Doing HTTP requests FROM Laravel to an external AP

问题:

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.

Im starting to wonder is 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.

Please help me out?

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"...'
}

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?

回答4:

If you just need to fire the request to external API, you can use Laravel Request class as follows(Assuming you use GET request)

$request = Request::create('http://your-api.com', 'GET');

But if you need to get the content of the response, You can use Laracurl package as follows:

$response = Laracurl::get('http://your-api.com');
