Javascript JSON数据验证失败

我没有通过JSON数据验证测试，在测试中，我应该创建一个JSON对象persons，其中包含属性名称、员工ID、经验、公司和名称，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了解NodeJ 这是json文件（data.json）

以下是js文件：

let jsonData = require('./data.json');
let persons=JSON.parse('./data.json', jsonData);
for(i in persons){
    console.log(persons.i);
}

下面是验证文件：

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")
}

});

我得到的JSON数据无效。状态：失败

从您需要创建的内容的描述来看，您似乎需要这些对象的数组

因此，JSON应该是

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

那么“JS”就是

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

用空格丢失周围的

“

员工ID？绝对不是brother@taygetos，我在这里输入的这个错误。如果，正如你所说，你的JSON存在并从它自己的文件中加载，那么包装

”

绝对是个问题。但是，这可能不是您唯一的问题。从您的示例中，您的EmployeeId和经验是字符串，但您正在验证数字。以下是错误@Bravo```[{message:'“value”不包含1个必需的值，路径：[]，键入：'array.includeRequiredUnknowns'，上下文：[Object]}]，\u Object:[]，注释：[Function]}'JSON数据无效。状态：失败“```顺便说一句，我想通过公平的方式通过这个实践，只有这样，如果你有什么建议，除了verify.js，然后提前感谢这里没有错误-这通过@Krishnakant。。。“``不是一个错误，这一次你的JSON是正确的，但有一件事我还是不明白，当我在你写的时候尝试你的JSON时，它不起作用，但当我尝试它作为“{”个人“：{”姓名“：”某某姓名“，”雇员ID“：123”，“经验“：123”，“公司“：”某某公司“，”指定“：”某某指定“}”成功了，这两个数据有什么区别？在.json文件中需要\吗？

let persons=require('./data.json');
for(let i in persons){
    console.log(persons[i]);
}

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")
    }

});

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