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. Android™

// Important: Don't forget to include the call to System.loadLibrary
// as shown at the bottom of this code sample.

    CkHttp http = new CkHttp();

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

    //  Examine the response status code.
    Log.i(TAG, "response status code: " + String.valueOf(http.get_LastStatus()));

    //  Examine the response status text
    Log.i(TAG, "response status text: " + http.lastStatusText());
