Configure AWS Signature Authentication for REST

See more REST Examples

Demonstrates Rest.SetAuthAws, which associates an AuthAws provider so Chilkat signs each request using AWS Signature Version 4. The provider supplies the access key, secret key, region, and service name.

load ./chilkat.dll

set success 0

set rest [new_CkRest]

set bTls 1
set bAutoReconnect 1
set success [CkRest_Connect $rest "example.com" 443 $bTls $bAutoReconnect]
if {$success == 0} then {
    puts [CkRest_lastErrorText $rest]
    delete_CkRest $rest
    exit
}

#  Configure AWS Signature Version 4 request signing.  Provide the access key, secret key, region,
#  and service name.
set authAws [new_CkAuthAws]

#  Normally you would not hard-code secrets in source.  You should instead obtain them from an
#  interactive prompt, environment variable, or a secrets vault.
