Azure 逻辑应用程序根据条件从两个数组集合中形成一个新数组

Question

我有两个数组集合如下

"**entitiy1**": [
{
  "lotNumber": "Lot04",
  "itemId": "1000123",
  "locationId": "65668"
},
{
  "lotNumber": "Lot02",
  "itemId": "1000123"
  "locationId": "1000006"
}]


"**entitiy2**":[
{
"storageLocationId": "1000006",
"storageLocationName": "Back Cooler"
},
{
"storageLocationId": "1000007",
"storageLocationName": "Stock Room"
}]

最终的新数组应该是通过使用locationId和storageLocationId匹配数据形成的

[{
  "lotNumber": "Lot02",
  "itemId": "1000123"
  "locationId": "1000006",
  "storageLocationName":"Back Cooler"
}]

我正在尝试如下。我正在遍历一个数组并使用当前项目匹配条件过滤第二个数组。 但是每次循环总是显示失败。它显示为上一个和下一个迭代链接。当我们滚动到下一次迭代时，它显示匹配项已通过。但我只需要匹配的输出

第3行有匹配的记录

如何将所有匹配记录组成最终数组？

"For_each": {
            "actions": {
                "Append_to_array_variable": {
                    "inputs": {
                        "name": "finalArray",
                        "value": "@outputs('Compose')"
                    },
                    "runAfter": {
                        "Compose": [
                            "Succeeded"
                        ]
                    },
                    "type": "AppendToArrayVariable"
                },
                "Compose": {
                    "inputs": {
                        "itemCount": "@items('For_each')?['itemCount']",
                        "locationId": "@items('For_each')?['locationId']",
                        "locationName": "@body('Filter_array')?[0]['storageLocationName']",
                        "lotNumber": "@items('For_each')?['lotNumber']",
                        "sellByDate": "@items('For_each')?['sellByDate']"
                    },
                    "runAfter": {
                        "Filter_array": [
                            "Succeeded"
                        ]
                    },
                    "type": "Compose"
                },
                "Filter_array": {
                    "inputs": {
                        "from": "@body('Select_ESO_Locations')",
                        "where": "@equals(string(item()['storageLocationId']), string(items('For_each')['locationId']))"
                    },
                    "runAfter": {},
                    "type": "Query"
                }
            },
            "foreach": "@body('Select_LSO_Locations')",
            "runAfter": {
                "Initialize_variable": [
                    "Succeeded"
                ]
            },
            "type": "Foreach"
        }

Answer 1

您的撰写操作失败，因为您正尝试使用硬编码索引 [0] 从过滤后的数组中读取数据。只需将您读取值的方式更改为在 Compose 中的每个内部代替

"locationName": "@body('Filter_array')?[0]['storageLocationName']",

做

"locationName": "@body('Filter_array')?[0]?['storageLocationName']",

您修改后的 For Each 应如下所示

"For_each": {
            "actions": {
                "Append_to_array_variable": {
                    "inputs": {
                        "name": "finalArray",
                        "value": "@outputs('Compose')"
                    },
                    "runAfter": {
                        "Compose": [
                            "Succeeded"
                        ]
                    },
                    "type": "AppendToArrayVariable"
                },
                "Compose": {
                    "inputs": {
                        "itemCount": "@items('For_each')?['itemCount']",
                        "locationId": "@items('For_each')?['locationId']",
                        "locationName": "@body('Filter_array')?[0]?['storageLocationName']",
                        "lotNumber": "@items('For_each')?['lotNumber']",
                        "sellByDate": "@items('For_each')?['sellByDate']"
                    },
                    "runAfter": {
                        "Filter_array": [
                            "Succeeded"
                        ]
                    },
                    "type": "Compose"
                },
                "Filter_array": {
                    "inputs": {
                        "from": "@body('Select_ESO_Locations')",
                        "where": "@equals(string(item()['storageLocationId']), string(items('For_each')['locationId']))"
                    },
                    "runAfter": {},
                    "type": "Query"
                }
            },
            "foreach": "@body('Select_LSO_Locations')",
            "runAfter": {
                "Initialize_variable": [
                    "Succeeded"
                ]
            },
            "type": "Foreach"
        }

PS 话虽这么说，也请考虑以下选项 1) 使用液体变换将 json 变换为 json。通过编写液体变换，您可以更好地控制变换。请注意，这需要一个集成帐户，如果您在企业中使用它，我强烈建议您使用此路径 2) 使用 Azure 函数进行转换
