cocos2d-x json解析

版本cocos2d-x2.1.3

今天做一个项目要用到json解析，遇到一点问题，浪费了一下午的时间，现在记录下来，以免遗忘。

使用的是cocos2d-x自带的json解析类，只能解析不能生成，新建一个项目，首先做两个准备（我就是忘了做，浪费一下午时间），第一、点击新建的项目右键->属性

第二个在附加依赖项中添加libExtensions.lib、

然后代码部分就简单了.h文件中添加

#include "cocos2d.h"
#include "spineJson.h"
#include "cocos-ext.h"
USING_NS_CC_EXT;
USING_NS_CC;

.cpp文件中添加

 AllocConsole();  
        freopen("CONIN$", "r", stdin);  
        freopen("CONOUT$", "w", stdout);  
        freopen("CONOUT$", "w", stderr); 
        const char* text= "{"record":{"data":20130101,"rate":23,"buy":1},"record":{"data":45,"rate":67,"buy":1},"record":{"data":45,"rate":76,"buy":10}}";
        Json* root= cocos2d::extension::Json_create(text);
        Json* _record=root->child;
        while(_record)
        {
            Json* _date=cocos2d::extension::Json_getItem(_record, "data");
         if(_date->type==Json_Number)
         {
          int date= _date->valueint;
          CCLOG("Date: %d",date);
         }

         Json* _rate=Json_getItem(_record, "rate");
         if(_rate->type==Json_Number)
         {
          int rate=_rate->valueint;
          CCLOG("Rate: %d",rate);
         }
         Json* _buy=Json_getItem(_record, "buy");
         if(_buy->type==Json_Number)
        {
          int buy=_buy->valueint;
          CCLOG("Buy: %d",buy);
      }
       _record=_record->next;
      }
        cocos2d::extension::Json_dispose(root);

这样一个最简单的json解析就好了

json不在同级的.cpp文件

char* text="{"status":10,"body":{"force":5,"latest":{"ver":"2.0","ver_num":"200"}}}";
    Json*root=Json_create(text);
    Json*_status=Json_getItem(root,"status");
    if(_status->type==Json_Number){
        int status=_status->valueint;
        CCLOG("status : %d",status);
    }
    Json*_body=Json_getItem(root,"body");
    if(_body->type==Json_Object){
        Json*_force=Json_getItem(_body,"force");
        if(_force->type==Json_Number){
            int force=_force->valueint;
            CCLOG("force : %d",force);
        }
        Json*_latest=Json_getItem(_body,"latest");
        if(_latest->type==Json_Object){
            Json*_ver=Json_getItem(_latest,"ver");
            if(_ver->type==Json_String){
                const char*ver=_ver->valuestring;
                CCLOG("ver : %s",ver);
            }
            Json*_ver_num=Json_getItem(_latest,"ver_num");
            if(_ver_num->type==Json_String){
                const char *ver_num=_ver_num->valuestring;
                CCLOG("ver_num : %s",ver_num);
            }
        }
    }
