Laravel guzzle http client: Complete Guide

In a real-world scenario, we use Guzzle Http Client to send a request from the Laravel server to third-party servers like Github API, Facebook API, Payment apis like Paypal or Stripe. In this example, I am not sending the Network request to any of these APIs, but I will create my Laravel server and communication between those two servers. Thus, it is a kind of server-to-server communication.

Many years ago, we used cURL for the same purpose. But in this example, I am using Guzzle Http Client Library to get work done.

Laravel guzzle http client

The guzzlehttp/guzzle package is used for GET and POST requests. In this example, we use laravel and guzzle. We will create two Laravel projects for this tutorial because the First Laravel project will become a Consumer project, and the second Laravel project will be our Producer Laravel Project.

First, we install two new Laravel projects. One Project is For Consuming API and the Second is For Creating API.

Step 1: Install Laravel Project

 Now we install the Consuming API Project.

composer create-project --prefer-dist laravel/laravel laravelguzzle

Go into the project folder.

cd laravelguzzle

Start the development server with the following command.

php artisan serve

After successfully installing the first project, we install the second Project.

composer create-project --prefer-dist laravel/laravel laravelguzzlepost

Go into that folder.

cd laravelguzzlepost

We have already started the Laravel development server at port: 8000. So this time, we need to start the server at a different port, and you can change the port using the following command.

php artisan serve --port=8001

Step 2: Install guzzlehttp/guzzle Package.

We will install the guzzlehttp/guzzle package by typing the following command in cmd.

composer require guzzlehttp/guzzle:~6.0

Step 3: Create Controller For First Project

php artisan make:controller DataController --resource

It will create one controller file called DataController.php.

We register the first Project route in routes  >>  web.php file. So let us do it.

Route::get('post','DataController@postRequest');
Route::get('get','DataController@getRequest');

Step 4: Setup MySQL database For Second Project

Now, configure this database in the .env file.

//.env

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=laravelguzzle
DB_USERNAME=root
DB_PASSWORD=

Move to your terminal and hit the following command.

php artisan migrate

Step 5: Construct a model and migration file

Type the following command in your terminal.

php artisan make:model GuzzlePost -m

It will create two files.

1. GuzzlePost.php model.
2. create__guzzle_posts_table migration file.

We need to create Schema for the passports table. So navigate to Laravel  >>  database  >>  migrations  >>  create__guzzle_posts_table.

//create__guzzle_posts_table
public function up()
    {
        Schema::create('guzzle_posts', function (Blueprint $table) {
            $table->increments('id');
            $table->string('name');
            $table->timestamps();
        });
    }

Step 6: Create Controller For Second Project

php artisan make:controller GuzzlePostController --resource

It will create one controller file called GuzzlePostController.php.

We register the second Project route in routes  >>  api.php file. So let us do it.

//api.php

Route::post('store', 'GuzzlePostController@store');
Route::get('index', 'GuzzlePostController@index');

Step 7: Guzzle http client POST request

Next, we will send a post request to the Second Project.

// DataContoller.php

public function postRequest()
{
    $client = new \GuzzleHttp\Client();
    $response = $client->request('POST', 'http://localhost:8001/api/store', [
        'form_params' => [
            'name' => 'krunal',
        ]
    ]);
    $response = $response->getBody()->getContents();
    echo '<pre>';
    print_r($response);
}

We can store data in the Second Project GuzzlePostController file.

//GuzzlePostController.php

public function store(Request $request)
    {
        $data = new GuzzlePost();
        $data->name=$request->get('name');
        $data->save();
        return response()->json('Successfully added');

    }

Step 8: Guzzle http client GET request

Next, we have to get the request for the Second Project.

// DataContoller.php

public function getRequest()
    {
        $client = new \GuzzleHttp\Client();
        $request = $client->get('http://localhost:8001/api/index');
        $response = $request->getBody()->getContents();
        echo '<pre>';
        print_r($response);
        exit;
    }

We can retrieve data in the index function.

// GuzzlePostController.php

public function index()
    {
        $data = GuzzlePost::all();
        return response()->json($data);
    }

Finally, Our Laravel guzzle http client Example is over. Thanks for taking it.
