ansible - 如果 json 键名称中包含破折号，则带有 json 循环的 Ansible playbook 不起作用

Question

如果 json 键名称中包含破折号，Ansible playbook 将无法工作，如果没有破折号，则可以正常工作。

我尝试使用 from_json 和 json_query，但遇到了同样的问题

这是我必须解析的输出:

ok: [2.2.2.2] => {
    "bgp": {
        "response": {
            "@status": "success",
            "result": {
                "entry": [
                    {
                        "@peer": "V4",
                        "@vr": "VR",

                        "aggregate-confed-as": "yes",
                        "config": {
                            "remove-private-as": "yes"
                        },

                        "keepalive-config": "30",
                        "last-error": null,
                        "last-update-age": "634",
                        "local-address": "3.3.3.3",
                        "msg-total-in": "0",
                        "msg-total-out": "0",
                        "msg-update-in": "0",
                        "msg-update-out": "0",
                        "multi-hop-ttl": "1",
                        "nexthop-peer": "no",
                        "nexthop-self": "no",
                        "nexthop-thirdparty": "yes",
                        "open-delay": "0",
                        "passive": "no",
                        "password-set": "no",
                        "peer-address": "2.2.2.2",
                        "peer-capability": null,
                        "peer-group": "PEER_A",
                        "peer-router-id": "0.0.0.0",
                        "peering-type": "Unspecified",
                        "prefix-counter": null,
                        "prefix-limit": "5000",
                        "reflector-client": "not-client",
                        "remote-as": "65000",
                        "same-confederation": "no",
                        "status": "Connect",
                        "status-duration": "0",
                        "status-flap-counts": "49"
                    }
                ]
            }
        }
    }
}

这是我当前的代码(当我添加“对等地址”时出现问题):

 - debug:
     msg:
       peer-address: "{{ item.peer-address }}"
       status: "{{ item.status }}"
   loop: "{{ (result_3.stdout|from_json).response.result.entry }}"

这是我收到的错误:

{"msg": "The task includes an option with an undefined variable. The error was: 'dict object' has no attribute 'peer'\n\nThe error appears to have been in '/etc/ansible/Playbook-v2.yml': line 49, column 6, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n - debug:\n ^ here\n"}

我只想获取我正在解析的两个键和值:

"peer-address": "2.2.2.2"
"status": "Connect"

这是你的问题:

peer-address: "{{ item.peer-address }}"

名称 peer-address 不是有效的标识符(在 Jinja 语法中，与大多数语言一样，变量名称不能包含 -)。您可以使用替代语法来引用键:

peer-address: "{{ item['peer-address'] }}"
