无法反序列化响应

Question

我已经搜索并找到了这个帖子：
Microsoft.Bot ConnectorClient SendMessage Unable to deserialize the response
但是没有代码和解释。

到目前为止，我有这个：

  var obj = model[i];
                    var userAccount = new ChannelAccount(obj.toId, obj.toName);
                    var botAccount = new ChannelAccount(obj.fromId, obj.fromName);
                    var connector = new ConnectorClient(new Uri(obj.serviceUrl));

                    IMessageActivity message = Activity.CreateMessageActivity();
                    if (!string.IsNullOrEmpty(obj.conversationId) && !string.IsNullOrEmpty(obj.channelId))
                    {
                        message.ChannelId = obj.channelId;
                    }
                    else
                    {
                        obj.conversationId = (await connector.Conversations.CreateDirectConversationAsync(botAccount, userAccount)).Id;
                    }

                    if (botAccount.Name == "")
                        botAccount.Name = "Bot";
                    if (userAccount.Name == "")
                        userAccount.Name = "User";



                    message.From = botAccount;
                    message.Recipient = userAccount;
                    message.Conversation = new ConversationAccount(id: obj.conversationId);
                    message.Text = "Hello, this is a notification";
                    message.Locale = "en-Us";
                    await connector.Conversations.SendToConversationAsync((Activity)message);

我的消息对象：

{Microsoft.Bot.Connector.ChannelAccount} 编号：“49gjgijl7a4inc821c” 名称：“机器人”

message.Recipient {Microsoft.Bot.Connector.ChannelAccount} ID：“默认用户” 名称：“用户”

message.Conversation {Microsoft.Bot.Connector.ConversationAccount} 编号：“a0m69i29gih3kjf3mc” 是组：空 名称：空

message.Text = "你好，这是一条通知"; message.Locale = "en-Us";

我在尝试发帖时遇到此错误：

无法反序列化响应。

e.InnerException

{"解析值时遇到意外字符：<.path h stacktrace: newtonsoft.json.jsontextreader.parsevalue newtonsoft.json.jsontextreader.read newtonsoft.json.serialization.jsonserializerinternalreader.readfortype hasconverter at newtonsoft.json.serialization.jsonserializerinternalreader.deserialize objecttype checkadditionalcontent newtonsoft.json.jsonserializer.deserializeinternal microsoft.rest.serialization.safejsonconvert.deserializeobject json microsoft.bot.connector.conversations.d__6.movenext parsevalue>

有什么帮助吗？

编辑：这就是我反序列化对象的方式。

  HttpContent requestContent = Request.Content;
            string jsonContent = requestContent.ReadAsStringAsync().Result;
            List<ConversationModel> model = new List<ConversationModel>();


            try { 
            model = JsonConvert.DeserializeObject<List<ConversationModel>>(jsonContent);

这是我的对象内容：

 channelId: "emulator"
    conversationId: "a0m69i29gih3kjf3mc"
    email: "some-email@hotmail.com"
    fromId: "49gjgijl7a4inc821c"
    fromName: ""
    serviceUrl: "http://localhost:3979"
    toId: "default-user"
    toName: ""

我正在为本地测试显式添加 name 和 from name（请参阅代码）。

Answer 1

这里有IsGroup 和Name 属性设置为null：

message.Conversation {Microsoft.Bot.Connector.ConversationAccount} ID： "a0m69i29gih3kjf3mc" IsGroup: null 名称: null

尝试为这些属性赋值。

这里也可能发生错误：

if (botAccount.Name == "")
  botAccount.Name = "Bot";
if (userAccount.Name == "")
  userAccount.Name = "User";  

如果是null 对象（当botAccount.Name = null 或userAccount.Name = null 时），使用string == "" 检查字符串是否为空将失败。
尝试改用string.IsNullOrEmpty()：

if (string.IsNullOrEmpty(botAccount.Name))
  botAccount.Name = "Bot";
if (string.IsNullOrEmpty(userAccount.Name))
  userAccount.Name = "User";
