我正在尝试使用和从android将文件作为blob上传到Azure存储

实际上，我在android中找不到任何使用共享访问签名（SAS）的示例代码。上述移动服务教程适用于.NET应用程序。因此，遵循相同的教程，我正在尝试在android中创建一个用于图像上传的示例应用程序

以下是我的android代码：

 AsyncTask<Void, Void, Void> task = new AsyncTask<Void, Void, Void>(){
        @Override
        protected Void doInBackground(Void... params) {
            try {
                final ImageItem entity = addItemInTable(item);
                Log.d("InsertedItem:", entity.toString());

                StorageCredentials cred = StorageCredentials.tryParseCredentials(entity.getSasQueryString());

                URI imageURI = new URI(entity.getImageUri());

                URI containerUri = new URI("https://" + imageURI.getHost() + "/" + entity.getContainerName());
                Log.d("ContainerURI:", containerUri.toString());

                CloudBlobContainer container = new CloudBlobContainer(containerUri, cred);

                CloudBlockBlob blobFromSASCredential = container.getBlockBlobReference(entity.getResourceName());
                AssetManager assManager = getApplicationContext().getAssets();
                InputStream is = null;
                try {
                    is = assManager.open("image.jpg");

                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
                blobFromSASCredential.upload(is, -1);
              //blobFromSASCredential.uploadText("Sample text");


                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        if (!entity.isComplete()) {
                            mAdapter.add(entity);
                        }
                    }
                });
            } catch (final Exception e) {
                e.printStackTrace();
                createAndShowDialogFromTask(e, "Error");
            }
            return null;
        }
    };

public ImageItem addItemInTable(ImageItem item) throws ExecutionException, InterruptedException {
    item.setContainerName("todoitemimages");
    item.setResourceName(UUID.randomUUID().toString());

    ImageItem entity = mToDoTable.insert(item).get();
    return entity;
}

运行代码时，我遇到以下错误：

tryParseCredentials（）接受连接字符串，因此我认为这不是正确的方法。尝试使用StorageCredentialsSharedAccessSignature构造函数直接创建所需的凭据对象，该构造函数接受SAS令牌

此外，为了上传blob，需要确保上传到的容器存在。如果您确定它是，那么这段代码是好的。否则，容器对象上的create（）或createIfNotExists（）方法就是您所需要的。

是的，您是对的。我只是在晚上想出来的。应直接使用StorageCredentialsSharedAccessSignature构造函数。谢谢你的帮助嘿，普拉卡什！！！你能分享图片上传的代码吗…或者你能给我任何一个开始的链接吗？？？？
