docker - Traefik 路径中的服务不会重定向到服务路径以获取其他请求

Question

我有一个带有子域的虚拟机 - 例如mysubdomain.notmydomain.com，如下面的日志所示——运行单节点 Docker Swarm(为简单起见)并使用 Traefik 作为各种服务的反向代理。我设法将不同服务的问题简化为我现在在这里分享的问题。
预期行为:我访问了 mysubdomain.notmydomain.com/test，我看到了带有文本和渲染 Logo 的响应。
实际行为::我看到一个断开的链接(见图)

日志显示前几个请求包含 Path:/test而最后一个包含 Path:/ .我认为这就是问题所在。
问题:我需要如何或什么重新配置才能在 tutum/hello-world 上获得辅助请求包含 logo.png 的容器是否正确加载？ tutum/hello-world选择图像进行测试并作为一个明显的例子；实际堆栈包含 mosquitto、grafana、influxdb 和一些自定义服务，它们都显示相同的根行为。 (那些有frontend.rule的)`
任何建议表示赞赏；我可以在需要时提供更多信息。

Thanks for your interest in Træfik!

It's not an issue. Træfik does not rewrite the response body. We think that the process of rewriting the response body in a reverse proxy is too heavy/prone to errors.

We encourage you to either:

• use host based rules only (seems impossible for your use case)
• use specific Traefik path rewrite headers in you app (X-Forwarded-Prefix, X-Replaced-Path)
• let your app listen on a specific path
