Flask在Python中找不到文件夹和文件 [英] Flask is not finding folders and files in Python
问题描述
我的文件结构如下
>code.py
>模板
....>css
....>index.html
我的烧瓶代码是
从烧瓶导入烧瓶中的 ，url_for从烧瓶导入render_templateapp = Flask(__ name__)@ app.route('/')def index():返回render_template('index.html')如果__name__ =="__main__":app.run() 我的HTML代码是
<！DOCTYPE html>< html lang ="zh-CN">< head>< meta charset ="UTF-8">< meta name ="viewport" content ="width = device-width，initial-scale = 1.0">< title>标题</title>< link rel ="stylesheet" href ="/css/style.css"></head><身体>< header>< img class ="resize" src ="./pictures/apptek_logo.png" alt ="apptek_logo">< nav>< ul class ="nav-links">< li class ="active">< a href ="./index.html"> Home</a></li>< li>< a href ="./contact.html"> Contact</a></li></ul>< script src ="https://code.jquery.com/jquery-3.5.0.js"></script>< script type ="text/javascript">$(document).on('click'，'ul li'，function(){$(this).addClass('active').siblings().removeClass('active')})</script></nav></header></body></html> 由于某种原因，它根本没有加载CSS文件和任何其他html文件.我需要在Flask中做些什么吗?
Flask会在您的项目根目录的以下目录中自动查找CSS，JS和其他静态文件:
/static Flask文档中的更多详细信息，此处.
优良作法是将静态文件分成子目录，如下所示:
/static/css/静态/js 在您的示例中，将CSS放在以下路径:
/static/css/style.css 然后在您的HTML中进行引用:
< link rel ="stylesheet" href ="/static/css/style.css"> 如果您使用的是Jinja2模板，则可以按照文档中的说明进行操作:
{{url_for('static'，filename ='style.css')}} My files structure is following
> code.py
> templates
....> css
....> index.html
and my flask code is
from flask import Flask, url_for
from flask import render_template
app = Flask(__name__)
@app.route('/')
def index():
return render_template('index.html')
if __name__ == "__main__":
app.run()
and my HTML code is
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Title</title>
<link rel="stylesheet" href="/css/style.css">
</head>
<body>
<header>
<img class="resize" src="./pictures/apptek_logo.png" alt="apptek_logo">
<nav>
<ul class="nav-links">
<li class="active"><a href="./index.html">Home</a></li>
<li><a href="./contact.html">Contact</a></li>
</ul>
<script src="https://code.jquery.com/jquery-3.5.0.js"></script>
<script type="text/javascript">
$(document).on('click', 'ul li', function(){
$(this).addClass('active').siblings().removeClass('active')
})
</script>
</nav>
</header>
</body>
</html>
For some reason, it's not loading CSS files, and any other html files at all. Is there anything necessary in Flask I have to do?
Flask automatically looks for CSS, JS and other static files in your project root, in the directory:
/static
More details in the Flask docs here.
It's good practice to seperate your static files into subdirectories, like so:
/static/css
/static/js
In your example, place your CSS at the path:
/static/css/style.css
Then reference as so in your HTML:
<link rel="stylesheet" href="/static/css/style.css">
If you're using Jinja2 templates, you can do as described in the documentation:
{{ url_for('static', filename='style.css') }}
