Python 从其他文件删除路由器

我现在构建的应用程序如下所示

myserver
- server.py
- myapp
-- urls.py
-- models.py
-- views.py
-- consts.py

我的密码在这里

server.py

from flask import Flask
from flask_sqlalchemy import SQLAlchemy

# Flask App
application = Flask(__name__)

# SQLAlchemy
application.config['SQLALCHEMY_DATABASE_URI'] = "sqlite:./local.db"
db = SQLAlchemy(application)

if __name__ == "__main__":
    application.run(debug=True)

from server import application
from . import views

@application.route('/')
def version():
    return views.version()

url.py

from flask import Flask
from flask_sqlalchemy import SQLAlchemy

# Flask App
application = Flask(__name__)

# SQLAlchemy
application.config['SQLALCHEMY_DATABASE_URI'] = "sqlite:./local.db"
db = SQLAlchemy(application)

if __name__ == "__main__":
    application.run(debug=True)

from server import application
from . import views

@application.route('/')
def version():
    return views.version()

但当我运行server.py并打开服务器时，服务器会显示

404notfound

所以我搜索了stackoverflow，找到了一些关于

Blueprint

的描述。我将blueprint命名为app，比如

app=blueprint（'app'，name.\uuuu）

，并从server.py注册它，但我得到了

AttributeError:module'url'没有属性'app'

---

如何在其他文件中定义url路由器？

这里是带有

蓝图的示例。文件结构：

/project_folder
   server.py
   urls.py
   urls2.py

server.py：

from flask import Flask
from urls import urls_blueprint
from urls2 import urls2_blueprint


app = Flask(__name__)
# register routes from urls
app.register_blueprint(urls_blueprint)
# we can register routes with specific prefix
app.register_blueprint(urls2_blueprint, url_prefix='/urls2')

if __name__ == "__main__":
    app.run(debug=True)

URL.py：

from flask import Blueprint

urls_blueprint = Blueprint('urls', __name__,)


@urls_blueprint.route('/')
def index():
    return 'urls index route'

urls2.py：

from flask import Blueprint
urls2_blueprint = Blueprint('urls2', __name__,)


@urls2_blueprint.route('/')
def index():
    return 'urls2 index route'

运行服务器并打开
http://localhost:5000/
和
http://localhost:5000/urls2/

希望这有帮助。
您正在调用“app”，但python不知道什么是“app”。您是否忘记为“应用程序”添加导入？你能发布更新的代码吗？@FuzzyAmi我也从myapp导入URL和注册blueprint URL在
server.py
中添加了这一行。appMy问题与blueprint无关，但感谢您的回答：）
