Laravel Caller

Create HTTP Clients for external services easily

Installation

composer require wendelladriel/laravel-caller

Publish the config file with:

php artisan vendor:publish --provider="WendellAdriel\LaravelCaller\LaravelCallerServiceProvider" --tag=config

Usage

This package provides a wrapper to the HTTP Client from Laravel to create clients for external services in an easy way.

First you need to configure one or more services in the config/caller.php file, the default file has an example of a default service that you configure to use or create new ones based on that:

<?php

return [
    /*
    |--------------------------------------------------------------------------
    | SERVICES
    |--------------------------------------------------------------------------
    |
    | Here you can configure multiple services that you want to create an HTTP Client for.
    | The auth types supported are: basic, digest and token.
    | For more information on these settings check: https://laravel.com/docs/http-client
    |
    */
    'services' => [
        'default' => [
            'url'            => env('CALLER_DEFAULT_URL', 'https://example.com'),
            'timeout'        => env('CALLER_DEFAULT_TIMEOUT', 30),
            'retries'        => env('CALLER_DEFAULT_RETRIES', 0),
            'retry_after'    => env('CALLER_DEFAULT_RETRY_AFTER', 100),
            'cookies_domain' => env('CALLER_DEFAULT_COOKIES_DOMAIN', 'https://example.com'),

            'auth' => [
                'type'       => env('CALLER_DEFAULT_AUTH_TYPE', 'basic'),
                'user'       => env('CALLER_DEFAULT_AUTH_USER', '[email protected]'),
                'password'   => env('CALLER_DEFAULT_AUTH_PASSWORD', 's3Cr3T'),
                'token'      => env('CALLER_DEFAULT_AUTH_TOKEN'),
                'token_type' => env('CALLER_DEFAULT_AUTH_TOKEN_TYPE', 'Bearer'),
            ],

            'headers' => [
                // ADD HEADERS HERE
                // 'X-First' => 'FOO',
            ],

            'cookies' => [
                // ADD COOKIES HERE
                // 'FOO' => 'BAR',
            ],
        ],
    ],
];

After you configure your service(s) you just need to create a Caller class with the service name/key in the config file. For example to create a client to a Twitter service you can use:

<?php

namespace App;

use WendellAdriel\LaravelCaller\Caller;

// YOUR CODE HERE

$twitterClient = new Caller('twitter');
// OR YOU CAN USE THE STATIC METHOD
$twitterClient = Caller::make('twitter');

If you want to create a Caller class for the default service you don't need to pass any params:

<?php

namespace App;

use WendellAdriel\LaravelCaller\Caller;

// YOUR CODE HERE

$twitterClient = new Caller();
// OR YOU CAN USE THE STATIC METHOD
$twitterClient = Caller::make();

Making Requests

With the Caller class you have access to the same methods of the HTTP client from Laravel: head, get, post, put, patch and delete. All of them have the same signature. Check the get method signature below as an example:

<?php

/**
 * @param string $url      - The URL for the request that will be joined with the base URL configured in the service
 * @param array  $params   - The params to be sent to the request
 * @param bool   $asForm   - If the request should be sent as "application/x-www-form-urlencoded"
 * @param bool   $isPublic - If is set to true the auth won't be configured for the request
 * @param array  $headers  - Specific headers for the request that will be merged with the headers configured in the service
 * @param array  $cookies  - Specific cookies for the request that will be merged with the cookies configured in the service
 * @param bool   $debug    - Dumps the outgoing request before it is sent and terminate the script's execution
 * @return Response
 */
public function get(
    string $url,
    array $params,
    bool $asForm = false,
    bool $isPublic = false,
    array $headers = [],
    array $cookies = [],
    bool $debug = false
): Response

Updating the service

If you want to use the same Caller object with different services before doing a new request you can call the setService method with the name/key of the service you want:

<?php

namespace App;

use WendellAdriel\LaravelCaller\Caller;

// YOUR CODE HERE

$client = new Caller(); // USES THE DEFAULT SERVICE
$client->setService('twitter'); // CHANGES TO THE TWITTER SERVICE

Using different Auth credentials

By default, the Caller object will use the auth type and credentials set in the config file. If you need to use different auth credentials per example based on the logged user, you can overwrite those with the methods: setAuthUser, setAuthPassword, setAuthToken

Sending Attachments

If you need to send an attachment on your request, before calling the request use the setAttachment method. This will add the attachment to your next request only. The setAttachment method receives a CallerAttachment object:

<?php

namespace App;

use WendellAdriel\LaravelCaller\Caller;
use WendellAdriel\LaravelCaller\CallerAttachment;

// YOUR CODE HERE

$client = new Caller();
$client->setAttachment(new CallerAttachment('file', file_get_contents('photo.jpg'), 'photo.jpg'));

// THE ATTACHMENT CAN ALSO USE A STREAM RESOURCE AND CAN BE CREATED IN A STATIC WAY
$file = fopen('photo.jpg', 'r');
$client->setAttachment(CallerAttachment::make('file', $file, 'photo.jpg'));
