本次Json生成工具升级版是经过封装，只需传入2个vector和1个int值即可完成Json文件的生成。

2、具体代码

1）.h文件

#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(const std::vector<std::string>& strname,const std::vector<std::string>& strContent,const int count);};

2）.cpp文件

#include "JsonMake.h"bool JsonMake::init(){    bool bRet = false;    do{        bRet = true;    }while(0);    return bRet;}std::string JsonMake::getJsonMyBaodanMain(const std::vector<std::string>& strname,const int count){        rAPIdJson::document document;    document.Setobject();    CCASSERT(strname.size() == strContent.size(),"strname.size() != strContent.size()");    log("strname.size = %lu,strContent.size = %lu",strname.size(),strContent.size());    rAPIdJson::document::AllocatorType& allocator = document.GetAllocator();    rAPIdJson::Value objectROOT(rAPIdJson::kArrayType);    log("count = %d",count);    for(int i = 0; i < count; i++)    {        rAPIdJson::Value object(rAPIdJson::kObjectType);        for(int j = 0 ; j < strname.size(); j++)        {            object.AddMember(strname.at(j).c_str(),strContent.at(j).c_str(),allocator);        }        objectROOT.PushBack(object,allocator);    }        document.AddMember("info",objectROOT,allocator);    StringBuffer buffer;    rAPIdJson::Writer<StringBuffer> writer(buffer);    document.Accept(writer);    log("%s",buffer.GetString());    return StringUtils::format("%s",buffer.GetString());}

3、使用方法

只需在HelloWorldScene.cpp中的init函数中添加如下代码：

        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();        std::vector<std::string> strname = getStrname();        std::vector<std::string> strContent = getStrContent();        auto str = JsonMake->getJsonMyBaodanMain(strname,strContent,10);        auto length = str.length();        fwrite(str.c_str(),length,1,fp);        fclose(fp);

然后再添加以下两个函数的定义，当然在.h中的声明是必不可少的呀！

std::vector<std::string> HelloWorld::getStrname(){    std::vector<std::string> strname;    strname.push_back("baodanTitle");    strname.push_back("baodanStatue");    strname.push_back("insurancename");    strname.push_back("takeEffectTime");    strname.push_back("timelimit");    strname.push_back("saleUnit");    strname.push_back("institutionAddress");    strname.push_back("toubaoPerson");    strname.push_back("beibaoPerson");    strname.push_back("forehead");    strname.push_back("premium");    return strname;}std::vector<std::string> HelloWorld::getStrContent(){    std::vector<std::string> strContent;    strContent.push_back("保单号");    strContent.push_back("保单状态");    strContent.push_back("险种名称");    strContent.push_back("生效日期");    strContent.push_back("保险期限");    strContent.push_back("销售单位");    strContent.push_back("机构地址");    strContent.push_back("投保人");    strContent.push_back("被保人");    strContent.push_back("保额");    strContent.push_back("保费");        return strContent;}
