Ansible：在字典对象中处理正斜杠失败。 抬头

Question

Code:

- name: Testing PyATS

  tasks:

  - name: Read in parse_genie role
    include_role:
      name: clay584.parse_genie

  - name: show interfaces
    ios_command:
      commands:
        - show interfaces
    register: interfaces

  - name: Set Fact Genie Filter
    set_fact: 
      pyats_interfaces: "{{ interfaces['stdout'][0] | parse_genie(command='show interfaces', os='iosxe') }}"

  - name: Debug
    debug:
      var: pyats_interfaces.GigabitEthernet0/0

Expect:

 "ansible_facts": {
        "pyats_interfaces": {
            "GigabitEthernet0/0": {
                "arp_timeout": "04:00:00",
                "arp_type": "arpa",
                "auto_negotiate": true,
                "bandwidth": 1000000,
                "counters": {
                    "in_broadcast_pkts": 0,
                    "in_crc_errors": 0,
                    "in_errors": 0,
                    "in_frame": 0,
                    "in_giants": 0, etc.

Getting:

"pyats_interfaces.GigabitEthernet0/0": "VARIABLE IS NOT DEFINED:: 'dict object' has no attribute 'GigabitEthernet0'"

It appears the / is being treated as an escape character and causing the variable to show up as undefined when searching the dict. for G0/0.

Answer 1

You have 2 equivalent syntax to address vars inside a dictionaries in ansible:

• The dot notation:

some.var.to.address

• The bracket notation:

some['var']['to']['address']

Both notations can be mixed in the way you want eg some['var']['to'].address

Although they are equivalent, some cases force you to use the bracket notation.

• when the name of the field comes from a variable eg my_var[item]
• when the name of the field contains special characters eg my_var['field with spaces']

You are in this latest case. So replacing your debug line with the following should fix your problem:

- name: Debug
  debug:
    var: pyats_interfaces['GigabitEthernet0/0']
