Duplicate curl -u user:password with Chilkat HTTP

See more HTTP Misc Examples

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"

        // The AddHeader method corresponds to the curl "-H" argument.
        req.addHeader("Accept", "application/json");

        // 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.
        req.addParam("grant_type", "client_credentials");
