[DISCONTINUED] Linkedin API integration for Laravel and Lumen 5

Linkedin API integration for Laravel Framework

⚠️ DISCONTINUED AND MIGRATED 🚧

This project is discontinued. I will not offer more support and bugfixes here. For the newer changes, support and improvements please refer to artesaos/laravel-linkedin

This package is a wrapper for Happyr/LinkedIn-API-client. You can view the basic intructions here. Don't forget to consult the oficial LinkedIn API site.

I encourage users to test the branch psr-7 , which is being adopted the psr-7 structure and the independence of an specific http-client. Once the dependencies are stable I will be merge. Please report any bugs or problems.

If you need install on Lumen, go to Lumen section

Installation on Laravel

Install with composer

composer require mauri870/laravel-linkedin

Add service Provider

Mauri870\LinkedIn\LinkedinServiceProvider::class,

Facade

'LinkedIn'  => \Mauri870\LinkedIn\Facades\LinkedIn::class,

Publish config file

php artisan vendor:publish --provider="Mauri870\LinkedIn\LinkedinServiceProvider"

Installation on Lumen

Install with composer

composer require mauri870/laravel-linkedin

Add Service Provider, facade and config parameters to the bootstrap/app.php file

$app->register(\Mauri870\LinkedIn\LinkedinServiceProvider::class);
class_alias(\Mauri870\LinkedIn\Facades\LinkedIn::class,'LinkedIn');

config(['linkedin' => [
        'api_key' => env('LINKEDIN_KEY','yourapikey'),
        'api_secret' => env('LINKEDIN_SECRET','yourapisecret')
]]);

Usage

In order to use this API client (or any other LinkedIn clients) you have to register your app with LinkedIn to receive an API key. Once you've registered your LinkedIn app, you will be provided with an API Key and Secret Key, please fill this values on linkedin.php config file.

####Basic Usage The unique difference in this package is the LinkedIn facade. Instead of this:

$linkedIn=new Happyr\LinkedIn\LinkedIn('app_id', 'app_secret');
$linkedin->foo();

you can simple call the facade for anyone method, like this:

LinkedIn::foo();

The service container automatically return an instance of LinkedIn class ready to use

LinkedIn login

This example below is showing how to login with LinkedIn using LinkedIn facade.

if (LinkedIn::isAuthenticated()) {
     //we know that the user is authenticated now. Start query the API
     $user=LinkedIn::get('v1/people/~:(firstName,lastName)');
     echo  "Welcome ".$user['firstName'];
     exit();
}elseif (LinkedIn::hasError()) {
     echo  "User canceled the login.";
     exit();
}

//if not authenticated
$url = LinkedIn::getLoginUrl();
echo "<a href='$url'>Login with LinkedIn</a>";
exit();

Get basic profile info

You can retrive information using the get() method, like this:

LinkedIn::get('v1/people/~:(firstName,num-connections,picture-url)');

This query return an array of information. You can view all the REST api's methods in REST API Console

How to post on LinkedIn wall

The example below shows how you can post on a users wall. The access token is fetched from the database.

LinkedIn::setAccessToken('access_token_from_db');

$options = ['json'=>
     [
        'comment' => 'Im testing Happyr LinkedIn client with Laravel Framework! https://github.com/mauri870/laravel-linkedin',
        'visibility' => [
               'code' => 'anyone'
        ]
     ]
];

$result = LinkedIn::post('v1/people/~/shares', $options);

You may of course do the same in xml. Use the following options array.

$options = array(
'format' => 'xml',
'body' => '<share>
 <comment>Im testing Happyr LinkedIn client! https://github.com/Happyr/LinkedIn-API-client</comment>
 <visibility>
   <code>anyone</code>
 </visibility>
</share>');

Configuration

The api options

The third parameter of LinkedIn::api is an array with options. Below is a table of array keys that you may use.

Option name	Description
body	The body of a HTTP request. Put your xml string here.
format	Set this to 'json', 'xml' or 'simple_xml' to override the default value.
headers	This is HTTP headers to the request
json	This is an array with json data that will be encoded to a json string. Using this option you do need to specify a format.
response_data_type	To override the response format for one request
query	This is an array with query parameters

Changing request format

The default format when communicating with LinkedIn API is json. You can let the API do json_encode for you. The following code shows you how.

$body = array(
    'comment' => 'Im testing Happyr LinkedIn client! https://github.com/Happyr/LinkedIn-API-client',
    'visibility' => array('code' => 'anyone')
);

LinkedIn::post('v1/people/~/shares', array('json'=>$body));
LinkedIn::post('v1/people/~/shares', array('body'=>json_encode($body)));

When using array('json'=>$body) as option the format will always be json. You can change the request format in three ways.

// By setter
LinkedIn::setFormat('xml');

// Set format for just one request
LinkedIn::post('v1/people/~/shares', array('format'=>'xml', 'body'=>$body));

Understanding response data type

The data type returned from LinkedIn::api can be configured. You may use the LinkedIn::setResponseDataType or as an option for LinkedIn::api

// By setter
LinkedIn::setResponseDataType('simple_xml');

// Set format for just one request
LinkedIn::get('v1/people/~:(firstName,lastName)', array('response_data_type'=>'psr7'));

Below is a table that specifies what the possible return data types are when you call LinkedIn::api.

Type	Description
array	An assosiative array. This can only be used with the json format.
simple_xml	A SimpleXMLElement. See PHP manual. This can only be used with the xml format.
psr7	A PSR7 response.
stream	A file stream.
string	A plain old string.

Using different scopes

If you want to define special scopes when you authenticate the user you should specify them when you are generating the login url. If you don't specify scopes LinkedIn will use the default scopes that you have configured for the app.

$scope = 'r_fullprofile,r_emailaddress,w_share';
//or 
$scope = array('rw_groups', 'r_contactinfo', 'r_fullprofile', 'w_messages');

$url = LinkedIn::getLoginUrl(array('scope'=>$scope));
return "<a href='$url'>Login with LinkedIn</a>";
