问题
I am pulling JSON via the URI module and want to write the received content out to a file. I am able to get the content and output it to the debugger so I know the content has been received, but I do not know the best practice for writing files.
回答1:
You could use the copy module, with the content parameter:
- copy: content="{{ your_json_feed }}" dest=/path/to/destination/file
The docs here: copy module
回答2:
Unless you are writing very small files, you should probably use templates.
Example:
- name: copy upstart script
template:
src: myCompany-service.conf.j2
dest: "/etc/init/myCompany-service.conf"

Based on Ramon's answer I run into an error. The problem where spaces in the JSON I tried to write I got it fixed by changing the task in the playbook to look like:
- copy:
content: "{{ your_json_feed }}"
dest: "/path/to/destination/file"
As of now I am not sure why this was needed. My best guess is that it had something to do with how variables are replaced in Ansible and the resulting file is parsed.

We can directly specify the destination file with the dest option now. In the below example, the output json is stored into the /tmp/repo_version_file
- name: Get repository file repo_version model to set ambari_managed_repositories=false
uri:
url: 'http://<server IP>:8080/api/v1/stacks/HDP/versions/3.1/repository_versions/1?fields=operating_systems/*'
method: GET
force_basic_auth: yes
user: xxxxx
password: xxxxx
headers:
"X-Requested-By": "ambari"
"Content-type": "Application/json"
status_code: 200
dest: /tmp/repo_version_file
