FAQ
Example:
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 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 auth-gate
Auth Gate
A framework-agnostic library for defining abilities and enforcing authorisation checks against an authenticated user.
Introduction
This library lets you register named ability callbacks and evaluate them against the authenticated user who is performing the action. It supports global before callbacks for overrides, checks for single or multiple abilities, and an explicit authorisation flow that throws an unauthorised exception when checks fail. Undefined abilities and invalid before callback return values are also surfaced through typed exceptions.
Prerequisites
Installation
Getting Started
1. Implement the actor
Any class that represents an authenticated actor must implement the Authenticatable interface. This is the object that will be evaluated against your defined abilities.
2. Create a Gate instance
Instantiate the Gate with the authenticated actor. This instance will be used to define and evaluate abilities.
Usage
The following examples demonstrate the available gate operations using the setup above.
Defining Abilities
Abilities are registered via the define method, which accepts an ability name and a callback that returns a boolean.
Checking Abilities
Use allows and denies to evaluate a single ability, or all and any for multiple abilities.
Authorising Actions
authorize throws an UnauthorizedException if the actor lacks any of the given abilities.
Registering Before Callbacks
Before callbacks run prior to all ability checks. Returning true or false short-circuits the evaluation; returning null (or nothing) defers to the defined ability.
