I'm trying to use OAuth for Instagram to authenticate, planning to use PHP and cURL. The first step is retrieving a "code" e.g:
fd7d5f6cde6c47e4a86ba28b22ac4583
I've worked with the Twitter API before and it works in a similar way. I exchange the code for an access_token and then I can authenticate.
The issue is that the way to authenticate is to hit a button on a window that says "I give permission". Here is that window:
My question : is there a way to do this without requiring hitting this URL?
For example, is there a way for me to automate this process using my script? When I worked with Twitter, I was able to use cURL to go to this link and pass the authentication, to then retrieve this code.
This is part of a project that will only be used by me essentially to retrieve my own recent instagrams. I don't want visitors to my site to be presented with having to hit "authorise" every time they turn up.
At the moment I'm simply doing this, is there anything I can add to the URL to automatically authorise?
$auth_request_url = 'https://api.instagram.com/oauth/authorize/?client_id='.$client_id.'&redirect_uri='.$redirect_url .'&response_type=code';
/* Send user to authorisation */
header("Location: ".$auth_request_url);
Below is an example of the code that works but only once:
$url = "https://api.instagram.com/oauth/access_token";
$access_token_parameters = array(
'client_id' => $client_id,
'client_secret' => $client_secret,
'grant_type' => 'authorization_code',
'redirect_uri' => $redirect_url,
'code' => $code
);
$curl = curl_init($url); // we init curl by passing the url
curl_setopt($curl,CURLOPT_POST,true); // to send a POST request
curl_setopt($curl,CURLOPT_POSTFIELDS,$access_token_parameters); // indicate the data to send
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); // to return the transfer as a string of the return value of curl_exec() instead of outputting it out directly.
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); // to stop cURL from verifying the peer's certificate.
$result = curl_exec($curl); // to perform the curl session
curl_close($curl); // to close the curl session
$arr = json_decode($result,true);
I got the $code from the end of the URL manually. But it expires after one use. So I need to work out how to run and retrieve the $code each time I want to execute the script.
