❔ CallWebApiForUserAsync

I'm doing

List<T>.ForEach(i => { 
  _downstreamWebApi.CallWebApiForUserAsync(
    SERVICE,
    options => {
        options.RelativePath = i

List<T>.ForEach(i => { 
  _downstreamWebApi.CallWebApiForUserAsync(
    SERVICE,
    options => {
        options.RelativePath = i

but for some reason it isn't calling the api not even once. How do you go about calling the api with a list?

On that matter, what does this function do when using <TInput, TOutput> ? https://learn.microsoft.com/en-us/dotnet/api/microsoft.identity.web.idownstreamwebapi.callwebapiforuserasync?view=azure-dotnet

You're not awaiting your async calls

            Urls.ForEach(async i =>
            {
                var r = await _downstreamWebApi.CallWebApiForUserAsync(
                SERVICE,
                options =>
                {
                    options.HttpMethod = HttpMethod.Post;
                    options.RelativePath = i;
                });            
                var obj3 = await JsonSerializer.DeserializeAsync<RazorApp.Models.Entities.EntityList>(await r.Content.ReadAsStreamAsync(), options);
                t3 += await r.Content.ReadAsStringAsync();
            });       

            ViewData["t3"] = t3;

            Urls.ForEach(async i =>
            {
                var r = await _downstreamWebApi.CallWebApiForUserAsync(
                SERVICE,
                options =>
                {
                    options.HttpMethod = HttpMethod.Post;
                    options.RelativePath = i;
                });            
                var obj3 = await JsonSerializer.DeserializeAsync<RazorApp.Models.Entities.EntityList>(await r.Content.ReadAsStreamAsync(), options);
                t3 += await r.Content.ReadAsStringAsync();
            });       

            ViewData["t3"] = t3;

I'd just use a normal foreach loop instead of trying to Javascript it with .ForEach()

Messiah•2y ago

the way I'm dumping the results into a string, then to the view model is ok?

Angius•2y ago

You don't seem to have a viewmodel

Messiah•2y ago

it worked with the normal foreach! jesus christ I spent 26 hours (literally) on this problem this is the viewmodel, it's razor pages why was it not working with .foreach?

Angius•2y ago

Ah, I saw ViewData and thought you're using that as some demented replacement for a viewmodel ¯\_(ツ)_/¯ Dunno, I never really use it, so don't know its quirks Probably because there's async code in the lambda you pass, but .ForEach() itself is a void method

Messiah•2y ago

I see, so the compiler just moves on because it knows it won't be returning anything anyways

Angius•2y ago

yep
