从 json 输出中提取一个变量,然后使用 ansible 调试和注册输出 [英] extracting a variable from json output then debug and register the outout with ansible
问题描述
我在执行 curl 解析并注册回 ansible 后遇到从 json 输出中提取的变量之一的问题
Hi I have a problem of getting one of the variables extracted from a json output after doing a curl to be parsed and registered back to ansible
剧本:
- name: debug stdout
debug:
msg: "{{ result.stdout | from_json }}"
register: dataresult
- name: debug fact
debug:
msg: "{{ dataresult.data.start_time_string }}"
输出:
TASK [backup_api : debug stdout]
***********************************************
task path: /home/ansible/cm-dha/roles/backup_api/tasks/main.yml:36
ok: [127.0.0.1] => {
"msg": {
"data": [
{
"backup_id": 40362,
"certified": null,
"instance_id": 148,
"start_time": 1506985211,
"start_time_string": "10/03/2017 03:00:11 am"
}
],
"timestamp": 1507022232
}
}
错误:
致命:[127.0.0.1]:失败!=> {失败":真的,"msg": "字段 'args' 有一个无效值,它似乎包含一个未定义的变量.错误是:'dict object' 没有属性 'data'\n\n错误似乎出现在 '/home/ansible/cm-dha/roles/backup_api/tasks/main.yml':第 48 行,第 5 列,但可能\n位于文件中的其他位置,具体取决于确切的语法问题.\n\n违规行似乎是:\n\n\n - 名称:调试事实\n ^ 此处\n"
fatal: [127.0.0.1]: FAILED! => { "failed": true, "msg": "the field 'args' has an invalid value, which appears to include a variable that is undefined. The error was: 'dict object' has no attribute 'data'\n\nThe error appears to have been in '/home/ansible/cm-dha/roles/backup_api/tasks/main.yml': line 48, column 5, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n - name: debug fact\n ^ here\n"
尝试提取值 start_time_string 时发生错误
The error is happening when trying to extract the value start_time_string
那么怎么做可能是因为我尝试了太多东西,比如使用 with_items、with_dict、模拟 data[] 输出进行调试,甚至执行 json 查询但没有成功
so how to do it probably as I tried too many things like using with_items, with_dict , simulating the data[] output to debug and even doing a json query but without success
所以这里有什么帮助吗?
so any help here?
推荐答案
不要使用 debug
来分配事实,而是使用 set_fact
:
Don't use debug
to assign facts, use set_fact
instead:
- name: debug stdout
set_fact:
dataresult: "{{ result.stdout | from_json }}"
- name: debug fact
debug:
msg: "{{ dataresult.data[0].start_time_string }}"
