Apache-ranger python库JSONDecoder错误

Question

因此，我试图使用ranger客户端创建一个策略，这是我的代码(为安全目的编辑机密信息)。

from apache_ranger.model.ranger_service import *
from apache_ranger.client.ranger_client import *
from apache_ranger.model.ranger_policy  import *


ranger_url  = 'http://************.com:***'
ranger_auth = ('**********', '**********')

ranger = RangerClient(ranger_url, ranger_auth)

policy           = RangerPolicy()
policy.service   = 'starburst-enterprise'
policy.name      = 'test_policy'
policy.resources = { 'database': RangerPolicyResource({ 'values': ['hive'] }),
                     'table':    RangerPolicyResource({ 'values': ['uber_rides'] }),
                     'column':   RangerPolicyResource({ 'values': ['*'] }) }

allowItem1          = RangerPolicyItem()
allowItem1.groups   = [ 'Data Product Owner' ]
allowItem1.accesses = [ RangerPolicyItemAccess({ 'type': 'select' }) ]

denyItem1          = RangerPolicyItem()
denyItem1.groups    = [ 'Data Product Owner' ]
denyItem1.accesses = [ RangerPolicyItemAccess({ 'type': 'drop' }) ]

policy.policyItems     = [ allowItem1 ]
policy.denyPolicyItems = [ denyItem1 ]

print('Creating policy: name=' + policy.name)

created_policy = ranger.create_policy(policy)

print('    created policy: name=' + created_policy.name + ', id=' + str(created_policy.id))

但是我收到了这个错误，当我尝试调试它时，我发现，它之所以会出现异常，是因为ranger_clien.py中的ranger_clien.py方法返回了一个响应()，该响应没有被任何if或elifs块处理，因此它进入了RaiseServiceException()块，当我深入挖掘时，我在函数中发现了一些给JSONDecoder错误的注释，它说只有当JSON输入无效或者没有安装simplejson时，才会引发异常。

我只需要在ranger_url中传递'https‘而不是'http’就知道了
