Using Rapidjson in Cocos2D-X: Creating a JSON Document in Code and Serializing it

This is based on Cocos2D-X version 3.2

This import is necessary for creating a JSON document and manipulating it:

#include "external/json/document.h"

These imports are necessary for Serialization:

#include "external/json/writer.h" #include "external/json/stringbuffer.h"

Example code:

rapidjson::Document jsonDoc; // create the object jsonDoc.SetObject(); // flag it as an object rather than an array,a necessary step for Serialization // to set a value (using Cocos2D-X String type in this example here) String* key = “key”; String* value = “value” jsonDoc.AddMember(key->getCString(),value->getCString(),jsonDoc.GetAllocator()); // to Serialize to JSON String rapidjson::StringBuffer sb; rapidjson::Writer<rapidjson::StringBuffer> writer(sb); jsonDoc.Accept(writer); String* jsonString = String::create(sb.GetString());
