[C# SDK] Storing a user's last access

  • Updated

Imagine that your challenge is to store the last time your user used a certain chatbot service.

 

For this, we will need:

  1. Create the BLiP C# SDK template project (see how in the BLiP documentation)
  2. Add the IBucketExtension interface to your MessageReceiver's constructor. Note: It will be injected automatically by the SDK.
  3. Use the SetAsync(string resourceId, Document d) method to store a document containing the last access date.
  4. Note: Use the GetAsync(string resourceId) method to retrieve previously saved information.

 

The code below shows how to save a json document containing the last accessed date.

public class BucketMessageReceiver : IMessageReceiver

{

    private readonly IBucketExtension _bucketExtension;

    private readonly IMessagingHubSender _sender;

    public BucketMessageReceiver(IMessagingHubSender sender, IBucketExtension bucketExtension)

    {

        _bucketExtension = bucketExtension;

        _sender = sender;

    }

    public async Task ReceiveAsync(Message message, CancellationToken cancellationToken)

    {

        //Store last access date

        var jsonLastAccess = new JsonDocument();

        jsonLastAccess.Add("lastAccessDate", DateTimeOffset.Now);

        await _bucketExtension.SetAsync(message.From.ToString(), jsonLastAccess);

        //Get last access date

        await _bucketExtension.GetAsync<JsonDocument>(message.From.ToString());

    }

}
