我正在使用flask制作一个网站， HTML 工作正常，网站加载，但由于某种原因，HTML 和 CSS 无法链接:
我使用 url_for Flask 命令，但它仍然不起作用，当我打开网站并检查它时，看起来链接正在工作，但 css、javascript 等文件夹是空的
HTML:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>StoreScan</title>
<link rel="icon" href="{{url_for('static', filename='style/assets/dollars.jpeg')}}">
<link rel="stylesheet" href="{{url_for('static', filename='style/bootstrap/css/bootstrap.min.css')}}">
<link rel="stylesheet" href="{{url_for('static', filename='style/style.css')}}">
<script defer src="{{url_for('static', filename='app/app.js')}}"></script>
{% block head %}{% endblock %}
</head>
<body>
<h1 class="display-1 text-center mt-4">

最佳答案
Flask 找不到您的静态文件夹。它位于哪里？除非您修改了蓝图，否则 Flask 将在主应用程序的同一级别查找 satic 文件夹。
因此，假设您有运行应用程序的 .py 文件 - 在下面的示例中为flask_server.py - 在“web”目录的第一级内，flask 将在同一级别查找静态文件夹 - 相同对于模板文件夹来说是正确的:
希望它适合您。 :)
关于javascript - 无法将 CSS 和 JavaScript 链接到 HTML，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/60467938/
