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;}

加载JSON文件

     //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;
 }

保存修改后的JSON结构

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 = ; 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 = ; 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 = ; i < Objson["WindDirectLine"]["coordinates"][num]["mWindDirectBaseLine"].GetArraySize(); i++)
     {
         cout << "mWindDirectBaseLine" << i << ":" << Objson["WindDirectLine"]["coordinates"][num]["mWindDirectBaseLine"][i]("p") << endl;
     }
     cout << "---------------" << endl;
 }

修改mWindDirectBaseLine节点

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 = ; i < Objson["WindDirectLine"]["coordinates"][num]["mWindDirectBars"].GetArraySize(); i++)
     {
         Objson["WindDirectLine"]["coordinates"][num]["mWindDirectBars"].Delete(i);
         i--;
     }
     cout << "---------------" << endl;
     CJsonObject je;
     for (int i = ; 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;
 }

修改mWindDirectBars节点

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 = ; 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 = ; 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;
 }

修改HuxianArrays节点

 int iValue;
     std::string strValue;
     neb::CJsonObject oJson("{\"refresh_interval\":60,"
         "\"dynamic_loading\":["

         "],"
         "\"module\":["

         "\"module\":[]"
         "}"
         "]"
         "}");
     std::cout << oJson.ToString() << std::endl;
     std::cout << "-------------------------------------------------------------------" << std::endl;
     std::cout << oJson["dynamic_loading"][]["cmd"][]("class") << std::endl;
     oJson["dynamic_loading"][]["cmd"][].Get("cmd", iValue);
     std::cout << "iValue = " << iValue << std::endl;
     oJson["dynamic_loading"][]["module"][].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 = ; i < count; i++)
     {
         iValues = pArr[i];
         ject.Add("p", iValues);
         ject.Add("s", );
         ject.Add("i", -);
         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;
