asp.net-core - ASP.NET Core，Azure 存储控制器

Question

我有一个非常新手的问题。

我正在关注此文档“用于 .NET 的 Azure Blob 存储客户端库 v12” - https://docs.microsoft.com/en-us/azure/storage/blobs/storage-quickstart-blobs-dotnet

当我在我的控制台和 Azure 存储上进行测试时，它可以工作。

但我想知道是否可以使用建议的“主要”方法制作控制器？因为我希望当用户输入从前端更改时启动这些获取和发布到服务器的操作。

这是 Program.cs 内部的 Main 方法基于文档的样子

        static async Task Main()
        {
            Console.WriteLine("Azure Blob storage v12 - .NET quickstart sample\n");

            string connectionString = Environment.GetEnvironmentVariable("My_CONNECTION_STRING");


            BlobServiceClient blobServiceClient = new BlobServiceClient(connectionString);

            string containerName = "quickstartblobs" + Guid.NewGuid().ToString();

            BlobContainerClient containerClient = await blobServiceClient.CreateBlobContainerAsync(containerName);


            string localPath = "./data/";
            string fileName = "quickstart" + Guid.NewGuid().ToString() + ".txt";
            string localFilePath = Path.Combine(localPath, fileName);

            // Write text to the file
            await File.WriteAllTextAsync(localFilePath, "Hello, World!");

            // Get a reference to a blob
            BlobClient blobClient = containerClient.GetBlobClient(fileName);

            Console.WriteLine("Uploading to Blob storage as blob:\n\t {0}\n", blobClient.Uri);

            // Open the file and upload its data
            using FileStream uploadFileStream = File.OpenRead(localFilePath);
            await blobClient.UploadAsync(uploadFileStream, true);
            uploadFileStream.Close();

            Console.WriteLine("Listing blobs...");

            // List all blobs in the container
            await foreach (BlobItem blobItem in containerClient.GetBlobsAsync())
            {
                Console.WriteLine("\t" + blobItem.Name);
            }
            Console.Write("Press any key to begin clean up");
            Console.ReadLine();

            string downloadFilePath = localFilePath.Replace(".txt", "DOWNLOAD.txt");

            Console.WriteLine("\nDownloading blob to\n\t{0}\n", downloadFilePath);

            // Download the blob's contents and save it to a file
            BlobDownloadInfo download = await blobClient.DownloadAsync();

            using (FileStream downloadFileStream = File.OpenWrite(downloadFilePath))
            {
                await download.Content.CopyToAsync(downloadFileStream);
                downloadFileStream.Close();
            }
        }

因此，例如，在我的 HomeController 中，我可以将帖子相关功能用作

            [HttpPost]
            public void Post([FromBody]string value)
            {
                //Create a unique name for the container
                string containerName = "filedata" + Guid.NewGuid().ToString();

                // Create the container and return a container client object
                BlobContainerClient containerClient = await blobServiceClient.CreateBlobContainerAsync(containerName);

                // Create a local file in the ./data/ directory for uploading and downloading
                string localPath = "./data/";
                string fileName = "textfile" + Guid.NewGuid().ToString() + ".txt";
                string localFilePath = Path.Combine(localPath, fileName);

            BlobServiceClient blobServiceClient = new BlobServiceClient(connectionString);

            // Get a reference to a blob
            BlobClient blobClient = containerClient.GetBlobClient(fileName);

            Console.WriteLine("Uploading to Blob storage as blob:\n\t {0}\n", blobClient.Uri);

            // Open the file and upload its data
            using FileStream uploadFileStream = File.OpenRead(localFilePath);
            await blobClient.UploadAsync(uploadFileStream, true);
            uploadFileStream.Close();


            }

或者这是不行的？

感谢您帮助这个超级新手！

因此，例如，在我的 HomeController 中，我可以使用与帖子相关的功能吗？或者这是不行的？

是的，你可以实现它。

您可以使用邮递员在本地发送post请求以进行测试。请记住删除SSL网络服务器设置。

另外，在代码中public void Post 更改public async Task Post并删除：using

 FileStream uploadFileStream = File.OpenRead(localFilePath);
 await blobClient.UploadAsync(uploadFileStream, true);
 uploadFileStream.Close()
