REST::Client(3) User Contributed Perl Documentation REST::Client(3)
NAME
REST::Client - A simple client for interacting with RESTful http/https resources
SYNOPSIS
use REST::Client;
#The basic use case
my $client = REST::Client->new();
$client->GET('http://example.com/dir/file.xml');
print $client->responseContent();
#A host can be set for convienience
$client->setHost('http://example.com');
$client->PUT('/dir/file.xml', '<example>new content</example>');
if( $client->responseCode() eq '200' ){
print "Updated\n";
}
#custom request headers may be added
$client->addHeader('CustomHeader', 'Value');
#response headers may be gathered
print $client->responseHeader('ResponseHeader');
#X509 client authentication
$client->setCert('/path/to/ssl.crt');
$client->setKey('/path/to/ssl.key');
#add a CA to verify server certificates
$client->setCa('/path/to/ca.file');
#you may set a timeout on requests, in seconds
$client->setTimeout(10);
#options may be passed as well as set
$client = REST::Client->new({
host => 'https://example.com',
cert => '/path/to/ssl.crt',
key => '/path/to/ssl.key',
ca => '/path/to/ca.file',
timeout => 10,
});
$client->GET('/dir/file', {CustomHeader => 'Value'});
# Requests can be specificed directly as well
$client->request('GET', '/dir/file', 'request body content', {CustomHeader => 'Value'});
# Requests can optionally automatically follow redirects and auth, defaults to
# false
$client->setFollow(1);
#It is possible to access the L<LWP::UserAgent> object REST::Client is using to
#make requests, and set advanced options on it, for instance:
$client->getUseragent()->proxy(['http'], 'http://proxy.example.com/');
DESCRIPTION
REST::Client provides a simple way to interact with HTTP RESTful resources.
METHODS
Construction and setup
new ( [%$config] )
Construct a new REST::Client. Takes an optional hash or hash reference or config flags.
Each config flag also has get/set accessors of the form getHost/setHost,
getUseragent/setUseragent, etc. These can be called on the instantiated object to change
or check values.
The config flags are:
host
A default host that will be prepended to all requests. Allows you to just specify the
path when making requests.
The default is undef - you must include the host in your requests.
timeout
A timeout in seconds for requests made with the client. After the timeout the client
will return a 500.
The default is 5 minutes.
cert
The path to a X509 certificate file to be used for client authentication.
The default is to not use a certificate/key pair.
key The path to a X509 key file to be used for client authentication.
The default is to not use a certificate/key pair.
ca The path to a certificate authority file to be used to verify host certificates.
The default is to not use a certificates authority.
pkcs12
The path to a PKCS12 certificate to be used for client authentication.
pkcs12password
The password for the PKCS12 certificate specified with 'pkcs12'.
follow
Boolean that determins whether REST::Client attempts to automatically follow
redirects/authentication.
The default is false.
useragent
An LWP::UserAgent object, ready to make http requests.
REST::Client will provide a default for you if you do not set this.
addHeader ( $header_name, $value )
Add a custom header to any requests made by this client.
buildQuery ( [...] )
A convienience wrapper around URI::query_form for building query strings from a variety of
data structures. See URI
Returns a scalar query string for use in URLs.
Request Methods
Each of these methods makes an HTTP request, sets the internal state of the object, and
returns the object.
They can be combined with the response methods, such as:
print $client->GET('/search/?q=foobar')->responseContent();
GET ( $url, [%$headers] )
Preform an HTTP GET to the resource specified. Takes an optional hashref of custom request
headers.
PUT ($url, [$body_content, %$headers] )
Preform an HTTP PUT to the resource specified. Takes an optional body content and hashref
of custom request headers.
PATCH ( $url, [$body_content, %$headers] )
Preform an HTTP PATCH to the resource specified. Takes an optional body content and
hashref of custom request headers.
POST ( $url, [$body_content, %$headers] )
Preform an HTTP POST to the resource specified. Takes an optional body content and hashref
of custom request headers.
DELETE ( $url, [%$headers] )
Preform an HTTP DELETE to the resource specified. Takes an optional hashref of custom
request headers.
OPTIONS ( $url, [%$headers] )
Preform an HTTP OPTIONS to the resource specified. Takes an optional hashref of custom
request headers.
HEAD ( $url, [%$headers] )
Preform an HTTP HEAD to the resource specified. Takes an optional hashref of custom
request headers.
request ( $method, $url, [$body_content, %$headers] )
Issue a custom request, providing all possible values.
Response Methods
Use these methods to gather information about the last requset performed.
responseCode ()
Return the HTTP response code of the last request
responseContent ()
Return the response body content of the last request
responseHeaders()
Returns a list of HTTP header names from the last response
responseHeader ( $header )
Return a HTTP header from the last response
responseXpath ()
A convienience wrapper that returns a XML::LibXML xpath context for the body content.
Assumes the content is XML.
TODO
Caching, content-type negotiation, readable handles for body content.
