Question

我的脸部版机器人有2200个订阅者，所以我使用以下代码每天向他们发送图像。但是，对于从bot框架

捕获的错误的大多数用户来说，此代码失败了

 public static class MessagesSender
{
    public static void SendSpecificMessage(string botName, string serviceURL, string botId, string messageCode, string messageText, string imageURL, Customer customer , Guid logId)
    { 
        var connector = new ConnectorClient(new Uri(serviceURL)); 

        Thread thread = new Thread(() => SendMessage(botName, serviceURL, botId, messageCode, messageText, imageURL, customer, connector , logId));
        thread.Start(); 

    }

    private static void SendMessage(string botName, string serviceURL, string botId, string messageCode, string messageText, string imageURL, Customer customer, ConnectorClient connector , Guid logId)
    {


        try
        {


        Task.Run(async () =>
        {
            IMessageActivity message = Activity.CreateMessageActivity();
            //defining accounts 
            var userAccount = new ChannelAccount(name: customer.name, id: customer.fromidstate);
            var botAccount = new ChannelAccount(name: botName, id: botId);

            //creating conversation
            var conversationId =  await connector.Conversations.CreateDirectConversationAsync(botAccount, userAccount);


            message.From = botAccount;
            message.Recipient = userAccount;



            message.Text = "Daily Image";
            message.Conversation = new ConversationAccount(id: conversationId.Id.Replace("@", string.Empty));



            if (!string.IsNullOrEmpty(imageURL))
            {
                message.Attachments = new List<Attachment>();
                message.Attachments.Add(new Attachment()
                {
                    ContentUrl = imageURL,
                    ContentType = "image"
                });
            }




            await connector.Conversations.SendToConversationAsync((Activity)message);



        }).Wait();
        }
        catch ( Exception ex)
        {
            throw ex;

        } 
    }
}

我不知道该怎么做，因为当我发送一条消息时，它工作正常，但并非所有2200条消息都没有发送，如果我发送给10个人，那很好。而且主要的问题是文本被传递但不是图像

Answer 1

Facebook API返回错误。看起来你正在达到限制。解决方案是降低发送图像的速度。

如果要确认，可以查看错误返回代码（＆＃34; 613＆＃34;）
