如何在Azure中使用Azure托管标识。存储。Blob。Blob ServiceClient？

Question

在v11SDK. NET中，我能够使用托管标识令牌来访问Azure blob：

var token = await new AzureServiceTokenProvider().GetAccessTokenAsync("https://storage.azure.com/");
var tokenCredential = new TokenCredential(token);
var storageCredentials = new StorageCredentials(tokenCredential);
var blob = new CloudBlobContainer(new Uri("https://some_storage.blob.core.windows.net/some_container"), storageCredentials);

现在我想切换到v12 SDK，但不知道如何对BlobServiceClient进行同样的操作。

我有一个样本：https://github.com/juunas11/managedidentity-filesharing/blob/8410ed3f3d4061de7d40531c025bf6e474489135/Joonasw.ManagedIdentityFileSharingDemo/Services/AzureBlobStorageService.cs#L80

下面是它如何与Azure一起使用。身份：

client = new BlobServiceClient(
    new Uri($"https://{_options.AccountName}.blob.core.windows.net"),
    new ManagedIdentityCredential());

如果需要在本地运行Azure存储帐户，可以使用自定义TokenCredential，如下所示：https://github.com/juunas11/Joonasw.ManagedIdentityDemos/blob/3501ee6fff416db7349807e588532da5c3dd24b1/Joonasw.ManagedIdentityDemos/Services/DemoService.cs#L45.

自定义令牌证书：https://github.com/juunas11/Joonasw.ManagedIdentityDemos/blob/master/Joonasw.ManagedIdentityDemos/Services/ManagedIdentityStorageTokenCredential.cs.

针对存储仿真程序的使用：

client = new BlobServiceClient("UseDevelopmentStorage=true");
