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"

    CkHttp http = new CkHttp();

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

    http.put_Login("PAYPAL_REST_API_CLIENT_ID");
    http.put_Password("PAYPAL_REST_API_SECRET");

    // Sends a POST request where the Content-Type is application/x-www-form-urlencoded
    req.put_HttpVerb("POST");
    req.put_ContentType("application/x-www-form-urlencoded");
