Cocos2d-3.x_读取json文件

概述测试的data.json文件的内容如下： [{"name":"zhangsan", "age":20}, {"name":"lisi", "age":30}] #ifndef __HELLOWORLD_SCENE_H__#define __HELLOWORLD_SCENE_H__#include "cocos2d.h"USING_NS_CC;class HelloWorld : p

测试的data.Json文件的内容如下：

[{"name":"zhangsan","age":20},{"name":"lisi","age":30}]

#ifndef __HELLOWORLD_SCENE_H__#define __HELLOWORLD_SCENE_H__#include "cocos2d.h"USING_NS_CC;class HelloWorld : public cocos2d::Layer{public:    static cocos2d::Scene* createScene();    virtual bool init();	voID readJsonByCocosAPI();    CREATE_FUNC(HelloWorld);private:	LabelTTF *pLabel;};#endif // __HELLOWORLD_SCENE_H__

#include "HelloWorldScene.h"#include "Json/document.h"Scene* HelloWorld::createScene(){    auto scene = Scene::create();    auto layer = HelloWorld::create();    scene->addChild(layer);    return scene;}bool HelloWorld::init(){    if ( !Layer::init() )    {        return false;    }        Size visibleSize = Director::getInstance()->getVisibleSize();    Vec2 origin = Director::getInstance()->getVisibleOrigin();	pLabel = LabelTTF::create("","Arial",30);	pLabel->setposition(visibleSize/2.0);	this->addChild(pLabel);	this->readJsonByCocosAPI();    return true;}voID HelloWorld::readJsonByCocosAPI(){	rAPIdJson::document doc;	doc.Parse<0>(fileUtils::getInstance()->getStringFromfile("data.Json").c_str());	// 获得第一个对象的name和age的属性	int index = 0;	const char *ch = doc[index]["name"].GetString();	int iage = doc[index]["age"].GetInt();	std::ostringstream str;	str << "name:";	str << ch;	str << ",";	str << "age:";	str << iage;	pLabel->setString(str.str());	// 遍历Json数组	for (int i = 0; i < doc.Size(); i ++)	{		const char *name= doc[i]["name"].GetString();		int age = doc[i]["age"].GetInt();		log("name:%s,age:%d",name,age);	}}
