Global Error Handling
本文内容来自书籍: Marinko Spasojevic - Ultimate ASP.NET Core Web API - From Zero To Six-Figure Backend Developer (2nd edition)
错误处理,一般是使用try-catch
blocks,然后是finally
处理资源释放
但是会把这些处理逻辑零散地分布在代码中,如果将错误处理集中在一块区域,那么业务逻辑中的代码会变得更干净
5.1 Handling Errors Globally with the Built-In Middleware
UseExceptionHandler
中间件是用来处理错误的
- 首先在
Entities
中创建ErrorModel/ErrorDetails
,使用这个实体来包含错误的信息 - 然后在主项目中,注册中间件
Extensions/ExceptionMiddlewareExtensions
public static class ExceptionMiddlewareExtensions
{
public static void ConfigureExceptionHandler(this WebApplication app, ILoggerManager logger)
{
app.UseExceptionHandler(appError =>
{
appError.Run(async context =>
{
context.Response.StatusCode = (int)HttpStatusCode.InternalServerError;
context.Response.ContentType = "application/json";
var contextFeature = context.Features.Get<IExceptionHandlerFeature>();
if (contextFeature != null)
{
logger.LogError($"Something went wrong: {contextFeature.Error}");
await context.Response.WriteAsync(new ErrorDetails()
{
StatusCode = context.Response.StatusCode,
Message = "Internal Server Error.",
}.ToString());
}
});
});
}
}
