如何使.NET HttpClient的使用http 2.0吗？ [英] How to make the .net HttpClient use http 2.0?

问题描述

我有IIS上承载的10（在Windows Server 2016）一个asp.net网页API。当我把从微软边缘浏览器中的 GET 要求这一点，我看到 HTTP 2.0 在IIS日志使用

I have an asp.net web api hosted on IIS 10 (windows server 2016). When I make a GET request to this from a Microsoft Edge browser, I see that HTTP 2.0 is used in IIS logs

2015-09-20 21:57:59 100.76.48.17 GET /RestController/Native - 443 - 73.181.195.76 HTTP/2.0 Mozilla/5.0+(Windows+NT+10.0;+Win64;+x64)+AppleWebKit/537.36+(KHTML,+like+Gecko)+Chrome/42.0.2311.135+Safari/537.36+Edge/12.10240 - 200 0 0 7299

然而，当 GET 请求通过的。网4.6客户端如下，

using (var client = new HttpClient())
{
    client.BaseAddress = new Uri("https://myapp.cloudapp.net/");

    HttpResponseMessage response = await client.GetAsync("RestController/Native");
    if (response.IsSuccessStatusCode)
    {
        await response.Content.CopyToAsync(new MemoryStream(buffer));
    }
}

我看到下面的 HTTP 1.1 登录服务器日志

2015-09-20 20:57:41 100.76.48.17 GET /RestController/Native - 443 - 131.107.160.196 HTTP/1.1 - - 200 0 0 707

我怎样才能使.NET客户端使用HTTP / 2.0？

How can I make the .net client use HTTP/2.0 ?

推荐答案

的HttpClient 不支持HTTP / 2呢。这将是在下一版本（code名称KATANA）可用。这里是链接到他们的源$ C ​​$ C下一个版本。

HttpClient does not support HTTP/2 yet. It will be available in the next release (code name KATANA). Here is the link to their source code for the next release.

至此，你可以实现自己的 HttpMessageHandler 对象实现HTTP / 2，并把它传递给的HttpClient 的构造函数（你大概可以使用来自KATANA源头code）。

Till then, you could implement your own HttpMessageHandler object that implements HTTP/2 and pass it to the HttpClient's constructor (you probably can use their source code from KATANA).
