redis 使用

修改配置文件

修改 appsettings.json 配置文件

//redis服务配置
"RedisServer": {
	"open": 1, //redis初始化开关（默认0）
	"Cache": "127.0.0.1:6379,defaultDatabase=0,poolsize=50,ssl=false,writeBuffer=10240,prefix=cache:",//用于缓存
	"Session": "127.0.0.1:6379,defaultDatabase=0,poolsize=50,ssl=false,writeBuffer=10240,prefix=session:"//用户登录会话管理
	//...其他
}

使用

使用 RedisServer.Cache.Set("test", "hello");

注意引用：using ZR.Common.Cache

缓存监控

替换MonitorController控制器中的GetCache方法

/// <summary>
/// 获取缓存监控数据
/// </summary>
/// <returns></returns>
[HttpGet("monitor/cache")]
public IActionResult GetCache()
{
    //已连接的客户端item1 当前redisIP，item2已连接的客户端列表
    //(string, string)[] val = RedisServer.Cache.NodesServerManager.ClientList();

    //获取当前数据库的key总量
    (string, long)[] dbSize = RedisServer.Cache.NodesServerManager.DbSize();

    //(string, string)[] names = RedisServer.Cache.NodesServerManager.ClientGetName();
    (string, string)[] infos = RedisServer.Cache.NodesServerManager.Info();
    (string, string)[] commandStats = RedisServer.Cache.NodesServerManager.Info(CSRedis.InfoSection.CommandStats);

    var info = infos[0].Item2.Split("\r\n", StringSplitOptions.RemoveEmptyEntries);
    var commandStat = commandStats[0].Item2.Split("\r\n", StringSplitOptions.RemoveEmptyEntries);

    Dictionary<string, object> infoDic = new();
    List<Dictionary<string, object>> commandStatDic = new();

    foreach (var item in info)
    {
        var obj = item.Split(":", StringSplitOptions.RemoveEmptyEntries);
        if (obj.Length > 1)
        {
            infoDic.Add(obj[0], obj[1]);
        }
    }
    foreach (var item in commandStat)
    {
        var obj = item.Split(":", StringSplitOptions.RemoveEmptyEntries);
        Dictionary<string, object> data = new();
        if (obj.Length > 1)
        {
            data.Add("name", obj[0].Replace("cmdstat_", ""));
            data.Add("value", SubstringBetween(obj[1], "calls=", ",usec="));
            commandStatDic.Add(data);
        }
    }
    return SUCCESS(new
						{
								dbSize = dbSize[0].Item2,
								commandStats = commandStatDic,
								info = infoDic
								});
}
