Django+Vue实现前后端交互_代码007(未授权)

本文介绍: 2、创建 vue 项目，执行 npm init vue@la test，可参考 https://cn.vue js.org/guide/quick–start.html#creating-a-vue–application。3、下载 element–plus，npm install element–plus —s av e。3、请求 http://ip:p o rt/#/test，启动前端服务是会显示 ip:p o rt。1、下载安装 node.js，下载地址 https://nodejs.org/en。

Django 环境准备
1、下载 django，执行命令 pip install django
2、新建 django 项目，执行命令 django–admin start project my test（项目名称），以上命令会在当前目录下创建一个名为my test的Django 项目
3、运行 django 项目，执行命令 python manage.py run server
4、下载ninja，执行命令 pip install django-ninja

Django 跨域配置
1、执行命令 pip install django–cors–headers
2、在settings.py中
（1）INSTALLED_APPS里添加“co rs headers”
（2）MIDDLEWARE里添加‘co rs headers.middleware.Co rsMid dl e war e‘
（3）增加CORS_ORIGIN_ALLOW_ALL=Tr ue

Vue 环境准备
1、下载安装 node.js，下载地址 https://nodejs.o r g/en
2、创建 vue 项目，执行 npm init vue@latest，可参考 https://cn.vue js.o r g/guide/quick–start.html#creating-a-vue–application

"""proinit URL Configuration

The `urlpatterns` list routes URLs to views. For more information please see:
    https://docs.djangoproject.com/en/3.2/topics/http/urls/
Examples:
Function views
    1. Add an import:  from my_app import views
    2. Add a URL to urlpatterns:  path('', views.home, name='home')
Class-based views
    1. Add an import:  from other_app.views import Home
    2. Add a URL to urlpatterns:  path('', Home.as_view(), name='home')
Including another URLconf
    1. Import the include() function: from django.urls import include, path
    2. Add a URL to urlpatterns:  path('blog/', include('blog.urls'))
