auth.py

from flask import Blueprint, render_template


# /auth
bp = Blueprint("auth", __name__, url_prefix="/auth")


# 也就是前面已经定义好前缀，/auth/login
@bp.route("login")
def login():
    pass


@bp.route("register")
def register():
    return render_template("register.html")


# @bp.route("login")

# 导入蓝图
from blueprints.qa import bp as qa_bp

# blueprint，用来做模块化的
# 蓝图，视图函数模块化，蓝图


# 注册蓝图，简化app.py中的文件，便于后期维护
app.register_blueprint(qa_bp)
app.register_blueprint(auth_bp)

    return 'Hello World!'
