Class JSONPObject

java.lang.Object

com.alibaba.fastjson2.JSONPObject

Direct Known Subclasses:

JSONPObject

public class JSONPObject
extends java.lang.Object

JSONPObject is used to represent JSONP (JSON with Padding) data structure.

JSONP is a technique for safely requesting data from another domain. It wraps JSON data in a function call to bypass the same-origin policy that prevents direct access to resources from different domains.

Example usage:

 // Create a JSONP object
 JSONPObject jsonp = new JSONPObject("callback");
 jsonp.addParameter(new JSONObject().fluentPut("id", 1).fluentPut("name", "test"));

 // Serialize to JSONP string
 String jsonpString = jsonp.toString(); // "callback({\"id\":1,\"name\":\"test\"})"

 // Parse from JSONP string
 JSONPObject parsed = JSON.parseObject(jsonpString, JSONPObject.class);
