我们最近在 azure 网站和 web API 之间启用了 HTTP2 流量。 这是通过 Azure 门户中的开关启用的。 从 Web 应用到 Web API 的第一个请求失败，并显示：(失败( 网络：：ERR_SPDY_PROTOCOL_ERROR
并且看起来请求从未进入 api。 我们已尝试将这两个应用升级到 .NET 4.6.1，假设旧版本不支持新的 HTTP2 协议。 我正在努力在 chrome 中的开发工具或使用 chrome 中的高级跟踪工具中找到任何有用的东西。 以下是我们在使用高级 Chrome 网络工具 (chrome://net-internals/#events( 检查对 api 的请求的详细 HTTP2 会话事件跟踪时看到的错误：

我觉得网上应该有更多关于如何使您的应用程序使用 http2 进行通信的信息，但我们没有找到任何东西。
任何帮助不胜感激！
谢谢

我还包含了我们正在发出的 HTTP2 请求，该请求是从 chrome 中的 HAR 文件保存的：

这是我切换回 HTTP1 时来自 API 的响应，它响应正确：

错误发生在HTTP_TRANSACTION_READ_HEADERS之后的事实很有趣。
HTTP/2 对 HTTP 标头要严格得多，而 HTTP/1 对无效标头非常宽容。因此，如果您的 HTTP 标头中有冒号或空格，这可能是原因。
通常，您会在chrome://net-internals/#events中看到比显示的信息更多的信息，如果这是原因，这应该有助于查明导致问题的标头。尝试转到chrome://net-internals/#http2，看看您是否获得了更多信息。
有关详细信息，请参阅此博客文章。或者，如果您将HTTP标头(来自HTTP/1请求(添加到问题中，那么我们可能能够发现一些东西。
因此，在尝试了上述所有方法，从标头中删除所有小写字符串，从请求令牌中删除"__"之后，没有任何效果。 我们在防伪请求中连接了两个令牌，并在 API 端将它们拆分出来。 我注意到第二个静态字符串在字符串的末尾有一个"="。 我们从所有应用程序中删除了它，它现在适用于所有 HTTP1 和 2 请求！
感谢您的帮助！检查标题中的字符是我从中学到的。
