PHP - 检索访问令牌 - 禁用隐式OAuth

Question

I'm using the Instagram Api. To retrieve the access token, I use the method with the parameter 'code'. From this code parameter, I can build a url which will returns me the access token.

Example :

https://instagram.com/oauth/authorize/?client_id=CODE_ID&redirect_uri=my-redirect-url&response_type=code

When I reach this URL through my web browser, after a redirection by Instagram, it returns to a web service I created. Then, my access token is stored.

How can I automatize this in PHP?

This example doesn't work:

exec('curl https://instagram.com/oauth/authorize/?client_id=CODE_ID&redirect_uri=my-redirect-url&response_type=code');

How can I handle the redirection by Instagram?

Thanks in advance.

Answer 1

There's no way to automate this since explicit user authentication is required before an authorization code is generated. So you'll have to redirect using PHP:

header('Location: https://instagram.com/oauth/authorize/?client_id=CODE_ID&redirect_uri=my-redirect-url&response_type=code');

have the user authenticate in the browser to Instagram and then grab the code that is delivered to the redirect_uri by Instagram.
