How Laravel Passport works

Laravel Passport explained with an example: learn how to securely authenticate and authorize users with OAuth.

How Laravel Passport works

Laravel Passport is an OAuth2 server and API authentication package for the Laravel framework. It provides a full OAuth2 server implementation for the PHP framework. Passport is built on the League OAuth2 server and provides a full OAuth2 server implementation for the PHP framework. It makes it easy to create authentication endpoints for different types of users, allowing them to authenticate with a single API call.

Passport provides a set of simple APIs that can be used to authenticate users with a single API call. This is done by creating "clients" that represent the different types of users that can authenticate with the API. The client is responsible for sending the user's credentials to the API and receiving an access token in return. The access token is then used to authenticate the user with the API.

To create a client, you must first create an application in Laravel. Once the application has been created, you can then create a client. A client can be any type of user, such as a web application, mobile application, or even a command-line utility. To create a client, you must specify the following information:

• The client's name
• The client's redirect URI (where the user will be redirected after authenticating)
• The client's scope (what type of access the user has to the API)

Once the client has been created, you can then create a token for the user. The token is a secure representation of the user's credentials and can be used to authenticate with the API. To create a token, you must specify the following information:

• The user's credentials (username and password)
• The client's ID
• The scope (what type of access the user has to the API)

Once the token has been created, it can then be used to authenticate with the API. To authenticate with the API, the user must send an HTTP request containing the token in the Authorization header. The API will then validate the token and allow the user to access the protected data.

// Create a new token
$token = $client->requestAccessToken($clientID, $username, $password);

// Authenticate with the API
$http = new GuzzleHttpClient;
$response = $http->request('GET', 'https://api.example.com/protected', [
    'headers' => [
        'Authorization' => 'Bearer ' . $token->access_token,
    ],
]);

// Get the response
$responseBody = json_decode($response->getBody());

// Process the response
if ($responseBody->success) {
    // The request was successful
} else {
    // The request failed
}

Laravel Passport makes it easy to authenticate users with a single API call. It provides a full OAuth2 server implementation for the Laravel framework and makes it easy to create authentication endpoints for different types of users. Passport also provides a set of simple APIs that can be used to authenticate users with a single API call.
