调用ListAccessKeys出错了， 提示没有权限。

下面的代码出了这个错误，请问我的帐号要怎么才能有调用ListAccessKeys的权限。
谢谢

错误信息是：

"You are not authorized to do this action. Resource: acs:ram:*:1474796784250055:user/THIS-IS-MY-ACCOUNT Action: ram:ListAccessKeys"

代码如下

from aliyunsdkasapi.ASClient import ASClient
from aliyunsdkasapi.AsapiRequest import AsapiRequest

client = ASClient("sdfgasdfq4rerwer", "asdfsfhqwerahutkyifasdfadf", "cn-hk-abcdefg",timeout=10000,
            cert_file=None,
            verify=False)

client.setSdkSource("asapi-260@asapi-inc.com")

endpoint = "https://public.asapi.cn-hk-abcdefg.ali.cloud.cn.abcdefg/asapi/v3"

request = AsapiRequest("Ram", "2015-05-01", "ListAccessKeys", endpoint)

request.set_method("POST")

response = client.do_request(request)

print(str(response, encoding='utf-8'))
