azure - 使用 Azure Web 应用程序和 Web api 的 HTTP2 请求

标签 azure azure-web-app-service http2

我们最近在我们的 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 应用程序到 Web api 的第一个请求失败并显示: (失败)net::ERR_SPDY_PROTOCOL_ERROR

并且看起来请求从未发送到 API。 我们尝试将这两个应用程序升级到 .NET 4.6.1，假设旧版本不支持新的 HTTP2 协议(protocol)。 我正在努力寻找 chrome 中的开发工具中有用的东西，或者使用 chrome 中的高级跟踪工具。 以下是我们使用高级 Chrome 网络工具 (chrome://net-internals/#events) 检查 api 请求的详细 HTTP2 session 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信息。

感谢任何帮助!

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:

最佳答案

错误发生在 HTTP_TRANSACTION_READ_HEADERS 之后的事实很有趣。

HTTP/2 对 HTTP header 更加严格，而 HTTP/1 对无效 header 相当宽容。因此，如果您的 HTTP header 中有冒号或空格，这可能就是原因。

通常情况下，您会在 chrome://net-internals/#events 中看到比您显示的更多信息，这应该有助于查明导致问题的 header (如果这是原因)。尝试访问 chrome://net-internals/#http2 查看是否获得更多信息。

参见this blog post了解更多信息。或者，如果您将 HTTP header (来自 HTTP/1 请求)添加到问题中，那么我们也许能够发现一些内容。
