Simple HTTP client

Status

Work in progress!

Motivation

Create simple to use http client with minimum dependencies.

• Laravel style
• No dependencies
• Nice fluid interface
• JSON by default
• Code completion
• No magic
• Strict types where possible
• PHP 7.0
• Fully tested
• Easily extendable
• Throw exception on any error (non-2xx status, too many redirects, json_decode error, etc)

Simple example

require_once "vendor/autoload.php";

use Jttp\Jttp;
use Jttp\JttpException;

try {
    $response = (new Jttp)
        ->url("https://httpbin.org/get")
        ->get();

    echo "Status:   " . $response->status() . "\n\n";
    echo "Headers:  " . var_export($response->headers(), true) . "\n\n";
    echo "Body:     " . $response->body() . "\n\n";
    echo "Json:     " . var_export($response->json(), true) . "\n\n";
} catch (JttpException $e) {
    // it will catch all errors here including non 2xx response codes and json_decode errors
    echo "Error: {$e->getMessage()}\n";
}

Other fluid methods

->maxRedirects(5)               // follow maximum 5 redirects
->doNotFollowRedirects()

->asMultipart()                 // send request as multipart/form-data

->logToStderr()                 // enables logging debug information to stderr
->logToFile($filename = "")     // log to file

->retries(1)                    // retry request on network errors, remote server errors, etc 
->pauseBetweenRetriesMs(1000)   // in milliseconds

All http verbs

->get()
->post($data = null)
->put($data = null)
->patch($data = null)
->delete($data = null)

More complex example

If you are making a few request or just want to have client with the same setting - you can prepare client and use it many times like this:

// prepare http client
$client = (new Jttp)
    ->retries(2)
    ->redirects(5)
    ->logToFile("log.txt")
    ->pauseBetweenRetriesMs(1000);
        
try {
    // use it for first request
    echo "Get request: \n";
    $response = $client->url("https://httpbin.org/get")
                       ->get();
    var_dump($response->json());

    // use for second request to other url
    echo "Patch request: \n";
    $response = $client->url("https://httpbin.org/patch")
                       ->patch(["Key" => "value"]);
    var_dump($response->json());

} catch (JttpException $e) {
    // it will catch all errors here including non 2xx response codes and json_decode errors, too many redirects, etc
    echo "Error: {$e->getMessage()}\n";
}

You can try to run examples.php and copy-paste from it.

Advanced features

You will know when you need them :) Normally it will happen if need to customize functionality of internal classes or for tests.

Different transports

Default transport is Curl. But if you want to implement your own transport or extend functionality of this Curl transport - you are free to do it.

Extending

// extend Curl
class CustomTransport extends Curl
{
    // extend however you want...
}

// and use
$response = (new Jttp)
    ->useTransport((new CustomTransport()))
    ->url("https://httpbin.org/get")
    ->get();

Fully custom transport

class CustomTransport implements TransportInterface
{

    public function setResponseObject(Response $response)
    {
        // TODO: Implement setResponseObject() method.
    }

    /**
     * @param string $method
     * @param string $url
     * @param mixed $data
     * @param bool $verbose
     * @return Response
     * @throws TransportException
     */
    public function call(string $method, string $url, string $body_format, $data = null, bool $verbose = false, $log_handler = null): Response
    {
        // TODO: Implement call() method.
    }
}

// and use
$response = (new Jttp)
    ->useTransport((new CustomTransport()))
    ->url("https://httpbin.org/get")
    ->get();

Custom response objects

// extend original class
class CustomResponse extends Response
{
    public function customMethod()
    {
        return "ok";
    }
}

// and inject info Jttp to use
$response = (new Jttp)
    ->useResponseObject(new CustomResponse())
    ->url("https://httpbin.org/get")
    ->get();
    
// use you response
echo $response->customMethod();
