我可以使用 SocketHttpHandler 而不是 HttpMessageHandler 吗？

Question

Flurl 默认配置为使用 HttpMessageHandler。但是，我的应用程序使用 .NET Core 3.1，我知道这个框架对新的 SocketHttpHandler class 有更好的支持。那么我可以像这样创建自定义 class 吗？


public class CustomHttpClientFactory : DefaultHttpClientFactory
{
    #region Overrides of DefaultHttpClientFactory

    /// <summary>
    ///     Override in custom factory to customize the creation of HttpClientHandler used in all Flurl HTTP calls.
    ///     In order not to lose Flurl.Http functionality, it is recommended to call base.CreateMessageHandler and
    ///     customize the result.
    /// </summary>
    public override HttpMessageHandler CreateMessageHandler() => new SocketsHttpHandler
    {
        AllowAutoRedirect           = false,
        ConnectTimeout              = TimeSpan.FromMinutes(1),
        PooledConnectionLifetime    = TimeSpan.FromMinutes(1),
        PooledConnectionIdleTimeout = TimeSpan.FromMinutes(1),
        MaxConnectionsPerServer     = 20,
        SslOptions = new SslClientAuthenticationOptions
        {
            AllowRenegotiation                  = false,
            RemoteCertificateValidationCallback = (sender, certificate, chain, errors) => true
        }
    };

    #endregion
}

并在OnStartup

中配置

FlurlHttp.ConfigureClient(AppConstants.ServiceUrl, cli =>
                {
                    cli.BaseUrl = AppConstants.ServiceUrl;

                    cli.Configure(settings =>
                    {
                        settings.ConnectionLeaseTimeout = TimeSpan.FromSeconds(60);
                        settings.Timeout                = TimeSpan.FromSeconds(60);
                        settings.HttpClientFactory      = new CustomHttpClientFactory();
                    }).WithHeaders(headers);
                });

HttpMessageHandler 是一个摘要 class。 Flurl 默认使用的实现是 HttpClientHandler。我猜这就是你想要换成 SocketsHttpHandler.

的东西

幸运的是，.NET 团队也更喜欢后者的实现，这就是 HttpClientHandler now delegates literally all of its work to SocketsHttpHandler.

的原因

换句话说，如果您使用的平台支持 SocketsHttpHandler（.NET Core 2.1 或更高版本），则默认使用它。无需自定义工厂。

也就是说，如果您需要使用一些自定义配置来初始化处理程序，那么我认为您所做的很好。

I can use SocketHttpHandler instead of HttpMessageHandler?
