NAME
SimpleDB::Class::HTTP - The network interface to the SimpleDB service.
VERSION
version 0.0802
SYNOPSIS
use SimpleDB::Class::HTTP;
my $http = SimpleDB::Class::HTTP->new(secret_key=>'abc', access_key=>'123');
my $hashref = $http->send_request('CreateDomain', {DomainName => 'my_new_domain'});DESCRIPTION
This class will let you quickly and easily inteface with AWS SimpleDB. It throws exceptions from SimpleDB::Class::Exception, but other than that doesn't rely on any of the other modules in the SimpleDB::Class system, which means it's very light weight. Although we haven't run any benchmarks, it should outperform any of the other Perl modules that exist today.
METHODS
The following methods are available from this class.
new ( params )
params
A hash containing the parameters to pass in to this method.
access_key
The access key given to you from Amazon when you sign up for the SimpleDB service at this URL: http://aws.amazon.com/simpledb/
secret_key
The secret access key given to you from Amazon.
simpledb_uri
The constructor that SimpleDB::Class will connect to. Defaults to:
URI->new('https://sdb.amazonaws.com/')access_key ( )
Returns the access key passed to the constructor.
secret_key ( )
Returns the secret key passed to the constructor.
simpledb_uri ( )
Returns the URI object passed into the constructor that SimpleDB::Class will connect to. Defaults to:
URI->new('https://sdb.amazonaws.com/')user_agent ( )
Returns the LWP::UserAgent object that is used to connect to SimpleDB. It's cached here so it doesn't have to be created each time.
construct_request ( action, [ params ] )
Returns a string that contains the HTTP post data ready to make a request to SimpleDB. Normally this is only called by send_request(), but if you want to debug a SimpleDB interaction, then having access to this method is critical.
action
The action to perform on SimpleDB. See the "Operations" section of the guide located at http://docs.amazonwebservices.com/AmazonSimpleDB/2009-04-15/DeveloperGuide/.
params
Any extra prameters required by the operation. The normal parameters of Action, AWSAccessKeyId, Version, Timestamp, SignatureMethod, SignatureVersion, and Signature are all automatically provided by this method.
send_request ( action, [ params ] )
Creates a request, and then sends it to SimpleDB. The response is returned as a hash reference of the raw XML document returned by SimpleDB. Automatically attempts 5 cascading retries on connection failure.
Throws SimpleDB::Class::Exception::Response and SimpleDB::Class::Exception::Connection.
action
See create_request() for details.
params
See create_request() for details.
handle_response ( body, headers )
Returns a hashref containing the response from SimpleDB.
Throws SimpleDB::Class::Exception::Response.
body
The XML returned by SimpleDB.
headers
The HTTP headers.
