I'm wondering how to use the emotion API from microsoft: https://dev.projectoxford.ai/docs/services/5639d931ca73072154c1ce89/operations/563b31ea778daf121cc3a5fa
I've installed the HTTP_Request2 package with pear on my Ubuntu 14.04.3 server
When I use this code, I get a blank page.
<?php
// This sample uses the Apache HTTP client from HTTP Components (http://hc.apache.org/httpcomponents-client-ga/)
require_once 'HTTP/Request2.php';
$request = new Http_Request2('https://api.projectoxford.ai/emotion/v1.0/recognize');
$url = $request->getUrl();
$headers = array(
// Request headers
'Content-Type' => 'application/json',
'Ocp-Apim-Subscription-Key' => 'XXXXX'
);
$request->setHeader($headers);
$parameters = array(
// Request parameters
);
$url->setQueryVariables($parameters);
$request->setMethod(HTTP_Request2::METHOD_POST);
// Request body
$request->setBody('{"url": "http://images.wisegeek.com/triangular-face.jpg"}');
try
{
$response = $request->send();
echo $response->getBody();
}
catch (HttpException $ex)
{
echo $ex;
}
?>
I've looked through the error logs and found this error:
