flask-蓝图blueprint按功能块分开()

随着业务逻辑 的增多.视图函数不能都直接写在flask入口文件app.py中
需要按功能块将视图函数分别写到blueprint目录下单独的py文件中.
然后在app.py中对每个Blueprint对象进行注册.

# app.py
from blueprints.demo import bp as demobp
from blueprints.auth import bp as authbp
from blueprints.qa import bp as qabp

app=Flask(__name__)
app.register_blueprint(demobp)  #绑定
app.register_blueprint(authbp)
app.register_blueprint(qabp)

# blueprints/demo.py
from flask import  Blueprint,render_template
bp = Blueprint('demo', __name__, url_prefix='/demo') #

@bp.route('/')
def curr_demo():
    session['uname']='Yancy'
    return render_template('template-demo2.html')
....

http://127.0.0.1:5000/demo/

# blueprints/auth.py
from flask import  Blueprint,render_template
bp = Blueprint('auth', __name__, url_prefix='/auth')

@bp.route('/login')
def login():
    return render_template('login.html')

@bp.route('/resigter')
def register():
	return render_template('register.html')
....

http://127.0.0.1:5000/auth/login
