 # 1. 上传文件(默认不覆盖)
 #    将本地的local_file_1.txt上传到bucket的根分区下,并命名为sample_file.txt
 #    默认不覆盖, 如果cos上文件存在,则会返回错误
 request = UploadFileRequest(bucket, u'/sample_file.txt', u'local_file_1.txt')

 print 'upload file ret:', repr(upload_file_ret)

 # 2. 上传文件(覆盖文件)
 # 2.1上传本地文件，将本地的local_file_2.txt上传到bucket的根分区下,覆盖已上传的sample_file.txt
 request = UploadFileRequest(bucket, u'/sample_file.txt', u'local_file_2.txt')

 # 3. 获取文件属性
 request = StatFileRequest(bucket, u'/sample_file.txt')
 stat_file_ret = cos_client.stat_file(request)
 print 'stat file ret:', repr(stat_file_ret)

 # 4. 更新文件属性
 request = UpdateFileRequest(bucket, u'/sample_file.txt')

 request.set_biz_attr(u'this is demo file')        # 设置文件biz_attr属性,不支持中文
 request.set_authority(u'eWRPrivate')              # 设置文件的权限

 update_file_ret = cos_client.update_file(request)
 print 'update file ret:', repr(update_file_ret)

 # 5. 更新后再次获取文件属性
 request = StatFileRequest(bucket, u'/sample_file.txt')
 stat_file_ret = cos_client.stat_file(request)
 print 'stat file ret:', repr(stat_file_ret)

 # 6. 移动文件, 将sample_file.txt移动位sample_file_move.txt
 request = MoveFileRequest(bucket, u'/sample_file.txt', u'/sample_file_move.txt')
 stat_file_ret = cos_client.move_file(request)

 # 7. 删除文件
 request = DelFileRequest(bucket, u'/sample_file_move.txt')
 del_ret = cos_client.del_file(request)
 print 'del file ret:', repr(del_ret)

 # 8. 下载文件
 request = DownloadFileRequest(bucket, u'/sample_file_move.txt')
 del_ret = cos_client.download_file(request)
 print 'del file ret:', repr(del_ret)

 # 9. 下载文件到内存
 request = DownloadObjectRequest(bucket, u'/sample_file_move.txt')
 fp = cos_client.download_object(request)
 fp.read()
