how to set CONTENT_DISPOSITION use ecs-sdk

I wrote some code to  get the filename when  do getObject , but i got some error.

here is my code and some other message

   String oID = UUID.randomUUID().toString(); 
  //上传文件 
   InputStream in = new FileInputStream(tempFile);
   PutObjectRequest ob = new PutObjectRequest(bucketName, oID, in);
   PutObjectResult rlt = s3.putObject(ob);
   System.out.println("上传完成！FileName = "+oID+", File_etag = "+rlt.getETag());
   PresignedUrlRequest urlRequest = new PresignedUrlRequest(Method.GET, bucketName, oID

   , new Date(System.currentTimeMillis()+365*24*3600*1000));
  
   urlRequest.headerOverride(ResponseHeaderOverride.CONTENT_DISPOSITION, "attachment;filename=bame.xlsx;")
   System.out.println(s3.getPresignedUrl(urlRequest).toString());

i run that code and got a url like :

http://172.16.80.175:9020/testbucket/95e5fb06-51b0-406e-8e60-848db7e7dbf4?AWSAccessKeyId=test&Expires=1525685094&Signature=zs9D%2BXxvocnArX62yW%2FplGV7cFw%3D&response-content-disposition=attachment%3Bfilename%3Dbame.xlsx%3B

i copy this url to The Chrome browser ，i got a file named 95e5fb06-51b0-406e-8e60-848db7e7dbf4 but bame.xlsx.

here is the caught

GET /testbucket/95e5fb06-51b0-406e-8e60-848db7e7dbf4?AWSAccessKeyId=test&Expires=1525685094&Signature=zs9D%2BXxvocnArX62yW%2FplGV7cFw%3D&response-content-disposition=attachment%3Bfilename%3Dbame.xlsx%3B HTTP/1.1
