在Cocos2dx3.0下,JSON解析库官方已经集成好了,我们引用就OK。

JSON文件hello.json内容

{"pets":["dog","cat"],"stuInfo":{"stuAge":"23","stuName":"zhangsan","birthday":"1990-01-12"},"username":"tomsfff","other":[true,30]}


.h头文件

#include "cocos-ext.h"#include "json/document.h"


.cpp

 //获取文件路径        const char* file_path = FileUtils::getInstance()->fullPathForFilename("hello.json").c_str();       log("external file path = %s",file_path);                rapidjson::Document d1;        std::string contentStr = FileUtils::getInstance()->getStringFromFile(file_path);        d1.Parse<0>(contentStr.c_str());        //打印JSon文件的内容        printf("%s\n",contentStr.c_str());                //获取JSon中数组的方法        const rapidjson::Value& v = d1["pets"];        if (v.IsArray()) {            //这里一定要注意  变量i 一定要是   unsigned int  不然会报错            for (unsigned int i = 0; i< v.Size(); ++i) {                                 const rapidjson::Value &val = v[i];                log("%s",val.GetString());            }                    }else        {            const rapidjson::Value& val = v["stuAge"];            log("val.GetString() = %s",val.GetString());                    }
