Can'；t从Junos输出使用（-）访问JSON元素-Ansible 2.8

我需要帮助才能从junos_命令输出中访问包含（-）的JSON元素。我似乎不知道如何通过bgp信息

我使用的是junos_命令模块。我在使用juniper_junos_命令模块时也遇到了同样的问题

我使用的是Ansible 2.8版

从剧本：

    - name: Show BGP neighbor JSON output
      junos_command:  
        commands:
          - show bgp neighbor 174.68.232.1
        display: json  
      register: configs

    - name: Debug output
      debug:
        var: configs.stdout[0]

    - name: Debug output
      debug:
        var: configs.stdout[0]['bgp-information']['bgp-peer']

调试输出（部分）：

---

您可以看到

bgp信息

是一个列表变量（下一行以破折号开始）。因此，您的最后一项任务应该是：

- name: Debug output
  debug:
    var: configs.stdout[0]['bgp-information'][0]['bgp-peer']

希望能有帮助

更新

我获取了您提供的输出，并在变量中定义了它，下面是用于测试答案的剧本：

---
- hosts: localhost
  gather_facts: false
  vars:
    configs_stdout:
    - bgp-information:
      - attributes:
          xmlns: http://xml.juniper.net/junos/16.1R4/junos-routing
        bgp-peer:
        - active-holdtime:
          - data: '90'
          attributes:
            junos:style: detail
          bgp-bfd:
          - bfd-configuration-state:
            - data: disabled
            bfd-operational-state:
            - data: down
          bgp-option-information:
          - address-families:
            - data: inet-unicast inet-multicast inet-vpn-unicast inet-vpn-multicast inet-labeled-unicast inet6-labeled-unicast inet-mvpn
            attributes:
              xmlns: http://xml.juniper.net/junos/16.1R4/junos-routing
            authentication-configured:
            - data:
              - null
            bgp-options:
            - data: Preference LocalAddress AdvertiseInactive AuthKey LogUpDown AddressFamily Multipath Rib-group Refresh
            bgp-options-extended:
            - {}
            bgp-options2:
            - {}
            export-policy:
            - data: iBGP-POLICY
            holdtime:
            - data: '90'
            import-policy:
            - data: iBGP-IN
            local-address:
            - data: 174.68.232.31

  tasks:
  - name: Debug output
    debug:
      var: configs_stdout

  - name: Debug output
    debug:
      var: configs_stdout[0]['bgp-information'][0]['bgp-peer']

---

如果运行PB，您将验证

var:configs.stdout[0]['bgp-information'][0]['bgp-peer']

是否有效。

我使用regex\u replace找到了一个解决方案

    - name: Show BGP neighbor JSON output
      juniper_junos_command:  
        provider: "{{ credentials }}"
        commands:

        display: json  
      register: configs

    - name: set fact
      set_fact:
        bgp_neighbor: "{{ configs.parsed_output | regex_replace('-', '_') }}"

您好，我刚刚尝试过，但仍在获取配置。标准输出[0]['bgp-information'][0]['bgp-peer']：未定义变量！–还有其他建议吗？请看更新后的答案，我添加了一个PB来测试结果。假设变量是您在问题中粘贴的，那么它应该可以工作..谢谢您的帮助。通过使用regex_replace，我能够从输出中获得所需的内容。
