Post 烧瓶/ShinyProxy中的文件上载

当直接执行应用程序时，通过my Flask应用程序中的form/POST请求上传文件效果良好，但当Shinyproxy托管Flask应用程序时，上传文件失败。我一直跟踪到Shinyproxy没有正确执行表单POST请求：

app.py:

index.html:

在Shinyproxy中通过

Dockerfile

返回相同的，但不包含POST行：

172.17.0.1 - - [23/Dec/2019 14:39:42] "GET / HTTP/1.1" 200 -

有人知道我如何在shinyproxy（或其他）中托管此应用程序吗？我想让并发用户能够上传文件，而不使用相同的docker容器/不相互干扰

谢谢和亲切的问候
