Microsoft.Extensions.Http
// Register IHttpClientFactory in ConfigureServices method
services.AddHttpClient();
// Inject IHttpClientFactory in the constructor
public class MyController : Controller
{
private readonly IHttpClientFactory _httpClientFactory;
public MyController(IHttpClientFactory httpClientFactory)
{
_httpClientFactory = httpClientFactory;
}
public async Task Index()
{
// Create an HttpClient instance from IHttpClientFactory
var client = _httpClientFactory.CreateClient();
// Make a GET request to a remote API
var response = await client.GetAsync("https://jsonplaceholder.typicode.com/posts");
// Read the response content
string content = await response.Content.ReadAsStringAsync();
// Return the response as JSON
return Content(content, "application/json");
}
}
In this example, we have registered IHttpClientFactory in the ConfigureServices method and injected it in the MyController constructor. We have then created an HttpClient instance using IHttpClientFactory and used it to make a GET request to a remote API. Finally, we have returned the response as JSON.
Overall, IHttpClientFactory simplifies the process of creating and managing HttpClient instances in .NET Core applications and improves performance. public HttpClientWrapperShould(ITestOutputHelper outputHelper)
{
Thread.CurrentPrincipal = new GenericPrincipal(new GenericIdentity("testUser"), new[] { "testRole" });
_httpClientFactory = Application.Services.GetService <IHttpClientfactory>();
_outputHelper = outputHelper;
}
