Flask-蓝图

1、使用步骤：

创建蓝图

blue = Blueprint("myblue01", __name__)

使用蓝图装饰视图函数

@blue.route('/')
def index():
    return 'index'

将蓝图注册到app中

from appdemo_blueprint import blue
app.register_blueprint(blue)

2、以包的形式使用蓝图

 <1>user包之__init__.py：

from flask import Blueprint

userBlueprint = Blueprint('user', __name__)

from user import views

<2>user包之views.py:

from user import userBlueprint

@userBlueprint.route('/user')
def user_fun():
    return 'user'

<3>appdemo.py：

from flask import Flask
from user import userBlueprint

app = Flask(__name__)
app.register_blueprint(userBlueprint)

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