Static resources
from flask import Flask, render_template
app = Flask(__name__, template_folder="templates", static_folder="static", static_url_path="/static")
# template_folder：指定HTML文件查找目录
# static_folder：指定静态资源存放目录
# static_url_path：HTML中静态资源的标志
# 装饰器形式
# @app.route("/index")
# def index():
# return render_template("index.html")
# 非装饰器形式
def index():
return render_template('index.html')
app.add_url_rule('/index', 'index', index)
if __name__ == '__main__':
app.run()
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
## 引用静态资源的两种方法，推荐第二种
<img src="/static/01.jpg"/>
<img src="{{ url_for('static',filename='01.jpg')}}" />
</body>
</html>
