c# - CloudBlockBlob 的 URI 在 C# 中给出特殊字符

Question

我有与 Azure Blob 交互的简单代码，如下所示。
我想获取上传文件的 URL。
假设如果在我的 blob 存储中，我有一个容器，其中有多个文件夹，我需要获取文件的路径。因此，为了获取该路径，我尝试使用 blockBlob.Uri 参数。

using Microsoft.WindowsAzure.Storage;
using Microsoft.WindowsAzure.Storage.Blob;
using System;
using System.IO;
namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {         
            string   storageAccConnString = "Connection string";
            CloudStorageAccount storageAccount = "Account Name";
            CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();
            string folderPath    "Folder1" + Path.DirectorySeparatorChar + "Folder2" + Path.DirectorySeparatorChar + "Folder3";
            CloudBlobContainer container = blobClient.GetContainerReference(folderPath);
            CloudBlockBlob blockBlob = container.GetBlockBlobReference("Local system filePath which needs to be uploaded to Blob");
            Console.WriteLine("URI : " + blockBlob.Uri);
            Console.WriteLine("URI : " + blockBlob.Uri.ToString());
            Console.WriteLine("URI : " + blockBlob.Uri.OriginalString);
            Console.ReadLine();  
            // I didnt write the upload code as my question was regarding URI
        }
    }
}

我收到了对此的响应，但我收到的不是“/”或“\”等文件夹分隔符，而是 %5C .

URI : https://storageaccountname.blob.core.windows.net/Folder1%5CFolder2%5Folder3/Test.zip

我该如何纠正这个问题。任何帮助都会有用。谢谢。

您的代码存在一些问题:

• 首先，Blob 存储有两级层次结构:容器和 Blob。您为容器创建引用的方式不正确。由于您的容器名称包含 URL 保留字符 (\)，因此它的 URL 编码为 %5C。
• 接下来，如果要上传容器内虚拟文件夹内的文件，则需要将虚拟文件夹的路径附加到 blob 的名称中。例如，假设您有一个名为 files 的 Blob 容器，并且您想要上传名为 myfile.txt 的文件，但将其放入 Folder1/Folder2/Folder3 虚拟文件夹，您可以这样做:

static void Main(string[] args)
{         
    string   storageAccConnString = "Connection string";
    CloudStorageAccount storageAccount = "Account Name";
    CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();       
    CloudBlobContainer container = blobClient.GetContainerReference('files');
    var blobName = "Folder1/Folder2/Folder3" + "myfile.txt";
    CloudBlockBlob blockBlob = container.GetBlockBlobReference(blobName);
    Console.WriteLine("URI : " + blockBlob.Uri);
    Console.WriteLine("URI : " + blockBlob.Uri.ToString());
    Console.WriteLine("URI : " + blockBlob.Uri.OriginalString);
    Console.ReadLine();  
    // I didnt write the upload code as my question was regarding URI
}
