Getting variable values from url - ansible

Question

i am new to ansible and i am trying to achieve the following,
This is the sample playbook, here i am creating a reg key called "test" under HKLM:\SOFTWARE\myapp\Desk\ and i am adding 2 entries with items called hello and hi and i am assigning single same value "world" to both hello and hi.
i want to get the value for hello and hi from some file which will be stored in a repository or some url ..the value will be different for hello and hi.. is this possible ?
---
- hosts: web
tasks:
- name: Create and add reg entries
win_regedit:
path: HKLM:\SOFTWARE\myapp\Desk\Test
entry: "{{ item }}"
data: world
type: string
state: present
with_items:
- hello
- hi
Update:
Some improvement here for a newbie, i am able to iterate through with_items with key value , but i want to have a file with key:value and i want the ansible to iterate through all the left side keys and create them and also fill them with the right side values..that is the entry in win_Regedit should have key and data should have values

- hosts: web
tasks:
- name: Create and add reg entries
win_regedit:
path: HKLM:\SOFTWARE\myapp\Desk\Test
entry: "{{ item.regkey }}"
data: "{{ item.regvalue}}"
type: string
state: present
with_items:
- regkey: hello
regvalue: world
- regkey: hi
regvalue: universe

Answer 1

To include variable from some file, you can use the include_vars module:
include_vars:
file: vars.yml
Edit What you want to do is probably something like below (did not try the win_regedit as I don't have any windows node):
Create a vars.yml:
---
var1: 'key1'
var2: 'key2'
d1: "{
'{{var1}}': 'val1',
'{{var2}}': 'val2'
}"
Then launch the following playbook (see the with_dict statement):
---
- hosts: localhost
remote_user: my_user
tasks:
- name: pull var_file
url: http://example.com/path/to/vars
dest: /path/to/vars.yml
mode: 0440
- name: include_vars
include_vars:
/path/to/vars.yml
- name: Create and add reg entries
win_regedit:
path: HKLM:\SOFTWARE\myapp\Desk\Test
entry: "{{ item.key }}"
data: "{{ item.value}}"
type: string
state: present
with_dict: "{{d1}}"
Kudos to this answer for the with_dict trick

Answer 2

Use uri module.
---
- hosts: localhost
remote_user: my_user
tasks:
- name: pull var_file
uri:
url: http://example.com/path/to/vars
method: GET
return_content: yes
register: vars_from_url
- name: Create and add reg entries
win_regedit:
path: HKLM:\SOFTWARE\myapp\Desk\Test
entry: "{{ item.key }}"
data: "{{ item.value}}"
type: string
state: present
with_dict: "{{ vars_from_url.content }}"
