Using JSON StringOf with Non-String Members

See more JSON Examples

If a JSON member is a boolean, integer, or null, using StringOf will return its string representation. C++

#include <CkJsonObject.h>

void ChilkatSample(void)
    {
    //  Create JSON with members of different data types.
    CkJsonObject json;

    json.UpdateInt("a",123);
    json.UpdateBool("b",true);
    json.UpdateNull("c");

    json.put_EmitCompact(false);
    std::cout << json.emit() << "\r\n";

    //  Resulting JSON:
    //  {
    //    "a": 123,
    //    "b": true,
    //    "c": null
    //  }

    const char *a = json.stringOf("a");
    std::cout << a << "\r\n";

    const char *b = json.stringOf("b");
    std::cout << b << "\r\n";

    const char *c = json.stringOf("c");
    std::cout << c << "\r\n";

    //  Output

    //  123
    //  true
    //  null

    //  If you want to get the integer, boolean, or null value
    //  you need to use the methods matching the data type
    int ival = json.IntOf("a");
    bool bval = json.BoolOf("b");
    bool hasNull = json.IsNullOf("c");
    }
