  "title": "InvoiceOutputModel",
  "type": "object",
  "properties": {
    "DueDate": { "type": "string" },
    "Balance": { "type": "number" },

      }
    },
    "TotalAmt": { "type": "number" }
  }
}

输出映射模板（销售发票示例）

以下是与已转换的 JSON 数据格式对应的输出映射模板。此处的模板变量基于原始 (而非已转换的) JSON 数据格式：

#set($inputRoot = $input.path('$'))
{
  "DueDate": "$inputRoot.DueDate",
  "Balance": $inputRoot.Balance,
  "DocNumber": "$inputRoot.DocNumber",
  "Status": "$inputRoot.Status",
  "Line": [
#foreach($elem in $inputRoot.Line)
    {
      "Description": "$elem.Description",
      "Amount": $elem.Amount,
      "DetailType": "$elem.DetailType",
      "Customer": "$elem.ExpenseDetail.Customer.value ($elem.ExpenseDetail.Customer.name)",
      "Ref": "$elem.ExpenseDetail.Ref.value ($elem.ExpenseDetail.Ref.name)",
      "Account": "$elem.ExpenseDetail.Account.value ($elem.ExpenseDetail.Account.name)",
      "LineStatus": "$elem.ExpenseDetail.LineStatus"
    }#if($foreach.hasNext),#end
        
#end
  ],
  "TotalAmt": $inputRoot.TotalAmt
}
