The HttpClientFactory manages scope and lifetime of HTTPClient instances in your application. It also works with the DI Container for managing custom classes that encapsulate the HTTPClient instances.
- [Instructor] The IHttpClientFactory…provides a central location…for configuration and naming of HttpClient instances.…It manages the lifetime and disposal of HttpClient instances…and it supports registration and chaining of handlers.…It also provides support for Polly-based handlers…and generated clients…and it adds logging via the standard…ASP.NET Core ILogger interface.…
The IHttpClientFactory manages the pooling…and lifetime of HttpMessageHandlers…which reduces resource consumption…when using the HttpClient.…It sets a default timeout to two minutes…and it handles disposing of HttpClient instances…and all of their owned resources.…There are four basic consumption patterns,…the basic usage, named clients, typed clients,…and generated clients,…and we will examine all of these in the code samples.…
The basic usage is helpful…when you don't want to refactor an existing code base.…It starts off by adding services.AddHttpClient…into the ConfigureServices…and then you're consuming code,…takes an instance of the IHttpClientFactory…
