一、接口寫法

namespace WebApplication1.Controllers.Redis
{[ApiController][Route("/api/[controller]")]public class RedisService : IRedisService{private readonly IConnectionMultiplexer _redis;//StackExchange.Redis庫自帶接口public RedisService(IConnectionMultiplexer redis){_redis = redis;}// 異步增加鍵值對[HttpPost("set")]public async Task<bool> SetAsync(string key, string value){var db = _redis.GetDatabase();bool result = await db.StringSetAsync(key, value);return result;}// 異步刪除鍵值對[HttpDelete("remove")]public async Task<bool> RemoveAsync(string key){var db = _redis.GetDatabase();bool result = await db.KeyDeleteAsync(key);return result;}// 異步查詢鍵值對[HttpGet("get")]public async Task<object> GetAsync(string key){var db = _redis.GetDatabase();var value = await db.StringGetAsync(key);if (value.HasValue){return new { Key = key, Value = value.ToString() };}return new { Message = $"Key {key} not found." };}// 異步清空所有緩存[HttpPost("flushall")]public async Task<bool> FlushAllAsync(){var server = _redis.GetServer("localhost", 6379);  // 替換為你的 Redis 服務器 IP 和端口await Task.Run(() => server.FlushAllDatabases());  // 異步執行清空操作return true;}}
}

二、Startup.cs配置

public void ConfigureServices(IServiceCollection services)
{//省略其他代碼// 注入自己寫的服務實例services.AddTransient<IRedisService, RedisService>();// 配置 Redis 連接 （ConnectionMultiplexer 是 StackExchange.Redis自帶的）var redisConnection = ConnectionMultiplexer.Connect("localhost:6379,defaultDatabase=1,allowAdmin = true");  // 替換成你實際的 Redis 連接字符串services.AddSingleton<IConnectionMultiplexer>(redisConnection);}
