How to inspect a json response from Ansible URI call

This works for me.

- name: check sonar web is upuri:  url: http://sonarhost:9000/sonar/api/system/status  method: GET  return_content: yes  status_code: 200  body_format: jsonregister: resultuntil: result.json.status == "UP"retries: 10delay: 30

Notice that result is a ansible dictionary and when you set return_content=yes the response is added to this dictionary and is accessible using json key

Also ensure you have indented the task properly as shown above.

You've made the right first step by saving the output into a variable.

The next step is to use either when: or failed_when: statement in your next task, which will then switch based on the contents of the variable. There are a whole powerful set of statements for use in these, the Jinja2 builtin filters, but they are not really linked well into the Ansible documentation, or summarised nicely.

I use super explicitly named output variables, so they make sense to me later in the playbook :) I would probably write yours something like:

- name: check sonar web is up  uri:    url: http://sonarhost:9000/sonar/api/system/status    method: GET    return_content: yes    status_code: 200    body_format: json  register: sonar_web_api_status_output- name: do this thing if it is NOT up  shell: echo "OMG it's not working!"  when: sonar_web_api_status_output.stdout.find('UP') == -1

That is, the text "UP" is not found in the variable's stdout.

Other Jinja2 builtin filters I've used are:

• changed_when: "'<some text>' not in your_variable_name.stderr"
• when: some_number_of_files_changed.stdout|int > 0

The Ansible "Conditionals" docs page has some of this info. This blog post was also very informative.

As per documentation at https://docs.ansible.com/ansible/latest/modules/uri_module.html

Whether or not to return the body of the response as a "content" key in the dictionary result. Independently of this option, if the reported Content-type is "application/json", then the JSON is always loaded into a key called json in the dictionary results.
