BlazorWebAssembly - CallWebApi not working #17549

Closed oridespavaneli closed 4 years ago

oridespavaneli commented 4 years ago

I try to test the CallWebApi official sample, it’s not working for me.

Sample: AspNetCore.Docs-master\aspnetcore\blazor\common\samples\3.x\BlazorWebAssemblySample System.Net.Http.Json (3.2.0-preview3.20175.8) package used to replace Microsoft.AspNetCore.Blazor.HttpClient package. The required WebApi is up and running, all intructions applied.

Option: Call a Web Api (https://localhost:44365/CallWebApi) When clicked, shows the alert “An unhandled erros has ocorred. Reload”. The page is prepared for sending the request. If you dismiss the alert and click on the button “Request”, i got the following response:

Response Status: RedirectMethod
