JSON 数据验证失败

Question

我没有通过 JSON 数据验证测试，我应该在其中创建一个具有名称、员工 ID、经验、公司和名称属性的 JSON 对象人员，并使用循环访问它。我只是在学习 JSON，我认为问题在于它也需要 nodejs 的知识，这里是 json 文件 (data.json)'{"Name":"someName","EmployeeID":123,"Experience":123,"Company":"somecompany","Designation":"someDesignation"}'这是js文件：let jsonData = require('./data.json');let persons=JSON.parse('./data.json', jsonData);for(i in persons){    console.log(persons.i);}这是验证文件：const Joi = require('joi');const fss =require('fs');const schema = Joi.object().keys({    Name: Joi.string().required(),    EmployeeID: Joi.number().required(),    Experience: Joi.number().required(),    Company: Joi.string().required(),    Designation: Joi.string().required()});const personSchema=Joi.object().keys({  persons:schema.required()}).required();var data;try{ data = require("./data.json");    }catch(e){ data={};}var XMLWriter = require('xml-writer');    xw = new XMLWriter;// You can also pass a callback which will be called synchronously with the validation result.Joi.validate(data, personSchema, function (err, value) {if(err==null){     console.log("JSON data is valid, Status: Passed");}else{    console.log("JSON data is invalid. Status: failed")}});我收到JSON 数据无效。状态：失败

Answer 1

根据您需要创建的内容的描述，您似乎需要这些对象的 Array

所以，JSON 应该是

[{"Name":"someName","EmployeeID":123,"Experience":123,"Company":"somecompany","Designation":"someDesignation"}]

那么“JS”将是

let persons=require('./data.json');

for(let i in persons){

    console.log(persons[i]);

}

验证器将是

const Joi = require('joi');

const fss = require('fs');

const schema = Joi.object().keys({

        Name: Joi.string().required(),

        EmployeeID: Joi.number().required(),

        Experience: Joi.number().required(),

        Company: Joi.string().required(),

        Designation: Joi.string().required()

    });

const personSchema = Joi.array().items(schema.required()).required();

var data;

try {

    data = require("./data.json");

} catch (e) {

    data = [];

}

var XMLWriter = require('xml-writer');

xw = new XMLWriter;

// You can also pass a callback which will be called synchronously with the validation result.

Joi.validate(data, personSchema, function (err, value) {

    if (err == null) {

        console.log("JSON data is valid, Status: Passed");

    } else {

        console.log(err, "JSON data is invalid. Status: failed")

    }

});

如果验证器文件应该保持不变，那么 JSON 需要如下

{"persons":{"Name":"someName","EmployeeID":123,"Experience":123,"Company":"somecompany","Designation":"someDesignation"}}
