openstack4j是否支持上传图片时设置header？

Question

我有一些关于OpenStack swift对象存储的问题。我想为对象设置一个过期时间。我使用openstack4j。我的上传对象代码

public void add(String objectName, InputStream imageStream) {
    OSClientV3 clientV3 = OSFactory.clientFromToken(swiftOS.getToken());
    Map<String, String> metaData = new HashMap<>();
    metaData.put("X-Delete-After", "120");
    ObjectPutOptions objectPutOptions = ObjectPutOptions.create();
    objectPutOptions.metadata(metaData);
    clientV3.objectStorage().objects().put(container, objectName,
            Payloads.create(imageStream), objectPutOptions);
}

但它不起作用。然后我尝试使用swift命令行。

swift stat test test-19b8e4d4-1085-490d-b866-97f0ada0d46c

我得到的是

             Container: test

当我通过以下方式上传对象时

swift upload test test.jpg -H "X-Delete-After: 120"

然后

swift stat test test.jpg

就像openstack document说的那样。

The X-Delete-After header takes an integer number of seconds. 
The proxy server that receives the request will convert this 
header into an X-Delete-At header using its current time plus 
the value given.

但是为什么openstack4j不能工作呢？

Answer 1

看起来我们可以用

objectPutOptions.getOptions().put("X-Delete-After", "120");

当getOptions调用返回时，头部映射成垂直向上。

Answer 2

您应该使用header而不是metadata：

objectPutOptions.header("X-Delete-After", "120");
