Seriously, did you test your version ?
Did you have a look on the nxs-http.php file after my post ?

Here is the code (for example) :

$args = wp_parse_args( $args );
if ( isset($args['method']) && 'HEAD' == $args['method'] ) $defaults['redirection'] = 0;
$r = wp_parse_args( $args, $defaults ); $r['_redirection'] = $r['redirection'];


Can you explain me how the 2.14.5 version does not require any WordPress functions ?!
wp_parse_args is explained here : https://codex.wordpress.org/Function_Reference/wp_parse_args

There are 6 wp_*() functions in nxs-http.php, which is required by postToGooglePlus.php
(line 11 : require_once “nxs-http.php”; )

Plz, provide a version without wp_*() functions in https://www.nextscripts.com/mypage/?download-api link.

Thanks
