java - 无法将文件上传到 SAS URI

Question

这里我使用 Microsoft Storage Library，但我无法将文件上传到 Azure 存储

代码:

 public class UploadFile {

public static void uploadFile(String sasURL,String filePath,String submissionGuid) throws MalformedURLException, URISyntaxException
{
    URI sasUrl = new URI(sasURL);

    try
    {
        CloudBlobContainer container = new CloudBlobContainer(sasUrl);
        CloudBlockBlob blob = container.getBlockBlobReference(sasUrl.getPath());
        File source = new File(filePath);
        blob.upload(new FileInputStream(source), source.length());
    }
    catch (Exception e)
    {
        // Output the stack trace.
        e.printStackTrace();
    }


}
}

生成的 Sas Uri 是:

我收到错误消息:

还有授权错误，即使传递的 sasuri 中包含所有必需的参数:

我想我不明白我应该传递 Blob-container-name 的部分，因为我什至尝试传递 org66 但它对我不起作用。

我也对我的容器名称等部分感到困惑。

SAS 中的每个“&sr=b”，它是 Blob 级别 SAS，而不是容器级别 SAS，您应该直接使用它来构造 CloudBlockBlob 对象，而不是通过 CloudBlobContainer:

CloudBlockBlob blob = new CloudBlockBlob(new URI(sasURL));
File source = new File(filePath);
blob.upload(new FileInputStream(source), source.length());

您可以在 official documentation 中找到有关如何正确使用容器 SAS 和 Blob SAS 的详细信息。虽然它基于 C#，但代码大体相似。
