DataEase@123456

地址：
http://10.10.14.203/de2api/login/localLogin

content-type: application/json
数据：
{
    "name": "XkdqNzblA7zA9bmvcDs1lR4Dg2/bVaPnYN0+7y/VfyR2XoJ/Miu9gqKa5kVQe/reZyyAgUKqgD1AJwEKsvXC9fyeccIcAWqUwg6gKNoY7Wu4iZM6cJ6ri3CLhqtOGlHRLrn105btKxSrt/nM71pEy8a8lYbCBZRGqHnBDU1/JAs=",
    "pwd": "a/w4bFGfyY2BqZ6xEM5cj6ChOxC7ves8sJM0wUAKnBtqdIYHwxMLBDWKgmua0EMH7EvRy5S6yirz3VZI+fpGQAZF8jX+7evIZxdQq2jJU7r5EJPY5L+AA/a3zbuOvoOEtOdh5Y9nNdI1jSEzqH4m9IP/ADRFhF1xEfmemQKmU08="
}

返回：
{
    "code": 0,
    "msg": null,
    "data": {
        "token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ1aWQiOjEsIm9pZCI6MSwiZXhwIjoxNzM0MDQ4MDEyfQ.9-scx4pBDlsvjL28aI7VaWPcnO4lNkc7-KO8SuzWPzo",
        "exp": 1734048012144
    }
}


第二步：拷贝母屏生成可编辑临时副本
地址：
http://10.10.14.203/de2api/dataVisualization/copy

Header:
x-de-token:
eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ1aWQiOjEsIm9pZCI6MSwiZXhwIjoxNzM0MDQ2ODc3fQ.42oSabyyDAx-TPJbJoPgwsMFtsjRmZMM90Taqr1l7nQ

参数以json格式传递，不要用form-data或者x-www-form-urlencoded等其它格式：
{
    "nodeType": "leaf",
    "name": "云南省教育决策支持系统【市州】-copy",
    "type": "dataV",
    "id": "1036286881547030528",
    "pid": "1036643788262608896"
}
响应：
{"code":0,"msg":null,"data":"1064853824788893696"}

第三步：将临时副本保存下来
地址：
http://10.10.14.203/de2api/dataVisualization/saveCanvas

数据：

{
    "canvasStyleData": TODO ,
    "componentData": TODO ,
    "appData": null,
    "id": "1064853824788893696",
    "name": "云南省教育决策支持系统【市州】-copy",
    "pid": "1036643788262608896",
    "status": 1,
    "selfWatermarkStatus": true,
    "type": "dataV",
    "creatorName": null,
    "updateName": null,
    "createTime": 1734047402783,
    "updateTime": 1734047402783,
    "watermarkInfo": null,
    "weight": null,
    "mobileLayout": false,
    "dataState": "ready",
    "optType": "copy"
}

其中 canvasStyleData 和 componentData 可以通过读取数据库母屏数据的办法获取到
