(Unicode C++) JSON: Array of ObjectsHere we have a JSON object that contains an array, where each element in the array is a JSON object. This example demonstrates how to access the objects contained within an array. { "employees":[ {"firstName":"John", "lastName":"Doe"}, {"firstName":"Anna", "lastName":"Smith"}, {"firstName":"Peter","lastName":"Jones"} ] }
#include <CkJsonObjectW.h> #include <CkJsonArrayW.h> void ChilkatSample(void) { CkJsonObjectW json; // This is the above JSON with whitespace chars removed (SPACE, TAB, CR, and LF chars). // The presence of whitespace chars for pretty-printing makes no difference to the Load // method. const wchar_t *jsonStr = L"{\"employees\":[{\"firstName\":\"John\", \"lastName\":\"Doe\"},{\"firstName\":\"Anna\", \"lastName\":\"Smith\"},{\"firstName\":\"Peter\",\"lastName\":\"Jones\"}]}"; bool success = json.Load(jsonStr); if (success != true) { wprintf(L"%s\n",json.lastErrorText()); return; } // Get the "employees" array. CkJsonArrayW *employees = json.ArrayOf(L"employees"); if (json.get_LastMethodSuccess() == false) { wprintf(L"employees member not found.\n"); return; } // Iterate over each employee, getting the JSON object at each index. int numEmployees = employees->get_Size(); int i = 0; while (i < numEmployees) { CkJsonObjectW *empObj = employees->ObjectAt(i); wprintf(L"employee[%d] = %s %s\n",i,empObj->stringOf(L"firstName"),empObj->stringOf(L"lastName")); delete empObj; i = i + 1; } delete employees; } |
