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"

.NET Core C#

bool success = false;

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

Chilkat.Http http = new Chilkat.Http();
Chilkat.HttpRequest req = new Chilkat.HttpRequest();

// 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.Login = "PAYPAL_REST_API_CLIENT_ID";
http.Password = "PAYPAL_REST_API_SECRET";

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

Chilkat.HttpResponse resp = new Chilkat.HttpResponse();
success = http.HttpReq("https://api.sandbox.paypal.com/v1/oauth2/token",req,resp);
if (success == false) {
    Debug.WriteLine(http.LastErrorText);
    return;
}

if (resp.StatusCode != 200) {
    Debug.WriteLine("Error status code: " + Convert.ToString(resp.StatusCode));
    Debug.WriteLine(resp.BodyStr);
    return;
}

// The JSON response is in the resp BodyStr property
Debug.WriteLine(resp.BodyStr);
Debug.WriteLine("-- Success.");
