会话控制

添加 sessid 参数及会话 ID 字符串，例如，sessid-abc12345，启用会话控制。以下请求不改变代理。以下示例显示了会话控制的工作方式：

• 您在 sessid-random123 的初始查询得到了代理 IP 地址 1.1.1.1

• 只要您一直在使用相同的会话 ID 发送新请求，系统就会将您的查询通过 1.1.1.1 路由

代码示例

第一个请求将选择德国 IP，后续的新查询保持相同的 IP（会话控制）：

cURL

curl -x dc.de-pr.oxylabs.io:40000 -U "customer-USERNAME-sessid-abcde12345:PASSWORD" https://ip.oxylabs.io/location

PHP

<?php
$username = 'USERNAME';
$password = 'PASSWORD';
$session = mt_rand();
$proxy = 'dc.de-pr.oxylabs.io:40000';
$query = curl_init('https://ip.oxylabs.io/location');
curl_setopt($query, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($query, CURLOPT_PROXY, "http://$proxy");
curl_setopt($query, CURLOPT_PROXYUSERPWD, "customer-$username-sessid-$session:$password");
$output = curl_exec($query);
curl_close($query);
if ($output)
    echo $output;
?>
