Workerman/HTTP-Client

Beschreibung

Workerman/HTTP-Client ist ein asynchroner HTTP-Client-Komponent. Alle Anfragen und Antworten sind asynchron und nicht blockierend, mit eingebautem Verbindungspool. Die Anfragen und Antworten entsprechen dem PSR7-Standard.

Installation

composer require workerman/http-client

Beispiel

Verwendung von GET- und POST-Anfragen

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();

Datei hochladen

<?php
use Workerman\Worker;

require_once 'vendor/autoload.php';

$worker = new Worker();
$worker->onWorkerStart = function () {
    $http = new Workerman\Http\Client();
    // Datei hochladen
    $multipart = new \Workerman\Psr7\MultipartStream([
        [
            'name' => 'file',
            'contents' => fopen(__FILE__, 'r')
        ],
        [
            'name' => 'json',
            'contents' => json_encode(['a'=>1, 'b'=>2])
        ]
    ]);
    $boundary = $multipart->getBoundary();
    $http->request('http://127.0.0.1:8787', [
        'method' => 'POST',
        'version' => '1.1',
        'headers' => ['Connection' => 'keep-alive', 'Content-Type' => "multipart/form-data; boundary=$boundary"],
        'data' => $multipart,
        'success' => function ($response) {
            echo $response->getBody();
        },
        'error' => function ($exception) {
            echo $exception;
        }
    ]);
};

Worker::runAll();

Fortgeschrittene Streaming-Rückgabe

<?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();
    $http->request('https://api.bla.cn/v1/chat/completions', [
        'method' => 'POST',
        'data' => json_encode([
            'model' => 'gpt-3.5-turbo',
            'temperature' => 1,
            'stream' => true,
            'messages' => [['role' => 'user', 'content' => 'hello']],
        ]),
        'headers' => [
            'Content-Type' => 'application/json',
            'Authorization' => 'Bearer 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',
        ],
        'progress' => function($buffer) use ($connection) {
            $connection->send(new Chunk($buffer));
        },
        'success' => function($response) use ($connection) {
            $connection->send(new Chunk(''));
        },
    ]);
    $connection->send(new Response(200, [
        //"Content-Type" => "application/octet-stream",
        "Transfer-Encoding" => "chunked",
    ], ' '));
};
Worker::runAll();

Optionen

<?php
require __DIR__ . '/vendor/autoload.php';
use Workerman\Worker;
$worker = new Worker();
$worker->onWorkerStart = function(){
    $options = [
        'max_conn_per_addr' => 128, // Maximale Anzahl gleichzeitiger Verbindungen pro Domain
        'keepalive_timeout' => 15,  // Zeitdauer ohne Kommunikation vor dem Schließen der Verbindung
        'connect_timeout'   => 30,  // Verbindungs-Timeout
        'timeout'           => 30,  // Wartezeit auf Antwort nach dem Senden der Anfrage
    ];
    $http = new Workerman\Http\Client($options);

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

Verwendung von Coroutine

Hinweis
Die Verwendung von Coroutine erfordert workerman>=5.0, workerman/http-client>=2.0.0 und die Installation von 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();

Wenn keine Rückruffunktionen festgelegt sind, gibt der Client das Ergebnis der asynchronen Anfrage synchron zurück, ohne den aktuellen Prozess zu blockieren, was bedeutet, dass Anfragen parallel verarbeitet werden können.

Beachten:

1. Das Projekt muss zunächst require __DIR__ . '/vendor/autoload.php'; laden.
2. Alle asynchronen Codes können nur in der laufenden Umgebung nach dem Start von Workerman ausgeführt werden.
3. Es werden alle Projekte unterstützt, die auf Workerman basieren, einschließlich GatewayWorker, PHPSocket.io und anderen.
