Talk about laravel guzzle asynchronous request problem

Laravel Guzzle is an HTTP client in the Laravel framework. It provides a simple and powerful interface that allows us to easily send HTTP requests and obtain HTTP responses. Especially in asynchronous request scenarios, Laravel Guzzle can improve our performance and response speed.

Generally, we need to communicate with the server through the HTTP client, pass entities or request parameters, and then get the response from the server, as shown below:

$client = new Client(['base_uri' => 'http://httpbin.org']);
$response = $client->request('GET', '/get', ['timeout' => 2]);
echo $response->getBody();

In this example, we Use Guzzle's Client class to create a base URI pointing to the httpbin.org website and create a GET request with a timeout set to 2 seconds. Then we get the response content through the $response->getBody() method.

However, when we need to make large batch requests, this synchronous request method will quickly consume our server resources and reduce our service performance and response speed. At this point, asynchronous requests can help us.

Asynchronous requests refer to requests that do not need to wait for a response from the server, but only need to distribute the request to the server and then continue with subsequent operations. When the server responds to the request, we obtain the response content in a certain way. This approach can greatly improve our service performance and response speed.

Next, let’s take a look at how Laravel Guzzle implements asynchronous requests:

$client = new \GuzzleHttp\Client();
$promises = [
    $client->getAsync('http://httpbin.org/get'),
    $client->getAsync('http://httpbin.org/get?foo=bar'),
    $client->getAsync('http://httpbin.org/get?baz=qux')
];

$results = GuzzleHttp\Promise\unwrap($promises);

foreach ($results as $result) {
    echo $result->getBody();
}

In this example, we use Guzzle’s getAsync method to send an asynchronous request and return the The promise object is put into the $promises array. When we need to get the response content, use Guzzle's unwrap method to get the results of all promises, then loop through the results, and get the response content through the $result->getBody() method.

In summary, Laravel Guzzle, as the HTTP client of the Laravel framework, has good performance in asynchronous requests and can help us improve service performance and response speed. Asynchronous requests are a very good solution when we need to make large batch requests.
