Cognitive Service Face api use local image - PHP - php

Question

I am trying to upload an local image to the face API by using PHP, I use the sample code to call the api and it is fine when i am using JSON. but it get stuck when change to octet-stream. i use the below code by referencing "https://pear.php.net/manual/en/package.http.http-request2.request.php"
$image = "images/face-021.jpg";
$fp = fopen($image, 'r+');
$request->addUpload('stuff', $fp, 'custom.name', 'application/octet-stream');
and i get the below responds form the api.
stdClass Object
(
[error] => stdClass Object
(
[code] => InvalidImageSize
[message] => Image size is too small or too big.
)
)
Am i missing some step before passing the binary data to the api?
The image size is just 956 KB and the dimensions is 2448 x 2448

Answer 1

The Face API does not support multipart MIME payloads. You should instead send the image directly in the body of the request.
$image = 'images/face-021.jpg';
$fp = fopen($image, 'rb');
$request->setBody($fp);
$request->setHeader('Content-Type', 'application/octet-stream');
$request->setMethod(HTTP_Request2::METHOD_POST);

function microimg() {
//$GLOBALS['telegram']->ssendmessage($GLOBALS['userid'], $urlImage);
$request = new Http_Request2('https://westus.api.cognitive.microsoft.com/face/v1.0/detect');
$url1 = $request->getUrl();
$headers = array(`enter code here`
'Content-Type' => 'application/json',
'Ocp-Apim-Subscription-Key' => 'xxxxxxxxxxxxxxxxxx'
);
$request->setHeader($headers);
$parameters = array(
// Request parameters
'returnFaceId' => 'true',
'returnFaceLandmarks' => 'false',
'returnFaceAttributes' => 'age',
);
$parameters = array();
$url1->setQueryVariables($parameters);
$request->setMethod(HTTP_Request2::METHOD_POST);
//$request->setBody('{"url": "http://miladddddddddddddd.ml/fillter_image/photos/file_93.jpg" }');
$request->setBody('{"url": "'.$GLOBALS['fileurl'].'" }');
$err = $request->setBody;
try {
$response = $request->send();
echo $response->getBody();
$ed = $response->getBody();
$GLOBALS['telegram']->ssendmessage($GLOBALS['userid'],$ed);
$GLOBALS['telegram']->ssendmessage($GLOBALS['userid'], $GLOBALS['fileurl']);
} catch (HttpException $ex) {
echo $ex;
}
}
microimg($urlimg);
