Version	58bb3bca346e2c709f5aa474c75a9bca6d91ad9a

Actual Behavior

Throws error at HappyR\LinkedIn\LinkedIn->get('v1/people/~:(firstName,lastName)');

Expected Behavior

Pass the access token and fetch the data.

Steps to Reproduce

Created an autoload.php as following inside /src and called the files as I'm doing it from WordPress and didn't use Composer.

<?php
require_once __DIR__.'/Exception/LinkedInException.php';
require_once __DIR__.'/Exception/InvalidArgumentException.php';
require_once __DIR__.'/Exception/LinkedInTransferException.php';
require_once __DIR__.'/Exception/LoginError.php';

require_once __DIR__.'/Http/CurrentUrlGeneratorInterface.php';
require_once __DIR__.'/Http/GlobalVariableGetter.php';
require_once __DIR__.'/Http/LinkedInUrlGeneratorInterface.php';
require_once __DIR__.'/Http/RequestManagerInterface.php';
require_once __DIR__.'/Http/RequestManager.php';
require_once __DIR__.'/Http/ResponseConverter.php';
require_once __DIR__.'/Http/UrlGeneratorInterface.php';
require_once __DIR__.'/Http/UrlGenerator.php';

require_once __DIR__.'/Storage/DataStorageInterface.php';
require_once __DIR__.'/Storage/BaseDataStorage.php';
require_once __DIR__.'/Storage/IlluminateSessionStorage.php';
require_once __DIR__.'/Storage/SessionStorage.php';

require_once __DIR__.'/AccessToken.php';
require_once __DIR__.'/AuthenticatorInterface.php';
require_once __DIR__.'/Authenticator.php';
require_once __DIR__.'/LinkedInInterface.php';
require_once __DIR__.'/LinkedIn.php';
?>

Then called:

require_once __DIR__.'/LinkedIn/autoload.php';

$linkedIn = new HappyR\LinkedIn\LinkedIn('User_ID', 'User_secret);
$linkedInUrl = $linkedIn->getLoginUrl(array( 'redirect_uri' => 'http://teachfinder.com/log-in?role=teacher' ));
if ( isset( $_GET['code'] ) ) {
    $user=$linkedIn->get('v1/people/~:(firstName,lastName)');
    var_dump($user);
}

Possible Solutions

I was trying to find out \Http\Message\MessageFactory including this could possibly solve the problem.

Thank you for a detailed issue. It really helps me debugging this.

You see this issue because you do not use Composer. To solve the issue, download composer and run:

composer require php-http/curl-client guzzlehttp/psr7 php-http/message happyr/linkedin-api-client

Then you can use composer's autoload.

require_once "vendor/autoload.php";

$linkedIn=new Happyr\LinkedIn\LinkedIn('client_id', 'client_secret');

Hey Nyholm,

I'm also having the same problem stated as above but in my case, I can't access the user profile as it Throws error at HappyR\LinkedIn\LinkedIn->get('v1/people/~:(firstName,lastName)');

I'm using composer and your given composer.json file from the GitHub and when I hit this command "composer install" on cmd it gives an exception as

[RuntimeException] Failed to clone https://github.com/php-http/discovery.git, git was not found,

[Nyholm]

As your Exception message says:

Failed to clone https://github.com/php-http/discovery.git, git was not found,

It seams like you need to install git. Please refer to StackOverflow for issues like this. It is not an issue with this library.
