phoenix-framework - 如何获取 URL 的 #fragment 标识符部分

Question

在 Phoenixframework 中，我想知道请求的完整 URL 路径，因此我尝试使用 <%= @conn.request_path %> .
问题是我要求:/spa.html#pageone而我只有 /spa.html .
获得 #fragment 的正确方法是什么？标识符的一部分呢？

该片段在服务器端不可用。
来自 RFC2396

When a URI reference is used to perform a retrieval action on the identified resource, the optional fragment identifier, separated from the URI by a crosshatch ("#") character, consists of additional reference information to be interpreted by the user agent after the retrieval action has been successfully completed. As such, it is not part of a URI, but is often used in conjunction with a URI.

您可以通过 window.location.hash 在 JavaScript 中访问它.
