Toolbelt.blazor.httpclientinterceptor: See the message coming from the server

[americanslon]

Is it possible to see the response message coming from the server and if so could to you post an example?

I am trying to use this to have on spot where I place the "error" toast so I need to be able to see when the request returns the error.

Thanks!

One solution is to change the SendAsync method to:

protected override async Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
        {
            HttpResponseMessage response = null;
            try
            {
                BeforeSend?.Invoke(this, request);
                response = await (SendAsyncMethod.Invoke(Handler, new object[] { request, cancellationToken }) as Task<HttpResponseMessage>);
                return response;
            }
            finally
            {
                AfterSend?.Invoke(this, response);
            }
        }

and the eventhandlers to

/// <summary>
/// Occurs before a HTTP request sending.
/// </summary>
public event EventHandler<HttpRequestMessage> BeforeSend;

/// <summary>
/// Occurs after received a response of a HTTP request. (include it wasn't succeeded.)
/// </summary>
public event EventHandler<HttpResponseMessage> AfterSend;

I took this suggestion. Sorta seems that's how it should be in the first place. Makes this interceptor significantly more useful, unless I am not understanding the usefulness of EventArgs e

Thank you for nice feedback! 👍

I published "Blazor WebAssembly (client-side) HttpClient Interceptor" v.6.1.0 that include the new feature suggested by @khamang !

So this should be fixed? I still get an error if I want to access the response content in the AfterSend.
It says in the Service that makes the http.PostAsync cant access the body because it is locked

@TheSwerik Thank you for your reporting.

So this should be fixed? I still get an error ...

This thread is not an error report, this is a new feature proposal thread.
I never knew it has a problem that you reported now.

I'll try to reproduce that problem later, and I'll try to fix it if I could reproduce it.

[TheSwerik]

Oh I thought this fits here, I will create a new and more detailed issue

@TheSwerik Thanks!
