Documentation

See the official API documentation for more information.

Installation

Use the package manager composer to install package.

composer require ejlin/line-login-sdk-php

Usage

###Pure PHP version:

$httpClient = new \EJLin\LINELogin\GuzzleHTTPClient();

// Channel Basic Information: https://developers.line.biz/console/channel/<channel id>/basics
$LINELogin = new \EJLin\LINELogin($httpClient, ['clientId' => '<channel id>','clientSecret' => '<channel secret>']);

// Step 3. After login, the LINE will redirect to the URL that you requested with state and code
if(isset($_GET['code']) && isset($_GET['state']))
{
    // TODO: Check the state code same as what you requested
    
    // Request access token from the LINE platform
    $token = $LINELogin->requestToken(
        'https://yourdomain.com', // The url must be the same as requested
        $_GET['code'] // Each code only can request a token once
    );
    
    // Get user profile from the LINE platform
    $userProfile = $LINELogin->getUserProfile($token);
    
    printf("Hello %s !",$userProfile->getDisplayName());
    
    exit;
}

// A unique alphanumeric string used to prevent cross-site request forgery
$state = \EJLin\LINELogin\Helper::randomString(40);

// Step 1. Make authorize url
$authorizeUrl = $LINELogin->makeAuthorizeUrl(
    'https://yourdomain.com', // Callback URL: https://developers.line.biz/console/channel/<channel id>/line-login
    'profile openid email', // Permissions requested from the user: https://developers.line.biz/en/docs/line-login/integrate-line-login/#scopes
    $state
);

// Step 2. Redirect to authorize url
header("Location: $authorizeUrl");
exit;

###Laravel support:

After installed, add LINE_LOGIN_CHANNEL_ID and LINE_LOGIN_CHANNEL_SECRET to .env

LINE_LOGIN_CHANNEL_ID=<channel id>
LINE_LOGIN_CHANNEL_SECRET=<channel secret>

then you can use LINELogin and LINELoginHelper facades like following.

// Step 3.
if(request()->has('code') && request()->has('state'))
{
    $token = \EJLin\Laravel\Facades\LINELogin::requestToken(
            url()->current(),
            request()->input('code'),
        );

    $userProfile = \EJLin\Laravel\Facades\LINELogin::getUserProfile($token);

    return "Hello {$userProfile->getDisplayName()} !";
}

$state = \EJLin\Laravel\Facades\LINELoginHelper::randomString(40);

// Step 1.
$authorizeUrl = \EJLin\Laravel\Facades\LINELogin::makeAuthorizeUrl(
    url()->current(),
    'profile openid email',
    $state
);

// Step 2.
return redirect()->away($authorizeUrl);
