限制与 Guzzle HTTP PHP 客户端的连接时间
我正在使用Guzzle打开url-s列表并获取标题。有些网址需要很长时间才能响应,无法打开,我想忽略它们。在Guzzle抛出异常之前,我需要长达20多秒的时间,我想改变这一点并将连接时间限制为2秒。我有这个代码,但它仍然需要更长的时间:
<?php
include 'vendor/autoload.php';
$start = new \DateTime("now");
$start = $start->format("d.m.Y H:i:s");
echo $start."\n";
$client = new Guzzle\Http\Client();
Guzzle\Http\StaticClient::mount();
try {
$request = $client->get('http://takestoolongexample', [], ['connect_timeout' => 2, 'timeout' => 3, 'debug' => true]);
$response = $request->send();
var_dump($response->getStatusCode());
} catch (Exception $e) {
echo "\n".$e->getMessage()."\n";
}
$end = new \DateTime("now");
$end = $end->format("d.m.Y H:i:s");
echo "\n".$end."\n";
?>
下面是一个示例结果。如您所见,它花了13秒钟。
$ php test.php

(http://takestoolongexample
是一个真正的网址,在这里改变了它)
