signalr服务端-基础搭建

signalr 支持 iis托管、winform、windowsservices、wpf 托管 这里我采用winfrom托管

首先画一个这样的窗体

在服务项目通过项目管理包安装signalr类库

安装后 如果客户端是web程序 则将js移动到客户端 编写客户端的时候使用

这次我安装缺少一个 程序集 我在官网下载手动引用上去了

新建一个类 该类用于自定义找到signalr回话的id  默认是随机的一个guid维护。。实现这个类 就可以根据用户id 直接发送给指定用户

  /// <summary>
    /// 自定义维护每个用户会话id的实现类
    /// </summary>
    public class UserIdProvider:IUserIdProvider
    {
        public string GetUserId(IRequest request)
        {
            return request.QueryString["Uid"];
        }
    }

新建一个signalr启动类。并将自定义维护会话注入

 public class Startup
    {
       public void Configuration(IAppBuilder app)
       {
           //注入signlar自定义维护会话id
           GlobalHost.DependencyResolver.Register(typeof(IUserIdProvider), () => new UserIdProvider());
           app.UseCors(CorsOptions.AllowAll);
           app.MapSignalR();
       }
    }

新建一个服务器的在线用户信息管理类

 /// <summary>
    /// 在线用户信息管理类
    /// </summary>
    public class User
    {
        /// <summary>
        /// 用户id
        /// </summary>
        public string Uid { get; set; }

        /// <summary>
        /// 用户名字
        /// </summary>
        public string UName { get; set; }

        /// <summary>
        /// 上线时间
        /// </summary>
        public DateTime Date { get; set; }

        /// <summary>
        /// 头像
        /// </summary>
        public string HeadPath { get; set; }

        /// <summary>
        /// 当前用户所在机构id
        /// </summary>
        public string OrganId{ get; set; }

        /// <summary>
        /// 当前用户所在部门id
        /// </summary>
        public string Depid { get; set; }
    }

引入redis客户端 消息队列管理以及在线用户管理

编写接口层 如果不使用redis可以切换成其他存储

 public interface IDeposit
   {
       Task<bool> RemoveKey(string key);
       Task<bool> SetAsync(string key, object value, TimeSpan? timeOut = null);
       Task<T> GetAsync<T>(string key);
       Task<bool> ListLeftPush(string key, object value, TimeSpan? ts = null);
       Task<bool> ListRightPush(string key, object value, TimeSpan? ts = null);
       Task<T> ListLeftPop<T>(string key);

       Task<T> ListRightPop<T>(string key);

       bool HashSet(string keyA, string keyB, object value);

       T HashGet<T>(string keyA, string keyB);
   }
}

编写实现层

  public class RedisManager:IDeposit
    {
        private  ConnectionMultiplexer _redis;
        private  object _locker = new object();
        public  ConnectionMultiplexer Manager
        {
            get
            {
                if (_redis == null)
                {
                    lock (_locker)
                    {
                        if (_redis != null) return _redis;
                        _redis = GetManager();
                        return _redis;
                    }
                }
                return _redis;
            }
        }

        public  IDatabase DB
        {
            get
            {
                return Manager.GetDatabase();
            }

        }

        private  ConnectionMultiplexer GetManager()
        {
            ConfigurationOptions co = new ConfigurationOptions()
            {
                EndPoints =
                     {
        {ConfigHelper.GetRedisIp, ConfigHelper.GetRedisPort }
    }
            };

            return ConnectionMultiplexer.Connect(co);
        }

        public async  Task<bool> RemoveKey(string key)

        }

            {

                isOk = Manager.GetDatabase().StringSet(key, str);

            }
            else
            {
                isOk = Manager.GetDatabase().StringSet(key,value.ToString());
            }

            //设置key的失效时间
             if (isOk && timeOut != null)
             {

编写帮助类

 public class DepositHelper

       public static IDeposit rm = new RedisManager();

            return rm.RemoveKey(key);
        }

        public static  Task<bool> SetAsync(string key, object value, TimeSpan? timeOut = null)
        {
            return rm.SetAsync(key, value, timeOut);
        }

        public static  Task<T> GetAsync<T>(string key)
        {
            return rm.GetAsync<T>(key);
        }

        public static  Task<bool> ListLeftPush(string key, object value, TimeSpan? ts = null)
        {

       {
           return rm.HashSet(keyA, keyB, value);
       }

       public static T HashGet<T>(string keyA, string keyB)
       {
           return rm.HashGet<T>(keyA, keyB);
       }

    }

编写在线用户信息管理类

以后再写了
