Guzzle is a PHP HTTP client library that makes it easy to send HTTP requests and trivial to integrate with web services. It allows you to send HTTP/1.1 requests with various methods like GET, POST, PUT, DELETE, and others.

Guzzle also supports sending both synchronous and asynchronous requests, caching, and even has built-in support for OAuth 1.0a. Additionally, it can handle different HTTP errors and handle redirects automatically. It also has built-in support for serializing and deserializing data using formats like JSON and XML, as well as sending multipart file uploads.

Overall Guzzle is an easy to use and powerful library for working with HTTP in PHP.

HTTPClient is a Ruby gem that provides a simple and flexible interface for making HTTP requests. It's a full-featured HTTP client library with support for cookies, redirects, proxy, and more. It's built on top of the libwww-perl library, which is a widely-used, robust and well-documented library.


  • methods like GET/HEAD/POST/* via HTTP/1.1.
  • HTTPS(SSL), Cookies, proxy, authentication(Digest, NTLM, Basic), etc.
  • asynchronous HTTP request, streaming HTTP request.
  • debug mode CLI.
  • by contrast with net/http in standard distribution;
  • Cookies support
  • MT-safe
  • streaming POST (POST with File/IO)
  • Digest auth
  • Negotiate/NTLM auth for WWW-Authenticate (requires net/ntlm module; rubyntlm gem)
  • NTLM auth for Proxy-Authenticate (requires 'win32/sspi' module; rubysspi gem)
  • extensible with filter interface
  • you don't have to care HTTP/1.1 persistent connection (httpclient cares instead of you)

Example Use

use GuzzleHttp\Client;

// Create a client session:
$client = new Client();
// can also set session details like headers
$client = new Client([
    'headers' => [
        'User-Agent' => '',

// GET request:
$response = $client->get('');
// print all details
// or the important bits
printf("status: %s\n", $response->getStatusCode());
printf("headers: %s\n", json_encode($response->getHeaders(), JSON_PRETTY_PRINT));
printf("body: %s", $response->getBody()->getContents());

// POST request
$response = $client->post(
// for JSON use json argument:
    ['json' => ['query' => 'foobar', 'page' => 2]]
// or formdata use form_params:
//  ['form_params' => ['query' => 'foobar', 'page' => 2]]

// For ASYNC requests getAsync function can be used:
$promise1 = $client->getAsync('');
$promise2 = $client->getAsync('');
// await it:
$results = Promise\unwrap([$promise1, $promise2]);
foreach ($results as $result) {
    echo $result->getBody();
// or add promise callback
Promise\each([$promise1, $promise2], function ($response, $index, $callable) {
    echo $response->getBody();
require 'httpclient'

client =
# GET requests
response = client.get("")
puts response.content

# POST requests
data = { name: "value" }
response ="", data)
puts response.content
