使用Microsoft BotConnector发送新消息的POST正文

Question

REST在发送消息时详细介绍了POST主体的JSON格式，但是不清楚字段中的内容。这是格式..。

{
  "id": "string",                         // ?
  "conversationId": "string",             // Conversation ID
  "created": "2016-06-22T10:45:48.618Z",  // Current time?
  "from": "string",                       // Username?
  "text": "string",                       // The message to be sent
  "channelData": "string",                // ?
  "images": [
    "string"                              // Image URL?
  ],
  "attachments": [
    {
      "url": "string",                    // Attachment URL
      "contentType": "string"             // ContentType
    }
  ],
  "eTag": "string"                        // ?
}

我已经把我不确定的地方标记出来了。现在，我发送请求并得到一个500服务器错误作为回报。该机器人使用本地bot仿真器在本地很好地工作。

这个JSON需要在Android应用程序中构建。

编辑：这里是我要发送的截取的JSON和响应

Answer 1

在JSON中，文本是用户发送给bot的消息。我得到了500个错误，当我启用网络聊天直接行API。但它在5或6个小时后就自动解决了。

顺便说一下，根据微软的帮助，他们给了我这两个选项，Direct会在两种情况下返回错误：

1. 您的消息有问题，或者在直通车中有内部错误。
2. 您的bot正在返回一条错误消息。

正如您所提到的，在模拟器中，它工作得很好。这是因为你传递的信息。

Message {
id (string, optional): ID for this message ,
conversationId (string, optional): Conversation ID for this message ,
created (string, optional): UTC timestamp when this message was created ,
from (string, optional): Identity of the sender of this message ,
text (string, optional): Text in this message ,
channelData (string, optional): Opaque block of data passed to/from bot via the ChannelData field ,
images (Array[string], optional): Array of URLs for images included in this message ,
attachments (Array[Attachment], optional): Array of non-image attachments included in this message ,
eTag (string, optional)
}
Attachment {
url (string, optional): URL for this attachment ,
contentType (string, optional): Content type for this attachment 
} 

Conversation {
conversationId (string, optional): ID for this conversation ,
token (string, optional): Token scoped to this conversation ,
eTag (string, optional)
} 

在这里我分享C#代码，也许这会对你有帮助，

 private async Task<bool> PostMessage(string message)
        {

            client = new HttpClient();
            client.BaseAddress = new Uri("https://directline.botframework.com/api/conversations/");
            client.DefaultRequestHeaders.Accept.Clear();
            client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
            client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("BotConnector", "[YOUR BOT TOKEN]");
            response = await client.GetAsync("/api/tokens/");
            if (response.IsSuccessStatusCode)
            {
                var conversation = new Conversation();
                response = await client.PostAsJsonAsync("/api/conversations/", conversation);
                if (response.IsSuccessStatusCode)
                {
                    Conversation ConversationInfo = response.Content.ReadAsAsync(typeof(Conversation)).Result as Conversation;
                    string conversationUrl = ConversationInfo.conversationId+"/messages/";
                    BotDirectLineApproch.Models.Message msg = new BotDirectLineApproch.Models.Message() { text = message };
                    response = await client.PostAsJsonAsync(conversationUrl,msg);
                    if (response.IsSuccessStatusCode)
                    {
                        response = await client.GetAsync(conversationUrl);
                        if (response.IsSuccessStatusCode)
                        {
                            MessageSet BotMessage = response.Content.ReadAsAsync(typeof(MessageSet)).Result as MessageSet;
                            ViewBag.Messages = BotMessage;
                            IsReplyReceived = true;
                        }
                    }
                }

            }
            return IsReplyReceived;
        }

我用相同的JSON创建了一个类，如下所示，

public class MessageSet
    {
        public Message[] messages { get; set; }
        public string watermark { get; set; }
        public string eTag { get; set; }
    }

    public class Message
    {
        public string id { get; set; }
        public string conversationId { get; set; }
        public DateTime created { get; set; }
        public string from { get; set; }
        public string text { get; set; }
        public string channelData { get; set; }
        public string[] images { get; set; }
        public Attachment[] attachments { get; set; }
        public string eTag { get; set; }
    }

    public class Attachment
    {
        public string url { get; set; }
        public string contentType { get; set; }
    }

在谈话中，

public class Conversation
    {
        public string conversationId { get; set; }
        public string token { get; set; }
        public string eTag { get; set; }
    }

我希望这个答案能帮助你解决你的问题。干杯!
