Question

这里我使用的是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();
    }


}
}

Sas Uri Generated是：

我收到错误消息：

和授权错误，即使传递的sasuri包含所有必需的参数：

我想我不理解我应该传递Blob-container-name的部分，因为我甚至尝试传递org66但是它对我没用。

我也很困惑，因为我的容器名称等等。

Answer 1

在SAS中，每个“＆amp; sr = b”，它是一个blob级SAS而不是容器级SAS，你应该直接用它来构建你的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());

您可以找到有关如何正确使用容器SAS＆amp;这个official documentation中的blob SAS。虽然它基于C＃，但代码通常类似。

Answer 2

首先，您的SAS已于两天前过期（se = 2016-07-13）。

其次，从CloudBlobContainer docs，您使用的构造函数应该获取容器URI ：

指定容器的绝对URI的Uri对象。

如果您的容器是公共的，则不需要SAS，否则 - 使用容器的SAS URI ，因为也可以为特定的blob创建SAS。

无法将文件上传到SAS URI
