logo Enterprise-level component library based on Bootstrap and Blazor

Global exception

Added component ErrorLogger Through this component, global logs and exceptions can be output uniformly; currently, the Blazor framework does not provide a MVC like Global exception The overall solution


1. Add AddLogging to the Startup file to enable the net core system log function

Use AddFileLogger need to reference Longbow.Logging component package
public void ConfigureServices(IServiceCollection services)
    services.AddLogging(builder => builder.AddFileLogger());

2. Use BootstrapBlazorRoot to wrap the content


3. Use cascading parameters in the code to get examples

private void OnClick()
    var a = 0;
    _ = 1 / a;

4. Console or IIS output visible log information

crit: BootstrapBlazor.Components.BlazorLogger[0]
      TimeStamp: 8/23/2021 12:20:46 PM
      MachineName: ECS-A399
      AppDomainName: BootstrapBlazor.Server
      OS: Microsoft Windows 10.0.17763
      OSArchitecture: X64
      ProcessArchitecture: X64
      Framework: .NET 5.0.9
      UserName: Argo
      EnvironmentName: Development
      IISRootPath: D:\Argo\src\BB\BootstrapBlazor\src\BootstrapBlazor.Server\
      VSIDE: Microsoft Visual Studio Enterprise 2019 16.0
      Exception:: Attempted to divide by zero.
      System.DivideByZeroException: Attempted to divide by zero.
         at BootstrapBlazor.Shared.Pages.GlobalException.OnClick() in D:\Argo\src\BB\BootstrapBlazor\src\BootstrapBlazor.Shared\Pages\GlobalException.razor.cs:line 30

5. Controls whether error details are displayed

Through the configuration file appsettings.json, which is appsettings.Development.json in the development environment, if not set, it defaults to false and is not displayed. The default behavior is only a pop-up prompt to prevent the exposure of sensitive information
    "DetailedErrors": true

This function is to obtain the component instance through the cascade parameter and use its function


In this example code, an error code that divides by zero is written. Because try/catch is used to capture the exception, the error message is displayed in the console below

Set custom exception handling logic by setting OnErrorHandleAsync callback method

Seems like the connection with the server has been lost. It can be due to poor or broken network. Please hang on while we're trying to reconnect...
Oh snap! Failed to reconnect with the server. This is typically caused by a longer network outage, or if the server has been taken down. You can try to reconnect, but if that does not work, you need to reload the page.
Oh man! The server rejected the attempt to reconnect. The only option now is to reload the page, but be prepared that it won't work, since this is typically caused by a failure on the server.
