在 Windows 10 的 HTTP.SYS 和 IIS 中禁用 HTTP/2/SPDY [英] Disabling HTTP/2 / SPDY in HTTP.SYS and IIS in Windows 10
问题描述
在 Windows 10 上进行测试时，我们发现许多浏览器不兼容问题，这是我以前从未见过的早期 Windows 版本.一些浏览器可以工作，但其他浏览器会报告 ERR_SPDY_PROTOCOL_ERROR.我对这个问题的快速搜索表明我并不孤单.
When testing on Windows 10 we were seeing lots of browser incompatibilities that I hadn't seen before with earlier Windows versions. Some browsers would work, but others would report ERR_SPDY_PROTOCOL_ERROR. My quick search for this problem showed I was not alone.
我的应用使用带有 HTTPS (TLS) 的 WWSAPI 和 HTTP.SYS.有谁知道如何在 Windows 10 上禁用 WWSAPI(使用 HTTP.SYS)中的 SPDY/HTTP/2?
My app uses WWSAPI and HTTP.SYS with HTTPS (TLS). Does anyone know how to disable SPDY / HTTP/2 in WWSAPI (which is using HTTP.SYS) on Windows 10?
我还希望获得完整的最新 Windows 10 HTTP.SYS 注册表设置列表.
I'd also love to get a full up-to-date Windows 10 list of registry settings for HTTP.SYS.
请看下面我对此的回答.希望这对其他人也有帮助.

推荐答案
禁用 HTTP/2 会显着降低您网站的速度，这不是永久的解决方案.问题原来是我们的 webapp 向服务器发送了错误的身份验证标头引起的.
disabling HTTP/2 will significantly slow down the speed of your website, this is not a permanent solution. The problem turned out to be caused by our webapp sending a wrong authentication header to the server.
要仍然禁用 HTTP/2，请参见下文.
To still disable HTTP/2, see below.
(OP给出了一个有用的答案，但在问题中.我移动了答案):
(OP gave a helpful answer, but in the question. I moved the answer):
我确实通过配置 Windows 10 HTTP.SYS 解决了我的 HTTP/2 问题在注册表中禁用 HTTP/2.鉴于我没有找到信息在任何地方，我想我也会在这里分享我对这个问题的解决方案.一世不过想通过 WWSAPI 找到一种方法.
I did work around my HTTP/2 problem by configuring Windows 10 HTTP.SYS in the registry to disable HTTP/2. Given that I didn't find info anywhere, I thought I'd share my solution to that problem here too. I would like to find a way of doing this through WWSAPI though.
如果我在客户端浏览器中关闭 SPDY 支持，它会起作用，但是我想在服务器端关闭它(Windows 10 上的 HTTP.SYS)这样它就不会协商 HTTP/2，而是使用较旧的更多兼容 HTTP(S).
If I turned off SPDY support in the client browser, it would work but I wanted to turn this off at the server side (HTTP.SYS on Windows 10) so that it wouldn't negotiate HTTP/2 but would use the older more compatible HTTP(S).
在以下位置发现了 HTTP.SYS 的两个新注册表设置:
Discovered two new registry settings for HTTP.SYS in:
HKEY_LOCAL_MACHINESystemCurrentControlSetServicesHTTPParameters
EnableHttp2TlsREG_DWORD0EnableHttp2CleartextREG_DWORD0
在 Windows 10 中添加这些值并将两者都设置为 0 会导致HTTP/2/SPDY 未协商，我的 ERR_SPDY_PROTOCOL_ERROR无需更改浏览器配置即可解决问题.我并不是说 Windows 10 HTTP/2 有什么问题，某些浏览器可能存在问题.
Adding these values and setting both to 0 in Windows 10 resulted in HTTP/2 / SPDY not being negotiated and my ERR_SPDY_PROTOCOL_ERROR problems went away without requiring browser configuration changes. I'm not suggesting there is anything wrong with Windows 10 HTTP/2, the problems may be with certain browsers.
这可能也适用于 IIS，但我不使用它，所以我没有尝试过无论如何，在 IIS 中可能有更好的方法来做到这一点.
This may work for IIS too, but I don't use that so I haven't tried and in any case there may be a better way to do this in IIS.

我可以确认这对 IIS 也有帮助，但我必须重新启动计算机.
I can confirm this helps for IIS too, but I had to restart my computer.
