) Global Filter Register your own ActionFilterAttribute implementation in Startup.cs:

public void ConfigureServices(IServiceCollection services)
{
    services.AddMvc().Configure<MvcOptions>(options =>
    {
        options.Filters.Add(new YourCustomFilter());
    });
}

这一点很重要，即自定义过滤器类实现了个IExceptionFilter interace：

It's important, that the custom filter class implements the IExceptionFilter interace:

  public class YourCustomFilter : ActionFilterAttribute, IExceptionFilter
  {
             public void OnException(ExceptionContext context)
             {
              ///logic...
             }
 }

（)
然后在启动类中，我们添加过滤器：

() And then in the Startup class we add the filter:

    public void ConfigureServices(IServiceCollection services)
    {
         services.AddMvc(options =>
            {
                options.Filters.Add(new YourCustomFilter());
            });
    }
