StackExchange.Redis.RedisConnectionException

Question

我试图使用Redis作为黑名单JWT的缓存，以实现JWT的注销。我已经在我的windows 10机器上下载了redis并运行了"redis-server.exe"，它说：

   [6112] 28 Nov 16:28:51.791 # Warning: no config file specified, using the default config. In order to specify a config file use redis-server /path/to/redis.conf

[6112] 28 Nov 16:28:51.798 # Server started, Redis version 3.0.504
[6112] 28 Nov 16:28:51.799 * DB loaded from disk: 0.001 seconds
[6112] 28 Nov 16:28:51.800 * The server is now ready to accept connections on port 6379

     Redis 3.0.504 (00000000/0) 64 bit
    
        Running in standalone mode
    
     The server is now ready to accept connections on port 6379

这表明它工作正常。

我使用的是.NetCore 3.1，并且安装了Microsoft.Extensions.Caching.Redis v2.2.0NuGET包。

在我的startup.cs中，我添加了

services.AddDistributedRedisCache(r =>
            {
                r.Configuration = Configuration["Redis:ConnectionString"];
            });

在我的appsettings.json里

 "Redis": {
    "ConnectionString": "localhsot"
  }

但是，在我发送的任何请求中，我都会得到以下例外：

StackExchange.Redis.RedisConnectionException: It was not possible to connect to the redis server(s); to create a disconnected multiplexer, disable AbortOnConnectFail. SocketFailure on PING
   at StackExchange.Redis.ConnectionMultiplexer.ConnectAsync(String configuration, TextWriter log) in c:\code\StackExchange.Redis\StackExchange.Redis\StackExchange\Redis\ConnectionMultiplexer.cs:line 801
   at Microsoft.Extensions.Caching.Redis.RedisCache.ConnectAsync(CancellationToken token)
   at Microsoft.Extensions.Caching.Redis.RedisCache.GetAndRefreshAsync(String key, Boolean getData, CancellationToken token)
   at Microsoft.Extensions.Caching.Redis.RedisCache.GetAsync(String key, CancellationToken token)
   at Microsoft.Extensions.Caching.Distributed.DistributedCacheExtensions.GetStringAsync(IDistributedCache cache, String key, CancellationToken token)

我做错什么了？我为什么要得到这个例外？？顺便说一下，我正在学习取消JWT上的这个教程

我不敢相信我会这么说，但事实证明，导致这一异常的原因是连接字符串。我没有输入"localhost"，而是输入了"localhsot"。一旦我修好了，一切都如期而至。
