ssl - IIS 10 和 HTTP/2 - 需要客户端证书

Question

目前，我正在使用 HTTP 1.1 和 HTTP/2 在 IIS 10 上测试 Web 应用程序。 我的测试应用程序有一个端点 (/api/test)，它只返回“true”。 我有 3 个证书:

• 根 CA(自签名)
• 由根 CA 签署的服务器证书
• 由根 CA 签署的客户端证书

安装在 Windows Server 2016 上的根 CA 和服务器证书，以及为监听配置的 IIS 网站 https://example.net:8081/使用服务器证书。此外，我将网站配置为需要客户端证书(这对我的测试很重要，我需要服务器/客户端证书验证)。

我通过 curl 测试我的应用程序，对于 http1.1 一切正常。

命令:

curl.exe --http1.1 --get --url https://example.net:8081/api/test --cacert E:\ca.pem --cert E:\client.pem --key E:\client.key --cert-type PEM --verbose

输出:

* TCP_NODELAY set
* Connected to example.net port 8081 (#0)
* ALPN, offering http/1.1
* successfully set certificate verify locations:
*   CAfile: E:\ca.pem

但是如果我尝试使用 http/2 发送请求，则在服务器证书验证后失败。

命令:

curl.exe --http2 --get --url https://example.net:8081/api/test --cacert E:\ca.pem --cert E:\client.pem --key E:\client.key --cert-type PEM --verbose

输出:

在 IIS 日志中我看到下一条记录:

2018-09-18 13:46:00 172.32.0.193 GET /api/test - 8081 - 134.17.25.89 HTTP/1.1 curl/7.61.1 - 200 0 0 421
2018-09-18 13:55:01 172.32.0.193 GET /api/test - 8081 - 134.17.25.89 HTTP/2.0 curl/7.61.1 - 403 7 64 0

因此，对于 http/2，似乎缺少客户端证书(403.7 状态代码)。

最后，如果我只是将 IIS 站点设置中的“需要客户端证书”更改为“忽略客户端证书”——http1.1 和 http/2 都可以。

如何在 IIS 上将客户端证书与 HTTP/2 一起使用？

Answer 1

经过几个小时的研究，我发现 IIS 10 目前不支持带客户端证书验证的 HTTP/2。

https://learn.microsoft.com/en-us/iis/get-started/whats-new-in-iis-10/http2-on-iis#when-is-http2-not-supported

In a few cases, HTTP/2 can't be used in combination with other features. In these situations, Windows will fall back to HTTP/1.1 and continue the transaction. This may involve negotiating HTTP/1.1 during the handshake, or sending an error code to the client instructing it to retry over an HTTP/1.1 connection.

我正在重新配置我的服务器以使用 nginx 而不是 IIS 作为应用程序的代理，并且一切正常。
