webman/http-client

Description

webman/http-client est un composant client HTTP asynchrone. Toutes les requêtes et réponses sont asynchrones et non bloquantes, avec une piscine de connexions intégrée, les requêtes et réponses sont conformes à la spécification PSR7.

Installation:

composer require workerman/http-client

Exemple:

Utilisation de get post request:

use Workerman\Worker;

require_once __DIR__ . '/vendor/autoload.php';

$worker = new Worker();
$worker->onWorkerStart = function () {
    $http = new Workerman\Http\Client();

    $http->get('https://example.com/', function ($response) {
        var_dump($response->getStatusCode());
        echo $response->getBody();
    }, function ($exception) {
        echo $exception;
    });

    $http->post('https://example.com/', ['key1' => 'value1', 'key2' => 'value2'], function ($response) {
        var_dump($response->getStatusCode());
        echo $response->getBody();
    }, function ($exception) {
        echo $exception;
    });

    $http->request('https://example.com/', [
        'method' => 'POST',
        'version' => '1.1',
        'headers' => ['Connection' => 'keep-alive'],
        'data' => ['key1' => 'value1', 'key2' => 'value2'],
        'success' => function ($response) {
            echo $response->getBody();
        },
        'error' => function ($exception) {
            echo $exception;
        }
    ]);
};
Worker::runAll();

Flux de retour progressif:

<?php
require_once __DIR__ . '/vendor/autoload.php';

use Workerman\Connection\TcpConnection;
use Workerman\Http\Client;
use Workerman\Protocols\Http\Chunk;
use Workerman\Protocols\Http\Request;
use Workerman\Protocols\Http\Response;
use Workerman\Worker;

$worker = new Worker('http://0.0.0.0:1234');
$worker->onMessage = function (TcpConnection $connection, Request $request) {
    $http = new Client();
    $http->request('https://api.bla.cn/v1/chat/completions', [

            'stream' => true,
            'messages' => [['role' => 'user', 'content' => 'hello']],
        ]),

        //"Content-Type" => "application/octet-stream",
        "Transfer-Encoding" => "chunked",
    ], ' '));
};
Worker::runAll();

Options

<?php
require __DIR__ . '/vendor/autoload.php';
use Workerman\Worker;
$worker = new Worker();
$worker->onWorkerStart = function(){
    $options = [
        'max_conn_per_addr' => 128, // Maximum concurrent connections per domain name
        'keepalive_timeout' => 15,  // Close the connection if no communication occurs for a long time
        'connect_timeout'   => 30,  // Connection timeout
        'timeout'           => 30,  // Timeout for waiting for response after sending a request
    ];
    $http = new Workerman\Http\Client($options);

    $http->get('http://example.com/', function($response){
        var_dump($response->getStatusCode());
        echo $response->getBody();
    }, function($exception){
        echo $exception;
    });
};
Worker::runAll();

Utilisation des coroutines

Remarque
L'utilisation des coroutines nécessite workerman>=5.0, workerman/http-client>=2.0.0 et l'installation de composer require revolt/event-loop ^1.0.0

use Workerman\Worker;

require_once __DIR__ . '/vendor/autoload.php';

$worker = new Worker();
$worker->onWorkerStart = function () {
    $http = new Workerman\Http\Client();

    $response = $http->get('https://example.com/');
    var_dump($response->getStatusCode());
    echo $response->getBody();

    $response = $http->post('https://example.com/', ['key1' => 'value1', 'key2' => 'value2']);
    var_dump($response->getStatusCode());
    echo $response->getBody();

    $response = $http->request('https://example.com/', [
        'method' => 'POST',
        'version' => '1.1',
        'headers' => ['Connection' => 'keep-alive'],
        'data' => ['key1' => 'value1', 'key2' => 'value2'],
    ]);
    echo $response->getBody();
};
Worker::runAll();

Lorsqu'aucune fonction de rappel n'est définie, le client retourne de manière synchrone les résultats de la requête asynchrone, le processus de requête ne bloque pas le processus en cours, ce qui signifie qu'il peut traiter les requêtes de manière concurrente.

Remarque:

1. Le projet doit d'abord charger require __DIR__ . '/vendor/autoload.php';
2. Tout le code asynchrone ne peut être exécuté qu'après le démarrage de workerman
3. Prend en charge tous les projets basés sur le développement de workerman, y compris GatewayWorker, PHPSocket.io, etc.
