(Visual FoxPro) 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"

Note: This example requires Chilkat v11.0.0 or greater.

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

loHttp = CreateObject('Chilkat.Http')
loReq = CreateObject('Chilkat.HttpRequest')

* The AddHeader method corresponds to the curl "-H" argument.
loReq.AddHeader("Accept","application/json")
loReq.AddHeader("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.
loReq.AddParam("grant_type","client_credentials")

loHttp.Login = "PAYPAL_REST_API_CLIENT_ID"
loHttp.Password = "PAYPAL_REST_API_SECRET"

* Sends a POST request where the Content-Type is application/x-www-form-urlencoded
loReq.HttpVerb = "POST"
loReq.ContentType = "application/x-www-form-urlencoded"

loResp = CreateObject('Chilkat.HttpResponse')
lnSuccess = loHttp.HttpReq("https://api.sandbox.paypal.com/v1/oauth2/token",loReq,loResp)
IF (lnSuccess = 0) THEN
    ? loHttp.LastErrorText
