Question

当我尝试扫描dynamoDb表并使用AWS页面中的以下示例代码返回特定列时：

PS C:\Users\Hugo\Desktop\The store\web2\store\functions> npm install braintree
functions@ C:\Users\Hugo\Desktop\The store\web2\store\functions

我遇到以下异常：

消息：Amazon.DynamoDBv2.AmazonDynamoDBException：选择获取ALL_ATTRIBUTES时无法指定AttributesToGet ---- Amazon.Runtime.Internal.HttpErrorResponseException：抛出了类型'Amazon.Runtime.Internal.HttpErrorResponseException'的异常。

我该如何解决？

Answer 1

我不得不补充道：

  string tableName = "Thread";
  Table ThreadTable = Table.LoadTable(client, tableName);

  ScanFilter scanFilter = new ScanFilter();
  scanFilter.AddCondition("ForumId", ScanOperator.Equal, forumId);
  scanFilter.AddCondition("Tags", ScanOperator.Contains, "sortkey");

  ScanOperationConfig config = new ScanOperationConfig()
  {
    AttributesToGet = new List<string> { "Subject", "Message" } ,
    Filter = scanFilter
  };

  Search search = ThreadTable.Scan(config);

到ScanOperationConfig

像这样：

Select = SelectValues.SpecificAttributes

如何解决此异常：“选择获取ALL_ATTRIBUTES时无法指定AttributesToGet”？
