如何使用 json_modify.py 更改 JSON 键名称？
我有以下数组，我想将 public_ip_address 更改为 public_ip_address_name。
"ip_configurations": [
{
"application_gateway_backend_address_pools": null,
"application_security_groups": null,
"load_balancer_backend_address_pools": null,
"name": "Ubuntu915",
"primary": true,
"private_ip_address": "10.0.0.5",
"private_ip_allocation_method": "Dynamic",
"public_ip_address": "/subscriptions/123456/resourceGroups/cloud-shell-storage-centralindia/providers/Microsoft.Network/publicIPAddresses/Ubuntu-915-test",
"public_ip_allocation_method": "Dynamic"
}
],
这是我如何使用 json_modify 的示例，但我不确定如何更改 key 。
- json_modify:
data: "{{ azure_network_interface_info }}"
pointer: "/networkinterfaces/0/ip_configurations/0"
action: update
update: { "public_ip_address": "testing" }
register: azure_network_interface_info_modified
以下是 azure_network_interface_info 的事实:

最佳答案
好的，我找到了一个解决方案，就是修改库文件夹中的模块:
我添加了一个新功能renamekey，旧 key 的内容会自动添加到新 key
from ansible.module_utils.basic import AnsibleModule
import json
try:
import jsonpointer
except ImportError:
jsonpointer = None
def main():
module = AnsibleModule(
argument_spec=dict(
data=dict(required=True, type='dict'),
pointer=dict(required=True),
action=dict(required=True,
choices=['append', 'extend', 'update', 'renamekey']),
update=dict(type='dict'),
extend=dict(type='list'),
append=dict(),
renamekey=dict(type='list'),
),
supports_check_mode=True,
)
if jsonpointer is None:
module.fail_json(msg='jsonpointer module is not available')
action = module.params['action']
data = module.params['data']
pointer = module.params['pointer']
if isinstance(data, str):
data = json.loads(str)
try:
res = jsonpointer.resolve_pointer(data, pointer)
except jsonpointer.JsonPointerException as err:
module.fail_json(msg=str(err))
if action == 'append':
res.append(module.params['append'])
if action == 'extend':
res.extend(module.params['extend'])
elif action == 'update':
res.update(module.params['update'])
elif action == 'renamekey':
oldkey = module.params['renamekey'][0]
newkey = module.params['renamekey'][1]
value = res[oldkey] #get the value of oldkey
res.pop(oldkey) #delete the oldkey
res.update({module.params['renamekey'][1]: value}) #add newkey with value saved
module.exit_json(changed=True,
result=data)
if __name__ == '__main__':
main()
要测试的剧本:
- json_modify:
data: "{{ azure_network_interface_info }}"
pointer: "/networkinterfaces/0/ip_configurations/0"
action: renamekey
renamekey: ["public_ip_address", "public_ip_address_name"] #[oldkey, newkey]
register: result
结果:
"ip_configurations": [
{
"application_gateway_backend_address_pools": null,
"application_security_groups": null,
"load_balancer_backend_address_pools": null,
"name": "Ubuntu915",
"primary": true,
"private_ip_address": "10.0.0.5",
"private_ip_allocation_method": "Dynamic",
"public_ip_address_name": "/subscriptions/123456/resourceGroups/test-rg/providers/Microsoft.Network/publicIPAddresses/Ubuntu915-publicIp",
"public_ip_allocation_method": null
}
