How to autoload Guzzle in Laravel 4?

问题

How can I autoload Guzzle in Laravel 4?

I am encountering the following error when I try to create a new GuzzleHttp/Client:

Symfony \ Component \ Debug \ Exception \ FatalErrorException
Class 'GuzzleHttp\Client' not found

I have the following set up in my composer.json autoload section:

autoload: {
    "psr-0": {
        "Guzzle\\": "src/"
    }
}

You don't need to add Guzzle to your composer.json, it's already autoloaded by it's own composer.json.

Guzzle 4

PHP 5.4.x+ required

composer require "guzzlehttp/guzzle" "~4.0"

Create a client:

$client = new \GuzzleHttp\Client();

Get results:

$response = $client->get('http://api.github.com/users/antonioribeiro');

dd($response->getBody());

Guzzle 3

Install it:

composer require "guzzle/guzzle" "~3.0"

Create a client setting the base URL:

$client = new \Guzzle\Service\Client('http://api.github.com/users/');

Get your response:

$username = 'antonioribeiro';

$response = $client->get("users/$username")->send();

And display it:

dd($response);

If you still don't get it running, check the file vendor/composer/autoload_psr4.php, Guzzle must appear in it. If it doesn't, remove your vendor folder and install it again:

rm -rf vendor
rm composer.lock
composer install
