Zend Framework: Zend_Json_Server Component Proposal

Table of Contents

1. Overview

Zend_Json_Server makes it easy to build a JSON-RPC server. This proposal is about extending this component to also support JSONP.

2. References

• JSONP: JSON With Padding

3. Component Requirements, Constraints, and Acceptance Criteria

• This component will be ale to process JSON requests that have the request data in GET instead of POST.
• This component will allow the client to provide the name of his callback method.

4. Dependencies on Other Framework Components

• Zend_Json_Server

5. Theory of Operation

When a request is received by the Zend_Json_Server, it is checked for either being a JSON-RPC request or a JSONP request (request resides in POST or in GET). A JSONP request has an extra parameter, the name of the callback method. Once a JSONP request is processed the response data should be wrapped in a function call, calling the callback method.

6. Milestones / Tasks

• Milestone 1: design notes will be published here
• Milestone 2: Working prototype checked into the incubator supporting all use cases.
• Milestone 3: Unit tests exist, work, and are checked into SVN.
• Milestone 4: Initial documentation exists.

7. Class Index

• Zend_Json_Server
• Zend_Json_Server_Request
• Zend_Json_Server_Smd

8. Use Cases

Zend_Json_Server should keep working as it does today. You create the server, and let it handle the request.
