php curl多次请求返回慢与curl自身域名DNS转换有关,修改成IP请求正常
php-curl请求接口一般都会碰到的问题,记录一下;
请求域名对应host添加到请求头中
<?php
$host = gethostbyname('kingcard.dgunicom.com');
curl_setopt($ch, CRULOPT_HTTPHEADER, ['Host: '.$host]);
?>
$ch = curl_init(); // curl_setopt($ch, CURLOPT_URL, 'https://kingcard.dgunicom.com/dgZop/api/numSelect'); curl_setopt($ch, CURLOPT_URL, 'https://211.95.193.53/dgZop/api/numSelect'); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false); curl_setopt($ch, CURLOPT_POSTFIELDS, $json); $headers = array(); $headers[] = 'Host: kingcard.dgunicom.com'; $headers[] = 'Content-Type: application/json'; $headers[] = 'Expect:'; curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); $result = curl_exec($ch); if (curl_errno($ch)) { echo 'Error:' . curl_error($ch); } curl_close($ch); echo $result;
