用于字符串操作的 Nifi jolt 变换

Question

我有一个 json 文档，我需要对其应用 jolt 转换，感谢任何帮助。 这是我的 json 文档。

{
    "name": "Wine Seller 1",
    "in_stock": "3800",
    "sold": "47",
    "products": [
    {
        "product_id":"001",
        "product_name":"Wine - Maipo Valle Cabernet",
        "description":"Aliquam augue q\uam, sollicitudin \nvitae, \"consectetuer\" \$100eget, rutrum at"
    },
    {
        "product_id":"002",
        "product_name":"Bacardi",
        "description":"Praesent blandit \lacinia erat. \n Vestibulum \"sed\" magna"
    },
.,
.'
.,
.
}

我希望输出删除所有， , , 根据描述，我想把所有的 \" 都放在那里。如下所示

{
    "name": "Wine Seller 1",
    "in_stock": "3800",
    "sold": "47",
    "products": [
        {
            "product_id": "001",
            "product_name": "Wine - Maipo Valle Cabernet",
            "description": "Aliquam augue quam, sollicitudin vitae, \"consectetuer\" $100eget, rutrum at"
        },
        {
            "product_id": "002",
            "product_name": "Bacardi",
            "description": "Praesent blandit lacinia erat. Vestibulum \"sed\" magna"
        },
.,
.,
.,
    ]
}

您可以在modify转换规范中连续使用split和join函数，假设您要在修复后基于JSON数据删除

\n

和

\t

组合，例如

[
  { // split the by "description" values by \n
    "operation": "modify-overwrite-beta",
    "spec": {
      "products": {
        "*": {
          "description": "=split('\n',@(1,&))"
        }
      }
    }
  },
  { // get rid of "\n"s
    "operation": "modify-overwrite-beta",
    "spec": {
      "products": {
        "*": {
          "description": "=join('',@(1,&))"
        }
      }
    }
  },
  { // split the by "description" values by \t
    "operation": "modify-overwrite-beta",
    "spec": {
      "products": {
        "*": {
          "description": "=split('\t',@(1,&))"
        }
      }
    }
  },
  { // get rid of "\t"s
    "operation": "modify-overwrite-beta",
    "spec": {
      "products": {
        "*": {
          "description": "=join('',@(1,&))"
        }
      }
    }
  }
]
