用angular 6中的json模式验证json

Question

This is the first time im working on json schema validation in Angular project.I need help to validate JSON(from REST API) with JSON schema. Below is sample json schema(generated online)

 {
  "$schema": "http://json-schema.org/draft-04/schema#",
  "type": "object",
  "properties": {
    "specifications": {
      "type": "array",
      "items": [
        {
          "type": "object",
          "properties": {
            "templateName": {
              "type": "string"
            }
          },
          "required": [
            "templateName"
          ]
        },
        {
          "type": "object",
          "properties": {
            "services": {
              "type": "array",
              "items": [
                {
                  "type": "object",
                  "properties": {
                    "servicename": {
                      "type": "string"
                    },
                    "servicedescription": {
                      "type": "string"
                    }
                  },
                  "required": [
                    "servicename",
                    "servicedescription"
                  ]
                }
              ]
            }
          },
          "required": [
            "services"
          ]
        },
        {
          "type": "object",
          "properties": {
            "javaplatform": {
              "type": "array",
              "items": [
                {
                  "type": "object",
                  "properties": {
                    "javaversion": {
                      "type": "string"
                    }
                  },
                  "required": [
                    "javaversion"
                  ]
                }
              ]
            }
          },
          "required": [
            "javaplatform"
          ]
        }
      ]
    }
  },
  "required": [
    "specifications"
  ]
}

Below is my sample json

{
"specifications": [
    {
        "templateName": "specifications"
    },
    {
        "services": [
            {
                "servicename": "name",
                "servicedescription": "description"
            }
        ]
    },
    {
        "javaplatform": [
            {
                "javaversion": "1.8"
            }
        ]
    }
  ]
}

Kindly let me know how to validate json in angular6/javascript/jquery?

Answer 1

you can try Ajv

here is example code

import * as Ajv from 'ajv'


var ajv = new Ajv();
var validate = ajv.compile(schema);
var valid = validate(data);
if (!valid) console.log(validate.errors);
