理解 Django 交互方法
test1访问接口， 然后直接返回数据 (json)
test2
GET 与 POST 访问 [ 这里只介绍 GET, POST 同理 ]
test3
访问接口, 返回静态网页数据
test4
访问接口，返回动态网页，HTML 专用
test5
访问接口，返回动态网页，JAVASCRIPT 专用
test6
文件下载 (csv)
参考 CSV EXPORT 文档
说明
在使用 DJango 时，除了编写 pytonn 代码以外，还需要注意下面事情
需要配置路由 (
urls.py
) 定义接口
http://x.x.x.x/接口/
pyton 程序 (后端) 与网页程序 (前段) 是相互独立，但也可以配合工作
example
参考文件结构
.
├── demo <- 项目目录
│ ├── __init__.py
│ ├── settings.py
│ ├── urls.py <- 路由文件
│ └── wsgi.py
├── manage.py
├── template <- 动态 html 位置
│ ├── test3.html
│ ├── test4.html
│ └── test5.html
└── tiweb <-- apps
├── __init__.py
├── migrations
│ └── __init__.py
└── views.py <- python 代码
路由配置
工作方式
client -> uwsgi -> urls.py
\--> /test1/
\--> python( 运算 )
uwsgi <---------------------|
参考
urls.py
from django.conf.urls import url
from tiweb import views
urlpatterns = [
url(r'^test1/', views.Demo.test1),
url(r'^test2/', views.Demo.test2),
url(r'^test3/', views.Demo.test3),
url(r'^test4/', views.Demo.test4),
url(r'^test5/', views.Demo.test5),
]
参考代码
