C++ Json解析CJsonObject的詳細使用

引用頭文件：

#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;

 

1 __declspec(dllexport)  void  __stdcall read_JSon(char* path) 2 { 3  ifstream t(path); 4     string str((istreambuf_iterator<char>(t)),istreambuf_iterator<char>()); 5     string strValue; 6     Objson= CJsonObject(str); 7     cout << "-------------------------------------------------------------------" << std::endl;}

加載JSON文件

 1     //保存JSON文件
 2 __declspec(dllexport)  void  __stdcall  write_string_to_file_append(char* file_string)  3 {  4     /*remove(file_string);*/
 5  std::ofstream OsWrite(file_string, std::ofstream::trunc);  6     OsWrite << Objson.ToString();  7     OsWrite << std::endl;  8  OsWrite.close();  9     std::cout << "------------------執行完畢------------------------" << std::endl; 10 }

保存修改後的JSON結構

1.修改以下圖數據結構：

 1 __declspec(dllexport)  void  __stdcall FxmWindDirectBaseLine(int num,  int count, char** pArr, int* sArr, int* iArr)  2 {  3 
 4     string iValue;  5     for (int i = 0; i < Objson["WindDirectLine"]["coordinates"][num]["mWindDirectBaseLine"].GetArraySize(); i++)  6  {  7         Objson["WindDirectLine"]["coordinates"][num]["mWindDirectBaseLine"].Delete(i);  8         i--;  9  } 10     cout << "---------------" << endl; 11     cout << Objson["WindDirectLine"]["coordinates"][num]["mWindDirectBaseLine"].GetArraySize() << endl; 12  CJsonObject je; 13     for (int i = 0; i < count; i++) 14  { 15         iValue = pArr[i]; 16         je.Add("p", iValue); 17         je.Add("s", sArr[i]); 18         je.Add("i", iArr[i]); 19         std::cout << "pArr:" << je.ToString() << std::endl; 20         Objson["WindDirectLine"]["coordinates"][num]["mWindDirectBaseLine"].Add(je); 21  je.Clear(); 22  } 23     cout <<"---------------" << endl; 24     for (int i = 0; i < Objson["WindDirectLine"]["coordinates"][num]["mWindDirectBaseLine"].GetArraySize(); i++) 25  { 26         cout << "mWindDirectBaseLine" << i << ":" << Objson["WindDirectLine"]["coordinates"][num]["mWindDirectBaseLine"][i]("p") << endl; 27  } 28     cout << "---------------" << endl; 29 }

修改mWindDirectBaseLine節點

2.修改以下圖數據結構：

 1 __declspec(dllexport)  void  __stdcall UpmWindDirectBars(int num,int count, char** fpArr,int* fsArr, int* fiArr, char** hpArr, int* hsArr, int* hiArr)  2 {  3     string iValue;  4     for (int i = 0; i < Objson["WindDirectLine"]["coordinates"][num]["mWindDirectBars"].GetArraySize(); i++)  5  {  6         Objson["WindDirectLine"]["coordinates"][num]["mWindDirectBars"].Delete(i);  7         i--;  8  }  9     cout << "---------------" << endl; 10  CJsonObject je; 11     for (int i = 0; i < count; i++) 12  { 13         iValue = fpArr[i]; 14         je.AddEmptySubObject("f"); 15         je["f"].Add("p", iValue); 16         je["f"].Add("s", fsArr[i]); 17         je["f"].Add("i", fiArr[i]); 18         iValue = hpArr[i]; 19         je.AddEmptySubObject("h"); 20         je["h"].Add("p", iValue); 21         je["h"].Add("s", hsArr[i]); 22         je["h"].Add("i", hiArr[i]); 23         std::cout << "pArr:" << je.ToString() << std::endl; 24         Objson["WindDirectLine"]["coordinates"][num]["mWindDirectBars"].Add(je); 25  je.Clear(); 26  } 27     cout << "---------------" << endl; 28 }

修改mWindDirectBars節點

3.修改以下圖數據結構：

 1 __declspec(dllexport)  void  UpHuxianArrays( int count, double* fpArr, double* fsArr, double* fiArr)  2 {  3     std::cout << "-------------------------------------------------------------------" << std::endl;  4 
 5 
 6     for (int i = 0; i <Objson["resultWindSpeedGrid"]["HuxianArrays"].GetArraySize(); i++)  7  {  8         Objson["resultWindSpeedGrid"]["HuxianArrays"].Delete(i);  9         i--; 10  } 11     cout << "Count:" << Objson["resultWindSpeedGrid"]["HuxianArrays"].GetArraySize() << endl; 12     cout << "---------------" << endl; 13  CJsonObject je; 14     for (int i = 0; i < count; i++) 15  { 16         je.AddEmptySubArray("Params"); 17         je["Params"].Add(fpArr[i]); 18         je["Params"].Add(fsArr[i]); 19         je["Params"].Add(fiArr[i]); 20         std::cout << "pArr:" << je.ToString() << std::endl; 21         Objson["resultWindSpeedGrid"]["HuxianArrays"].Add(je); 22  je.Clear(); 23  } 24     Objson["resultWindSpeedGrid"].Replace("HuxianShu", Objson["resultWindSpeedGrid"]["HuxianArrays"].GetArraySize()); 25     cout << "---------------" << endl; 26 }

修改HuxianArrays節點
