(Go) 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.

    http := chilkat.NewHttp()
    req := chilkat.NewHttpRequest()

    // 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.SetLogin("PAYPAL_REST_API_CLIENT_ID")
    http.SetPassword("PAYPAL_REST_API_SECRET")

    // Sends a POST request where the Content-Type is application/x-www-form-urlencoded
    resp := http.PostUrlEncoded("https://api.sandbox.paypal.com/v1/oauth2/token",req)
    if http.LastMethodSuccess() != true {
        fmt.Println(http.LastErrorText())
        http.DisposeHttp()
        req.DisposeHttpRequest()
        return
    }

    if resp.StatusCode() != 200 {
        fmt.Println("Error status code: ", resp.StatusCode())
        fmt.Println(resp.BodyStr())
        resp.DisposeHttpResponse()
        http.DisposeHttp()
        req.DisposeHttpRequest()
        return
    }

    // The JSON response is in the resp BodyStr property
    fmt.Println(resp.BodyStr())
    fmt.Println("-- Success.")

    resp.DisposeHttpResponse()

    http.DisposeHttp()
    req.DisposeHttpRequest()
