Toshio Kuratomi 38b3c43c68 Fix uri for change in case in response 
In python3, response fields are title cased whereas in python2 they were
not.  We return these fields to the module's caller so we need to
normalize all of them to be lower case.

This reverts the lowercase check from 454f741ef5b56cccd123e12d7b2e6fe31d47c755
as that one was only targetted as a single field.

module: uri
short_description: Interacts with webservices
description:
- Interacts with HTTP and HTTPS web services and supports Digest, Basic and WSSE
HTTP authentication mechanisms.
version_added: "1.1"
options:
url:
description:
- HTTP or HTTPS URL in the form (http|https)://host.domain[:port]/path
required: true
default: null
dest:
description:
- path of where to download the file to (if desired). If I(dest) is a
directory, the basename of the file on the remote server will be used.
required: false
default: null
user:
description:
- username for the module to use for Digest, Basic or WSSE authentication.
required: false
default: null
password:
description:
- password for the module to use for Digest, Basic or WSSE authentication.
required: false
default: null
body:
description:
- The body of the http request/response to the web service. If C(body_format) is set
to 'json' it will take an already formatted JSON string or convert a data structure
into JSON.
required: false
default: null
body_format:
description:
- The serialization format of the body. When set to json, encodes the
body argument, if needed, and automatically sets the Content-Type header accordingly.
required: false
default: raw
version_added: "2.0"
method:
description:
- The HTTP method of the request or response. It MUST be uppercase.
required: false
choices: [ "GET", "POST", "PUT", "HEAD", "DELETE", "OPTIONS", "PATCH", "TRACE", "CONNECT", "REFRESH" ]
default: "GET"
return_content:
description:
- Whether or not to return the body of the request as a "content" key in
the dictionary result. If the reported Content-type is
"application/json", then the JSON is additionally loaded into a key
called C(json) in the dictionary results.
required: false
choices: [ "yes", "no" ]
default: "no"
force_basic_auth:
description:
- The library used by the uri module only sends authentication information when a webservice
responds to an initial request with a 401 status. Since some basic auth services do not properly
send a 401, logins will fail. This option forces the sending of the Basic authentication header
upon initial request.
required: false
choices: [ "yes", "no" ]
default: "no"
follow_redirects:
description:
- Whether or not the URI module should follow redirects. C(all) will follow all redirects.
C(safe) will follow only "safe" redirects, where "safe" means that the client is only
doing a GET or HEAD on the URI to which it is being redirected. C(none) will not follow
any redirects. Note that C(yes) and C(no) choices are accepted for backwards compatibility,
where C(yes) is the equivalent of C(all) and C(no) is the equivalent of C(safe). C(yes) and C(no)
are deprecated and will be removed in some future version of Ansible.
required: false
choices: [ "all", "safe", "none" ]
default: "safe"
creates:
description:
- a filename, when it already exists, this step will not be run.
required: false
removes:
description:
- a filename, when it does not exist, this step will not be run.
required: false
status_code:
description:
- A valid, numeric, HTTP status code that signifies success of the
request. Can also be comma separated list of status codes.
required: false
default: 200
timeout:
description:
- The socket level timeout in seconds
required: false
default: 30
HEADER_:
description:
- Any parameter starting with "HEADER_" is a sent with your request as a header.
For example, HEADER_Content-Type="application/json" would send the header
"Content-Type" along with your request with a value of "application/json".
This option is deprecated as of C(2.1) and may be removed in a future
release. Use I(headers) instead.
required: false
default: null
headers:
description:
- Add custom HTTP headers to a request in the format of a YAML hash
required: false
default: null
version_added: '2.1'
others:
description:
- all arguments accepted by the M(file) module also work here
required: false
validate_certs:
description:
- If C(no), SSL certificates will not be validated. This should only
set to C(no) used on personally controlled sites using self-signed
certificates. Prior to 1.9.2 the code defaulted to C(no).
required: false
default: 'yes'
choices: ['yes', 'no']
version_added: '1.9.2'
notes:
- The dependency on httplib2 was removed in Ansible 2.1
