使用rbac服务主体进行身份验证导致403访问群体验证失败。观众不匹配

我正在尝试授予应用程序对blob存储容器的访问权限，但具有所需的最低权限（读/写）

使用azure cli，我已完成以下步骤来尝试此操作：

az group create -l ${LOCATION} -n ${RESOURCE_GROUP_NAME}

az role definition create --role-definition rw-blob-role.json

rw-blob-role.json:
{
  "assignableScopes": [
    "/subscriptions/{{SUBSCRIPTION_ID}}"
  ],
  "description": "Custom role to allow for read and write access to Azure Storage blob containers and data",
  "name": "{{APP_RW_ROLE_NAME}}",
  "permissions": [
    {
      "actions": [
        "Microsoft.Storage/storageAccounts/blobServices/containers/read",
        "Microsoft.Storage/storageAccounts/blobServices/containers/write"
      ],
      "dataActions": [
        "Microsoft.Storage/storageAccounts/blobServices/containers/blobs/read",
        "Microsoft.Storage/storageAccounts/blobServices/containers/blobs/write"
      ],
      "notActions": [],
      "notDataActions": []
    }
  ],
  "type": "Microsoft.Authorization/roleDefinitions"
}


az ad sp create-for-rbac --name ${AZ_SERVICE_PRINCIPAL_NAME} --password ${APP_CLIENT_SECRET}

az role assignment delete --assignee ${AZ_SERVICE_PRINCIPAL_NAME} --role Contributor

az role assignment create --assignee ${AZ_SERVICE_PRINCIPAL_NAME} --role ${APP_RW_ROLE_NAME}

az storage account create --name ${STORAGE_ACCOUNT_NAME} --resource-group ${RESOURCE_GROUP_NAME} --location ${LOCATION} --kind BlobStorage --sku ${STORAGE_ACCOUNT_SKU} --access-tier ${STORAGE_ACCOUNT_ACCESS_TIER}

az storage container create --name ${BLOB_STORAGE_CONTAINER} --account-name ${STORAGE_ACCOUNT_NAME} --public-access off

在此基础上，我保存以下属性供我的应用程序使用：
-租户ID=“$（az帐户显示--输出tsv--查询租户ID）”
-CLIENT_ID=“$（az ad sp list--spn${az_SERVICE_PRINCIPAL_NAME}--输出tsv--query[0].appId）”
-客户端密码：${APP\u Client\u secret}
-资源：${AZ_服务_主体_名称}
-存储帐户名称：${Storage\u Account\u name}
-容器名称：${BLOB\U存储\U容器}

我使用com.microsoft.azure:adal4j获取令牌：

public AuthenticationResult getToken() {
    ExecutorService service = Executors.newFixedThreadPool(1);
    ClientCredential credential = new ClientCredential(CLIENT_ID, APP_CLIENT_SECRET);
    String authorityTenantUrl = String.format(https://login.microsoftonline.com/%s/oauth2/token, TENANT_ID);

    AuthenticationContext context;
    AuthenticationResult result;
    try {
      context = new AuthenticationContext(authorityTenantUrl, true, service);
      Future<AuthenticationResult> future = context.acquireToken(AZ_SERVICE_PRINCIPAL_NAME, credential, null);
      result = future.get();
    } catch (Exception e) {
      throw new RuntimeException(e);
    } finally {
      service.shutdown();
    }

    if (result == null) {
      throw new RuntimeException("authentication result was null");
    }

    return result;
}

这会导致StorageException：

<Error>
  <Code>AuthenticationFailed</Code>
  <Message>Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature.</Message>
  <AuthenticationErrorDetail>Audience validation failed. Audience did not match.</AuthenticationErrorDetail>
</Error>

我很确定问题在于acquireToken（）上传递给adal4j的AZ_服务_主体_名称，但我不知道正确的值是什么。我已尝试在租户广告和服务负责人上使用客户ID和其他属性。

您应该使用

https://storage.azure.com/

获取资源的价值

<Error>
  <Code>AuthenticationFailed</Code>
  <Message>Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature.</Message>
  <AuthenticationErrorDetail>Audience validation failed. Audience did not match.</AuthenticationErrorDetail>
</Error>
