Can't get result by page in sercuritygroups api

[niejn]

def test_security_groups(os_conn):

query = {
"limit": 2
}
objs = os_conn.vpcv1.security_groups(**query)
objs = list(objs)
for obj in objs:
print(obj)

设置limit为2, 但是返回了所有的security groups， limit不起作用，
只有修改sdk中v1/_proxy.py 将self._list(_security_group.SecurityGroup, paginated=True,
**query)改为self._list(_security_group.SecurityGroup, paginated=False,
**query)
sdk 函数如下：
def security_groups(self, **query):
"""Return a generator of security groups

:param dict query: Optional query parameters to be sent to limit
the resources being returned. Valid parameters are:

• limit: The number of records returned on each page.
• marker: The resource ID of pagination query.
• vpc_id: The ID of the VPC this security group is
  associated with.
• enterprise_project_id: The ID of the enterprise project.

:returns: A generator of security group objects
:rtype: :class:~openstack.vpc.v1.security_group.SecurityGroup
"""
return self._list(_security_group.
sdk中是将 paginated=True， 但是效果并没有按照每次返回一个page，而是全部返回了，paginated=False, 反而能够按page返回
