}在此目录新建secrets01.yaml定义storeapiVersion: dapr.io/v1alpha1

}运行Frontenddapr run --dapr-http-port 3501 --app-port 5001 --app-id frontend dotnet .\FrontEnd\bin\Debug\net5.0\FrontEnd.dll验证此api获取成功通过IConfiguration访问SecretsDapr还提供了从IConfiguration中访问Secrets的方法首先引入nuget包Dapr.Extensions.Config在Program.cs中修改注册public static IHostBuilder CreateHostBuilder(string[] args) Host.CreateDefaultBuilder(args).ConfigureAppConfiguration(config {var daprClient new DaprClientBuilder().Build();var secretDescriptors new ListDaprSecretDescriptor { new DaprSecretDescriptor(RabbitMQConnectStr) };config.AddDaprSecretStore(secrets01, secretDescriptors, daprClient);}).ConfigureWebHostDefaults(webBuilder {webBuilder.UseStartupStartup().UseUrls(http://*:5001);});在SecretsController注入IConfigurationprivate readonly ILoggerSecretsController _logger;private readonly DaprClient _daprClient;private readonly IConfiguration _configuration;public SecretsController(ILoggerSecretsController logger, DaprClient daprClient, IConfiguration configuration){_logger logger;_daprClient daprClient;_configuration configuration;}在SecretsController中新增接口[HttpGet(get01)]public async TaskActionResult Get01Async(){return Ok(_configuration[RabbitMQConnectStr]);}调用接口获取数据成功其他组件引用SecretsDapr的其他组件同样可以引用Secrets我们以上节RabbitMQBinding为例修改rabbitbinding.yamlapiVersion: dapr.io/v1alpha1
