C++ CJsonObject 使用时记录

json数据： 

{
	"api":"setDatas",
	"apiVer" : 0,
	"packSn" : 0,
	"operate" : "command",
	"option" : ["none"],
	"param" : {
		"id": 1,
		"datas": [1, 2, 3, 4, 5, 6]
	},
	"endFlg":"api"
}

 接收函数：

CMDFN(setDatas)
{
    int id;
    int datas[256];
    cmd["param"].Get("id",id);
    int len = cmd["param"]["datas"].GetArraySize();
    for(int i=0;i<len;i++) {
//      cmd["param"].Get(i,datas[i]); 错
//      cmd["param"].Get("datas"[i], datas[i]);  错
        cmd["param"]["datas"].Get(i, datas[i]);
    }
    ack.Replace("param",1);
    ack.ReplaceWithNull("option");
    ack.Replace("srxApi",cmd("api"));
    ack.Replace("packSn",cmd("packSn"));
    return 0;
}

{
    vector<int> list = {1, 2, 3, 4};
    CJsonObject data;
	data.AddEmptySubArray("param");
    for(int i = 0; i< list.size(); i++) {
        data["param"].Add(list[i]);
    }
    cout<< list.size()<<data["param"].GetArraySize()<<endl;
    ack.Replace("param",data["param"]);
    ack.ReplaceWithNull("option");
    ack.Replace("srxApi",cmd("srxApi"));
    ack.Replace("packSn",cmd("packSn"));
}

// param 打印 [1, 2, 3, 4];

// --------------------------------------------------

char list[20*1024];
vector<int> arr;
CJsonObject data;
data.AddEmptySubArray("param");
for(int i = 0; i< 20*1024; i++) {
   arr.push_back(list[i]);
}


// --------------------------------------------------

json数据： {"param" : 1}

// 获取
int id;
cmd.Get("param", id);

 CJsonObject data;
    data.AddEmptySubArray("param");
for(int i = 0;i < 2;i++) {
    CJsonObject obj;
         obj.Add("url", "127.0.0.1");

         obj.Add("str", "111");

         data["param"].Add(obj);
}
