PHP Question

POST mime type using curl

So I'm attempting to use an api called Sky Biometry, which is used for face detection and facial recognition. The api either accepts a url or a post as a MIME type. In this case I would like to directly post the picture to the api, here is what the documentation says:

"Note: in case where you want to POST images instead of specifying urls, request to the method must be formed as a MIME multi-part message sent using POST data. Each argument should be specified as a separate chunk of form data."

I've tried looking around for examples, but have yet to find any, if somebody could help a newbie out it would be greatly appreciated.

Sky Biometry Documentation


Multipart messages are actually standard POST enctype="multipart/form-data" requests. You can generate them quite simply with a simple form, or you can use cURL (as I suspect you are already doing) as follows:

curl_setopt($channel, CURLOPT_POSTFIELDS, array("myfile" => "@/path/to/my/image.png"));

cURL will automatically do the rest (convert your content-type and mime-type it).
