The GuzzleHttpBundle provide Guzzle clients as Symfony services.


Require the bundle with Composer:

$ composer require m6web/guzzle-http-bundle 

For older Symfony versions, you can try to install an older version of this bundle.

If you don't use Symfony Flex, register the bundle in your kernel:

return [
    // ...
    M6Web\Bundle\GuzzleHttpBundle\M6WebGuzzleHttpBundle => ['all' => true],


Add the m6web_guzzlehttp section in your configuration file. Here is the minimal configuration required.

# app/config/config.yml
        default: ~
            base_uri: "http://domain.tld/"

All subkey under clients defines an instance of guzzle http client. These services are named m6web_guzzlehttp_+subkey expect for the default subkey that define the main service m6web_guzzlehttp.

Then you can ask container for your client:

// in a controller

$client = $this->get('m6web_guzzlehttp'); // default client

try {
    $response = $client->get('http://domain.tld/path/to/resource');

    $promises = [
        'first' => $client->getAsync('http://domain.tld/path/to/resource'),
        'second' => $client->getAsync('http://domain.tld/path/to/other/resource')

    $result = \GuzzleHttp\Promise\Utils::unwrap($promises);
} catch(\GuzzleHttp\Exception\ConnectException $e) {
    // connection problem like timeout

// use other client
$otherClient = $this->get('m6web_guzzlehttp_other');
$response = $otherClient->get('path/to/resource'); // call http://domain.tld/path/to/resource

The service return a configured guzzle client, for more information on how to use it, you can read the guzzle6 documentation.

The only difference with guzzle6 reside in usage of curl for the redirect responses. You can choose to have the guzzle behavior for redirection by setting the configuration key redirect_handler to guzzle.

When a cache system is available, you can use cache_force and cache_ttl in addition of guzzle options than respectively force clear cache before request and use a specific ttl to a request that override configuration.

$client = $this->get('m6web_guzzlehttp');

$response = $client->get('http://domain.tld', ['cache_force' => true]); // remove cache entry and set a new one

$response = $client->get('http://doamin.tld/path', ['cache_ttl' => 200]); // set ttl to 200 seconds instead the default one


A data collector is available when the Symfony profiler is enabled.

It allows you to inspect the following data:

  • Method
  • Url
  • Response code and reason
  • Execution time
  • Redirect count
  • Redirect time
  • Cache hit
  • Cache TTL

NOTE: If you choose Guzzle for redirect_handler, The redirect count and redirect time will always be zero. Cache information are available when a cache system is set.

Cache system

You can set a cache for request by adding in the config the guzzlehttp_cache with service subkey who is a reference to a service implementing M6Web\Bundle\GuzzleHttpBundle\Cache\CacheInterface

# app/config/config.yml
            base_uri: "http://domain.tld/"
                service: my_cache_service

We provide an "In memory" cache class that you can use by defining a new cache service and use it in Guzzle configuration:

# app/config/config.yml
        class: M6Web\Bundle\GuzzleHttpBundle\Cache\InMemory

                service: company.guzzle.cache.inmemory

We also provide a cache interface for Redis with our RedisBundle >= 2.4, than you can use in this way:

# app/config/config.yml
            base_uri: "http://domain.tld/"
                service: m6_redis.guzzlehttp

            ip:   ''
            port: 6379
            servers:   ["default"]     # list of servers to use
            namespace: GuzzleHttp\
            timeout:   2               # timeout in second
            readwritetimeout: 2        # read-write timeout in second
            class: M6Web\Bundle\RedisBundle\CacheAdapters\M6WebGuzzleHttp

For more information on how to set up the RedisBundle, refer to the README in the project.

We provide also the same cache system for APCU through the ApcuBundle.

Configuration reference

As some configuration options accept multiples data types, all services references must start with a @ character.

For the headers options, the key in array represent the header name. The underscore will be transformed to hyphen except if it's escaped by a backslash.

Adding a middleware

Implement M6Web\Bundle\GuzzleHttpBundle\Middleware\MiddlewareInterface.

Tag your service with m6web_guzzlehttp.middleware and specify the client as follows:

            - {name: 'm6web_guzzlehttp.middleware', client: 'myclient' }
