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..)

Rust

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

let http = chilkat::Http::new();

// 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..

let resp = chilkat::HttpResponse::new();
if http.http_no_body("HEAD", "https://example-code.com/", &resp).is_err() {
    println!("{}", http.last_error_text());
    return;
}

// Examine the response.
println!("Status Code = {}", resp.status_code());
println!("Status Line = {}", resp.status_line());
println!("Status Text = {}", resp.status_text());
println!("Full Response Header:");
println!("{}", resp.header());
println!("----");
let num_header_fields = resp.num_header_fields();
println!("Num Header Fields: {}", num_header_fields);
for i in 0..num_header_fields {
    println!("{}: {}", resp.get_header_name(i).unwrap_or_default(), resp.get_header_value(i).unwrap_or_default());
