Java 我们如何在容器下创建子文件夹我的问题与此不同

我想将特定映像或配置文件存储在如下结构中：

/test/images/abc.png
/test/images1/abc.png

问题：我们如何在容器下创建子文件夹。在我的用例测试中，将有一个容器，图像将保存在文件夹中，图像和图像1将在存储abc.png文件时创建

在AWS中，它会自动创建这样的路径，我们可以直接存储

下面是我试图执行的代码。

CloudStorageAccount account = CloudStorageAccount.parse(storageConnectionString);
CloudBlobClient client = account.createCloudBlobClient();
CloudBlobContainer container = client.getContainerReference("test");
String key="images1/746ca358-2c6d-41f1-943e-a6a5ae287826.png";
CloudBlockBlob blob = container.getBlockBlobReference(key);

File sourceFile = new File("/Users/saurabhmishra/Desktop/error.png");
FileInputStream inputStream = new FileInputStream(sourceFile);
blob.upload(inputStream,100);

我得到以下错误。

CloudStorageAccount account = CloudStorageAccount.parse(storageConnectionString);
CloudBlobClient client = account.createCloudBlobClient();
CloudBlobContainer container = client.getContainerReference("test");
String key="images1/746ca358-2c6d-41f1-943e-a6a5ae287826.png";
CloudBlockBlob blob = container.getBlockBlobReference(key);

File sourceFile = new File("/Users/saurabhmishra/Desktop/error.png");
FileInputStream inputStream = new FileInputStream(sourceFile);
blob.upload(inputStream,100);

以下是一个示例：

    public static void main(String[] args) throws Exception {
        String connectionString = "DefaultEndpointsProtocol=https;AccountName=storagetest789;AccountKey=G3*****************************w==;EndpointSuffix=core.windows.net";
        StorageCredentials credentials = StorageCredentials.tryParseCredentials(connectionString);

        CloudStorageAccount storageAccount = new CloudStorageAccount(credentials, true);
        CloudBlobClient blobClient = storageAccount.createCloudBlobClient();
        CloudBlobContainer blobContainer = blobClient.getContainerReference("pub");
        blobContainer.createIfNotExists();

        CloudBlobDirectory subDirectory = blobContainer.getDirectoryReference("subDirectory1/subdirectory2/");
        CloudBlockBlob blockBlob = subDirectory.getBlockBlobReference("test.txt");
        blockBlob.uploadFromFile("D:\\User\\Desktop\\test.txt");

    }

基本上，您只需要使用

blobContainer.getDirectoryReference（“subDirectory1/subdirectory2/”）获取目录引用，则可以从中获取块blob引用

我觉得你的代码还可以。您是否在blob.upload（inputStream，100）上得到错误信息行？是的，我也知道line@SaurabhMishra你能检查一下我的答案看是否有用吗？谢谢，杰克，是的，这很有用，我已经做到了
