C++ Json解析CJsonObject的详细使用

引用头文件：

#include <string>
#include <iostream>
#include <fstream>
#include <cassert>
#include <stdio.h>
#include <io.h>
#include<sstream>
#include <vector>
#include "CJsonObject.hpp"

    using namespace std;
    using namespace neb;
  	CJsonObject Objson;

 

__declspec(dllexport)  void  __stdcall read_JSon(char* path)
{
    ifstream t(path);
    string str((istreambuf_iterator<char>(t)),istreambuf_iterator<char>());
    string strValue;
    Objson= CJsonObject(str);
    cout << "-------------------------------------------------------------------" << std::endl;}

    //保存JSON文件
__declspec(dllexport)  void  __stdcall  write_string_to_file_append(char*  file_string)
{
    /*remove(file_string);*/
    std::ofstream    OsWrite(file_string, std::ofstream::trunc);
    OsWrite << Objson.ToString();
    OsWrite << std::endl;
    OsWrite.close();
    std::cout << "------------------执行完毕------------------------" << std::endl;
}

1.修改如下图数据结构：

__declspec(dllexport)  void  __stdcall FxmWindDirectBaseLine(int num,  int count, char** pArr, int* sArr, int* iArr)
{

    string iValue;
    for (int i = 0; i < Objson["WindDirectLine"]["coordinates"][num]["mWindDirectBaseLine"].GetArraySize(); i++)
    {
        Objson["WindDirectLine"]["coordinates"][num]["mWindDirectBaseLine"].Delete(i);
        i--;
    }
    cout << "---------------" << endl;
    cout << Objson["WindDirectLine"]["coordinates"][num]["mWindDirectBaseLine"].GetArraySize() << endl;
    CJsonObject je;
    for (int i = 0; i < count; i++)
    {
        iValue = pArr[i];
        je.Add("p", iValue);
        je.Add("s", sArr[i]);
        je.Add("i", iArr[i]);
        std::cout << "pArr:" << je.ToString() << std::endl;
        Objson["WindDirectLine"]["coordinates"][num]["mWindDirectBaseLine"].Add(je);
        je.Clear();
    }
    cout <<"---------------" << endl;
    for (int i = 0; i < Objson["WindDirectLine"]["coordinates"][num]["mWindDirectBaseLine"].GetArraySize(); i++)
    {
        cout << "mWindDirectBaseLine" << i << ":" << Objson["WindDirectLine"]["coordinates"][num]["mWindDirectBaseLine"][i]("p") << endl;
    }
    cout << "---------------" << endl;
}

2.修改如下图数据结构：

__declspec(dllexport)  void  __stdcall UpmWindDirectBars(int num,int count, char** fpArr,int* fsArr, int* fiArr, char** hpArr, int* hsArr, int* hiArr)
{
    string iValue;
    for (int i = 0; i < Objson["WindDirectLine"]["coordinates"][num]["mWindDirectBars"].GetArraySize(); i++)
    {
        Objson["WindDirectLine"]["coordinates"][num]["mWindDirectBars"].Delete(i);
        i--;
    }
    cout << "---------------" << endl;
    CJsonObject je;
    for (int i = 0; i < count; i++)
    {
        iValue = fpArr[i];
        je.AddEmptySubObject("f");
        je["f"].Add("p", iValue);
        je["f"].Add("s", fsArr[i]);
        je["f"].Add("i", fiArr[i]);
        iValue = hpArr[i];
        je.AddEmptySubObject("h");
        je["h"].Add("p", iValue);
        je["h"].Add("s", hsArr[i]);
        je["h"].Add("i", hiArr[i]);
        std::cout << "pArr:" << je.ToString() << std::endl;
        Objson["WindDirectLine"]["coordinates"][num]["mWindDirectBars"].Add(je);
        je.Clear();
    }
    cout << "---------------" << endl;
}

3.修改如下图数据结构：

__declspec(dllexport)  void  UpHuxianArrays( int count, double* fpArr, double* fsArr, double* fiArr)
{
    std::cout << "-------------------------------------------------------------------" << std::endl;


    for (int i = 0; i <Objson["resultWindSpeedGrid"]["HuxianArrays"].GetArraySize(); i++)
    {
        Objson["resultWindSpeedGrid"]["HuxianArrays"].Delete(i);
        i--;
    }
    cout << "Count:" << Objson["resultWindSpeedGrid"]["HuxianArrays"].GetArraySize() << endl;
    cout << "---------------" << endl;
    CJsonObject je;
    for (int i = 0; i < count; i++)
    {
        je.AddEmptySubArray("Params");
        je["Params"].Add(fpArr[i]);
        je["Params"].Add(fsArr[i]);
        je["Params"].Add(fiArr[i]);
        std::cout << "pArr:" << je.ToString() << std::endl;
        Objson["resultWindSpeedGrid"]["HuxianArrays"].Add(je);
        je.Clear();
    }
    Objson["resultWindSpeedGrid"].Replace("HuxianShu", Objson["resultWindSpeedGrid"]["HuxianArrays"].GetArraySize());
    cout << "---------------" << endl;
}

官方案例：

int iValue;
    std::string strValue;
    neb::CJsonObject oJson("{"refresh_interval":60,"
        ""dynamic_loading":["
        "{"
        ""so_path":"plugins/User.so", "load":false, "version":1,"
        ""cmd":["

        "{"cmd":2003, "class":"neb::CmdUserLogout"}"
        "],"
        ""module":["
        "{"path":"im/user/login", "class":"neb::ModuleLogin"},"
        "{"path":"im/user/logout", "class":"neb::ModuleLogout"}"
        "]"
        "},"
        "{"
        ""so_path":"plugins/ChatMsg.so", "load":false, "version":1,"

        "],"
        ""module":[]"
        "}"
        "]"
        "}");
    std::cout << oJson.ToString() << std::endl;
    std::cout << "-------------------------------------------------------------------" << std::endl;
    std::cout << oJson["dynamic_loading"][0]["cmd"][1]("class") << std::endl;
    oJson["dynamic_loading"][0]["cmd"][0].Get("cmd", iValue);
    std::cout << "iValue = " << iValue << std::endl;
    oJson["dynamic_loading"][0]["module"][0].Get("path", strValue);
    std::cout << "strValue = " << strValue << std::endl;
    std::cout << "-------------------------------------------------------------------" << std::endl;
    oJson.AddEmptySubObject("depend");
    oJson["depend"].Add("nebula", "https://github.com/Bwar/Nebula");
    oJson["depend"].AddEmptySubArray("bootstrap");
    oJson["depend"]["bootstrap"].Add("BEACON");
    oJson["depend"]["bootstrap"].Add("LOGIC");
    oJson["depend"]["bootstrap"].Add("LOGGER");
    oJson["depend"]["bootstrap"].Add("INTERFACE");
    oJson["depend"]["bootstrap"].Add("ACCESS");
    oJson["depend"].AddEmptySubArray("boot");
    CJsonObject ject;
    string iValues;
    for (int i = 0; i < count; i++)
    {
        iValues = pArr[i];
        ject.Add("p", iValues);
        ject.Add("s", 0);
        ject.Add("i", -1);
        std::cout << "pArr:" << ject.ToString() << std::endl;
        oJson["depend"]["boot"].Add(ject);
        ject.Clear();
    }
    std::cout << oJson.ToString() << std::endl;
    std::cout << "-------------------------------------------------------------------" << std::endl;
    std::cout << oJson.ToFormattedString() << std::endl;
