Question

我正在使用 kibana safesearch 获取 csv 格式的数据提取物，由于我对此很陌生，所以我来这里寻求帮助。我需要计算我们在我使用的 json 文件（或者我有一个字段名称“ref”，它有一个关联的值，但它是从 0 到 99，我需要它是 1 到 1000）。这是我使用的文件示例：

    {
  "header": {
    "salesOrderId": "toto",
    "salesOrderDate" : "2021-02-16T19:04:14+01:00",

  ]
}

Answer 1

所以我找到的答案是：

try { 
     return doc['offer.product.productCode'].size(); 
} catch(Exception e){ 
   return ''; 
}
