烧瓶分类给404个错误的应用程序
我正在浏览此文档： https://flask-classful.teracy.org/
上面文档的应用。
from flask import Flask
from flask_classful import FlaskView
# we'll make a list to hold some quotes for our app
quotes = [
"A noble spirit embiggens the smallest man! ~ Jebediah Springfield",
"If there is a way to do it better... find it. ~ Thomas Edison",
"No one knows what he can do till he tries. ~ Publilius Syrus"
]
app = Flask(__name__)
class QuotesView(FlaskView):
@app.route("/")
def index(self):
return "<br>".join(quotes)
QuotesView.register(app)
if __name__ == '__main__':
app.run()
当我运行此应用程序时，它给出了404个错误。
(venv) C:\fifa\web_app_flask_bootstrap>python app.py
* Serving Flask app 'app' (lazy loading)

127.0.0.1 - - [28/Jun/2022 13:44:56] "GET / HTTP/1.1" 404 -
我已经安装了以下瓶相关软件包：
Flask==2.1.2
Flask-Classful==0.14.2
Python version: 3.9.2
显示该错误的原因是什么？
试验1： 更改了端口并尝试了。 app.run（port = 5001）获得相同的错误。
I am going through this document: https://flask-classful.teracy.org/
Copied minimal app from above document.
from flask import Flask
from flask_classful import FlaskView
# we'll make a list to hold some quotes for our app
quotes = [
"A noble spirit embiggens the smallest man! ~ Jebediah Springfield",
"If there is a way to do it better... find it. ~ Thomas Edison",
"No one knows what he can do till he tries. ~ Publilius Syrus"
]
app = Flask(__name__)
class QuotesView(FlaskView):
@app.route("/")
def index(self):
return "<br>".join(quotes)
QuotesView.register(app)
if __name__ == '__main__':
app.run()
While I am running this app, it is giving 404 error.

I am having following flask related packages installed:
Flask==2.1.2
Flask-Classful==0.14.2
Python version: 3.9.2
What could be the reason for showing that error?
Trial1:
Changed port and tried. app.run(port=5001) Getting same error.

将这2行更改为：
@app.route（“/”）@route（“/”）quotesview.register（app）到Change this 2 lines to:
@app.route("/")to@route("/")QuotesView.register(app)to您提供的链接中的代码段不包括
index函数之前的decorator@app.route（'//'）。并且，在摘要之后，立即说：运行此应用程序并将您的Web浏览器打开至：http：// localhost：5000/quotes/quotes/。我不知道
flask-classful有效，但我想它以类的名称并将其用作端点（在此示例中，quotesview查看并将其制作小写）。但是，这是一个猜测。The code snippet in the link that you provided doesn't include the decorator
@app.route('/')before theindexfunction. And, immediately after the snippet, it say:Run this app and open your web browser to: http://localhost:5000/quotes/.I don't know how
Flask-Classfulworks but I guess that it takes the name of the class and use it as endpoint (in this example,QuotesView, take all beforeViewand make it lowercase). But, again, it's a guess.
