Question

REST api在发送消息时详细说明了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"                        // ?
}

我已经标记了我不确定的领域。目前，我发送请求并获得500服务器错误作为回报。该机器人使用本地僵尸模拟器在本地工作正常。

此JSON需要在Android应用中构建。

编辑：以下是截获的JSON和我发送的回复

在JSON中，text是用户发送给bot的消息。当我使用直接线路API启用网络聊天时出现500错误。但它会在5或6个小时后自动解决。

顺便提一下，根据微软的帮助，他们给了我这两个选项， Direct Line将在两种情况下返回错误：

您的消息存在问题或直接线路内部错误
您的机器人正在返回错误消息

正如您所提到的，在模拟器中它可以正常工作。所以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)
}

这里与我分享C＃代码，可能会对你有帮助，

 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;
        }

我创建了一个具有相同JSON的类，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; }
    }

对于对话，

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

我希望这个答案可以帮助您解决问题。干杯！
