HTTP request with PHP CURL and getting different result from postman and curl cli

Question

I'm trying to make a GET request using curl in php with the code below.

test.php

$curl = curl_init(); curl_setopt_array($curl, array( CURLOPT_URL => 'https://apiaddress/collection', CURLOPT_RETURNTRANSFER => true, CURLOPT_HTTPHEADER => array( 'Authorization: Bearer 374dad6fdc005a0f17c49aeg77rbifuy48t7205hfhf7he8857c' ), CURLINFO_HEADER_OUT => true )); $response = curl_exec($curl); $err = curl_error($curl); $info = curl_getinfo($curl, CURLINFO_HEADER_OUT); $httpCode = curl_getinfo($curl, CURLINFO_HTTP_CODE); if ($err) { echo "cURL Error #:" . $err; } else { echo "Response code: " . $httpCode . "\nResponse body: \n" . $response . "\n"; } curl_close($curl); echo $info;

This request works in Postman and works using this curl command curl -X GET \ https://apiaddress/collection -H 'Authorization: Bearer 374dad6fdc005a0f17c49aeg77rbifuy48t7205hfhf7he8857c', but when I run php test.php in the cli I get this output. I'm guessing I'm missing a header or sending an incorrect header somewhere?

Response code: 401

Response body:

{"type":"https://apiaddress/errors#error-unauthorized","title":"Unauthorized","detail":"No authorization credentials provided. You must provide an authorization token for this request.","status":401}

GET /collection HTTP/2

Host: apiaddress

Accept: */*

Authorization: Bearer 374dad6fdc005a0f17c49aeg77rbifuy48t7205hfhf7he8857c

I too suspect it's an issue with the headers, why not compare the two? You may need to specify Content-Type in your PHP request. — EternalHour

It turns out that this API requires the User-Agent header and it seems that Postman and the curl cli send those automatically while the php-curl request doesn't. As soon as I added that header and made up a value it started working.

You appear to be running this under localhost, where you'll additionally need the line:

curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);

This tells cURL not to verify your SSL certificate.

Alternatively, if you do indeed have a .pem certificate file, you can use:

curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, TRUE); curl_setopt($curl, CURLOPT_CAINFO, "/path/to/cacert.pem");

I set that flag and it still didn't work. I also hosted the test.php file on an apache server with php and php-curl installed and the same thing happens.
