Load JSON Array from HTTP Response Body

Demonstrates how to load the HTTP response body directly into a JsonArray. C

#include <C_CkHttp.h>

void ChilkatSample(void)
    {
    BOOL success;
    HCkHttp http;
    HCkHttpResponse resp;
    HCkJsonArray jarr;

    success = FALSE;

    http = CkHttp_Create();

    resp = CkHttpResponse_Create();
    success = CkHttp_HttpStr(http,"GET","https://www.chilkatsoft.com/exampledata/sampleArray.json","","","",resp);
    if (success == FALSE) {
        printf("%s\n",CkHttp_lastErrorText(http));

    //  A JSON array is JSON that begins with "[" and ends with "]"
    jarr = CkJsonArray_Create();

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

    CkHttpResponse_GetBodyJarr(resp,jarr);

    printf("%s\n",CkJsonArray_emit(jarr));

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


    CkHttp_Dispose(http);
    CkHttpResponse_Dispose(resp);
