使用cURL使用php保护Instagram请求

Question

I've been struggling with this for a while now and still could not find a clear guide to do this.

If I want to make requests to Instagram API using cURL, I do it like this:

<?php

$url = "https://api.instagram.com/v1/users/self/?access_token=MY_TOKEN";

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);

curl_exec($ch);

curl_close($ch);

?>

It works fine, but it's a bit insecure and thats why I'd like to do it with signed request , which uses this sig -parameter.

Now, I can easily create that sig -parameter(signature key) using the code found from here , but how to use that signature with PHP?

I'm totally confused.

The answer is hinted at Instagram's documentation page. Still this is how I did:

• Use the generate signature php function mentioned there to generate $sig .

• Attach it to your endpoint using http_build_query() like this:

   $endpoint = "https://api.instagram.com/v1/users/self/"; $secured_get_fields = array( "access_token" => $access_token, //other get fields as required "sig" => $sig ); $api_url = $endpoint . "?" . http_build_query($secured_get_fields); 

• Call with this $api_url

Hope it helps!
