Interacting with SQS
Query API
The SQS web service API is made available through three interfaces: REST, Query, and SOAP. In this book we use the Query interface.
The SQS service implementation presented in this chapter uses
the Query API functionality implemented in the AWS Ruby module. The
AWS module includes that perform
authentication, transmission, and response checking of Query API
requests. These methods are presented in Query API Implementation” in Chapter 2.
Amazon uses version identifiers to label different versions of
most of its service APIs. By assigning each API version its own
identifier, Amazon can continue to develop and change the APIs without
without breaking AWS client implementations that use the older
versions. In this book, we use the SQS API version: 2007-05-01.
SQS Implementation Stub
In this chapter, we will gradually build up a complete
implementation class called SQS
that you can use to interact with the SQS service. Example 8-1 is a basic code stub that defines the
SQS class, to which we will add API
implementation methods as we proceed through the chapter. Save the
class to a file named SQS.rb in
the same directory as the AWS
module file AWS.rb, defined in
Chapter 2.
Example 8-1. SQS class stub: SQS.rb
require 'AWS' class SQS include AWS # Include the AWS module as a mixin ENDPOINT_URI = URI.parse("https://queue.amazonaws.com/") API_VERSION = '2007-05-01' SIGNATURE_VERSION = '1' HTTP_METHOD = 'POST' # 'GET' # SQS API implementation methods will go here... ...Become an O’Reilly member and get unlimited access to this title plus top books and audiobooks from O’Reilly and nearly 200 top publishers, thousands of courses curated by job role, 150+ live events each month,
