How would you handle exceptions in REST APIs?
- Implement global exception handling using middleware to catch unhandled
exceptions.
- Return consistent and meaningful error responses.
- Log errors for debugging and monitoring.
Example in ASP.NET Core:
app.UseExceptionHandler(appError =>
appError.Run(async context =>
context.Response.StatusCode = 500; // Internal Server Error
context.Response.ContentType = "application/json";
var contextFeature =
context.Features.Get<IExceptionHandlerFeature>();
if(contextFeature != null)
// Log exception (use ILogger)
await context.Response.WriteAsync(new
StatusCode = context.Response.StatusCode,
Message = "Internal Server Error.",
Detail = contextFeature.Error.Message
}.ToString());
});
});
