3.2.4 Utility.cs 基础配置
满足时钟、获取QRCode等
using TxSms.Actions;namespace TxSms.SingalR { internal class Utility { public static int IntNum = 0; /// <summary> /// 时间间隔 /// </summary> /// <returns></returns> public static int TimerValue() { return 1000; } public static double ActivityTimerInterval() { return 1000.0; } /// <summary> /// 获取当前UUID /// </summary> /// <returns></returns> public static string GetUUID(string connectionId) { try { var model = new QRCodeAction().GetValidModel(connectionId); return model.ToJson(connectionId); } catch { return "ERROR"; } } /// <summary> /// 删除过期UUID /// </summary> public static void ClearExpiredUUID() { IntNum++; if (IntNum <= 1000) return; new QRCodeAction().ClearExpiredUUID(); IntNum = 0; } }}
3.2.5 SignalR在MVC中启动配置
在MVC中，启动项目进行如下配置：
