使用proxy_pass的Nginx反向代理可用于根位置，但不能用于子目录

Question

几天来我一直在努力，我一直在学习Nginx的工作方式，但是我怕错过了一些非常愚蠢或简单的事情。

我有一个运行在abc.domainname.com:444的docker容器中的webapp。如果我通过该URL访问它，则它的功能非常完善。但是，我不希望URL中需要端口号，因此我一直在尝试将Nginx设置为反向端口，以便在有人访问abc.domainname.com时获得所有内容。 abc.domainname.com:444中的。经过几天的工作，我成功地从URL中获取了端口号以进行直接访问，但是docker应用正在从abc.domainname.com:444/app/dfjsdfksdfjsdkfdsj.js，abc.domainname.com:444/images/images1/fjdskds.jpg等位置加载一些资源/app/和/images/中的其他子目录。当我访问位于abc.domainname.com的站点时，这些资产未加载。根据我的开发者控制台，每个资源都有一个404。每个资源的URL都是正确的-如果指定了端口号，则应该是正确的。

基本上，abc.domainname.com:444/app/dfjsdfksdfjsdkfdsj.js会加载资源，但是使用下面的Nginx配置，我发现似乎只有根正在通过代理传递，因为同一资源不能称为abc.domainname.com/app/dfjsdfksdfjsdkfdsj.js

我什至试图为这些项目建立封锁，但无济于事。

我感觉到我所缺少的位置限制存在问题。有更多经验的人可以帮助我找出我的错误，以便（希望）开始理解Nginx定位块以及Nginx如何用作反向代理。
