(PHP ActiveX) Xero API through an SOCKS ProxyThis example demonstrates connecting through a SOCKS proxy w/ 2-legged OAuth for a Xero private application. This example requires Chilkat v9.5.0.64 or later
<?php // This example requires Chilkat v9.5.0.64 or later // This sample code would typically be placed in a subroutine or function // where the rest object is passed by reference. // It does the OAuth1 setup and makes the initial connection. $rest = new COM("Chilkat_9_5_0.Rest"); // Connect to the Xero server through an HTTP proxy, and then tell the REST object // to use the socket connection. $socket = new COM("Chilkat_9_5_0.Socket"); // Set the SOCKS proxy domain or IP address, port, and SOCKS version number (4 or 5) $socket->SocksHostname = '192.168.1.100'; $socket->SocksPort = 1080; $socket->SocksVersion = 5; // Other properties exist for specifying a SOCKS proxy login and password, // but these are not used in this example. // Connect through the SOCKS proxy.. $bTls = 1; $port = 443; $maxWaitMs = 5000; $success = $socket->Connect('api.xero.com',$port,$bTls,$maxWaitMs); if ($success != 1) { print 'Connect Failure Error Code: ' . $socket->ConnectFailReason .
