直到最近才开始使用SignalR,我几天前就已经开始工作,现在无法解决出错的问题.

我有我的中心:

[HubName("roleManagementHub")]
public class RoleManagementHub : GenericHub<RoleManagementRole>
{
    public RoleManagementHub(ICurrentlyViewingUserService service) : base(service)
    {
    }
}

这扩展了我创建的通用集线器:

public class GenericHub<TEntity> : Hub where TEntity : class, IBusinessObject<TEntity>
{
    private readonly ICurrentlyViewingUserService service;

    public GenericHub(ICurrentlyViewingUserService service)
    {
        this.service = service;
    }

    public void ImViewing(string id)
    {
        string colour;
        service.AddCurrentlyViewingUser<TEntity>(id, HttpContext.Current.User.Identity.Name, out colour);
        Clients.handleImViewingMessage(HttpContext.Current.User.Identity.Name, colour, id);
    }

    public void ImLeaving(string id)
    {
        service.RemoveCurrentlyViewingUser<TEntity>(id, HttpContext.Current.User.Identity.Name);
        Clients.handleImLeavingMessage(HttpContext.Current.User.Identity.Name, id);
    }

    public void IHaveEdited(string id, string property, string content)
    {
        string colour = service.GetCurrentlyViewingUserColour<TEntity>(id, HttpContext.Current.User.Identity.Name); …
