* Import url(lib|parse|lib2) if needed by the module rather than relying
on module_utils.urls to do so.
* Remove stdlib modules from requirements
* Use the if __name__ conditional for invoking main()
body_format is a new optional argument that enables handling of JSON or
YAML serialization format for the body argument.
When set to either 'json' or 'yaml', the body argument can be a dict or list.
The body will be encoded, and the Content-Type HTTP header will be set,
accordingly to the body_format argument.
Example:
- name: Facette - Create memory graph
uri:
method: POST
url: http://facette/api/v1/library/graphs
status_code: 201
body_format: json
body:
name: "{{ ansible_fqdn }} - Memory usage"
attributes:
Source": "{{ ansible_fqdn }}"
link: "1947a490-8ac6-4bf2-47c1-ff74272f8b32"
When using the "creates" option with the uri module, set changed
to False if the file already exists. This behavior is consistent with
other modules which use "creates", such as command and shell.
consider the following response body (content) of a REST/JSON webservice containing escaped quotation marks:
```json
{ "key": "\"works\"" }
```
decoding this string not as raw will lose the backslash as JSON escape. later json.loads will fail to parse.
Inspired by [this thread](https://groups.google.com/forum/#!topic/ansible-project/kymtiloDme4) on the mailing list and the following python shell code:
```python
import json
string=r'{ "key": "\"works\"" }'
json.loads(string)
json.loads(string.decode('raw_unicode_escape'))
json.loads(string.decode('unicode_escape'))
```
Also moves the calculation of the destination file name until after
the slurp of the file contents, since the source as returned by slurp
may now be different, so we want to use that expanded path locally.
Fixes#8942
The content of the sha256sum attribute should be lowered before comparing it with the calculated sha256sum.
In the following example the used sha256sum uses ABC.. and not abc.. and the check failed. This should not happen.
