About
Microsoft.Extensions.Http package provides AddHttpClient
extension methods for IServiceCollection
, IHttpClientFactory
interface and its default implementation. This provides the ability to set up named HttpClient
configurations in a DI container and later retrieve them via an injected IHttpClientFactory
instance.
Key Features
- The package allows to fluently set up multiple
HttpClient
configurations for applications that use DI viaAddHttpClient
extension method. HttpClientFactory
cachesHttpMessageHandler
instances per configuration name, which allows to reuse resources betweenHttpClient
instances to avoid port exhaustion.HttpClientFactory
manages lifetime ofHttpMessageHandler
instances and recycles connections to track DNS changes.
How to Use
Note that lifetime management of HttpClient
instances created by HttpClientFactory
is completely different from instances created manually. The strategies are to use either short-lived clients created by HttpClientFactory
or long-lived clients with PooledConnectionLifetime
set up. For more information, see the HttpClient lifetime management section in the conceptual docs and Guidelines for using HTTP clients.
Configuring HttpClient
builder.Services.AddHttpClient("foo"); // adding an HttpClient named "foo" with a default configuration
builder.Services.AddHttpClient("example", c => c.BaseAddress = new Uri("https://www.example.com")) // configuring HttpClient itself
.AddHttpMessageHandler<MyAuthHandler>() // adding additional delegating handlers to form a message handler chain
.ConfigurePrimaryHttpMessageHandler(b => new HttpClientHandler() { AllowAutoRedirect = false }) // configuring primary handler
.SetHandlerLifetime(TimeSpan.FromMinutes(30)); // changing the handler recycling interval
Using the configured HttpClient
public class MyService
{
public MyService(IHttpClientFactory httpClientFactory)
{
_httpClientFactory = httpClientFactory; // injecting the factory
}
private Task<string> GetExampleAsync(Uri uri, CancellationToken ct)
{
HttpClient exampleClient = _httpClientFactory.CreateClient("example"); // creating the client for the specified name
return exampleClient.GetStringAsync(uri, ct); // using the client
}
}

Microsoft.Extensions.Http.Polly
The HttpClient factory is a pattern for configuring and retrieving named HttpClients in a composable way. This package integrates IHttpClientFactory with the Polly library, to add transient-fault-handling and resiliency through fluent policies such as Retry, Circuit Breaker, Timeout, Bulkhead Isolation, and Fallback. This package was built from the source code at https://github.com/dotnet/aspnetcore/tree/af22effae4069a5dfb9b0735859de48820104f5b |
