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
