Cấu hình Azure Storage

Step 1: tạo Azure Storage Account

Step 2: tạo Container

Step 3: download tool Azure Storage Explorer dùng để duyệt file và thư mục tương tự như Explorer của Window

Download tại đây: https://azure.microsoft.com/en-us/features/storage-explorer/

Code chức năng Upload và Download BlobFile trên Azure Storage Container

Step 1: sử dụng NuGet Package manager để cài đặt thư viện

  • Tool -> Nuget Package Manager -> Manage Nuget packages for Solution
  • Chọn tab Browse -> gõ từ khóa WindowsAzure.Storage
  • Chọn Install để cài đặt thư viện

Step 2: lấy chuỗi kết nối (connection string) đến Azure Storage

  • Truy cập portal.azure.com
  • Login tài khoản
  • Chọn Storage Accounts -> Access Key
  • Copy chuỗi Connection String.
    • Ví dụ: `DefaultEndpointsProtocol=https;AccountName=azurestudentsdiag959;AccountKey=yYLvvu+cHBGK/sBLIvbYkVzE/VBS+z5Tw4K5komw2ybyvFYIV7ilKtYZnfa7rYQwUvTSrmFniX9QNrLyq9y3sQ==;EndpointSuffix=core.windows.net`

Step 3: viết hàm Upload file lên Azure Storage

3.1. Tạo biến lưu trữ kết nối (connection string) đến Azure Storage

public string StorageConnectionString = "DefaultEndpointsProtocol=https;AccountName=azurestudentsdiag959;AccountKey=yYLvvu+cHBGK/sBLIvbYkVzE/VBS+z5Tw4K5komw2ybyvFYIV7ilKtYZnfa7rYQwUvTSrmFniX9QNrLyq9y3sQ==;EndpointSuffix=core.windows.net";

3.2. Bổ sung code upload file cho các action Create, Edit

// Update file lên thư mục Storage Azure
// Create Reference to Azure Storage Account
String strorageconn = this.StorageConnectionString;
CloudStorageAccount storageacc = CloudStorageAccount.Parse(strorageconn);

//Create Reference to Azure Blob
CloudBlobClient blobClient = storageacc.CreateCloudBlobClient();

//The next 2 lines create if not exists a container named "democontainer"
CloudBlobContainer container = blobClient.GetContainerReference("democontainer");
container.CreateIfNotExists();

//The next 7 lines upload the file test.txt with the name DemoBlob on the container "democontainer"
CloudBlockBlob blockBlob = container.GetBlockBlobReference(_FileName);
blockBlob.UploadFromStream(image.InputStream);

Step 4: viết hàm lấy Link hiển thị Hình ảnh từ Azure Storage

/// <summary>
/// Hàm lấy đường dẫn URL từ Storage Azure
/// </summary>
/// <returns>Image URL</returns>
public string GetImageUrlFromAzureStore()
{
    string blobUrl = "";

    // Update file lên thư mục Storage Azure
    // Create Reference to Azure Storage Account
    String strorageconn = this.StorageConnectionString;
    CloudStorageAccount storageacc = CloudStorageAccount.Parse(strorageconn);

    //Create Reference to Azure Blob
    CloudBlobClient blobClient = storageacc.CreateCloudBlobClient();

    //The next 2 lines create if not exists a container named "democontainer"
    CloudBlobContainer container = blobClient.GetContainerReference("democontainer");

    //The next 7 lines upload the file test.txt with the name DemoBlob on the container "democontainer"
    CloudBlockBlob blockBlob = container.GetBlockBlobReference(this.image); // hoahong.jpg
    blobUrl = blockBlob.Uri.AbsoluteUri; //https://azure.storage.com/kellyfire/democontainer/hoahong.jpg

    return blobUrl;
}
