c# - 无论如何，是否可以在 azure 函数中使用 AddSecretClient DI 扩展？

Question

我正在尝试为我的 azure 功能配置一些依赖项。我需要能够访问(除其他外)一个 azure 的 keystore 。目前，我正在手动访问它，并且必须自己完成所有依赖项注入(inject)。这感觉不对，我开始寻找更好的方法来连接它。我发现this blog这看起来很理想。

public void ConfigureServices(IServiceCollection services)
{
  services.AddAzureClients(builder =>
  {
    // Add a KeyVault client
    builder.AddSecretClient(keyVaultUrl);

    // Add a storage account client
    builder.AddBlobServiceClient(storageUrl);

    // Use the environment credential by default
    builder.UseCredential(new EnvironmentCredential());
  });

  services.AddControllers();
}

太棒了，我想这么做。问题是这些扩展似乎不支持 Azure 函数中实现的特定 DI。具体来说，AddSecretClient 的预期类型与注入(inject) Configure(IFunctionsHostBuilder builder) 的构建器之间存在不兼容:

[assembly: FunctionsStartup(typeof(Startup))]
namespace Snapshot.Take
{
    [ExcludeFromCodeCoverage]
    public class Startup : FunctionsStartup
    {
        

        public override void Configure(IFunctionsHostBuilder builder)
        {
            RegisterHttpClients(builder);

            builder.Services.AddLogging();

            //error

            builder.AddSecretClient(new Uri(""));
       }
   }
}

The type'Microsoft.Azure.Functions.Extensions.DependencyInjection.IFunctionsHostBuilder'cannot be used as type parameter 'TBuilder' in the generic type ormethod'SecretClientBuilderExtensions.AddSecretClient(TBuilder,Uri)'. There is no implicit reference conversion from'Microsoft.Azure.Functions.Extensions.DependencyInjection.IFunctionsHostBuilder'to 'Azure.Core.Extensions.IAzureClientFactoryBuilderWithCredential'.

这些扩展是否有 Azure 函数版本，还是我必须自己推出？

由于 AddAzureClients 是 IServiceCollection 上的扩展方法，您可能需要执行以下操作:

  builder.Services.AddAzureClients(clientBuilder =>
  {
    // Add a KeyVault client
    clientBuilder.AddSecretClient(keyVaultUrl);

    // Add a storage account client
    clientBuilder.AddBlobServiceClient(storageUrl);

    // Use the environment credential by default
    clientBuilder.UseCredential(new EnvironmentCredential());
  });
