Doing HTTP requests FROM Laravel to an external API

Question

What I want is get an object from an API with a HTTP (eg, jQuery's AJAX) request to an external API. How do I start? I did research on Mr Google but I can't find anything helping.

I'm starting to wonder if this is even possible. In this post Laravel 4 make post request from controller to external url with data it looks like it can be done. But there's no example nor any source where to find some documentation.

Answer 1

Based upon an answer of a similar question here: https://stackoverflow.com/a/22695523/1412268

Take a look at Guzzle

$client = new GuzzleHttp\Client();
$res = $client->get('https://api.github.com/user', ['auth' =>  ['user', 'pass']]);
echo $res->getStatusCode(); // 200
echo $res->getBody(); // { "type": "User", ....

We can use package Guzzle in Laravel, it is a PHP HTTP client to send HTTP requests.

You can install Guzzle through composer

composer require guzzlehttp/guzzle:~6.0

Or you can specify Guzzle as a dependency in your project's existing composer.json

{
   "require": {
      "guzzlehttp/guzzle": "~6.0"
   }
}

Example code in laravel 5 using Guzzle as shown below,

use GuzzleHttp\Client;
class yourController extends Controller {

    public function saveApiData()
    {
        $client = new Client();
        $res = $client->request('POST', 'https://url_to_the_api', [
            'form_params' => [
                'client_id' => 'test_id',
                'secret' => 'test_secret',
            ]
        ]);
        echo $res->getStatusCode();
        // 200
        echo $res->getHeader('content-type');
        // 'application/json; charset=utf8'
        echo $res->getBody();
        // {"type":"User"...'
}

As of Laravel v7.X, the framework now comes with a minimal API wrapped around the Guzzle HTTP client. It provides an easy way to make get, post, put, patch, and delete requests using the HTTP Client:

use Illuminate\Support\Facades\Http;

$response = Http::get('http://test.com');
$response = Http::post('http://test.com');
$response = Http::put('http://test.com');
$response = Http::patch('http://test.com');
$response = Http::delete('http://test.com');

You can manage responses using the set of methods provided by the Illuminate\Http\Client\Response instance returned.

$response->body() : string;
$response->json() : array;
$response->status() : int;
$response->ok() : bool;
$response->successful() : bool;
$response->serverError() : bool;
$response->clientError() : bool;
$response->header($header) : string;
$response->headers() : array;

Please note that you will, of course, need to install Guzzle like so:

composer require guzzlehttp/guzzle

There are a lot more helpful features built-in and you can find out more about these set of the feature here: https://laravel.com/docs/7.x/http-client

This is definitely now the easiest way to make external API calls within Laravel.

Answer 4

You just want to call an external URL and use the results? PHP does this out of the box, if we're talking about a simple GET request to something serving JSON:

$json = json_decode(file_get_contents('http://host.com/api/stuff/1'), true);

If you want to do a post request, it's a little harder but there's loads of examples how to do this with curl.

So I guess the question is; what exactly do you want?

Answer 5

Add GuzzleHttp package using composer require guzzlehttp/guzzle:~6.3.3

Or you can specify Guzzle as a dependency in your project's composer.json

{
   "require": {
      "guzzlehttp/guzzle": "~6.3.3"
   }
}

Include below line in the top of the class where you are calling the API

use GuzzleHttp\Client;

Add below code for making the request

$client = new Client();

$res = $client->request('POST', 'http://www.exmple.com/mydetails', [
    'form_params' => [
        'name' => 'george',
    ]
]);

if ($res->getStatusCode() == 200) { // 200 OK
    $response_data = $res->getBody()->getContents();
}

Definitively, for any PHP project, you may want to use GuzzleHTTP for sending requests. Guzzle has very nice documentation you can check here. I just want to say that, you probably want to centralize the usage of the Client class of Guzzle in any component of your Laravel project (for example a trait) instead of being creating Client instances on several controllers and components of Laravel (as many articles and replies suggest).

I created a trait you can try to use, which allows you to send requests from any component of your Laravel project, just using it and calling to makeRequest.

namespace App\Traits;
use GuzzleHttp\Client;
trait ConsumesExternalServices
{
    /**
     * Send a request to any service
     * @return string
     */
    public function makeRequest($method, $requestUrl, $queryParams = [], $formParams = [], $headers = [], $hasFile = false)
    {
        $client = new Client([
            'base_uri' => $this->baseUri,
        ]);

        $bodyType = 'form_params';

        if ($hasFile) {
            $bodyType = 'multipart';
            $multipart = [];

            foreach ($formParams as $name => $contents) {
                $multipart[] = [
                    'name' => $name,
                    'contents' => $contents
                ];
            }
        }

        $response = $client->request($method, $requestUrl, [
            'query' => $queryParams,
            $bodyType => $hasFile ? $multipart : $formParams,
            'headers' => $headers,
        ]);

        $response = $response->getBody()->getContents();

        return $response;
    }
}

Notice this trait can even handle files sending.

Basic Solution for Laravel 8 is

use Illuminate\Support\Facades\Http;

$response = Http::get('http://example.com');

I had conflict between "GuzzleHTTP sending requests" and "Illuminate\Http\Request;" don't ask me why... [it's here to be searchable]

So looking for 1sec i found in Laravel 8 Doc...

**Guzzle is inside the Laravel 8 Http Request !**

https://laravel.com/docs/8.x/http-client#making-requests

as you can see

https://laravel.com/docs/8.x/http-client#introduction

Laravel provides an expressive, minimal API around the Guzzle HTTP client, allowing you to quickly make outgoing HTTP requests to communicate with other web applications. Laravel's wrapper around Guzzle is focused on its most common use cases and a wonderful developer experience.

It worked for me very well, have fun and if helpful point up!

I also created trait similar to @JuanDMeGonthat's that u can use anywhere in your project.Please check this out

trait ApiRequests
{
    public function get($url, $data = null)
    {
        try {
            $response = Http::get($this->base_url . $url, $data);
        } catch (\Exception $e) {
            info($e->getMessage());
            abort(503);
        }

        if ( $response->status() == 401) {
            throw new AuthenticationException();
        } else if (! $response->successful()) {
           abort(503);
        }

        return $response->json();
    }

    public function post($url, $data = [])
    {
        $token = session()->get('token');
        try {
            $response = Http::acceptJson()->withToken($token)->post($this->base_url . $url, $data);
        } catch (\Exception $e) {
            abort(503);
        }

        if ($response->status() == 401 && !request()->routeIs('login')) {
            throw new AuthenticationException();
        }

        return $response;
    }
 
}

class Controller extends BaseController
{
    protected $base_url;
 
    use AuthorizesRequests, DispatchesJobs, ValidatesRequests, ApiRequests;

    public function __construct()
    {
        $this->base_url = env("BASE_URL","http://192.168.xxxxxxx");
        
        View::share('base_url', $this->base_url);
       
    }
}

Answer 9

Here is the simple call for laravel 9.4

Route::get('/currency', function () {
    $response = Http::withHeaders([
        'x-api-key' => 'prtl6749387986743898559646983194',
    ])->get('https://partners.api.skyscanner.net/apiservices/v3/culture/currencies');
    return response()->json(['status'=> true,'data'=> json_decode($response->body()), 'Message'=>"Currency retrieved successfully"], 200);
});

Don't forget to import

use Illuminate\Support\Facades\Http;
