Caddy v2 allows you to update your Caddy configuration via a JSON API. This package is a simple helper library to update parts of your configuration.
Functionality for updating all aspects of the configuration will be added over time.
## Usage
To get started, create an instance of `OhSeeSoftware\CaddyConfig\Client`, ensuring to pass your Caddy network address as the first argument:
```php
$client = new OhSeeSoftware\CaddyConfig\Client('localhost:2019');
```
From there, you can use the `$client` instance to make API requests to your Caddy instance.
The idea behind the wrapper is that you can have a `Client` singleton class, and then use the `$client->request()` method to create new `Request` instances. You should create a new `Request` instance per HTTP request you send to your Caddy server.
## API Methods
### Client
**__constructor()**
Creates a new instance of the `Client` class.
Arguments:
* `$caddyHost` - _string_: The address where the [Caddy config endpoint](https://github.com/caddyserver/caddy/wiki/v2:-Documentation#admin) is listening.
**setCaddyHost()**
Allows you to change the Caddy host after creating the Client instance.
Arguments:
* `$caddyHost` - _string_: The address where the [Caddy config endpoint](https://github.com/caddyserver/caddy/wiki/v2:-Documentation#admin) is listening.
**request()**
Returns a new `Request` instance which you use to make configuration requests.
No arguments.
### Request
Use the `Request` class to compose your request to send to Caddy. Here's an example of how you can add a new host to a server:
```php
$client = new OhSeeSoftware\CaddyConfig\Client('localhost:2019');
$client->request()
->http()
->server('srv0')
->route(0)
->match(0)
->addHost('example.com');
```
**__constructor()**
Creates a new instance of the `Request` class.
Arguments:
* `$caddyHost` - _string_: The address where the [Caddy config endpoint](https://github.com/caddyserver/caddy/wiki/v2:-Documentation#admin) is listening.
**addHost()**
Sends a request to Caddy to add the given host.
Arguments:
* `$host` - _string_: The host to add.
Returns:
* `Response` - The response from Caddy wrapped in a `Response` instance.
**http()**
Adds the http path, "/apps/http", to the request URI.
No arguments.
Returns:
* `Request` - The request instance (allows chaining).
**server()**
Adds the server path, "/servers/{server}", to the request URI.
Arguments:
* `$server` - _string_: The name of the server to target.
Returns:
* `Request` - The request instance (allows chaining).
**route()**
Adds the route path, "/routes/{routeIndex}", to the request URI.
Arguments:
* `$routeIndex` - _int_: The route to target.
Returns:
* `Request` - The request instance (allows chaining).
**match()**
Adds the match path, "/match/{matchIndex}", to the request URI.
Arguments:
* `$matchIndex` - _int_: The match to target.
Returns:
* `Request` - The request instance (allows chaining).
**sendRequest()**
Sends the built request to the Caddy server.
Arguments:
* `$method` - _string_: The method for the request.
* `$body` - _array|nuullable_: The request body to send to Caddy.
Returns:
* `Response` - A new instance of a `Response` instance.
### Response
**__constructor()**
Creates a new instance of the `Response` class.
Arguments:
* `$response` - _ResponseInterface_: Instance of a `ResponseInterface` (created by Guzzle).
**getBody()**
Returns the response body as a string.
No arguments.
**isSuccessful()**
Returns a boolean indicating if the request was successful. Status codes of 200 or 201 are considered successful, everything else is not.
No arguments.
