(Unicode C++) Load JSON Object from HTTP Response Body

Demonstrates how to load the HTTP response body directly into a JSON object.

Note: This example requires Chilkat v9.5.0.89 or greater because it uses the GetBodyJson method. Prior to v9.5.0.89, and application would need to first copy the HTTP response body to a Chilkat StringBuilder object by calling GetBodySb, and then load the JSON object by calling LoadSb.

    // A JSON object is JSON that begins with "{" and ends with "}"
    CkJsonObjectW json;

    // If we wish to transfer (instead of copy) the JSON from the HttpResponse to the JsonObject, then add the keyword "TakeResponseBody" to UncommonOptions
    // This could save memory for extremely large JSON responses.
    resp->put_UncommonOptions(L"TakeResponseBody");

    resp->GetBodyJson(json);

    json.put_EmitCompact(false);
    wprintf(L"%s\n",json.emit());

    // Note: If UncommonOptions contained "TakeResponseBody", then the response BodyStr will now be empty:
    wprintf(L"----\n");
    wprintf(L"%s\n",resp->bodyStr());

    delete resp;
