json-model-validator

轻量级请求数据检查&格式化工具

usage

安装

npm i json-model-validator

声明 json 模型

import {
    JSONModel,
    JSONMember,
    FIELD_TYPE,
} from 'json-model-validator';

@JSONModel
class SubSubModel {
    @JSONMember(FIELD_TYPE.ANY)
    subsub: any;
}

@JSONModel
class TestSubModel {
    @JSONMember(FIELD_TYPE.ANY)
    uuid: any;
    @JSONMember(SubSubModel)
    sub: SubSubModel;
}

@JSONModel
class TestModel {
    @JSONMember(FIELD_TYPE.NUMBER)
    uid: any;

    @JSONMember(FIELD_TYPE.STRING)
    code: string;

    @JSONMember(FIELD_TYPE.ARRAY(String), (cateIds) => cateIds.split(','))
    cateIds: string;

    @JSONMember(TestSubModel)
    t: TestSubModel;
}

校验请求或接口数据是否符合格式

import JSONValidator from 'json-model-validator',

console.log(JSONValidator(TestModel, { uid: '0', cateIds: '0,1', t: { uuid: 0 } }));
//  throw ValidationError, errorList ['待检查的数据 data.t.sub 应为 SubSubModel 对象，当前值为 undefined']

console.log(JSONValidator(TestModel, { uid: [0], cateIds: '0,1', t: { sub: { subsub: 0 } } }));
// {"t":{"sub":{"subsub":0},"uuid":""},"uid":0,"cateIds":["0","1"]}
