借助蓝图机制，实现红图功能，以便进一步细化web模块

1.建立红图类

# 红图类
class Redprint:
    def __init__(self, name):
        self.name = name
        self.mound = []

    def route(self, rule, **options):
        def decorator(f):
            self.mound.append((f, rule, options))
            return f

        return decorator

    def register(self, bp, url_prefix=None):
        if url_prefix is None:
            url_prefix = '/' + self.name
        for f, rule, options in self.mound:
            endpoint = self.name + '+' + \
                       options.pop("endpoint", f.__name__)
            bp.add_url_rule(url_prefix + rule, endpoint, f, **options)

2.建立红图实例

from app.libs.redprint import Redprint

api = Redprint('test')


@api.route('/')
def index():
    return '<h1>Hello World</h1>'

3.在蓝图上注册红图

from flask import Blueprint
from app.sys.admin.api import temp_test

__author__ = 'ljz'

def create_blueprint_admin():
    bp_admin = Blueprint('admin', __name__)
    
    # 在蓝图上注册红图
    temp_test.api.register(bp_admin)

    return bp_admin

4.测试
