Node.js

HTTP HEAD Request

See more HTTP Examples

Sends an HTTP HEAD request and gets the response.

Note: The response to an HTTP HEAD request is always just the response header. The reponse body is always 0 length (thus the reason it's called a "HEAD" request..)

function chilkatExample() {

    var success = false;

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

    var http = new chilkat.Http();

    // If the URL uses "https://", then the connection will be TLS.
    // Otherwise it will be TCP.

    // A failure is when we don't get any response.  It could be a timeout, an inability to connect, etc.
    // For example, a "404 Not Found" response is still a response, and thus deemed success in terms of the API..

    var resp = new chilkat.HttpResponse();
    success = http.HttpNoBody("HEAD","https://example-code.com/",resp);
    if (success == false) {
        console.log(http.LastErrorText);
        return;
    }

    // Examine the response.
    console.log("Status Code = " + resp.StatusCode);
    console.log("Status Line = " + resp.StatusLine);
