问题描述

大约15分钟后，该错误消息从一个长期待处理的请求中登录到chrome控制台.

That error message logged to the chrome console from a long-pending request after around 15 minutes.

它看起来是客户端错误，因为服务器处理仍然有效.

It looks client-side error because server processing still worked.

有什么伙伴可以让我知道如何解决这个问题的吗?

推荐答案

根据铬源，我认为这意味着间谍侦测超时.

According to the chromium source I think it means that a spdy ping timed out.

...
    {net::ERR_EMPTY_RESPONSE, "http.response.empty"},
    {net::ERR_HTTP2_PING_FAILED, "spdy.ping_failed"},
    {net::ERR_HTTP2_PROTOCOL_ERROR, "spdy.protocol"},
...

Chrome在请求之前和之后发送此类ping.

Chrome sends such pings before and after a request.
