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 middleware
Middleware
Creates middleware layer on Zend Framework 2. Useful when it's necessary to make some work between route and controller dispatch phases.
Installation
With composer
Add this project in your composer.json:
Now tell composer to download Middleware by running the command:
Post installation
Enabling it in your config/application.config.php file.
Configuration
On your config file set your global and local middlewares. For instance:
Usage
Define your middleware classes:
Global scope
Middlewares on global scope will be executed everytime a request is made.
Local scope
Middlewares on local scope will be executed only if the current controller declares a middleware.
P.S: local middlewares are executed after global middlewares.
In this case, my.first.middleware and my.second.middleware will be always executed no matter what route is being called. Whereas my.third.middleware will be executed only when
Application\Controller\IndexController is being called. Thus, if we access Application\Controller\IndexController first, second and third middlewares will be executed.
Advanced usage
Inject Service Locator
It's also possible to access ServiceManager within your middleware classes. It's only necessary to implement ServiceLocatorAwareInterface. For instance:
Abstract Service Factory
