DESCRIPTION
This REST Client role makes REST connectivity easy.
Role::REST::Client will handle encoding and decoding when using the HTTP verbs.
GET
HEAD
PUT
POST
DELETE
OPTIONS
Currently Role::REST::Client supports these encodings
application/json
application/x-www-form-urlencoded
application/xml
application/yaml
x-www-form-urlencoded only works for GET and POST, and only for encoding, not decoding.
Responses which claim to not be serialised data (eg "text/plain", "application/octet-stream") will by
default not be serialised. When the response is none of these, and it is impossible to determine what
encoding is used, the content will be treated as JSON by default.
NAME
Role::REST::Client - REST Client Role
METHODS
methods
Role::REST::Client implements the standard HTTP 1.1 verbs as methods
These methods can NOT have a request body
get
head
These methods can take a request body.
post
put
delete
options
All methods take these parameters
url - The REST service
data - The data structure (hashref, arrayref) to send. The data will be encoded
according to the value of the I<type> attribute.
args - hashref with arguments to augment the way the call is handled.
args - the optional argument parameter can have these entries
deserializer - if you KNOW that the content-type of the response is incorrect,
you can supply the correct content type, like
my $res = $self->post('/foo/bar/baz', {foo => 'bar'}, {deserializer => 'application/yaml'});
Alternatively, if you KNOW that the response is not serial data, you can
disable deserialization by setting this to undef.
preserve_headers - set this to true if you want to keep the headers between calls
All methods return a response object dictated by _rest_response_class. Set to
Role::REST::Client::Response by default.
ATTRIBUTES
user_agent
sub _build_user_agent { HTTP::Thin->new }
A User Agent object which has a "->request" method suitably compatible with HTTP::Tiny. It should accept
arguments like this: "$ua->request($method, $uri, $opts)", and needs to return a hashref as HTTP::Tiny
does, or an HTTP::Response object. To set your own default, use a "_build_user_agent" method.
server
URL of the REST server.
e.g. 'http://localhost:3000'
type
MIME Content-Type header,
e.g. application/json
persistent_headers
$self->set_persistent_header('Header' => 'foo', ... );
$self->get_persistent_header('Header-Name');
$self->has_no_persistent_headers;
$self->clear_persistent_headers;
A hashref containing headers you want to use for all requests. Use the methods described above to
manipulate it.
To set your own defaults, override the default or call "set_persistent_header()" in your "BUILD" method.
has '+persistent_headers' => (
default => sub { ... },
);
httpheaders
$self->set_header('Header' => 'foo', ... );
$self->get_header('Header-Name');
$self->has_no_headers;
$self->clear_headers;
You can set any http header you like with set_header, e.g. $self->set_header($key, $value) but the
content-type header will be overridden.
http_headers will be reset after each request, unless there's a reserve_headers argument, but it's a
hack. The recommended way to keep headers across requests is to store them in the persistent_headers.
$self->httpheaders will return the combined hashref of persistent_headers and what's been added with
set_header.
For historical reasons, the two methods clear_headers and reset_headers are equal. Both will clear the
headers for the current request, but NOT the persistent headers.
To clear ALL headers, use
$self->clear_all_headers;
clientattrs
Attributes to feed the user agent object (which defaults to HTTP::Thin)
e.g. {timeout => 10}
serializer_class
You can override the serializer class and use your own. Default is 'Role::REST::Client::Serializer'
serializer_options
Options for the serializer instantiation.
