在Azure中检索Chat Bot对话数据 [英] Retrieving Chat Bot conversation data in Azure
问题描述
首先简要介绍一下背景:Bot框架将对话数据存储在Azure表/Cosmos DB(在我的情况下为Azure表)中的存储中.对于每个对话，都会在Azure表中创建一个条目，其中包含时间戳，用户ID，对话消息和其他详细信息.
A brief background first: The Bot framework stores the conversation data within a storage either Azure tables/Cosmos DB (Azure tables in my case). For each conversation there is an entry made into the Azure table with the timestamp, userid, conversation messages and other details.
我正尝试使用C#中的自定义代码从Azure表存储中检索对话详细信息，如下所示.
I am trying to retrieve the conversation details from Azure table storage using custom code in C# as shown below.
Microsoft.WindowsAzure.Storage.CloudStorageAccount storageAccount = Microsoft.WindowsAzure.Storage.CloudStorageAccount.Parse(connectionString);
Microsoft.WindowsAzure.Storage.Table.CloudTableClient tableClient = storageAccount.CreateCloudTableClient();
CloudTable table = tableClient.GetTableReference("botdata");
TableQuery<DynamicTableEntity> projectionQuery = new TableQuery<DynamicTableEntity>().Where(TableQuery.GenerateFilterCondition("PartitionKey", QueryComparisons.Equal, "directline:user"));
var dataRow = table.ExecuteQuery(projectionQuery).Where(q => q.RowKey == "souvik").FirstOrDefault();
var conversation = Encoding.UTF8.GetString(dataRow.Properties["Data"].BinaryValue);
Console.WriteLine(conversation);
当我检索Azure表存储中以二进制格式存储的数据时，我得到一些乱码，类似这样-\u001f�\b\0\0\0\0\0\u0004\0��\u0005\0C���\u0002\0\0\0.数据如下图所示，在Azure存储资源管理器中显示-
I am getting some gibberish text, something like this- \u001f�\b\0\0\0\0\0\u0004\0��\u0005\0C���\u0002\0\0\0 when I retrieve the data stored in Binary format in the Azure table storage. The data looks something like as shown below in the Azure storage explorer-
我已经为每个对话进行了尝试和测试，并且看到每次键入并将数据发送到bot并获得响应时，都会使用正确的时间戳将新记录添加到Azure表中.是检索数据的正确方法还是我做错了什么?让我知道是否可以添加更多详细信息.
I have tried and tested for each conversation and I have seen that each time I type and send a data to the bot and get a response, new records are getting added to the Azure table with correct timestamp. Is it the correct way of retrieving the data or am I doing something wrong? Let me know if I can add more details.
更新1:
我已引用此-如何检索保存的会话数据在Azure(Tablelogger)中，但没有对我的问题有太大帮助.
I have referred this- How to retrieve Saved Conversation Data in Azure (Tablelogger) but did not get much help my issue.
Update-2
基于以下Fei的回答，我只是注意到当我将PartitionKey用作directline:user或directline:conversation时，我将反序列化的值表示为{}，但是如果我使用directline:private，则会得到类似以下的信息-
Based on Fei's answer below, I just noticed when I use the PartitionKey as directline:user or directline:conversation I get the deserialized values as {} but if I use directline:private I get somthing like this-

我觉得上面JSON中的DialogState数据需要解密吗?
I have a feeling that the DialogState data in the JSON above needs to be decrypted?
对于我键入的每条消息和收到的响应，在Azure表中插入了三个记录，每个记录都有不同的PartitionKey，分别是-directline:private，directline:user和directline:conversation.
For every message I type and the response I receive, there are three records inserted into the Azure table each with a different PartitionKey which are- directline:private, directline:user and directline:conversation.
推荐答案
如果您想使用 WindowsAzure.Storage客户端库可以从表存储中检索实体，并从 Data属性 中提取数据，您可以参考以下代码.
If you’d like to use WindowsAzure.Storage client library to retireve entities from table storage and extract data from Data property, you can refer to the following code.
CloudStorageAccount storageAccount = CloudStorageAccount.Parse("DefaultEndpointsProtocol=https;AccountName={your_account_name};AccountKey={your_account_key};EndpointSuffix=core.windows.net");
CloudTableClient tableClient = storageAccount.CreateCloudTableClient();
CloudTable table = tableClient.GetTableReference("botdata");
TableQuery<MessageEntity> query = new TableQuery<MessageEntity>().Where(TableQuery.GenerateFilterCondition("PartitionKey", QueryComparisons.Equal, "emulator:user"));
foreach (MessageEntity entity in table.ExecuteQuery(query))
{
string mydata = "";
using (var msi = new MemoryStream(entity.Data))
using (var mso = new MemoryStream())
{
using (var gs = new GZipStream(msi, CompressionMode.Decompress))
{
gs.CopyTo(mso);
}
mydata = Encoding.UTF8.GetString(mso.ToArray());
}
object data = JsonConvert.DeserializeObject(mydata);
//.....
}
MessageEntity:
public class MessageEntity : TableEntity
{
public MessageEntity(string pk, string rk)
{
this.PartitionKey = pk;
this.RowKey = rk;
}
public MessageEntity() { }
public string BotId { get; set; }
public string ChannelId { get; set; }
public string ConversationId { get; set; }
public byte[] Data { get; set; }
public string UserId { get; set; }
}
测试结果:
注意:
- In source
code,
you can find the Data property is defined as
byte[]in BotDataEntity class. - In JasonSowers's reply, he has shared the information about serialize and deserialize of Data property.
