HTTP - Verify Server is a Trusted Root CA

See more HTTP Examples

Demonstrates how to only allow connections to an HTTP server having a certificate with a root that is in our list of trusted CA root certificates. Ruby

require 'chilkat'

success = false

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

success = false

#  On my particular system, the root CA cert for this URL is not pre-installed.
#  Note: This may be different for you.
#  Also, this example was written on 29-May-2015.  This URL was valid at the time,
#  but may not be valid at a future date.
url = "https://animals.nationalgeographic.com/animals/invertebrates/starfish/"

http = Chilkat::CkHttp.new()

#  Require that the SSL/TLS server certificate is not expired,
#  and that the certificate signature is valid.
#  This does not ensure that it has a chain of authentication to
#  a trusted root.  To ensure that, the TrustedRoots object (below) is required.
http.put_RequireSslCertVerify(true)

#  Do the HTTPS page fetch (through the SSH tunnel)
html = http.quickGetStr(url)
if (http.get_LastMethodSuccess() != true)
    print http.lastErrorText() + "\n";
    exit
end

print "The HTTP GET was successful." + "\n";

#  Now let's require that HTTP requests to SSL/TLS servers that don't have trusted CA roots
#  should fail.
trustedRoots = Chilkat::CkTrustedRoots.new()

#  Indicate that we will trust any pre-installed certificates on this system.
#  (The meaning of pre-installed certificates depends on the operating system, and in
#  some environments there is no such thing as pre-installed certificates.  See the reference
#  documentation for the TrustedRoots class.)
trustedRoots.put_TrustSystemCaRoots(true)

#  Activate the trusted roots globally for all Chilkat objects.
#  This call really shouldn't fail, so we're not checking the return value.
success = trustedRoots.Activate()

#  Given that our previous HTTP GET likely kept the connection open,
#  make sure that all HTTP connections are closed before re-trying.
#  Otherwise, we'll simply be re-using the pre-existing connection.
success = http.CloseAllConnections()

#  Now let's try fetching the URL again.  It should fail this time because
#  there is a requirement that the SSL/TLS server certificate must have a trusted root,
#  and the trusted root for this URL is not installed on my system (but may be different for you..)
html = http.quickGetStr(url)
if (http.get_LastMethodSuccess() != true)
    print http.lastErrorText() + "\n";
    print "Good, the HTTP request failed as expected." + "\n";
else
    print http.lastErrorText() + "\n";
    print "Hmmm... we did not fail as expected?" + "\n";
