JsonCPP 使用（VC++ 解析Json)

项目中加载.h 和 lib
测试项目在G:colibriDDMDDM

#include <string>
#include "JsonCppjsonjson.h"
void CControl::readJson()
{
    std::string strValue = "{"name":"json","array":[{"cpp":"jsoncpp"},{"java":"jsoninjava"},{"php":"support"}]}";
    Json::Reader reader;
    Json::Value value;
    if (reader.parse(strValue, value))
    {
        std::string out = value["name"].asString();
        const Json::Value arrayObj = value["array"];
        for (unsigned int i = 0; i < arrayObj.size(); i++)
        {
            if (!arrayObj[i].isMember("cpp"))
                continue;
            out = arrayObj[i]["cpp"].asString();            
        }
    }
}
 
//生成JSON格式数据
void CControl::writeJson()
{
    Json::Value root;
    Json::Value arrayObj;
    Json::Value item;
    item["cpp"] = "jsoncpp";
    item["java"] = "jsoninjava";
    item["php"] = "support";
    arrayObj.append(item);
    root["name"] = "json";
    root["array"] = arrayObj;
    //std::string out = root.toStyledString();  //格式化

    Json::FastWriter writer;
    std::string strWrite = writer.write(root);
    AfxMessageBox(strWrite.c_str());
    int len = strWrite.length();
    m_MesClient.SendClient((char*)strWrite.c_str(), len);
    /*std::ofstream ofs;
    ofs.open("test_write.json");
    ofs << strWrite;
    ofs.close();

    std::cout << out << std::endl;*/
