azure-blob-storage - 如何使用 Azure Java azure-storage-blob SDK 设置内容类型

Question

我的代码如下:

    try {
        MultipartFile file = uploadFileInfo.getUploadFile();
        InputStream inputStream = new BufferedInputStream(file.getInputStream());
        BlobProperties props = blockBlobClient.getProperties();
        blockBlobClient.upload(inputStream, file.getBytes().length);
    } catch (IOException e) {
        log.error("Unable to upload blob!", e);
        return baseResp;
    }

但是文件 contentType 是 application/octet-stream，我需要将其设置为“image/jpg”。如何使用 Java SDK 执行此操作？

要上传 Blob 并设置其内容类型，请使用以下方法:BlockBlobClient.uploadWithResponse 。这是示例代码(取自同一链接):

BlobHttpHeaders headers = new BlobHttpHeaders()
     .setContentType("image/jpg");
 
 Map<String, String> metadata = Collections.singletonMap("metadata", "value");
 
 byte[] md5 = MessageDigest.getInstance("MD5").digest("data".getBytes(StandardCharsets.UTF_8));
 
 BlobRequestConditions requestConditions = new BlobRequestConditions();
 Context context = new Context("key", "value");
 client.uploadWithResponse(data, length, headers, metadata, AccessTier.HOT, md5,
         requestConditions, timeout, context);
