会话控制
了解更多关于 Oxylabs 移动代理的会话控制以及如何延长粘性会话。
建立会话
session ID 参数允许您保持相同的 IP 地址以运行多个请求。要多次重用相同的 IP，请使用 sessid 参数在 用户名 之后与随机创建的字母数字字符串，例如， sessid-abcde12345.
标准会话时间为 10 分钟或最多 60 秒的不活动（无请求）。之后，会自动分配新的 IP 地址。如需调整期望的会话时间，请参阅 会话时长.
例如，您最初的查询带有 sessid-abcde12345 分配的代理 IP 地址 1.1.1.1. 只要您继续用相同的 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，系统将分配新的代理 IP。您下一次使用 sessid-abcde12345 的查询将通过不同的 IP 地址路由，例如 1.1.1.2.
凭证示例列表：
示例表示建立不同会话的凭证列表。
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，我们在第一个请求中在用户名中使用了德国 IP 和 sessid-abcde12345 。所有后续请求将继续使用相同的德国 IP 进行后续查询：

puts result.body会话时长
该 sesstime parameter 与 sessid一起使用，允许您将会话延长到超过 10 分钟或为其设置特定时间。
您可以使用 sesstime 参数设置为 将相同的 IP 保持最长 1440 分钟 （24 小时）。
但是，由于移动代理池是动态的，您的连接可能会更早结束。如果发生这种情况，请使用新的 session 参数开始会话。
会话时间参数并不能确保您所有的查询都在会话结束前完成。即使请求尚未完成，会话也会在设置的时间限制内到期。
凭证示例列表：
示例表示一组凭证，这些凭证建立不同会话并具有不同的会话时间（分钟）。
