Yii2 HTTP client

Installation

Recommended way to install this extenstion is through Composer:

php composer.phar require understeam/yii2-httpclient:~1.0 --prefer-dist

Configuration

Add this lines to your config file:

...
'components' => [
	'httpclient' => [
		'class' =>'understeam\httpclient\Client',
		'detectMimeType' => true, // automatically transform request to data according to response Content-Type header
		'requestOptions' => [
		    // see guzzle request options documentation
		],
		'requestHeaders' => [
		    // specify global request headers (can be overrided with $options on making request)
		],
	],
],
...

Basic usage

Performing HTTP GET request with mime type detection:

// Result is html text
$text = Yii::$app->httpclient->get('http://httpbin.org/html');

// Result is SimpleXMLElement containing parsed XML
$xml = Yii::$app->httpclient->get('http://httpbin.org/xml');

// Result is parsed JSON array
$json = Yii::$app->httpclient->get('http://httpbin.org/get');

You can disable this behavior by specifying $detectMimeType option to whole component or single call

// Result is Guzzle `Response` object
$text = Yii::$app->httpclient->get('http://httpbin.org/xml', [], false);

Make request with custom options:

$text = Yii::$app->httpclient->get('http://httpbin.org/xml', [
    'proxy' => 'tcp://localhost:8125'
]);

Read more about this options in Guzzle 6 documentation

HTTP methods

You can make request with several ways:

1. Call shortcut method (get(), post(), put(), delete(), etc.)
2. Call request() method

All shortcut methods has the same signature except get():

// Synchronous GET request
Yii::$app->httpclient->get(
    $url, // URL
    [], // Options
    true // Detect Mime Type?
);

// Synchronous POST (and others) request
Yii::$app->httpclient->post(
    $url, // URL
    $body, // Body
    [], // Options
    true // Detect Mime Type?
);

// Asynchronous GET request
Yii::$app->httpclient->getAsync(
    $url, // URL
    [] // Options
);

// Asynchronous POST (and others) request
Yii::$app->httpclient->postAsync(
    $url, // URL
    $body, // Body
    [] // Options
);

NOTE: you still can make a GET request with body via request() function

Asynchronous calls

To make an asynchronous request simly add Async to end of request method:

// PromiseInterface
$promise = Yii::$app->httpclient->postAsync('http://httpbin.org/post');

NOTE: mime type detection is not supported for asynchronous calls

Read more about asynchronous requests in Guzzle 6 documentation

Request body

Types you can pass as a body of request:

1. Arrayable object (ActiveRecord, Model etc.) - will be encoded into JSON object
2. Array - will be sent as form request (x-form-urlencoded)

Any other data passed as body will be sent into Guzzle without any transformations.
