I created a ViewComponent
class which call a REST API
using the HttpClient
, this is the code:
public class ProductsViewComponent : ViewComponent
{
private readonly HttpClient _client;
public ProductsViewComponent(HttpClient client)
{
_client = client ?? throw new ArgumentNullException(nameof(client));
}
public async Task<IViewComponentResult> InvokeAsync(string date)
{
using(var response = await _client.GetAsync($"/product/get_products/{date}"))
{
response.EnsureSuccessStatusCode();
var products = await response.Content.ReadAsAsync<List<Products>>();
return View(products);
}
}
}
I get this error:
InvalidOperationException: Unable to resolve service for type 'System.Net.Http.HttpClient' while attempting to activate MyApp.ViewComponents.ProductsViewComponent'
I injected the HttpClient
in the ConfigureService
method available in Startup
in this way:
services.AddHttpClient<FixturesViewComponent>(options =>
{
options.BaseAddress = new Uri("http://80.350.485.118/api/v2");
});
UPDATE:
I registered the ProductsViewComponent
too, same error.
