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"

Lua

local chilkat = require("chilkat")

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

local http = chilkat.Http.new()
local req = chilkat.HttpRequest.new()

-- The AddHeader method corresponds to the curl "-H" argument.
req:add_header("Accept", "application/json")
req:add_header("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:add_param("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.http_verb = "POST"
req.content_type = "application/x-www-form-urlencoded"

local resp = chilkat.HttpResponse.new()
local success = http:http_req("https://api.sandbox.paypal.com/v1/oauth2/token", req, resp)
if not success then
    print(http.last_error_text)
    return
end

if resp.status_code ~= 200 then
    print("Error status code: " .. resp.status_code)
    print(resp.body_str)
    return
end

-- The JSON response is in the resp BodyStr property
print(resp.body_str)
print("-- Success.")
