2. 查看路由（方便进行功能的实现）

mix  phx.routes参考：Generated hello app
page_path  GET     /                   Hello.PageController :index
page_path  GET     /index/:name        Hello.PageController :appdemo
user_path  GET     /user/:name         Hello.UserController :index
demo_path  GET     /api/demo           Hello.DemoController :index
demo_path  GET     /api/demo           Hello.DemoController :index
demo_path  GET     /api/demo/:id/edit  Hello.DemoController :edit
demo_path  GET     /api/demo/new       Hello.DemoController :new
demo_path  GET     /api/demo/:id       Hello.DemoController :show
demo_path  POST    /api/demo           Hello.DemoController :create
demo_path  PATCH   /api/demo/:id       Hello.DemoController :updatePUT     /api/demo/:id       Hello.DemoController :update
demo_path  DELETE  /api/demo/:id       Hello.DemoController :delete

3. 生成脚手架代码 (phx.gen 开头的)

mix phx.gen.json Accounts User users --table cms_users

4. 生产环境构建

phoenix 依赖mix deps.get --only prod
MIX_ENV=prod mix compile资源（web）brunch build --production （构建）
mix phx.digest （压缩）启动PORT=4001 MIX_ENV=prod mix phx.serverorPORT=4001 MIX_ENV=prod iex -S mix phx.serveror 守护进程模式MIX_ENV=prod PORT=4001 elixir --detached -S mix do compile, phx.server

5. 几个问题

因为新版phoenix 脚手架创建web 的目录已经调整到了lib目录 <app>_web 命名，使用旧版本的代码可能需要调整

如下图:

v1.3 之前的

v1.3 以及最新版本
