# 州

Thordata支持用戶在代理路由中設置`state`參數，通過**指定州級行政區的住宅IP**傳輸，實現精準定位。示例：`country-us-state-alabama`表示從美國亞拉巴馬州獲取代理。

{% endhint %}

{% hint style="danger" %}
必須與`country`參數一起使用`state`參數，單獨使用`state`參數無法獲取指定國家州的IP。
{% endhint %}

以下是一組**國家**和**州**參數的示例組合：

| 国家-州     | 参数                             |
| -------- | ------------------------------ |
| 美國加利福尼亞州 | `country-us-state-california:` |
| 英國英格蘭    | `country-gb-state-england`     |
| 泰國蘇林     | `country-th-state-surin`       |
| 香港九龍城    | `country-hk-state-kowloonc`    |
| 澳大利亞維多利亞 | `country-au-state-victoria`    |

**代碼示例：**

使用來自美國加利福尼亞州的隨機 IP 地址對 `ipinfo.thordata.com` 執行查詢
