HTTP Response Inspection

See more HTTP Examples

Demonstrates how to inspect the HTTP response, including the status code, status text, and response headers, for Chilkat methods that don't use an HttpResponse object. C++

#include <CkHttp.h>
#include <CkMime.h>

void ChilkatSample(void)
    {
    CkHttp http;

    //  Returns the contents of the response body.
    const char *jsonText = http.quickGetStr("https://chilkatsoft.com/helloWorld.json");

    //  Examine the response status code.
    std::cout << "response status code: " << http.get_LastStatus() << "\r\n";

    //  Examine the response status text
    std::cout << "response status text: " << http.lastStatusText() << "\r\n";

    //  Examine the full response header.
    std::cout << "response header:" << "\r\n";
    std::cout << http.lastResponseHeader() << "\r\n";
    std::cout << "----" << "\r\n";

    //  Examine the response content-type
    std::cout << "LastContentType = " << http.lastContentType() << "\r\n";

    //  Examine the response last-mod date
    std::cout << "LastModDate = " << http.lastModDate() << "\r\n";

    //  Load the response header into a Chilkat MIME object to access its fields individually.
    CkMime mime;
    mime.LoadMime(http.lastResponseHeader());

    int numHeaders = mime.get_NumHeaderFields();
    int i = 0;
    std::cout << "---- MIME Headers ----" << "\r\n";
    while (i < numHeaders) {
        std::cout << "name:  " << mime.getHeaderFieldName(i) << "\r\n";
        std::cout << "value: " << mime.getHeaderFieldValue(i) << "\r\n";
        i = i + 1;
    }

    std::cout << "----" << "\r\n";

    //  Get a header field value by name:
    std::cout << "ETag: " << mime.getHeaderField("ETag") << "\r\n";

    //  Output:

    //  response status code: 200
    //  response status text: OK
