# 会话控制与 IP 轮换

了解如何管理住宅代理会话，以便在多个请求中保持相同的 IP 地址，并控制会话时长和 IP 轮换。

Oxylabs 住宅代理默认会在每次请求时自动轮换。要为连续请求保持相同的 IP 地址，请在用户名字符串中配置粘性会话参数，或通过粘性代理入口端口连接。

<table><thead><tr><th width="156">方法</th><th width="132">参数</th><th>说明</th></tr></thead><tbody><tr><td><a href="#default-sticky-sessions-sessid"><strong>粘性会话</strong></a></td><td><code>sessid</code></td><td>自动轮换到新的 IP 以保持会话活跃。10 分钟（默认）。</td></tr><tr><td><a href="#extend-session-duration-sesstime"><strong>会话持续时间</strong></a></td><td><code>sesstime</code></td><td>延长 <code>sessid</code> 有效期。计时器到期后会话结束。最长 1440 分钟（24 小时）</td></tr><tr><td><a href="#single-ip-strict-session-binding-sessid_oneip"><strong>单 IP 绑定</strong></a></td><td><code>sessid_oneip</code></td><td>严格绑定到单个出口节点。若 IP 掉线，将以 HTTP <code>502</code> 错误失败。最长 1440 分钟（24 小时）</td></tr><tr><td><a href="#sticky-proxy-entry-nodes-port-range"><strong>粘性端口</strong></a></td><td>端口范围</td><td>基于端口的粘性（端口 <code>10001–49999</code>）无需基于用户名的参数。最长 10 分钟。</td></tr></tbody></table>

## 默认粘性会话（`sessid`)

该 `sessid` 该参数会在 IP 在线时将多个请求路由到同一 IP 地址。将 `sessid` 在你的 `用户名` 后附加一个随机字母数字字符串（例如 `sessid-abcd1234`):

```
customer-USERNAME-cc-DE-sessid-abcd1234:PASSWORD
```

默认情况下，会话持续 10 分钟，或者在 60 秒内没有任何请求后结束——以先到者为准。一旦发生这种情况，系统会自动分配一个新的 IP 地址，以便你的请求不中断。要更改会话时长，请参阅 [延长会话持续时间](#extend-session-duration-sesstime).

## 延长会话持续时间（`sesstime`)

将 `sesstime` 参数与 `sessid` 结合使用，可将会话持续时间从 10 分钟默认值（或最长 60 秒无活动）延长至最多 1440 分钟（24 小时）。以分钟为单位指定时长（例如， `sesstime-30` 表示 30 分钟）：

```
customer-USERNAME-cc-DE-sessid-abcd1234-sesstime-30:PASSWORD
```

{% hint style="info" %}
**注意：** 会话时长参数不能保证所有请求都在会话结束前完成。即使部分请求仍在进行中，只要达到时间限制，会话就会过期。
{% endhint %}

{% hint style="warning" %}
由于住宅代理 IP 可用性是动态的，单个出口节点可能会在你指定的会话时间到期前断开。如果出口节点掉线， `sessid` 将自动轮换到新的 IP 以完成你的请求。&#x20;
{% endhint %}

#### 代码示例

我们沿用前一个示例中的同一个德国 IP，这次我们添加 `sessid` 字符串和 `sesstime` 参数，持续 7 分钟：

## 单 IP 会话绑定（`sessid_oneip`)

使用 `sessid_oneip` 而不是 `sessid` 当你的工作流需要严格的 IP 一致性且无法容忍会话中途 IP 轮换时。&#x20;

与标准粘性会话不同，如果分配的出口节点离线，系统不会轮换到新 IP，而是请求以 HTTP `502 Bad Gateway` 错误失败。当 `502` 发生时，请使用新的 `sessid_oneip` 字符串启动新会话。 `sessid_oneip` 可与 `sesstime` 以与 `sessid`.

## 粘性代理入口节点（端口范围）

连接到特定国家/地区的入口节点点位，使用专用端口范围（`10001–49999`）即可在不传递 `sessid` 用户名字符串中的参数的情况下，将 IP 地址保持最长 10 分钟。重复使用同一端口可保持相同的出口节点，而更改端口会分配一个新的粘性 IP。

{% hint style="info" %}
特定国家/地区的粘性入口端口支持标准用户名/密码和 IP 白名单认证，但不支持城市或州级参数。&#x20;
{% endhint %}

请参阅 [**Oxylabs 仪表板**](https://dashboard.oxylabs.io/en/) 以获取入口点信息，下载完整的粘性入口点列表，或在下表中查看它们。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://developers.oxylabs.io/products/cn/proxies/residential-proxies/session-control.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
