pigsfoot Posted June 2, 2015 Share Posted June 2, 2015 Hi, Firstly, Apologies if I'm asking to much of the forum.I have been sent an example file to create an API link to a back-end system we use, unfortunately I have no experience with PHP and the file isn't working. I have asked the people who gave me the file if they can help and i just get a response of "We don't support it"When i run the script i get the following error message, i have removed the domain name from the error message as the actual file contains keys that can not be changed. ResponseString:Fatal error: Uncaught exception 'Exception' with message 'Unexpected output: ' in /homepages/0/d105761280/htdocs/***/APi.php:121 Stack trace: #0 /homepages/0/d105761280/htdocs/***/APi.php(112): PurpleAPIConnection->parseResponse(false) #1 /homepages/0/d105761280/htdocs/***/APi.php(16): PurpleAPIConnection->getEndpoint('/ping') #2 {main} thrown in /homepages/0/d105761280/htdocs/***/APi.php on line 121 The code is below, i have removed the public and secret key as they are specific to this connection and can not be changed... sorry.Just for info... the server the script is being run on is using PHO 5.5... not sure if that matters or not but i did read on another forum that some commands may be specif to the version of PHP in use.Any help on this would be very much appreciated as i have no idea where to even start.Thanks.. <?php // Enter your details here; find the Key and Secret from the excel CSV Spread sheet. //If this has not been provided to you, you will need to request this from support@purplewifi.net $public_key = 'xxx'; $private_key = 'xxx'; $domain = 'http://purpleportal.net/'; // create new api instance $api = new PurpleAPIConnection($public_key, $private_key, $domain); // run a few API calls: // first: test api; this tests the APi Function to see if it recalls back correctly. $endpoint = $api->getEndpoint('/ping'); print_r($endpoint['data']); // second: get venues; get a list of venues beneath that customer record group; APi Key & Secret. $response = $api->getEndpoint('/venues'); if ($response['data']) { print_r($response['data']['venues']); // third: grab a random venue $random = round(rand(0, count($response['data']['venues']))); $venue_id = $response['data']['venues'][$random]['id']; if ($venue_id) { // fourth: get visitors from august 1st onwards for that venue $response = $api->getEndpoint("/venue/$venue_id/visitors?from=20140801"); if ($response) { print_r($response); } } } else { echo "No venues found!\n"; print_r($response); } // portal api class class PurpleAPIConnection { protected $public_key; protected $private_key; protected $domain; protected $protocol; protected $contenttype; public function __construct($public_key, $private_key, $domain, $protocol = 'https') { $this->public_key = $public_key; $this->private_key = $private_key; $this->domain = $domain; $this->protocol = $protocol; $this->contenttype = 'application/json'; $this->ensureCurl(); } private function ensureCurl() { if (!function_exists('curl_init')) { throw new \Exception("This requires PHP's CURL library"); } } public function getEndpoint($url, $get_data = array(), $post_data = array()) { $url = '/api/company/v1' . $url; $date = new DateTime('now', new DateTimeZone('UTC')); $date = $date->format('D, d M Y H:i:s T'); $post_string = is_array($post_data) ? http_build_query($post_data) : ''; $query_string = is_array($get_data) ? http_build_query($get_data) : ''; if ($query_string) { $url .= '?' . $query_string; } $token_string = $this->contenttype .

pigsfoot Posted June 2, 2015 Author Share Posted June 2, 2015 Not sure how to mark as resolved... Anyway... fixed it... turns out it was the original URL variable... it had http:// where it should of just been the domain.. the rest of the script enters the http:// part Quote Link to comment https://forums.phpfreaks.com/topic/296601-script-error-code-not-sure-where-to-start/#findComment-1513047 Share on other sites More sharing options...
