java - 要上传的特定文件的 Azure SAS 令牌？具有读取和到期时间（JAVA）

Question

我有BlobServiceAsyncClient

使用TenantID, clientID, ClientSecret,ContainerName来创建blobContainerAsyncClient.

上传文件为

blobContainerAsyncClient.getBlobAsyncClient(fileName).upload(.........);

Answer 1

您可以使用以下代码

创建具有只读权限且仅在接下来的 10 分钟内可用的共享访问签名。

public string CreateSAS(string blobName)

{
    var container = blobClient.GetContainerReference(ContainerName);

    // Create the container if it doesn't already exist
    container.CreateIfNotExists();

    var blob = container.GetBlockBlobReference(blobName);

    var sas = blob.GetSharedAccessSignature(new SharedAccessBlobPolicy()
    {
        Permissions = SharedAccessBlobPermissions.READ,
        SharedAccessExpiryTime = DateTime.UtcNow.AddMinutes(10),
    });

    return sas;
}
