Implement a simple registration interface back-end MVC model architecture

The first step: Add a route to the app.js of the generated express framework, with the following code: VAR API = require ('./routes/api '); App.use ('/api ', API);

Step two:. Create a new api.js instantiation route in routes, with the following code: VAR Express = require (' Express '); var router = Express. Router ();
Const Usercontroller = require (".. /controller/user.js "); Router.post ("/user/register ", usercontroller.register); module.exports = router;

Step three: Refer to the business logic layer in this route (create a new controller folder under the root directory and build a user.js as the logical layer).

Where the code is as follows:

Const USERM = require (".. /model/user.js ");//reference M-layer module

Const CRYPTO = require (' crypto ');//introduction of password-compiling module

Const Reginster = (req,res) = >{

const {Name,password} = req.body;

Userm.findoneuser ({name}, (Reqult) =>{

if (result.length>0) {

Res.json ({

Ret:true,

Data:false

})

}else{

Const HASH = crypto.createhash (' sha256 ');

Hash.update (password);

Userm.saveuser ({

Name

Password:hash.digest (' hex ')

}, () =>{

Res.json ({

Ret:true,

Data:true

})

})

}

})

}

Module.exports = {

Register

}

Because the M layer is introduced in the C layer, the M layer template needs to be created first

Create a model folder in the root directory in which a user.js file is built as the modeling layer, the model layer code is as follows:

Const MONGOOSE = require (".. /utils/database.js ");//Introduction of database Links

Const USER = Mongoose.mode (' User ', {

Name:string,

Password:string

})

Const SAVEUSER = (USERINFO,SUCCCB) = >{

Const USER = new User (userInfo);

User.save (). Then (() =>{

SUCCCB ();

})

}

Const FINDONEUSER = (USERINFO,SUCCCB) =>{

User.find (UserInfo). Then (result) =>{

SUCCCB (result);

})

}

Module.exports = {

Saveuser,

Findoneuser

}

Because database links are used at the model level, reference to the custom database link module

Database link module is to create a Utils folder under the root directory, in this folder to create a database.js file,

Where the code is as follows:

var mongoose =require (' Mongoose ');//need to download Mongoose third-party module first

Mongoose.connect (' Mongodb://127.0.0.1:27017/job ', {usemongoclient:true});

Mongoose. Promise = Global. Promise;

Module.exports = Mongoose;

Today is a bit tired, the code temporarily write so much, and then perfect
