rest - Http Post 请求导致流结束

Question

我遇到了这个奇怪的问题。我在本地计算机上运行我的应用程序和 Neo4j 服务器。

我在应用程序中发出 POST 请求以在 Neo4j 中开始事务(日志中的第一行):

18/02 13:33:30 DEBUG (http.headers) http-outgoing-0 >> POST /db/data/transaction/ HTTP/1.1

我得到的响应是“流结束”(日志中的最后一行)。

我检查了服务器 http 日志，它没有这个请求(使用 http header 中的 threadUUID 参数搜索)。因此，我没有收到此请求的任何交易。

我无法弄清楚这个“流结束”是什么以及它的原因是什么？

另外，我可以看到一些超时:

18/02 13:34:30 DEBUG (http.wire) http-outgoing-8 << "[read] I/O error: Read timed out"

有什么想法吗？

这正在发生在我们身上。关闭连接然后读取超时似乎是正常的。我还在调查。在我们的情况下更糟，因为在此之后我们有请求将一个请求(正在进行的请求)的 URL 与另一个请求的正文混合在一起，这可能发生在不同的连接、不同的线程和 20 分钟前......

所以这很吓人。
