Optionally, install the paragonie/sodium_compat package from composer if your Use composer to manage your dependencies and download PHP-JWT: composer require firebase/php-jwt You can also choose to include the token as a parameter in the request URL or as part of data payload sent from the client if you don't want to deal with HTTP headers.A simple library to encode and decode JSON Web Tokens (JWT) in PHP, conforming to RFC 7519. Note: We assume that the client sends the JWT token inside an HTTP Authorization header in the JWT or Bearer formats. A JWT token is simply a JSON object that has information about the user. Since these important information are now persisted in the client local storage we need to protect it from eyes dropping.Įnter JWTs. In order to solve the issue, the client is responsible for perisiting the state locally and send it to the sever with each request. This means, we can not access the state of a client (such as login state). If you are building a REST API application using PHP, you are not going to use the $_SESSION variable to save data about the client's session. This means that requests from clients should contain all the necessary information required to process the request. The server checks the token and allow or deny access to the request resource. When building REST API, instead of server sessions commonly used in PHP apps we tokens which are sent with HTTP headers from the server to clients where they are persisted (usually using local storage) then attached to every outgoing request originating from the client to the server. JWT stands for JSON Web Token and comprised of user encrypted information that can be used to authenticate users and exchange information between clients and servers. We'll create REST API endpoints for allowing users to login and signup to access protected resources. We'll also see how to get the authorization header in PHP. In this tutorial, we'll learn how to add JWT authentication to our REST API PHP application. ![]()
