1、JsonMake类

//.h
#include "cocos2d.h"
#include "../cocos2d/external/json/document.h"
#include "../cocos2d/external/json/writer.h"
#include "../cocos2d/external/json/stringbuffer.h"

USING_NS_CC;
using namespace rapidjson;

class JsonMake : public Ref
{
public:
    CREATE_FUNC(JsonMake);
    virtual bool init();
    std::string getJsonMyBaodanMain();
};
//.cpp
#include "JsonMake.h"
bool JsonMake::init()
{
    bool bRet = false;
    do{
        
        
        
        bRet = true;
    }while(0);
    return bRet;
}

std::string JsonMake::getJsonMyBaodanMain()
{    
    rapidjson::Document document;
    document.SetObject();
    
    rapidjson::Document::AllocatorType& allocator = document.GetAllocator();
    rapidjson::Value object1(rapidjson::kObjectType);
    rapidjson::Value object2(rapidjson::kObjectType);
    rapidjson::Value object3(rapidjson::kObjectType);
    rapidjson::Value object4(rapidjson::kArrayType);
    
    object1.AddMember("Name", "Yuxikuo", allocator);
    object1.AddMember("Age", "18", allocator);
    object1.AddMember("Sex", "man", allocator);
    
    object2.AddMember("Name", "WangDongGe", allocator);
    object2.AddMember("Age", "32", allocator);
    object2.AddMember("Sex", "woman", allocator);

    object3.AddMember("Name", "zhanhong", allocator);
    object3.AddMember("Age", "20", allocator);
    object3.AddMember("Sex", "man", allocator);

    object4.PushBack(object1,allocator);
    object4.PushBack(object2,allocator);
    object4.PushBack(object3,allocator);
    
    document.AddMember("info", object4, allocator);
    
    StringBuffer buffer;
    rapidjson::Writer<StringBuffer> writer(buffer);
    document.Accept(writer);
    log("%s",buffer.GetString());
    
    return StringUtils::format("%s",buffer.GetString());

}

2、使用方法

将生成的json文件保存的本地

auto path = FileUtils::getInstance()->getWritablePath();
        log("path = %s",path.c_str());
        path.append("myBaodanMain.json");
        FILE* fp = std::fopen(path.c_str(), "at+");
        CCASSERT(fp != NULL, "file open error");
        
        auto jsonMake = JsonMake::create();
        auto str = jsonMake->getJsonMyBaodanMain();
        auto length = str.length();
        fwrite(str.c_str(), length, 1 ,fp);
        fclose(fp);

3、结果

//json
{"info":[{"Name":"Yuxikuo","Age":"18","Sex":"man"},{"Name":"WangDongGe","Age":"32","Sex":"woman"},{"Name":"zhanhong","Age":"20","Sex":"man"}]}
