Firefox接收Kvarn Web服务器HTTP/2推送时无响应问题求助

云上老周

2026-10-18

我正在开发一款名为Kvarn的Web服务器，它支持HTTP/2协议，我计划将其打造为HTTP Push领域的领先实现。

目前该服务器已托管了kvarn.org和icelk.dev两个站点，你可以自行访问测试。

发送推送请求的相关代码可查看此处。

最近我遇到了一个问题：我实现的推送功能在Firefox上无法正常工作，看起来推送的资源流没有正常关闭，Firefox开发者工具显示对应资源尚未收到服务器返回的首字节。

我的技术栈为Rust + Tokio，使用H2库实现HTTP/2协议。

该功能在Chromium系浏览器和Safari上完全正常，我记得在早前几个版本的Firefox上也能正常运行，我用Tor Browser测试也能正常工作，这点十分奇怪，因为Tor Browser是基于Firefox构建的。

我找到了另一款支持HTTP Push的站点，是Go语言团队提供的测试站点，它在Firefox上可以正常使用HTTP/2推送功能。

之后我使用nghttp工具对Kvarn进行了测试，测试结果如下：

测试日志看起来没有问题，和Go示例站点的同场景测试返回的数据帧结构完全一致。

之前我提到看起来像是流没有关闭，我也做了验证：在我认为流已经关闭后尝试再次向流写入数据，确实触发了H2库的报错，说明流已经正常关闭。

最后我还使用h2spec工具对实现进行了测试，所有测试项全部通过，而Go的示例站点并没有全部通过测试。

我现在已经找不到可能的问题点了，提前感谢大家提供的任何帮助，非常感激。
