PHP Nano Rest

Easy-to-use self-containing lightweight package to deal with cURL requests.

Such packages as Guzzle are great of course, but they are too heavy for small projects. You don't need an overkill package for some easy stuff, and that's when something small and neat may help.

Requirements

• PHP >= 7.1;
• cURL extension.

Installation

Require the package using command line:

composer require "gino-pane/nano-rest:1.*"

or just put a new dependency in your existing composer.json and run composer install after that:

"require": {
    ...
    "gino-pane/nano-rest": "1.*"
}

Usage

Project's philosophy implies usage of RequestContext and ResponseContext objects. RequestContext aggregates request settings whilst ResponseContext contains response data.

Response context can be typed. Currently only JsonResponseContext available for JSON responses. Response type must be set explicitly by user. If no response type set, DummyResponseContext will be used.

Please take a look at examples below, which may clarify everything.

POST some data to endpoint

require './vendor/autoload.php';

$nanoRest = new NanoRest();

//create request context
$requestContext = (new RequestContext('http://httpbin.org/post')) //pass URL to constructor
    ->setMethod(RequestContext::METHOD_POST) //set request method. GET is default
    ->setRequestParameters([ //set some request parameters. They will be attached to URL
        'foo' => 'bar'
    ])
    ->setData('Hello world!') //set request data for body
    ->setContentType(RequestContext::CONTENT_TYPE_TEXT_PLAIN) //being set by default
    ->setHeaders([ // set some headers for request
        'bar' => 'baz'
    ])
    ->setResponseContextClass(JsonResponseContext::class); //explicitly set expected response type

$responseContext = $nanoRest->sendRequest($requestContext);

$responseContext->getHttpStatusCode(); //200
$responseContext->hasHttpError() //false

$responseContext->getArray();

/**
array(8) {
  'args' =>
  array(1) {
    'foo' =>
    string(3) "bar"
  }
  'data' =>
  string(12) "Hello world!"
  'files' =>
  array(0) {
  }
  'form' =>
  array(0) {
  }
  'headers' =>
  array(8) {
    'Accept' =>
    string(3) "*/*"
    'Accept-Encoding' =>
    string(13) "deflate, gzip"
    'Bar' =>
    string(3) "baz"
    'Connection' =>
    string(5) "close"
    'Content-Length' =>
    string(2) "12"
    'Content-Type' =>
    string(25) "text/plain; charset=UTF-8"
    'Host' =>
    string(11) "httpbin.org"
    'User-Agent' =>
    string(13) "php-nano-rest"
  }
  'json' =>
  NULL
  'origin' =>
  string(12) "93.85.47.181"
  'url' =>
  string(31) "http://httpbin.org/post?foo=bar"
}

RequestContext provides setCurlOption/setCurlOptions which allow to override default cURL options and customize request for all your needs. Please examine source code and provided IntegrationTest carefully to get the whole idea.

Change the way how request query is generated

By default http_build_query encodes arrays using PHP square brackets syntax, like this:

?text[0]=1&text[1]=2&text[2]=3

But sometimes you'll want it to work like this instead:

?text=1&text=2&text=3

Or even in some other custom-defined way.

That's why setEncodeArraysUsingDuplication and setHttpQueryCustomProcessor methods were added to RequestContext:

$url = "http://some.url";
$data = ['text' => [1,2,3]];

$request = (new RequestContext($url))
            ->setRequestParameters($data)
            ->setEncodeArraysUsingDuplication(false);

$requestUrl = $request->getRequestUrl(); //http://some.url?text%5B0%5D=1&text%5B1%5D=2&text%5B2%5D=3

$request = (new RequestContext($url))
            ->setRequestParameters($data)
            ->setEncodeArraysUsingDuplication(true);

$requestUrl = $request->getRequestUrl(); //http://some.url?text=1&text=2&text=3

Method setHttpQueryCustomProcessor allows you to set your custom Closure that will be called on HTTP query string so you could process it as you wish. Initial request $data array will be passed to it as a second parameter.

$url = "http://some.url";
$data = ['text' => [1,2,3]];

$request = (new RequestContext($url))
            ->setRequestParameters($data)
            ->setEncodeArraysUsingDuplication(true);
            
$request->setHttpQueryCustomProcessor(
    function (string $query, array $data) {
        return str_replace('text', 'data', $query);
    }
);

$requestUrl = $request->getRequestUrl(); //http://some.url?data=1&data=2&data=3
