After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Informations about the package laravel-stateless-session

CSRF verification and session persistent through request/response headers.

This is a lightweight package which allow you to manage a session in a stateless communication (REST/API) when the API domain and main web application domain are different.

E.g.

In that case you cannot set cookie for different main domains

See why you cannot set cookie under different domain.

Installation

You can install the package via composer:

Usage

  1. Trigger session, make a GET request to: /api/csrf-header. This will return a header with the session key and an optional header with CSRF token XSRF-TOKEN. The header name could be configured in: stateless.header

  2. Use this header session key/value for every request you want to take care of the session.

  3. If you want to benefit of the CSRF protection of your requests, you should add the follow middlewares to your routes:

You can create a middleware group in your Http\Kernel with these 2 routes as:

Now the server will return 419 (Page expired code).

Unless you send back a request header named: X-CSRF-TOKEN with the value received by the first GET request in the XSRF-TOKEN header.

Done.

Config

The lifetime and other options could be set as before in the session file.

The VerifyHeaderCsrfToken and StartStatelessSession middlewares will inject into headers the session key.

The session key name could be configured in the:

Danger: The key name separators should use - not _ according with this.

You can customize the middleware for the csrf-header route. In some cases you may need some custom cors middleware for example:

Real use case

Let's say you want to allow visitors to submit a newsletter form. You want also to protect your API with CSRF.

You can setup a GoogleRecaptcha for that, but that's so annoying.

Solution:

Vue newsletter page:

api.php

Security

Since the Session Key and X-CSRF-TOKEN could be read by the JavaScript code, that means it's less secure than a usual http-only Cookie. But since we have different domains for the API and WEB, we don't have a way to setup a cookie. You can think of this as of the Bearer token. The security impact is exactly the same.
