SignalR服务器错误"ConnectionId的格式不正确." 使用SignalR-ObjC库

Question

在问一个单独的问题之前,我已经做了很多关于它的谷歌搜索并在已经存在的stackoverflow 问题中添加了注释.

我在我的服务器中有一个SignalR Hub(试过v.1.1.3和2.0.0-rc),代码如下:

    [HubName("TestHub")]
    public class TestHub : Hub
    {
            [Authorize]
            public void TestMethod(string test)
            {
                //some stuff here
                Clients.Caller.NotifyOnTestCompleted();
            }
    }

如果我删除Authorize属性,问题仍然存在.

在我的iOS客户端中,我尝试使用以下代码调用它:

    SRHubConnection *hubConnection = [SRHubConnection connectionWithURL:_baseURL];
    SRHubProxy *hubProxy = [hubConnection createHubProxy:@"TestHub"];
    [hubProxy on:@"NotifyOnTestCompleted" perform:self selector:@selector(stopConnection)];

    hubConnection.started = ^{
        [hubProxy invoke:@"TestMethod" withArgs:@[@"test"]];
    };

    //received, error handling
    [hubConnection start];

当应用程序启动时,用户未登录,并且没有打开SignalR连接.用户通过调用服务器中的登录服务来登录,该服务使用WebSecurity.Login方法.如果登录服务返回成功,则我对SignalR Hub进行上述调用,我得到服务器错误500,其描述为"ConnectionId的格式不正确".

完整的服务器堆栈跟踪如下:

我知道这是某种身份验证和用户身份不匹配,但到目前为止我还没有办法解决它.所有其他问题建议在用户身份更改时停止打开的连接,但正如我上面提到的,在用户成功登录之前我没有打开连接.

任何帮助将非常感激.谢谢.

我们也有类似的问题。关闭连接令牌的加密功能修复了它。

抱歉，我无法提供进一步的帮助，因为我正在 iOS 端工作，而不是 .net 端。
