Extract part of JSON in ansible playbook - json

Question

I want to extract a part from a json extra vars input and use this as a variable in further commands.
The extra vars being parsed towards ansible is:
{
"problemUrl": "https://xxxxx.xxxxxxxxx-xxxxx.xxxx/e/58b59a93-xxxx-xxxx-xxxx-91bb5ca1f41c/#problems/problemdetails;pid=-5484403941961857966_1631165040000V2",
}
I want to extract the part -5484403941961857966_1631165040000V2 and store it into a variable.
- name: get pid from URL
set_fact:
pidproblem: "{{ problemUrl | urlsplit('fragment') | regex_search('pid=(.+)', '\\1') }}"
- name: show pid
debug:
var: pidproblem[0]
- name: update problem with output
when: state == "OPEN"
uri:
url: https://xxxxx.xxxxxxxxx-xxxxx.xxxx/e/58b59a93-xxxx-xxxx-xxxx-91bb5ca1f41c/api/v2/problems/"{{ pidproblem[0] }}"/comments
method: POST
headers:
Content-Type: application/json; charset=utf-8
Authorization: Api-Token xxxxx
body_format: json
body: "{\"message\":\"TEST\",\"context\":\"TEST\"}"
Could the issue reside in the fact that the id is subsituded as "6551567569324750926_1631192580000V2" instead of 6551567569324750926_1631192580000V2?
"url": "https://xxxxx.xxxxxxxxx-xxxxx.xxxx/e/58b59a93-xxxx-xxxx-xxxx-91bb5ca1f41c/api/v2/problems/\"6551567569324750926_1631192580000V2\"/comments"

Answer 1

There is a urlsplit filter which can split a URL into known segments. We can use this to break down the URL and get the last fragment, i.e.
"{{ problemUrl | urlsplit('fragment') }}"
Gives...
problems/problemdetails;pid=-5484403941961857966_1631165040000V2
Now this gives us a more "manageable" string. We can do a regex_search (with groups) on this, to get the pid, like:
- name: get pid from URL
set_fact:
pid: "{{ problemUrl | urlsplit('fragment') | regex_search('pid=(-.+)', '\\1') }}"
- name: show pid
debug:
var: pid[0]
- name: update problem with output
uri:
url: "https://xxxxx.xxxxxxxxx-xxxxx.xxxx/e/58b59a93-xxxx-xxxx-xxxx-91bb5ca1f41c/api/v2/problems/{{ pid[0] }}/comments"
# other params

Not super-reliable as we don't know how your url can change, but you could use some regex filter to extract the pid value:
- hosts: localhost
vars:
problemUrl: '{ "problemUrl": "https://xxxxx.xxxxxxxxx-xxxxx.xxxx/e/58b59a93-xxxx-xxxx-xxxx-91bb5ca1f41c/#problems/problemdetails;pid=-5484403941961857966_1631165040000V2;other=false" }'
tasks:
- name: set_fact some paramater
set_fact:
pid: "{{ (problemUrl | from_json).problemUrl | regex_replace('.*pid=(?P<pid>[^;]*).*', '\\g<pid>') }}"
- name: "update"
debug:
msg: "{{ pid }}"
