我正在使用Guzzle打开url-s列表并获取标题.一些网址花了太长时间才响应,无法打开,我想忽略它们.在Guzzle抛出异常之前,我需要20秒才能完成此操作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";
?>

这是一个示例结果.如你所见,花了13秒.

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

这是Guzzle版本(Guzzle 4)针对此问题的更新解决方案.
$request = $client->get(sprintf("%s/noisesize.api", $this->noiseConfig->url), [
'timeout' => 5, // Response timeout
'connect_timeout' => 5, // Connection timeout
]);

抛出 Guzzle\Http\Exception\RequestException
最新版本的文档在这里:Guzzle请求选项 - connect_timeout,timeout.
精度很小,您还可以在Client构造函数上定义超时
$client = new Guzzle\Http\Client('', array(
'request.options' => array (
'timeout' => 6,
'connect_timeout' => 6
)
));

它对从此客户端发出的所有请求都有效
我知道如何在 Guzzle 中做到这一点的唯一方法是:
$params = array(
'command.request_options' = array(
'timeout' => 5,
'connect_timeout' => 2
)
);
$client = new Client();
$description = ServiceDescription::factory('/path/to/service/description/file');
$client->setDescription($description);
$command = $client->getCommand('commandName', $params);
$command->prepare();
$client->execute($command);

乍一看,Guzzle 的文档似乎非常好,但我认为它很差、混乱且不完整。因此,对我来说,很难弄清楚你的代码是否真的正确以及它是否应该工作。
