SignalR中的AllowAnonymous属性 [英] AllowAnonymous attribute in SignalR

问题描述

[Authorize] // Derived from Microsoft.AspNet.SignalR.Authorize
public class ChatHub : Hub
{
    [System.Web.Mvc.AllowAnonymous] // [AllowAnonymous] doesn't be supported here
    public async Task GetEmails()
    {
        using (var db = new MyDbContext())
        {
            var users = await db.Users.ToListAsync();
            var emails = new List<string>();
            users.ForEach(x => emails.Add(x.Email));
            Clients.All.getEmails(JsonConvert.SerializeObject(emails));
        }
    }
}

我的问题:我将断点设置为 GetEmails 方法，但从未实现.然后，我登录并再次尝试，它正在工作.

My problem: I'd set breakpoint to GetEmails method but it's never hit to. Then, I signed in and tried again, it's working.

这意味着: [System.Web.Mvc.AllowAnonymous] 在 [Microsoft.AspNet.SignalR.Authorize] 中不起作用.

That means: [System.Web.Mvc.AllowAnonymous] doen't work within [Microsoft.AspNet.SignalR.Authorize].

所以，我的问题是:为什么命名空间 Microsoft.AspNet.SignalR 不支持 [AllowAnonymous] 属性?我是否需要为此声明 AllowAnonymous 属性?

So, my question is: Why doesn't namespace Microsoft.AspNet.SignalR support [AllowAnonymous] attribute? And do I need to declare AllowAnonymous attribute for that?

推荐答案

我已经解决了问题:使用 [System.Web.Mvc.Authorize] 代替 [Authorize] .像这样:

I've solved the problem: Using [System.Web.Mvc.Authorize] instead of [Authorize]. Like this:

[System.Web.Mvc.Authorize] 
public class ChatHub : Hub
{
    [System.Web.Mvc.AllowAnonymous] 
    public async Task GetEmails()
    {
        // ...
    }
}

我不明白为什么，但是它应该可以很好地工作:)

I don't understand why but it should work perfectly :)
