I get the following error while calling an api in my Blazor application:

User's image

Following is the code where the error is pointing:

User's image

And following is the calling api where request is made:

User's image

What went wrong here? Any suggestions?

Thanks,

Please try using an absolute url such like http(s)://<hostname>/api/employees instead of relative url api/employees.

Please note that if the api is located at a cross domain the server of the api must have CORS functionality.

Thanks for the help.

One more thing, how do I include the base address of AddHttpClient in program.cs file? I'd included the following but its not working.

builder.Services.AddHttpClient<IEmployeeService, EmployeeService>(client =>

{

client.BaseAddress = new Uri("https://localhost:7009/");

});

If you use client-side rendered (CSR) components in Blazor Web Apps or Blazor WebAssembly apps, the following Microsoft document will probably help:

Upload files to a server with client-side rendering (CSR)

"The client project (.Client) of a Blazor Web App must also register an HttpClient for HTTP POST requests to a backend web API controller. Confirm or add the following to the client project's Program file:"

builder.Services.AddScoped(sp => new HttpClient { BaseAddress = new Uri(builder.HostEnvironment.BaseAddress) });
