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..)

Ruby

require 'chilkat'

success = false

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

http = Chilkat::CkHttp.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..

resp = Chilkat::CkHttpResponse.new()
success = http.HttpNoBody("HEAD","https://example-code.com/",resp)
if (success == false)
    print http.lastErrorText() + "\n";
    exit
end

# Examine the response.
print "Status Code = " + resp.get_StatusCode().to_s() + "\n";
print "Status Line = " + resp.statusLine() + "\n";
print "Status Text = " + resp.statusText() + "\n";
print "Full Response Header:" + "\n";
print resp.header() + "\n";
print "----" + "\n";
numHeaderFields = resp.get_NumHeaderFields()
print "Num Header Fields: " + numHeaderFields.to_s() + "\n";

for i in 0 .. numHeaderFields - 1
    print resp.getHeaderName(i) + ": " + resp.getHeaderValue(i) + "\n";
