(JavaScript) QuickGetBd Example

The QuickGetBd method is called to send a GET request to download a binary target, such as PDF, zip, image file, etc. into a Chilkat BinData object.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

var http = new CkHttp();
http.KeepResponseBody = true;

var bd = new CkBinData();

// Download the contents of a PDF file into the bd object.
success = http.QuickGetBd("https://www.chilkatsoft.com/hello.pdf",bd);
if (success == false) {
    // This will happen if the response status code was 400 or greater,
    // or if the request could not be sent, or if no response was received.
    // 
    // In other words, success will only be true if bd contains the desired content at the URL (not an error response).
    var statusCode = http.LastStatus;
    console.log("Response status: " + statusCode);

    if (statusCode == 0) {
        // There was an error in communications.  
        console.log(http.LastErrorText);
    }
    else {
        // We received a response status code indicating failure.
        // Examine the response body.
        console.log(http.LastResponseBody);
    }

    return;
}

// Load the downloaded PDF into a Chilkat PDF object.
var pdf = new CkPdf();
success = pdf.LoadBd(bd);
if (success == false) {
    console.log(pdf.LastErrorText);
    return;
}

// ...

console.log("Success.");
