[英]HTTP/2 with .Net Core and Kestrel
I'm trying to setup a Web Server with Kestrel
in ASP.Net Core 3.1
to support HTTP/2
.我正在尝试在
ASP.Net Core 3.1
中使用Kestrel
设置 Web 服务器以支持HTTP/2
。 So this is how I configure Kestrel:所以这就是我配置 Kestrel 的方式:
public class Program
{
public static void Main(string[] args)
{
CreateHostBuilder(args).Build().Run();
}
public static IHostBuilder CreateHostBuilder(string[] args)
{
return Microsoft.Extensions.Hosting.Host.CreateDefaultBuilder(args)
.ConfigureWebHostDefaults(webBuilder =>
{
webBuilder.UseKestrel(options =>
{
options.ListenLocalhost(8080, listenOptions =>
{
listenOptions.Protocols = HttpProtocols.Http2;
});
})
.UseStartup<Startup>();
});
}
}
And this is how I test it by making a request with prior HTTP/2
knowledge in a console application:这就是我通过在控制台应用程序中使用先前的
HTTP/2
知识发出请求来测试它的方式:
class Program
{
static async Task Main(string[] args)
{
AppContext.SetSwitch("System.Net.Http.SocketsHttpHandler.Http2UnencryptedSupport", true);
using var client = new HttpClient
{
BaseAddress = new Uri("http://localhost:8080"),
DefaultRequestVersion = new Version(2, 0)
};
var req = new HttpRequestMessage(HttpMethod.Get, "/");
var res = await client.SendAsync(req);
var version = res.Version;
Console.WriteLine(version);
Console.ReadKey();
}
}
}
Unfortunately, the caller program fails with this exception IOException: The response ended prematurely
:不幸的是,调用程序失败并出现此异常
IOException: The response ended prematurely
:
System.Net.Http.HttpRequestException
HResult=0x80131620
Message=An error occurred while sending the request.

What am I missing here?我在这里想念什么?
looks like there is an issue - https://github.com/dotnet/aspnetcore/issues/27536#issuecomment-731932924 I tried with Http1 worked ok看起来有问题 - https://github.com/dotnet/aspnetcore/issues/27536#issuecomment-731932924我尝试使用 Http1 工作正常
listenOptions.Protocols = HttpProtocols.Http1;
