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 alexa-php-sdk
Amazon Alexa SDK for PHP
This package provides a framework-agnostic expressive SDK for developing Alexa skills in PHP based on https://github.com/maxbeckers/amazon-alexa-php.
Disclaimer
This package is no official Amazon Alexa SDK.
Until now this package does not support every operation which might be needed for writing Alexa skills but is a solid foundation. So feel free to PR missing features.
Install
You can install this package via composer:
Usage
Create a skill and handle requests
Use the following code as starting point for your own skill.
First you have to create a Request object from the POST request's data.
Then create a new skill with Alexa::skill($applicationId), passing your application id.
Finally define your request handers and call handle($request) which handles the request and creates a response.
Middlewares
All requests are piped through several middlewares before the request handler is invoked.
Remember to return $next($request, $response) to invoke the next middleware in the chain.
If you return a $response from a middleware no other handlers are invoked and $response is returned immediately.
Automatically attached middlewares
When creating a skill with Alexa::skill($applicationId) we automatically attach the following two middlewares.
- Skollro\Alexa\VerifyRequest: Verifies if the request is coming from the Amazon Echo API and checks signatures.
- Skollro\Alexa\VerifyApplicationId: Verifies if the request is intended for your application.
Before middleware
Checking for an access token is a typical use case for a middleware which runs before the request handler.
After middleware
To run a middleware after the request handler, store the result of $next($request, $response) in a temporary variable and return the response later.
Request handlers
Amazon Echo API sends different types of requests to your application. Use those callbacks to implement your skill's logic. You can use invokable classes for better encapsulation.
Responses
You can make use of a fluent and natural syntax for creating responses.
Exceptions
If you throw an exception in a request handler we invoke this callback so you can handle exceptions there.
