pumData:{ 2021-01:{ '一':{ num:1,allNum:20,rate:0.5 } , '二':{ num:2,allNum:40,rate:0.33 } , } , 2021-02:{ '三':{ num:1,allNum:20,rate:0.5 } , '四':{ num:2,allNum:40,rate:0.33 } , } , } 使用js输出 perNum:{ legends:[](pumData的key), xData:[](pumData中每一条数据的key 比如'2021-01'的key为'一'), serirData:[ { name:""(pumData的key) ,data:[](与name对应的xData的num组成的数组)} ] }

可以使用以下代码将 pumData 转换为 perNum 格式：

const perNum = {
  legends: Object.keys(pumData),
  xData: [],
  serirData: []
};

for (const year in pumData) {
  const yearData = pumData[year];
  const yearSerirData = {
    name: year,
    data: []
  };

  for (const month in yearData) {
    const monthData = yearData[month];
    perNum.xData.push(month);
    yearSerirData.data.push(monthData.num);
  }

  perNum.serirData.push(yearSerirData);
}

这里首先初始化了 perNum 对象，其中 legends 为 pumData 的 key 组成的数组，xData 为 pumData 中每一条数据的 key（即每个月份）组成的数组。然后遍历 pumData，将每个年份的数据转为对应的 serirData。在 serirData 中，name 为年份，data 为该年份下每个月份的 num 组成的数组。

{ "tenant": 1, "action": "AuditPass", "ordId": 1, "bizType": "sms", "partnerId": 123, "ordRemark": "备注信息", "curAuditor": "", "auditTemplateCode": "", "currentNum": 0, "allNum": 1, "auditDetail": "", "orderPostParamDTO": { "param": { "qualificationGroupId":"12345", "organizationCode":"2222", "qualificationGroupName":"22222" }, "auditRemark": "", "exceptionOrder": }, "orderCreateTime": 1230 } 将改消息解析成对象

这是一段 JSON 格式的数据，可以通过各种编程语言中的 JSON 解析器将其解析成对象。以下是 Python 中的示例代码：

import json

data = '{ "tenant": 1, "action": "AuditPass", "ordId": 1, "bizType": "sms", "partnerId": 123, "ordRemark": "备注信息", "curAuditor": "", "auditTemplateCode": "", "currentNum": 0, "allNum": 1, "auditDetail": "", "orderPostParamDTO": { "param": { "qualificationGroupId":"12345", "organizationCode":"2222", "qualificationGroupName":"22222" }, "auditRemark": "", "exceptionOrder": }, "orderCreateTime": 1230 }'

obj = json.loads(data)

print(obj)

运行以上代码可以将该 JSON 数据解析成 Python 对象，并将其打印出来。你也可以使用其他编程语言的 JSON 解析器来解析该数据。
