Features

• Responses create php://temp response body stream and swap to disk when necessary.
• cURL (default) and Stream Context handlers supported.
• Middleware support out of the box.
• Easy body transformations when creating requests with JsonBody, FormBody, and XmlBody helper classes.

Not features

• Asynchronous calls.

Making requests: The easy way

The quickest and easiest way to begin making requests in Shuttle is to use the HTTP method name:

use Nimbly\Shuttle\Shuttle;

$shuttle = new Shuttle;

$response = $shuttle->get("https://www.google.com");
$response = $shuttle->post("https://example.com/search", "Form data"));

Shuttle has built-in methods to support the major HTTP verbs: get, post, put, patch, delete, head, and options. However, you can make any HTTP verb request using the request method directly.

$response = $shuttle->request("connect", "https://api.example.com/v1/books");

Handling responses

Responses in Shuttle implement PSR-7 ResponseInterface and as such are streamable resources.

$response = $shuttle->get("https://api.example.com/v1/books");

echo $response->getStatusCode(); // 200
echo $response->getReasonPhrase(); // OK
echo $response->isSuccessful(); // true

$body = $response->getBody()->getContents();

Handling failed requests

Shuttle will throw a RequestException by default if the request failed. This includes things like host name not found, connection timeouts, etc.

Responses with HTTP 4xx or 5xx status codes will not throw an exception and must be handled properly within your business logic.

Making requests: The PSR-7 way

If code reusability and portability is your thing, future proof your code by making requests the PSR-7 way. Remember, PSR-7 stipulates that Request and Response messages be immutable.

// Build Request message with your favorite PSR-7 library.
$request = new Request("get", "https://www.example.com");

// Send the Request.
$shuttle = new Shuttle;
$response = $shuttle->sendRequest($request);

Request bodies

An easy way to submit data with your request is to use the \Shuttle\Body\* helper classes. These classes will automatically transform the data, convert to a BufferStream, and set a default Content-Type header on the request.

The request bodies support are:

• JsonBody Converts an associative array into JSON, sets Content-Type header to application/json.
• FormBody Converts an associative array into a query string, sets Content-Type header to application/x-www-form-urlencoded.
• XmlBody Does no conversion of data, sets Content-Type header to application/xml.

To submit a JSON payload with a request:

use Nimbly\Shuttle\Body\JsonBody;

$book = [
    "title" => "Breakfast Of Champions",
    "author" => "Kurt Vonnegut",
];

$shuttle->post("https://api.example.com/v1/books", new JsonBody($book));
