我有一个任务，该任务将从开关返回的输出分配给变量，然后下一个任务通过jinja2模板运行输出：
- name: CHECKING SPANNING-TREE STATE
nxos_command:
commands:
- show spanning-tree
provider: "{{ nxos_provider }}"
register: stp
- name: RUN OUTPUT THROUGH TEMPLATE THEN WRITE OUTPUT TO FILE
template:
src: /sandbox/git/net/ansible/roles/template/templates/stp.j2
在Jinja2模板中，我可以使用下面的逻辑轻松地遍历“ TABLE_tree.ROW_tree”，但是当我尝试遍历“ TABLE_port.ROW_port”时，在Ansible中会出现“ undefinedvariable”错误。只是不确定如何为每个“ TABLE_tree.ROW_tree”遍历嵌套字典（TABLE_port.ROW_port）。任何帮助将不胜感激。
工作逻辑代码段：
{% for tree in stp.stdout_lines[0].TABLE_tree.ROW_tree %}
VLAN{{ tree.tree_id }}:
Root Bridge Priority: {{ tree.tree_designated_root_priority }}
逻辑中断：
{% for interface in stp.stdout_lines[0].TABLE_tree.ROW_tree.TABLE_port.ROW_port. %}
INTERFACES STATES:
Interface {{ interface.if_index }}
Role: {{ interface.role }}
State: {{ interface.state }}
------------------------------------------------------
{% endfor %}
