.Net客户端在设备上发生了500个服务器错误，在模拟器上运行良好

时间：2021-09-21 18:21:48

I'm trying to implement a chat in my app, with azure asp.net web api on back-end and xamarin ios on front-end.

我想在我的app中实现聊天，azure asp.net web api在后端，xamarin ios前端。

So on back-end I configure my hub with this lines:

在后端，我用这几行来配置我的中心:

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

and here is my hub source:

这是我的hub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);
    }
}

on xamarin ios client everything is pretty simple too:

在xamarin ios客户端，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);
    }
}

So if I connect to server from ios simulator -- it works fine, but when I try to do this from my ipad device -- it crashes with internal server error on line ('await _connection.Start();')

因此，如果我从ios模拟器连接到服务器——它运行得很好，但是当我尝试从我的ipad设备上进行连接时——它会在网络上由于内部服务器错误而崩溃(' wait _connect . start ();')

I have already checked server with debugger, but no exceptions raised there, and logs are clear.

我已经用调试器检查了服务器，但是没有出现异常，日志也很清楚。

Any ideas how to fix this will be very helpful!

任何解决这个问题的方法都将非常有用!

So somehow, don't know why from device sends empty group name (1) :[%7B%22Name%22:%22chat%22%7D] (2) :[%7B%7D]

因此，不知何故，不知道为什么从设备发送空组名称(1):[%7B%22:%22:%22 %22% 22:%22 %22:%22 %22:%22 %22:%22 %22:%22 %22:%22 %22:%22 %22% 22:%22 %22% 22% 2

Seems like json serializer problem, but how can I fix that?

看起来像json序列化器的问题，但是我怎么解决呢?

finally got it, it was because of 'link all' option in device build options, so json didn't work well

最终得到它，是因为“链接所有”选项在设备构建选项中，所以json没有很好地工作
