   644 words   4 minutes 

最近收到一份JSON格式資料
要實作一個API程式
在沒有任何文件囧境
看完好幾千行JSON
後來用Firefox下比對JSON長度
但測試實候發現有些 integer 型態我傳成 string
我發現單純用Firefox肉眼看不行
在想有什麼實用工具可以驗證

檢查JSON type

Paste JSON as Code -vscode套件

Paste JSON as Code - Visual Studio Marketplace
Paste JSON as Code 可以產生JSON Schema
還可以產生測試程式
有測試nodejs，還是無法知道哪裡有問題

aa = require('./json_check');

aa.testToJson(`{
    "test": "test"
}`);

他還能產生JSON schema
可以把JSON Schema貼到這個上面
下面會回傳錯誤訊息
JSON Schema Validator - Newtonsoft

線上驗證工具

JSON Schema Validator - vscode套件本機好像失效，評價3顆星….
Json Schema with VS Code – Omkar’s Tech Blog

範例
GitHub - omkarmore83/json-schema-vscode-example: Examples for Json Schema with Visual Studio code

內建VSCODE就有檢查工具

內建就有的功能，但必須設定schema

{
    "json.schemas": [
        {
            "fileMatch": [
                "/lyric.api.json"
            ],
            "url": "./lyric.schema.json"
        }
    ]
}

比較注意的地方fileMatch不需要加.
加.反而找不到位置
可搭配*用在fileMatch

其他工具

GitHub - java-json-tools/json-schema-validator: A JSON Schema validation implementation in pure Java, which aims for correctness and performance, in that order

一些JSON SCHEMA範例
JSON Schema Store

做完這個，我發現XML要怎麼快速檢單驗證呢
但發現XML有一個叫XSD

一些工具如下，參考來源:XML Schema(XSD)验证工具？ - 码客
Xerces
xmlstarlet
XML validator and editor for Windows
Download XML Notepad 2007 from Official Microsoft Download Center
筆記：Java IDE 從 XSD 轉出 XML – Aya Wong – Medium
W3C XML Schema (XSD) Validation online
Jax 的工作紀錄: [PHP][Java][C#] 用 XSD 驗證 XML

最後找了範例用在W3C XML Schema (XSD) Validation online
可以驗證成功
