public class JSONRPC2Request
extends JSONRPC2Message

Represents a JSON-RPC 2.0 request.

A request carries four pieces of data:

method The name of the remote method to call.
params The required method parameters (if any), which can be packed into a JSON array or object.
id An identifier which is echoed back to the client with the response.
jsonrpc A string indicating the JSON-RPC protocol version set to "2.0".

Here is a sample JSON-RPC 2.0 request string:

 {
    "method"  : "makePayment",
    "params"  : { "recipient" : "Penny Adams", "amount":175.05 },
    "id"      : "0001",
    "jsonrpc" : "2.0"
 }

This class provides two methods to obtain a request object:

Pass a JSON-RPC 2.0 request string to the static parse(java.lang.String) method, or
Invoke one of the constructors with the appropriate arguments.

Example 1: Parsing a request string:

 String jsonString = "{\"method\":\"makePayment\"," +
                     "\"params\":{\"recipient\":\"Penny Adams\",\"amount\":175.05}," +
                     "\"id\":\"0001\","+
                     "\"jsonrpc\":\"2.0\"}";

 JSONRPC2Request req = null;

 try {
         req = JSONRPC2Request.parse(jsonString);

 } catch (JSONRPC2ParseException e) {
         // handle exception
 }

Example 2: Recreating the above request:

 String method = "makePayment";
 Map<String,Object> params = new HashMap<String,Object>();
 params.put("recipient", "Penny Adams");
 params.put("amount", 175.05);
 String id = "0001";

 JSONRPC2Request req = new JSONRPC2Request(method, params, id);

 System.out.println(req);

The mapping between JSON and Java entities (as defined by the underlying JSON Smart library):

     true|false  <--->  java.lang.Boolean
     number      <--->  java.lang.Number
     string      <--->  java.lang.String
     array       <--->  java.util.List
     object      <--->  java.util.Map
     null        <--->  null
