假设您通过创建CloudBlockBlob的示例，使用.Net存储客户端库将blob上载到blob存储中，则可以通过阅读blob的Uri属性来获取blob的URL。

static void BlobUrl()
{
    var account = new CloudStorageAccount(new StorageCredentials(accountName, accountKey), true);
    var cloudBlobClient = account.CreateCloudBlobClient();
    var container = cloudBlobClient.GetContainerReference("container-name");
    var blob = container.GetBlockBlobReference("image.png");
    blob.UploadFromFile("File Path ....");//Upload file....

    var blobUrl = blob.Uri.AbsoluteUri;
}

对于python用户，可以使用blob_client.url
遗憾的是，https://learn.microsoft.com中未记录此操作

from azure.storage.blob import BlobServiceClient
# get your connection_string - look at docs
blob_service_client = BlobServiceClient.from_connection_string(connection_string)
container_client = blob_service_client.get_container_client(storage_container_name)
You can call blob_client.url
blob_client = container_client.get_blob_client("myblockblob")
with open("pleasedelete.txt", "rb") as data:
    blob_client.upload_blob(data, blob_type="BlockBlob")
print(blob_client.url)

将返回https://pleasedeleteblob.blob.core.windows.net/pleasedelete-blobcontainer/myblockblob

当你使用更新的 “Azure存储Blob” 包时，请使用以下代码。

BlobClient blobClient = containerClient.GetBlobClient("lg.jpg");

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

using FileStream uploadFileStream = File.OpenRead(fileName);

if (uploadFileStream != null) 
    await blobClient.UploadAsync(uploadFileStream, true);

var absoluteUrl= blobClient.Uri.AbsoluteUri;

截至2020年的完整工作Javascript解决方案：

const { BlobServiceClient } = require('@azure/storage-blob')

const AZURE_STORAGE_CONNECTION_STRING = '<connection string>'

async function main() {
  // Create the BlobServiceClient object which will be used to create a container client
  const blobServiceClient = BlobServiceClient.fromConnectionString(AZURE_STORAGE_CONNECTION_STRING);

  // Make sure your container was created
  const containerName = 'my-container'

  // Get a reference to the container
  const containerClient = blobServiceClient.getContainerClient(containerName);
  // Create a unique name for the blob
  const blobName = 'quickstart.txt';

  // Get a block blob client
  const blockBlobClient = containerClient.getBlockBlobClient(blobName);

  console.log('\nUploading to Azure storage as blob:\n\t', blobName);

  // Upload data to the blob
  const data = 'Hello, World!';
  await blockBlobClient.upload(data, data.length);
  
  console.log("Blob was uploaded successfully. requestId: ");
  console.log("Blob URL: ", blockBlobClient.url)
}

main().then(() => console.log('Done')).catch((ex) => console.log(ex.message));

这是V12的方法。我不能保证我的变量名是准确的，但是代码可以工作。

protected BlobContainerClient AzureBlobContainer
{
  get
  {
    if (!isConfigurationLoaded) { throw new Exception("AzureCloud currently has no configuration loaded"); }
    if (_azureBlobContainer == null)
    {
      if (!string.IsNullOrEmpty(_configuration.StorageEndpointConnection))
      {

        BlobServiceClient blobClient = new BlobServiceClient(_configuration.StorageEndpointConnection);
        BlobContainerClient container = blobClient.GetBlobContainerClient(_configuration.StorageContainer);
        container.CreateIfNotExists();
        _azureBlobContainer = container;
      }
    }
    return _azureBlobContainer;
  }
}

public bool UploadFileToCloudStorage(string fileName, Stream fileStream)
{
  BlobClient cloudFile = AzureBlobContainer.GetBlobClient(fileName);
  cloudFile.DeleteIfExists();
  fileStream.Position = 0;
  cloudFile.Upload(fileStream);
  return true;
}

public BlobClient UploadFileToCloudStorageWithResults(string fileName, Stream fileStream)
{
  BlobClient cloudFile = AzureBlobContainer.GetBlobClient(fileName);
  cloudFile.DeleteIfExists();
  fileStream.Position = 0;
  cloudFile.Upload(fileStream);

  return cloudFile;
}

public Stream DownloadFileStreamFromCloudStorage(string fileName)
{
  BlobClient cloudFile = AzureBlobContainer.GetBlobClient(fileName);
  Stream fileStream = new MemoryStream();
  cloudFile.DownloadTo(fileStream);
  return fileStream;
}

嘿，我很抱歉，我不知道我是如何张贴同样的评论再次在答案。请找到我的正确答案下面详细解释如何从blob存储blob工作的网址。
//在web.config文件中添加连接字符串，以便在需要时轻松地在多个位置获取。

<connectionStrings>

<add name="BlobStorageConnection" connectionString="DefaultEndpointsProtocol=https;AccountName=accName;AccountKey=xxxxxxxxxxxxxxxxxx YOU WILL FIND THIS in your AZURE ACCOUNT xxxxxxxxxx==;EndpointSuffix=core.windows.net"/>

这是您可以从web.config文件中获取的字符串。

string BlobConnectionString = ConfigurationManager.ConnectionStrings["BlobStorageConnection"].ConnectionString;
     public string GetFileURL()
        {
        //This will create the storage account to get the details of account.
        CloudStorageAccount cloudStorageAccount = CloudStorageAccount.Parse(BlobConnectionString);

        //create client
        CloudBlobClient cloudBlobClient = cloudStorageAccount.CreateCloudBlobClient();

        //Get a container
        CloudBlobContainer cloudBlobContainer = cloudBlobClient.GetContainerReference("ContainerName");

        //From here we will get the URL of file available in Blob Storage.
        var blob1 = cloudBlobContainer.GetBlockBlobReference(imageName);
        string FileURL=blob1.Uri.AbsoluteUri;
        return FileURL;

    }

像这样，如果你有文件（或图像）名称，你可以得到文件的URL。
