SignalR .Net客户端在设备上出现500服务器错误,模拟器工作正常

标签: c# ios asp.net xamarin signalr

我试图在我的应用中实现聊天,后端使用azure asp.net web api,前端使用xamarin ios。

所以在后端我使用以下行配置我的集线器:

        var hubConfiguration = new HubConfiguration();
        hubConfiguration.EnableDetailedErrors = true;
        app.MapSignalR("/signalr", hubConfiguration);

这是我的中心来源:

[HubName("Chat")]
public class Chat : Hub
{

    public Task JoinRoom(string roomName)
    {
        return Groups.Add(Context.ConnectionId, roomName);
    }

    public Task LeaveRoom(string roomName)
    {
        return Groups.Remove(Context.ConnectionId, roomName);
    }

    public Task Send(string message, string room)
    {
        return Clients.OthersInGroup(room).addMessage(message);
    }
}

在xamarin ios客户端上一切都很简单:

[Preserve(AllMembers=true)]
public class Msg
{
    public string txt { get; set; }
}

public class Client
{
    private readonly string _userName;
    private readonly HubConnection _connection;
    private readonly IHubProxy _proxy;

    public event EventHandler<string> OnMessageReceived;

    public Client(string userName)
    {
        _userName = userName;
        _connection = new HubConnection("http://mywebsite.azurewebsites.net/");
        _connection.ConnectionToken = NetManager.Instance.token.access_token;
        _proxy = _connection.CreateHubProxy("Chat");
    }

    public async Task Connect()
    {

        await _connection.Start();

        _proxy.On("messageReceived", (Msg platform, Msg message) =>
            {
                if (OnMessageReceived != null)
                    OnMessageReceived(this, string.Format("{0}: {1}", platform, message));
            });

        Send("Connected");
    }

    public Task Send(string message)
    {
        return _proxy.Invoke("Send", _userName, message);
    }
}

因此,如果我从ios模拟器连接到服务器 - 它工作正常,但是当我尝试从我的ipad设备执行此操作时 - 它会在线上崩溃内部服务器错误(&#39;等待_connection.Start() ;&#39)

我已经使用调试器检查了服务器,但没有异常,并且日志清晰。

任何想法如何解决这个问题都会非常有用!

[ UPD ] 一些新的服务器日志:

所以,不知何故,不知道为什么设备发送空组名称 (1):[%7B%22Name%22:%22chat%22%7D] (2):[%7B%7D]

看起来像json序列化器问题,但我该如何解决?

1 个答案:

答案 0 :(得分:3)

终于明白了,这是因为所有&#39;设备构建选项中的选项,因此json不能正常工作
