Error Handling with Angular 8 – Tips and Best Practices

Handling errors properly is essential in building a robust application in Angular. Error handlers provide an opportunity to present friendly information to the user and collect important data for development. In today’s age of advanced front-end websites, it’s more important than ever to have an effective client-side solution for error handling.

An application that does not handle errors gracefully leaves its users confused and frustrated when the app suddenly breaks without explanation. Handling these errors correctly across an application greatly improves user experience. Collected data from the error handling can inform the development team about important issues that slipped past testing. This is why monitoring tools like Rollbar are so important.

In this article, we will compare several solutions for error handling in Angular apps. First, we will describe the traditional approaches using ErrorHandler and HttpClient. Then, we will show you a better solution using HttpInterceptor. We’ll also show you how to use this interceptor to monitor and track errors centrally in Rollbar.

c# – How to read request body in a asp.net core webapi controller?

 

How to read request body in a asp.net core webapi controller?

A clearer solution, works in ASP.Net Core 2.1 / 3.1

Filter class

using Microsoft.AspNetCore.Authorization;
// For ASP.NET 2.1
using Microsoft.AspNetCore.Http.Internal;
// For ASP.NET 3.1
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc.Filters;

public class ReadableBodyStreamAttribute : AuthorizeAttribute, IAuthorizationFilter
{
public void OnAuthorization(AuthorizationFilterContext context)
{
// For ASP.NET 2.1
// context.HttpContext.Request.EnableRewind();
// For ASP.NET 3.1
// context.HttpContext.Request.EnableBuffering();
}
}

In an Controller

[HttpPost]
[ReadableBodyStream]
public string SomePostMethod()
{
//Note: if you're late and body has already been read, you may need this next line
//Note2: if "Note" is true and Body was read using StreamReader too, then it may be necessary to set "leaveOpen: true" for that stream.
HttpContext.Request.Body.Seek(0, SeekOrigin.Begin);

using (StreamReader stream = new StreamReader(HttpContext.Request.Body))
{
string body = stream.ReadToEnd();
// body = "param=somevalue&param2=someothervalue"
}
}
