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"

const std = @import("std");
const chilkat = @import("chilkat");

pub fn main(init: std.process.Init) !void {
    const alloc = init.arena.allocator();

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

    const http = try chilkat.Http.init();
    defer http.deinit();
    const req = try chilkat.HttpRequest.init();
    defer req.deinit();

    // 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
    req.setHttpVerb("POST");
    req.setContentType("application/x-www-form-urlencoded");

    const resp = try chilkat.HttpResponse.init();
    defer resp.deinit();
    http.httpReq("https://api.sandbox.paypal.com/v1/oauth2/token", req, resp) catch {
        std.debug.print("{s}\n", .{try http.getLastErrorText(alloc)});
        return;

    if (resp.getStatusCode() != 200) {

        std.debug.print("{s}\n", .{try resp.getBodyStr(alloc)});
