我正在使用 VSCodeExtention IBM Blockchain Platform 在打字稿中运行示例智能合约。

我只是按照这个步骤进行扩展：

  1. 创建新项目（在打字稿中）
  2. 打包这个项目
  3. 安装智能合约
  4. 实例化智能合约

当我更新我的模型 MyCloth 并运行时，npm run build一切都很顺利。但是当我尝试升级我的 SmartContrat 时，我收到了这个错误：

我的模型：

import { Object, Property } from 'fabric-contract-api';
import { Stakeholder, State } from '../enum';

@Object()
export class MyClothe {

    @Property()
    public id: string;

    @Property()
    public issuer: Stakeholder = Stakeholder.XXX; // the name or id of the company who issue the asset

    @Property()
    public owner: Stakeholder = Stakeholder.XXX; // the current owner of the asset

    @Property()
    public maturityDate: number = Date.now() + 1000 * 60 * 60 * 24 * 365; // the end date return of the asset in milisecond

    @Property()
    public additionalFee: number = 0; // Fee to charge the customer

    @Property()
    public currentState: State = State.Issued; // current state of the asset


    @Property()
    public params: any = { //new attribute added
        param1: 'param1',
        param2: 'param2',
    }; // Additional params in the future need
}

The problem is due to this section of your model

    @Property()
    public params: any = { //new attribute added
        param1: 'param1',
        param2: 'param2',
    }; //

The fabric-contract-api looks like it can't handle the type of any. Also it would appear it cannot handle the type object either which would probably be more appropriate for your example). Whether it should be able to handle those types I'm not sure but what would be good is for it to provide a better error message. In your case the solution would be to define another type to explicitly describe the params property.

import {Params} from './paramdef'
...
...
    @Property()
    public params: Params = { //new attribute added
        param1: 'param1',
        param2: 'param2',
    }; //

paramdef.ts

import {Object, Property} from 'fabric-contract-api';

@Object()
export class Params {
   @Property()
   param1: string;
   @Property()
   param2: string;
}
