由于ERR_HTTP2_INADEQUATE_TRANSPORT_SECURITY，ASP.NET Core 3.0应用程序无法在Windows Server 2012 R2上运行 [英] ASP.NET Core 3.0 app not working on Windows Server 2012 R2 due to ERR_HTTP2_INADEQUATE_TRANSPORT_SECURITY

问题描述

我使用了一个正常工作的ASP.NET Core 2.2应用程序，将其升级到3.0，突然该应用程序不再在Windows Server 2012中运行.它包含以下内容:

I took a working ASP.NET Core 2.2 app, upgraded it to 3.0 and suddenly the app no longer works in Windows Server 2012. It comes up with the following:

ERR_HTTP2_INADEQUATE_TRANSPORT_SECURITY

Chrome:

Firefox:

在我不得不选择加入HTTP/2之前，现在似乎是默认值以及HTTP1.1.这里有一个 https://github.com/aspnet/AspNetCore/issues/14350 的帖子，但没有真正的解决方案，这完全令人困惑.

It seems that before I had to opt into HTTP/2 and now its the default along with HTTP1.1. There is a post here https://github.com/aspnet/AspNetCore/issues/14350 but that is totally confusing with no real solution.

我尝试了各种启用/禁用不安全协议的方法，但无济于事.例如

I have tried all sorts of enabling / disabling insecure protocols but to no avail. Such as https://www.admin-enclave.com/de/articles-by-year/11-data-articles/website_articles/articles/exchange_articles/405-resolved-error-err_spdy_inadequate_transport_security-when-using-google-chome-and-owa.html

由于我认为更好的协议套件，因此在Windows 10上运行良好.但是在Fiddler中，我检查了一下，与Kestrel进行谈判的唯一区别是:

Works fine on Windows 10 due to what I assume more better protocol suite. But in Fiddler I checked and the only difference when negotiating with Kestrel is:

最上面的一行是不同的，仅此而已.不知道这是什么，它是一些 GREASE 值.

The top line is different, but that is all. Not sure what is it, it is some GREASE value.

Program.cs:

Program.cs:

    public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
      WebHost.CreateDefaultBuilder(args)
      .UseKestrel(opts => {
        opts.ListenAnyIP(5000);
        opts.ListenAnyIP(5001, listenOpts => {
          listenOpts.UseHttps(new HttpsConnectionAdapterOptions {
            ServerCertificate = new X509Certificate2("certificate-server.pfx", "...")
          });
        });
        opts.Limits.MaxRequestBodySize = null;
      })
      .UseContentRoot(Directory.GetCurrentDirectory())
      .UseStartup<Startup>();
  }

更新

由于@ chris-pratt，我似乎走在正确的轨道上.将证书密码更改为 ECDSA_nistP256 可使Web应用程序正常工作.但是不幸的是，我还在使用证书来签名JWT令牌，现在它被打破了:

Update

Seems I am on the right track thanks to @chris-pratt. Changing the certificate cipher to ECDSA_nistP256 make the web application work. But unfortunately I am using the cert to also sign the JWT tokens, and now that is broken with:

System.NotSupportedException:证书密钥算法不正确支持的.在System.Security.Cryptography.X509Certificates.PublicKey.get_Key()

System.NotSupportedException: The certificate key algorithm is not supported. at System.Security.Cryptography.X509Certificates.PublicKey.get_Key()

签名代码为:

  var privateKey = new X509SecurityKey(new X509Certificate2("certificate-server.pfx", "..."));
  var token = new JwtSecurityToken(
    issuer: "Sentry",
    claims: claims,
    notBefore: DateTime.Now,
    expires: DateTime.Now.AddDays(1),
    signingCredentials: new SigningCredentials(privateKey, SecurityAlgorithms.RsaSha256Signature));

  return new JwtSecurityTokenHandler().WriteToken(token);

我尝试更改 SecurityAlgorithms 枚举，但未成功.

I tried changing the SecurityAlgorithms enum but did not get any success.

推荐答案

Windows 2012 R2不支持HTTP/2允许的密码套件.我假设从Core 3.0开始，默认情况下启用了HTTP/2协议.我通过在kestrel中禁用HTTP/2来解决我的问题，如下所示:

Windows 2012 R2 does not support the cypher suites that are allowed for HTTP/2. I assume that starting with Core 3.0 the HTTP/2 protocol is enabled by default. I solved my problem by disabling HTTP/2 in kestrel as follows:

public static IHostBuilder CreateHostBuilder(string[] args) =>

  Host.CreateDefaultBuilder(args).ConfigureWebHostDefaults(webBuilder =>
  {
      webBuilder.UseKestrel(options =>
      {
        options.Listen(System.Net.IPAddress.Parse(DomainIp), 80);
        options.Listen(System.Net.IPAddress.Parse(DomainIp), 443, l =>
        {
          l.UseHttps(
            DomainCertificateFile,
            DomainCertificatePassword);
          l.Protocols = Microsoft.AspNetCore.Server.Kestrel.Core.HttpProtocols.Http1;
        });
      });
      webBuilder.UseStaticWebAssets();
      webBuilder.UseStartup<Startup>();
   });
