创建POJO类

export default class TransactionDTO{
    constructor() {
    }
}

按类创建空对象

let dto = new TransactionDto()   // ts object
let json = {name:"Kamal",age:40} // js object

let transaction: TransactionDto = Object.assign(dto,JSON.parse(JSON.stringify(json)));//conversion

你可以使用这个npm包。https://www.npmjs.com/package/class-converter

它很容易使用，例如:

class UserModel {
  @property('i')
  id: number;

  @property('n')
  name: string;
}

const userRaw = {
  i: 1234,
  n: 'name',
};

// use toClass to convert plain object to class
const userModel = toClass(userRaw, UserModel);
// you will get a class, just like below one
// const userModel = {
//   id: 1234,
//   name: 'name',
// }

如果你正在使用ES6，试试这个:

class Client{
  name: string

  displayName(){
    console.log(this.name)
  }
}

service.getClientFromAPI().then(clientData => {
  
  // Here the client data from API only have the "name" field
  // If we want to use the Client class methods on this data object we need to:
  let clientWithType = Object.assign(new Client(), clientData)

  clientWithType.displayName()
})

但遗憾的是，这个方法对嵌套对象不起作用。

我认为json2typescript是一个不错的选择 https://www.npmjs.com/package/json2typescript

你可以用一个带有注释的简单模型类将json转换为Class模型

用于工程

您可以像这样将json转换为属性

class Jobs {
  constructor(JSONdata) {
    this.HEAT = JSONdata.HEAT;    
    this.HEAT_EAF = JSONdata.HEAT_EAF;    
  }
  
}

 var job = new Jobs({HEAT:'123',HEAT_EAF:'456'});
