拒绝连接 - Redis 用于 ASP.Net Core 2.1 中的数据保护密钥

Question

我正在阅读 Microsoft 的这篇文章： https://docs.microsoft.com/en-us/aspnet/core/security/data-protection/implementation/key-storage-providers?view=aspnetcore-2.1

我正在尝试执行以下操作：

    services.AddDataProtection()
        .PersistKeysToRedis(ConnectionMultiplexer.Connect("localhost"));

错误堆栈：

我正在使用 Docker：

redis:
    image: redis:alpine
    container_name: redis
    ports:
      - "6379:6379"

有什么想法吗？

Answer 1

你需要引用容器和端口

services.AddDataProtection()
        .PersistKeysToRedis(ConnectionMultiplexer.Connect("redis:6379"));

我还在配置中添加了 abortConnect=false"

REDIS_CONNECTION_STRING = "redis:6379,abortConnect=false"


var redis = ConnectionMultiplexer.Connect(Environment.GetEnvironmentVariable("REDIS_CONNECTION_STRING"));
services.AddDataProtection().PersistKeysToRedis(redis, "DataProtection-Keys");
