stark组件前戏之以上知识点整合应用示例

app01/views.py

from django.shortcuts import HttpResponse

# Create your views here.


def index(request):
    return HttpResponse("index")

luffy.py

from django.urls import re_path
from app01 import views

        self._registry = []

    def get_urls(self):

        patterns = []
        # 循环类变量所定义的列表，此时列表已有两个元素，['app01', 'app02']，按照子路由的格式进行拼接并添加到patterns列表中

        return (self.get_urls(), None, None)

app01/xxx.py

from luffy import site

from django.urls import re_path

urlpatterns = [
    re_path(r'^web/', site.urls),  # 调用luffy.py文件中的urls方法
]

启动Django项目，前端输入路由进行查看
