如何使用curl php检查REST API是否已关闭

How can I check if RESTAPI is down using curl php

我想创建一个虚拟环境来检查Web服务是否关闭。

案例：如果Web服务关闭7秒，那么系统应该重试一次，如果不工作，那么它应该将通知发送给管理员。

$ch = curl_init();
curl_setopt($ch, CURLOPT_FAILONERROR, true);
curl_setopt($ch, CURLOPT_URL, $url);
// Use 0 to wait indefinitely.
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 7);
// The maximum number of seconds to allow cURL functions to execute
curl_setopt($ch, CURLOPT_TIMEOUT, 7);
curl_setopt($ch, CURLOPT_HEADER, FALSE);
//curl_setopt($ch, CURLOPT_NOBODY, TRUE); // remove body
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$responseData = curl_exec($ch);

$curl_errno = curl_errno($ch);
$curl_error = curl_error($ch);
$httpCode = curl_getinfo($ch);
curl_close($ch);

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_NOBODY, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_exec($ch);
$retcode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
if ($retcode == 200)
{
// It's working
}
else
{
// It's down
}

最后，我找到了解决办法。

$ch = curl_init();
curl_setopt($ch, CURLOPT_FAILONERROR, true);
curl_setopt($ch, CURLOPT_URL, $url);
// Use 0 to wait indefinitely.
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 7);
// The maximum number of seconds to allow cURL functions to execute
curl_setopt($ch, CURLOPT_TIMEOUT, 7);
curl_setopt($ch, CURLOPT_HEADER, FALSE);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$responseData = curl_exec($ch);

$curl_errno = curl_errno($ch);
$curl_error = curl_error($ch);
$httpCode = curl_getinfo($ch);
curl_close($ch);

if ($curl_errno > 0){
if($loop > 1 ){
//send mail to admin
}else{
$loop++;
sleep(7);
checkData();
}
}
}
checkData();
