Http

HTTP client for sending HTTP requests., _(*1)

Installation

composer require "arturdoruch/http"

Usage

Basic usage

use ArturDoruch\Http\Client;

$client = new Client();
// Send GET request.
$response = $client->get('http://httpbin.org/get');

// Get response status code.
$statusCode = $response->getStatusCode();

// Get response body.
$body = $response->getBody();

// Display response raw headers and body.
echo $response;

// Display response headers.
foreach ($response->getHeaders() as $name => $value) {
    echo sprintf("%s: %s\n", $name, $value);
}

Creating a client

use ArturDoruch\Http\Cookie\CookieFile;
use ArturDoruch\Http\Client;

// Set the cURL options, which will be used for send every HTTP request.
$curlOptions = [
    'followlocation' => false,
    'timeout' => 120
];

// Enabled or disabled throwing RequestException, when request is complete and response status code is 4xx, 5xx or 0.
$throwExceptions = true;

// Set file where all HTTP session cookies should be stored.
$cookieFile = new CookieFile('path/to/cookies.txt');

$client = new Client($curlOptions, $throwExceptions, $cookieFile);

Sending requests

Request can be send with dedicated methods:, _(*2)

$response = $client->get('http://httpbin.org/get');
$response = $client->post('http://httpbin.org/post');
$response = $client->patch('http://httpbin.org/patch');
$response = $client->put('http://httpbin.org/put');
$response = $client->delete('http://httpbin.org/delete');

or by request() method, with prepared the ArturDoruch\Http\Request object., _(*3)

use ArturDoruch\Http\Request;

$request = new Request('DELETE', 'http://httpbin.org/delete');
$response = $client->request($request);

Sending multi (parallel) requests

$requests = [
    // The list of ArturDoruch\Http\Request objects or URLs to send. 
];
$responses = $client->multiRequest($requests);

foreach ($responses as $response) {
    var_dump($response->getBody());
}

Sending form data (parameters)

$formData = [
    'name' => 'value',
    'choices' => [1, 2, 3]
];

$response = $client->post('http://httpbin.org/post', $formData);

$request = new Request('POST', 'http://httpbin.org/post', $formData);
$response = $client->request($request);

Form data can be send only with the request methods: POST, PUT, PATCH and DELETE. For other methods form data will be used as the URL query parameters., _(*4)

Request options

Request options can be set with dedicated methods on the ArturDoruch\Http\Request object, or as the third argument in the Client::get(), Client::post(), etc. methods, or as the fourth argument in the Client::createRequest() method., _(*5)

cookie string, _(*6)

Sets the cookie to send. The cookie format must conform to the specification., _(*7)

$client->get('/get', [], [
    'cookie' => 'NAME=VALUE; expires=DATE; path=PATH; domain=DOMAIN_NAME; secure'
]);

headers array, _(*8)

$client->get('/get', [], [
    'headers' => [
        'User-Agent' => 'testing/1.0',
        'Accept' => 'application/json',
        'X-Foo' => ['Bar', 'Baz']
    ]
]);

body string|resource, _(*9)

Sets the body plain text. If the Content-Type header is not specified then will be set to text/plain., _(*10)

// Send body as plain text taken from a resource.
$resource = fopen('http://httpbin.org', 'r');
$client->post('/post', [], ['body' => $resource]);

// Send plain text.
$client->post('/post', [], ['body' => 'Raw data']);

json array, _(*11)

Sets the body to JSON data. If the Content-Type header is not specified then will be set to application/json., _(*12)
```
$client->post('/post', [], [
    'json' => [
        'foo' => 'bar',
        'key' => 'value'
    ]
]);
```

multipart array, _(*13)

Sets the body to a multipart form data. For sending file create the ArturDoruch\Http\Message\FormFile object and pass as the form field value. If the Content-Type header is not specified then will be set to multipart/form-data; boundary=., _(*14)

use ArturDoruch\Http\Message\FormFile;

$client->post('/post', [], [
    'multipart' => [
        'name' => 'value',
        'categories' => [
            'animals' => ['dog', 'cat'],
        ],
        'file' => new FormFile('/path/file.txt.', 'optional-custom-filename.txt')
    ]        
]);

HTTP request events

While HTTP request is sending, are called two events:, _(*15)

request.before - Called before sending the request.
request.complete - Called when the request is done.

To add listeners for those events call the Client::addListener() method. Registered listeners receives argument depend on the event to listen for. One of the:, _(*16)

ArturDoruch\Http\Event\BeforeEvent - for the request.before event
ArturDoruch\Http\Event\CompleteEvent - for the request.complete event

use App\EventListener\HttpRequestListener;
use ArturDoruch\Http\Event\BeforeEvent;
use ArturDoruch\Http\Event\CompleteEvent;
use ArturDoruch\Http\Event\RequestEvents;

// Add listener to request.before event as anonymous function.
$client->addListener(RequestEvents::BEFORE, function (BeforeEvent $event) {
    $request = $event->getRequest();
});

// Add listener to request.before event as method class.
$client->addListener(RequestEvents::BEFORE, [new HttpRequestListener(), 'onBefore']);

// Add listener to request.complete event as method class.
$client->addListener(RequestEvents::COMPLETE, [new HttpRequestListener(), 'onComplete']);

Example of the HttpRequestListener class., _(*17)

namespace App\EventListener;

use ArturDoruch\Http\Event\BeforeEvent;
use ArturDoruch\Http\Event\CompleteEvent;

class HttpRequestListener
{    
    /**
     * @param BeforeEvent $event
     */
    public function onBefore(BeforeEvent $event)
    {
        $request = $event->getRequest();
        // Do some actions before HTTP request is sending.
    }

    /**
     * @param CompleteEvent $event
     */
    public function onComplete(CompleteEvent $event)
    {
        $response = $event->getResponse();
        // Do some actions when HTTP request is complete.
    }
}

Convert Response object to array or json

In order to convert Response object to array call Response::toArray() method., _(*18)

$responseArray = $response->toArray();

In order to convert Response object to json call Response::toJson() method., _(*19)

$responseJson = $response->toJson();
// Use JSON_PRETTY_PRINT option to format output json
$responseJson = $response->toJson(true);

To determine which Response object properties should be available in converted output value use Response::expose() method. This method takes an argument "properties" with list of properties names to expose. Available names are:, _(*20)

protocol
statusCode
reasonPhrase
headers
headerLines
body
contentType
requestUrl
effectiveUrl
errorMsg
errorNumber
curlInfo

As default are exposed properties: statusCode, headers, body., _(*21)

// Expose only the "statusCode" and "body" properties.
$response->expose([
    'statusCode',
    'body',
]);    
// The array will contain only "statusCode" and "body" keys.    
$responseArray = $response->toArray();

To expose all Response properties use exposeAll() method., _(*22)

// Expose all properties.
$response->exposeAll();    
// The array will contain all of available properties.  
$responseArray = $response->toArray();

Tips

Get actually sent request headers., _(*23)

$client = new Client([CURLINFO_HEADER_OUT => true]);

$response = $client->get('http://httpbin.org/get');
$curlInfo = $response->getCurlInfo()

$requestHeaders = $curlInfo['request_header'];
