(Tcl) Duplicate curl -u user:password with Chilkat HTTP

Demonstrates how to duplicate a curl command that uses the -u username:password option. (This assumes HTTP Basic Authentication, and Chilkat requires Basic authentication to be over a TLS connection.)

Duplicates the following curl command:

curl https://api.sandbox.paypal.com/v1/oauth2/token \
  -H "Accept: application/json" \
  -H "Accept-Language: en_US" \
  -u "Client-Id:Secret" \
  -d "grant_type=client_credentials"

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

set http [new_CkHttp]

set req [new_CkHttpRequest]

# The AddHeader method corresponds to the curl "-H" argument.
CkHttpRequest_AddHeader $req "Accept" "application/json"
CkHttpRequest_AddHeader $req "Accept-Language" "en_US"

# The curl "-d" argument specifies the HTTP request body.  In this case,
# we're sending an application/x-www-form-urlencoded request, and therefore
# the body contains the URL-encoded query parameters.
CkHttpRequest_AddParam $req "grant_type" "client_credentials"
