How to autoload Guzzle in Laravel 4?

Question

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/"
    }
}

Solution

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

Where is this located ? Full path and how did you install it ?

[Iain]

Thanks Antonio, this works. This seems to differ from the documentation (or should I learn to rtfm properly?) as it suggests creating a new client by calling use GuzzleHttp\Client and then $client = new Client() which is what was giving me the errors. Can you enlighten me, please?

[Iain]

To clarify, the docs I was reading are located here docs.guzzlephp.org/en/latest

[Antonio Carlos Ribeiro]

Oh! Looks like the docs are talking about the wrong namespace, somehow... But it could not be so wrong, right? I'll try to take a look at it later.

Guzzle came up with the idea to rename the namespace they were using when going from version 3 (using \Guzzle) to 4 (using \GuzzleHttp). They say they did it to allow using both versions concurrently, which is technically correct, but in the end it behaves like a completely different product now.

[Sven]

And I am "-1" this, because NEVER EVER suggest installing branches like "dev-master" if you can by all means avoid it. Guzzle is an excellent example of a software using semantic versioning - there is absolutely no reason to not install a numbered version like ~4.0. Additionally, using a version would make it clear that you are talking about 3.x instead of 4.x.

[Antonio Carlos Ribeiro]

Thanks for your suggestion, Sven. I'm still in the early stages of my php+composer+laravel+webdevelopment learnship, so I would like to ask you to extend your lesson to Jeffrey Way, which may have used dev-master, unfortunatelly, in a dozen+ of Laracasts videos and he could be, this way, in the processes of confusing many more people like me. Changing (edited) to ~3.0 may have made it clear, but still downloaded guzzle and guzzlehttp dev-master, as you can see here: laravel.io/bin/Q5Qa.

I'm using Guzzle that is installed with Laravel 4.0. The FQN for the client is \Guzzle\Http\Client() rather than \GuzzleHttp\Client(). This differs from the documentation for both Guzzle 3 and 4.
