会话控制

了解如何管理 session ID 参数，该参数允许您在多次请求中保持相同的 IP 地址。

建立会话

session ID 参数允许您使用相同的 IP 地址运行多次请求。要多次重用相同的 IP，请在 sessid 参数后使用 username 并附加随机生成的字母数字字符串，例如， sessid-abcd1234.

标准会话时间为 10 分钟，或者最多 60 秒不活动（无请求）。之后，会自动分配新的 IP 地址。要调整所需的会话时间，请参阅 会话时间.

例如，您首次使用 sessid-abcd1234 分配的代理 IP 地址 1.1.1.1. 只要您继续使用相同的 session ID 发送新请求且该 IP 地址在线且可用，系统就会通过 1.1.1.1. 如果您停止发送请求 60 秒或该 IP 地址不再在线，系统会分配新的代理 IP。您下一次使用 sessid-abcd1234 的查询将通过不同的 IP 地址路由，例如 1.1.1.2.

凭据列表示例：

该示例表示一组用于建立不同会话的凭据列表。

customer-USERNAME-sessid-iqwcp:PASSWORD
customer-USERNAME-sessid-tevab:PASSWORD
customer-USERNAME-sessid-6drwn:PASSWORD
customer-USERNAME-sessid-7eh7g:PASSWORD
customer-USERNAME-sessid-z7cao:PASSWORD

代码示例

在此示例中，我们在第一次请求的 username 中使用德国 IP 和 sessid-abcd1234 。所有后续请求在进一步查询时将保持相同的德国 IP：

curl -x pr.oxylabs.io:7777 -U "customer-USERNAME-cc-DE-sessid-abcd1234:PASSWORD" https://ip.oxylabs.io/location

<?php
$username = 'USERNAME';
$password = 'PASSWORD';
$country = 'DE';
$session = mt_rand();
$proxy = 'pr.oxylabs.io:7777';
$query = curl_init('https://ip.oxylabs.io/location');
curl_setopt($query, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($query, CURLOPT_PROXY, "http://$proxy");
curl_setopt($query, CURLOPT_PROXYUSERPWD, "customer-$username-cc-$country-sessid-$session:$password");
$output = curl_exec($query);
curl_close($query);
if ($output)
    echo $output;
?>

会话时间

该 sesstime 参数与 sessid一起使用，允许您将会话时间延长超过 10 分钟或为其设置特定时间。

您可以使用 sesstime 参数来 将相同 IP 保持最多 1440 分钟 （24 小时）。然而，由于住宅代理池是动态的，您的连接可能会提前结束。如果发生这种情况，请使用新的 session 参数重新启动会话。

会话时间参数并不保证您的所有查询会在会话结束前完成。会话将在设定的时间限制内过期，即使请求尚未完成。

凭据列表示例：

示例表示一组凭据，这些凭据用于建立具有不同会话时长（分钟）的不同会话。

customer-USERNAME-sessid-iqwcp-sesstime-5:PASSWORD

customer-USERNAME-sessid-7eh7g-sesstime-60:PASSWORD
