通過輸入數據存儲綁定按隊列觸發Azure功能

Question

我正在嘗試為隊列觸發功能提供輸入數據存儲綁定。

VTRequest是被推送到隊列的對象，而VTEntity是被保存在數據庫中的對象。

如果function.json

{
  "bindings": [
    {
      "name": "vtAPIRequest",
      "type": "queueTrigger",
      "direction": "in",
      "queueName": "vtqueue",
      "connection": "vt_STORAGE"
    },
    {
      "type": "table",
      "name": "outVTAPIDataTable",
      "tableName": "data",
      "connection": "vt_STORAGE",
      "direction": "out"
    },
    {
      "type": "table",
      "name": "vtDataRow",
      "tableName": "VTData",
      "partitionKey": "VT",
      "rowKey": "{queueTrigger}.{hash}",
      "take": 1,
      "connection": "vt_STORAGE",
      "direction": "in"
    }
  ],
  "disabled": false
}

using System;


public class VTEntity {

    public string PartitionKey { get; set; }
    public String RowKey { get; set; }
    public string hash { get; set; }
    public string userID { get; set; }    
}



public class VTRequest {

    public string hash { get; set; }
    public string userID { get; set; }    
}


public static void Run(VTRequest vtAPIRequest, VTEntity vtDataRow, 
        TraceWriter log, IAsyncCollector<VTEntity> outVTAPIDataTable) {


    if(null != vtDataRow) {
       .....
    }

}

這是我得到的錯誤日志：

2017-10-09T12:06:07.840 Exception while executing function: Functions.VTAPIQueue. Microsoft.Azure.WebJobs.Host: Exception binding parameter 'vtDataRow'. Microsoft.Azure.WebJobs.Host: '{

}.asdasdasd' is not a valid value for a partition key or row key.

我確實在相關的數據庫中有此記錄：

我想查詢隊列對象vtAPIRequest.hash傳遞的哈希的數據庫

有辦法嗎？

您rowKey了，只需將rowKey的綁定rowKey為

"rowKey": "{hash}",
