我正在遍历一些python命令，并将其结果注册到名为 scriptstatus 的变量中。 scriptstatus的示例输出为：
{
"scriptstatus": {
"msg": "All items completed",
"changed": true,
"results": [
{
"_ansible_parsed": true,
"stderr_lines": [
"WARNING:root:No device with given manufacturer and type found! Hint: Do you used HEX-numbers?"
],
"_ansible_item_result": true,
"end": "2018-08-28 12:02:26.992264",
"_ansible_no_log": false,
"stdout": "",
"cmd": [
"python3",
"/home/pi/set_local_parameter.py",
"--api",
"openhab",
"--parameter_num",
"parameter_nums",
"--parameter_val",
"parameter_vals",
"--word_size",
"word_sizes",
"--man_id",
"010F",
"--references",
"0801:1001",
"0801:2001",
"0801:3001",
"0801:4001",
"8800:3001"
],
"rc": 0,
"start": "2018-08-28 12:02:26.252247",
"failed": false,
"delta": "0:00:00.740017",
"item": [
"parameter_nums",
"parameter_vals",
"word_sizes"
],
"changed": true,
"invocation": {
"module_args": {
"creates": null,
"executable": null,
"_uses_shell": false,
"_raw_params": "python3 /home/pi/set_local_parameter.py --api openhab --parameter_num parameter_nums --parameter_val parameter_vals --word_size word_sizes --man_id 010F --references 0801:1001 0801:2001 0801:3001 0801:4001 8800:3001",
"removes": null,
"argv": null,
"warn": true,
"chdir": null,
"stdin": null
}
},
"stdout_lines": [],
"stderr": "WARNING:root:No device with given manufacturer and type found! Hint: Do you used HEX-numbers?",
"_ansible_ignore_errors": null,
"_ansible_item_label": [
"parameter_nums",
"parameter_vals",
"word_sizes"
]
}
]
},
"_ansible_verbose_always": true,
"_ansible_no_log": false,
"changed": false
}
在此示例中，只有一个结果，我可以直接访问诸如 scriptstatus.results.0.changed 之类的变量。
但是我需要循环结果。我想做的是：
- name: Show possible warnings
debug:
var: "{{ item.changed }}"
loop: "{{ scriptstatus.results }}"
但是它的输出是：
{
"changed": false,
"_ansible_no_log": false,
"_ansible_item_result": true,
"item": {
"_ansible_parsed": true,
"stderr_lines": [
"WARNING:root:No device with given manufacturer and type found! Hint: Do you used HEX-numbers?"

}
}
首先，我想知道为什么打印整个项目。但是后来我认识到了这一行
"true": "VARIABLE IS NOT DEFINED!"
使用时
- name: Show possible warnings
debug:
mgs: "{{ item.changed }}"
loop: "{{ scriptstatus.results }}"
输出只有很小的变化，例如未定义变量！丢失。例如。输出为：
{
"changed": false,
"_ansible_no_log": false,
"_ansible_item_result": true,
"item": {
"_ansible_parsed": true,

**我想实现的是，每个结果项仅输出变量 changed 的输出。示例：**
{
"msg": {
"true"
}
}
我不了解错误/问题。对我来说，我的情况与https://docs.ansible.com/ansible/latest/user_guide/playbooks_loops.html#using-register-with-a-loop
的ansible文档中描述的情况完全一样我还研究了一些类似的stackoverflow帖子，这些帖子也存在结果问题，但是没有一个能够解决我的问题。
