Question

我有一个带有子域的VM - 例如mysubdomain.notmydomain.com，在下面的日志中可见 - 运行单个节点Docker Swarm（为简单起见）并使用Traefik作为各种服务的反向代理。我设法将我的问题简化为现在我在这里分享的不同服务。

预期的行为：我得到mysubdomain.notmydomain.com/test，我看到一个带有文字和渲染徽标的回复。

实际行为：：我看到链接断开（见照片）

日志显示前几个请求包含Path:/test，而最后一个请求包含Path:/。我认为这是出了什么问题。

问题：我需要重新配置如何或者什么才能在包含logo.png的tutum/hello-world容器上正确加载辅助请求？

tutum/hello-world图像正在进行测试并作为一个明显的例子;实际的堆栈包含mosquitto，grafana，Influxdb和一些显示相同root行为的自定义服务。（那些有frontend.rule的）`

任何建议都表示赞赏;我可以在需要时提供更多信息。

来自#3124的Github问题Julien Salleyron：

感谢您对Træfik的兴趣！

这不是问题。 Træfik不会重写响应体。我们认为   在反向代理中重写响应主体的过程是   太重/容易出错。

我们鼓励您：


仅使用基于主机的规则（对于您的用例似乎不可能）

在您的应用中使用特定的Traefik路径重写标题（X-Forwarded-Prefix，X-Replaced-Path）

让您的应用听取特定路径

Traefik路径中的服务不会重定向到服务路径以获取其他请求
