初始化工程

$ egg-init

选择 Simple

$ npm i
$ npm run dev

浏览器访问 http://localhost:7001 此时服务已经建立

设计API

egg Rest API 接口规范

| Method | URL | File path | Controller name | | - | - | - | - | | GET | /api/{objects}[?per_page={per_page}&page] | app/controller/{objects}.js | index() | | GET | /api/{objects}/:id | app/controller/{objects}.js | show() | | POST | /api/{objects} | app/controller/{objects}.js | create() | | PUT | /api/{objects}/:id | app/controller/{objects}.js | update() | | DELETE | /api/{objects}/:id[s] | app/controller/{objects}.js | destroy() |

数据格式

{
"meta":{"total":3},
"data":[
{"_id":"58d8a899f5f2486f1f6d4236","uid":1,"name":"admin","pass":"123","status":1,"time":"1325472736"},
{"_id":"58db7828a14b14815447cf33","name":"sdf","pass":"123","status":1,"time":"1325472736","uid":3,"__v":0},
{"_id":"58db7d3bcee4d48df6f5bdfd","name":"sdddf","pass":"123","status":1,"time":"1325472736","uid":4,"__v":0}
]
}

api/users/1 GET Single Data

{
"meta":{"total":1},
"data":[
{"_id":"58d8a899f5f2486f1f6d4236","uid":1,"name":"admin","pass":"123","status":1,"time":"1325472736"}
]
}

api/users/2 PUT Update data with uid

{"name":"admin123","pass":"123","status":1,"time":"1325472736"}

api/users POST insert data

{"name":"admin123","pass":"123","status":1,"time":"1325472736"}

数据模型

此处先定义用户 User 对象，在 app 目录下新建 model 文件夹，然后创建 users.js 文件。

每一个 User 对象需要包含用户名、密码、邮箱、公司等信息， users.js 文件内容如下：

// app/model/user.js

module.exports = app => {
  const mongoose = app.mongoose;
  const UserSchema = new mongoose.Schema({
    email : {type: String, required: true},
    password: {type: String, required: true},
    realname: { type:String },
    sex: { type: String },
    corp: { type: String },
    position: { type: String },
    mobile: { type: String },
    region: { type: String },
    qq: { type: String },
    wechat: { type: String },
    bcardurl: { type: String },
    bcardstate: { type: String }
  });

  UserSchema.methods.encryptPassword = function(password) {
    return bcrypt.hashSync(password, bcrypt.genSaltSync(5), null);
  };

  UserSchema.methods.validPassword = function(password) {
    return bcrypt.compareSync(password, this.password);
  };

  return mongoose.model('User', UserSchema);
}
