  mongoURI: 'mongodb://user:password@ds223542.mlab.com:23542/taxware-api',
  secretOrKey: 'secret'
};

　　

2.node后台上传heroku服务器

首先下载安装heroku-cli工具

https://devcenter.heroku.com/articles/heroku-cli

1.后台代码git到本地仓库

2.命令行中上传代码到heroku服务器 

命令如下:

PS C:UsersAdministratorDesktopjd-interface> heroku login    //命令中登录heroku
heroku: Press any key to open up the browser to login or q to exit:
 »   Warning: If browser does not open, visit
