ABP Redis 与 RedisClient 相互读取

本文说明的是 ABP 封装的Redis 和 安装客户端ServiceStack.Redis.RedisClient 互相读取数据

 

 

 我为什么会用到这个需求呢，原因是独立出的服务要往redis写数据，发现写进去了，ABP框架的WebApi读取不到我写的KEY，根据客户端验证发现他前面带入了n:key,c:key

所以我写入的时候也默认加上了n:,c: 如下代码

 

        public void readis(Dictionary<string, IList<HardDiskPartition>> redis, string key)
        {
            ServiceStack.Redis.RedisClient client = new ServiceStack.Redis.RedisClient("127.0.0.1", 6379);
            //ServiceStack.Redis.RedisClient client = new ServiceStack.Redis.RedisClient("60.251.129.78", 6379);
            client.Db = 4;
            ////读取
            Dictionary<string, IList<HardDiskPartition>> ComputerService = null;
            string json = client.Get<string>("n:ComputerService,c:ComputerService");
            ABPRedis json2 = client.Get<ABPRedis>("n:ComputerService,c:ComputerService");
            //ComputerService = client.Get<Dictionary<string, IList<HardDiskPartition>>>("n:ComputerService,c:ComputerService");
            //var a  = client.Get<object>("n:yesterDayAdd,c:yesterDayAdd");


            if (json2 != null && json2.Payload != null)
            {
                ComputerService = JsonConvert.DeserializeObject<Dictionary<string, IList<HardDiskPartition>>>(json2.Payload.ToString());
            }
            if (ComputerService != null)
            {
                if (ComputerService.Keys.Contains(key))
                {
                    ComputerService[key] = redis[key];
                }
                else
                {
                    ComputerService.Add(key, redis[key]);
                }
            }
            else
            {
                ComputerService = redis;
            }
            //string pwd = client.Get<string>("password");
            //存储
            var result = JsonConvert.SerializeObject(ComputerService);
            // 这样写的原因是 因为ABP 读取的时候是读取 Payload 的值 不封装的话 webapi读取不到
            var obj888 = new
            {
                Payload = result,
                Type = "System.Collections.Generic.Dictionary`2[[System.String, System.Private.CoreLib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e],[System.Collections.Generic.IList`1[[GetComputerService.HardDiskPartition, GetComputerService, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]], System.Private.CoreLib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e]], System.Private.CoreLib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e"

            client.Set("n:ComputerService,c:ComputerService", obj888);

        }

                {
                    return true;
                }
                else

代码中写入了一个匿名对象，原因是为了abp webapi读取的时候能去解PayLoad 里面的数据， 至于下面的Type 不会写的人可以在ABPWebApi中的redis去写入进去，然后复制写死，因为类型是不会变的。这样弄的原因是采用同样的数据类型ABPRedis会自动帮你直接转换数据。 获取里面的值如下代码：

 new
            {
                Payload = result,
                Type = "System.Collections.Generic.Dictionary`2[[System.String, System.Private.CoreLib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e],[System.Collections.Generic.IList`1[[GetComputerService.HardDiskPartition, GetComputerService, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]], System.Private.CoreLib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e]], System.Private.CoreLib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e"
            };

    public Dictionary<string, IList<HardDiskPartition>> ComputerService()
        {
            //Dictionary<string, IList<HardDiskPartition>> obj = new Dictionary<string, IList<HardDiskPartition>>
            //{
            //    ["台湾78"] = new List<HardDiskPartition>()
            //    {
            //         new HardDiskPartition
            //         {
            //              FreeSpace=0,
            //               PartitionName="xxxxxxxx",
            //                SumSpace=1,
            //                 UpdateTime=DateTime.Now.ToShortDateString()
            //         }
            //    }
            //};
            //_cacheManager.GetCache("ComputerService10").Set("ComputerService10", obj);
           return (Dictionary<string, IList<HardDiskPartition>>)_cacheManager.GetCache("ComputerService").GetOrDefault("ComputerService");
          }

上面代码中注释掉的部分是上面说到的 用ABPRedis 封装好的写入数据进去，好用redis可视化工具去查看到Type的值，方便复制。

为什么读取的时候不加上n:,c: 因为默认是加了的 所以只用写ComputerService 就好

 

 

 

 

总结：ABP的redis默认是在写入key的时候给你的key加了n:,c:  并且写入数据的时候多加了个对象，对象属性为：Payload 和 Type
