我最近将 Steeltoe 版本从 2.4.3 升级到 3.0.1。进行所需更改后，我的应用程序似乎无法连接到托管在 VMWare Cloud Foundry 中的 Redis。健康检查执行器停机并出现以下错误

RedisConnectionException：无法连接到 redis 服务器。UnableToConnect on localhost:6379/Interactive，Initializing/NotStarted，last：NONE，origin：BeginConnectAsync，未完成：0，last-read：0s 前，last-write：0s 前，keep-alive：60s，状态：Connecting，mgr： 10 个可用的 10 个，最后一次心跳：从不，全球：60283 秒前，v：2.1.58.34321。

我的 Program.cs 如下所示

public static class Program
{
   
    public static void Main(string[] args)
    {
       CreateHostBuilder(args).Build().Run();
    }
    
    public static IHostBuilder CreateHostBuilder(string[] args) =>
        Host.CreateDefaultBuilder(args)
            .AddCloudFoundryConfiguration()
            .ConfigureLogging((builderContext, loggingBuilder) =>
            {
                // Add Serilog Dynamic Logger 
                loggingBuilder.ClearProviders();
                loggingBuilder.AddDynamicSerilog();
            })
            .AddCloudFoundryActuators()
            .ConfigureWebHostDefaults(webBuilder =>
            {
                webBuilder.UseStartup<Startup>();
            });
}

我的 .csproj 如下所示。

<PackageReference Include="Serilog.Sinks.Trace" Version="2.1.0" />
<PackageReference Include="Serilog.Formatting.Compact" Version="1.1.0" />
<PackageReference Include="Steeltoe.Common.Hosting" Version="3.0.1" />
<PackageReference Include="Steeltoe.Extensions.Logging.DynamicSerilogCore" Version="3.0.1" />
<PackageReference Include="Steeltoe.Management.CloudFoundryCore" Version="3.0.1" />
<PackageReference Include="Steeltoe.Extensions.Configuration.CloudFoundryCore" Version="3.0.1" />
<PackageReference Include="Newtonsoft.Json" Version="12.0.3" />
<PackageReference Include="StackExchange.Redis" Version="2.1.58" />
<PackageReference Include="Steeltoe.Connector.ConnectorCore" Version="3.0.1" />

我的 Startup.cs 如下所示。

public class Startup
{
   
    public Startup(IConfiguration configuration, IWebHostEnvironment env)
    {
        Configuration = configuration;
        HostingEnvironment = env;
    }
         
    public IConfiguration Configuration { get; }

    public IWebHostEnvironment HostingEnvironment { get; }
         
    public void ConfigureServices(IServiceCollection services)
    {
        services.AddControllers();
        services.AddRouting(options => options.LowercaseUrls = true);          
       
        // Add StackExchange IConnectionMultiplexer configured from Cloud Foundry
        services.AddRedisConnectionMultiplexer(configuration);
    }
  
    public void Configure(IApplicationBuilder app)
    {
       app.UseRouting();
              
        app.UseEndpoints(endpoints =>
        {
            endpoints.MapControllers();
        });
    }
}

看起来连接器无法从 VCAP_SERVICES 获取凭据，最终默认为 localhost。任何指针为什么会这样？提前致谢

为了从VCAP_SERVICESSteeltoe 3.0 中获取绑定，您还需要将其添加到您的 .csproj 中：

<PackageReference Include="Steeltoe.Connector.CloudFoundry" Version="3.0.1" />
