Azure LogicApps：從字符串到浮點數的轉換返回零
[英]Azure LogicApps: Conversion from String to Float returns zero
問題描述
我很驚訝地看到這一點，但我見證了在某些情況下，字符串值沒有按預期轉換為浮點數； 大多返回零。
下圖顯示了發生的情況。 正如你看到的我有2個變量，即var_MarginStr類型的string和var_MarginValues類型的float在我的邏輯應用。 我分配var_MarginVal如下：
var_MarginVal = float(string(variables('var_MarginStr')))
在我的工作中，在將新 blob 插入 blob 存儲帳戶后觸發我的邏輯應用程序。 blob 的內容 (*.csv) 被傳遞到一個 Azure 函數，該函數返回一個JSON對象。 然后將 JSON 對象循環到每個項目上，並通過存儲過程發送到我的數據庫。
我已經檢查了我的 Azure 函數，它可以完美地將內容轉換為 JSON，並且來自這樣的響應是：
{
"fileName": "20200307-PLC-JKB-Margin.csv",
"agentName": "PLC",
"noOfRecords": 5,
"data": [
{
"accountId": "JKB1234LC",
"marginValue": "0.00"
},
{
"accountId": "JKB4321LC",
"marginValue": "1200000.00"
},
{
"accountId": "JKB5678LC",
"marginValue": "6000000.00"
},
{
"accountId": "JKB8765LC",
"marginValue": "4000000.00"
},
{
"accountId": "JKB9123LC",
"marginValue": "0.00"
}
]
}
這是我的整個 LogicApp：

默認情況下，當 For Each 運行時，它會同時運行迭代。 不保證變量使用當前迭代的值。 如果您將 For Each 更改為按順序運行，它將與變量一起使用。 在 For Each 設置中，打開並發控制並將並行度設置為 1。如果您希望循環並行運行，另一個選項是刪除循環中變量的使用。
此頁面上的循環 Microsoft 文檔https://docs.microsoft.com/en-us/azure/logic-apps/logic-apps-control-flow-loops說
要在每次循環迭代期間從對變量的操作中獲得可預測的結果，請按順序運行這些循環。 例如，當並發運行的循環結束時，遞增、遞減和追加到變量操作會返回可預測的結果。 但是，在並發運行循環中的每次迭代期間，這些操作可能會返回不可預測的結果。
