【问题描述】:
我有这个应用程序,我制作了一个动画背景,当我在 chrome 中打开 HTML 时效果很好,但是当我用烧瓶运行它时,它不会添加背景,只是忽略它 这可能是我错过的东西,但我仍然不明白为什么它不加载背景

Python:
from flask import Flask, render_template, request
def create_app():
app = Flask(__name__)
@app.route('/', methods=['POST', 'GET'])
def home():
return render_template("base.html")
return app
【问题讨论】:
-
你为什么要在函数中声明
app = Flask(__name__)。这就是你所有的python代码?? -
我在其他文件上运行它,但这不是问题@Kunal Tanwar
-
您能否也发布您的文件夹结构的图像?还有整个python代码??
