当我去
http://127.0.0.1:5000/any_url_not_routed
,如下所示,
它 returns 一个 404 error
正如预期的那样,但是当我在末尾放置一个斜杠时,
http://127.0.0.1:5000/any_url_not_routed/
,如下所示,
它呈现相同的页面但没有 css 和 js。
类似的事情发生在其他页面,如 /register、/login 等。此外,浏览器会在末尾放置自动斜杠。
请告诉我发生了什么事?我可以在这里 link 更多代码。
您的 "css/bootstrap.min.css"
在缺少尾部斜线时导致 "/css/bootstrap.min.css"
,在尾部斜线存在时导致 "/any_url_not_routed/css/bootstrap.min.css"
。
您应该使用绝对路径 "/css/bootstrap.min.css"
来引用资源,就像您已经对 "/register"
.
这样的操作所做的一样
您可以通过查看您服务器的请求日志来核实这件事的真实性。
