我在尝试使用 swift 放置对象时遇到异常：

org.jclouds.http.HttpResponseException: Incomplete output stream connecting to PUT http://xxx.xx.xx.xxx:8080/v1/AUTH_2c5c2fbbfe22422496d5ebf6861199f2/myContainer1/ HTTP/1.1

        ... 8 more

代码是：

 InputStream is = new ByteArrayInputStream(data.getBytes("UTF-8"));
 Payload payload = new InputStreamPayload(is);
 payload.getContentMetadata().setContentLength((long) 1000);

 ObjectApi objectApi = swiftApi.objectApiInRegionForContainer("RegionOne", CONTAINER_NAME);
 String str = "strName";
 objectApi.put(str, payload);

请任何人指导我如何解决这个问题

【解决方案1】：

您应该提供正确的内容长度，而不是虚假的，例如，

byte[] input = data.getBytes("UTF-8");
InputStream is = new ByteArrayInputStream(input);
Payload payload = new InputStreamPayload(is);
payload.getContentMetadata().setContentLength(input.length);

您可以使用ByteArrayPayload 完全跳过InputStream，它会自动设置长度并提供可重复的有效负载来处理网络超时和其他故障：

byte[] input = data.getBytes("UTF-8");
Payload payload = new ByteArrayPayload(input);
