对于管理匿名用户SignalR连接 [英] Managing SignalR connections for Anonymous user

问题描述

我使用SignalR版本2.1.2与ASP.Net MVC 5安培; NServiceBus并具有下列要求

I am using SignalR version 2.1.2 with ASP.Net MVC 5 & NServiceBus and have following requirement

有是在SignalR用于发送通知的注册页面（匿名认证）。每个表单提交将产生一个新的连接ID它需要保持一个集合中，这样我可以发送响应到客户端。 Context.User.Identity.Name是空的，因此_connections.Add（姓名，Context.ConnectionId）;不能在OnConnected（）枢纽事件在此的帖子

There is a signup page (anonymous authentication) in which SignalR is used to send notifications. Every form submit will generate a new connection id which needs to be kept in a collection so that I can send response to the client. Context.User.Identity.Name is empty hence _connections.Add(name, Context.ConnectionId); cannot be used in OnConnected() hub event as given in this post

类似的问题。

如果有一个可能控制的ConnectionId然后我可以克服这种情况，但它看起来像SignalR新版本已经摆脱了连接工厂。

If there is a possibility to control the ConnectionId then I could overcome this situation but it looks like new version of SignalR has got rid of connection factory.

我使用Redis的缓存，这样一个选择是写我自己的连接管理代码保持这些连接ID在里面。

I am using Redis cache so one option is to write my own connection management code to keep these connection ids in it.

第二个选择是使用窗体身份验证以这样的方式，一个匿名角色分配给这些用户制约了使用匿名查看/控制器，反而给人一种名称的用户，这样Context.User.Identity.Name不为空。有了这个，我可以使用内置的SignalR机制来管理连接ID我。

Second option is to use Forms Authentication in such a way that a 'Anonymous Role' is assigned to these users which restricts the usage to anonymous views/controllers but gives a 'Name' to the user so that Context.User.Identity.Name is not empty. With this I can use built in SignalR mechanism to manage connection ids for me.

推荐答案

使用表单验证，存储联合Cookie和存储在cookie中的枢纽地区以及..
在SignalR jQuery代码，使用jQuery插件读取的HTTP cookie，并得到该地区的名称和订阅通知。

Use Forms Authentication, store a Federated Cookie and store the hub region in the cookie as well.. In SignalR jQuery code, use a jQuery plugin to read HTTP cookie and get the region name and subscribe to notifications.

另外，在你的.cshtml，jQuery的渲染与您的视图模型填充区域

Alternatively, in your .cshtml, render jQuery with region populated from your View Model.

注意：使用 FormsAuthentication.SetAuthCookie ，因为这将创建HTTP cookie的唯一并会在Ajax和非Ajax调用发送。

Note: Use FormsAuthentication.SetAuthCookie as this will create HTTP Only cookie and will be sent in Ajax and non-Ajax calls.
