C# Redis消息队列例子2

  

• 2 创建类

创建接口IRedisCache.cs和RedisCache.cs

在WeatherForestcastController中构造函数注入，然后测试 

        [HttpGet]
        public IEnumerable<WeatherForecast> Get()
        {
            var rng = new Random();
         //   _redisCache.stringSet("test01","test01",TimeSpan.FromHours(5));
 
            WeatherForecast weatherForecast = new WeatherForecast();
            weatherForecast.Date = DateTime.Now;
            weatherForecast.TemperatureC = rng.Next(-20, 55);
            weatherForecast.Summary = Summaries[rng.Next(2)];
            var value=_redisCache.publish("redisChat",weatherForecast);
          
            var tt= Enumerable.Range(1, 5).Select(index => new WeatherForecast
            {
                Date = DateTime.Now.AddDays(index),
                TemperatureC = rng.Next(-20, 55),
                Summary = Summaries[rng.Next(Summaries.Length)]
            })
            .ToArray();
 
            return tt;
 
        }
