AzureStorage：服务器未能对请求进行身份验证。确保 Authorization 标头的值正确形成，包括签名

Question

我几乎浏览了与此论坛和其他论坛相关的所有 SO 答案，但我仍然无法弄清楚实际问题。此应用是控制台应用，将部署在 On-Premise 环境中，并将文件上传到 Azure blob。

我正在使用带有以下代码的 WindowsAzure.Storage 9.3.3。

static void CreateBlob(string accountName, string containerName, string blobName, string accessToken)
{
        var tokenCredential = new TokenCredential(accessToken);
        var storageCredentials = new StorageCredentials(tokenCredential);
        var storageAccount = new CloudStorageAccount(storageCredentials, accountName, string.Empty, useHttps: true);
        var cloudBlobClient = storageAccount.CreateCloudBlobClient();

        var cloudBlobContainer = cloudBlobClient.GetContainerReference(containerName);
        CloudBlockBlob blockBlob = cloudBlobContainer.GetBlockBlobReference(blobName);

        string blobContents = "Blob created by Azure AD authenticated user.";
        byte[] byteArray = Encoding.ASCII.GetBytes(blobContents);

        try
        {
            using (MemoryStream stream = new MemoryStream(byteArray))
            {
                blockBlob.UploadFromStreamAsync(stream).Wait();
            }
            Console.WriteLine("upload successful");
            Console.ReadLine();
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
            Console.ReadLine();
        }
}    

并获得如下令牌。

        public static string GetOAuthToken(string activeDirectoryTenantId, string  
           activeDirectoryApplicationSecret, string activeDirectoryApplicationId)
        {
            string resourceId = $"https://storage.azure.com";
            var authority = String.Format("https://login.windows.net/" + activeDirectoryTenantId);

            var credential = new ClientCredential(activeDirectoryApplicationId, activeDirectoryApplicationSecret);

            var context = new AuthenticationContext(authority);
            var result = context.AcquireTokenAsync(resourceId, credential).Result;

            return result.AccessToken;
        }    

谁能建议我可能缺少什么？
P/S 我已经确认我的本地系统与正确的 UTC 时间同步。

我尝试了您问题中的代码，它成功上传了 blob。

注意：

1. 将Storage Blob Data Contributor 角色分配给应用程序

导航到存储帐户 -> 访问控制 (IAM) -> 添加角色分配

1. 按照此step 授予您注册的应用程序对 Azure 存储的权限。
