# 州

Thordata支持用户在代理路由中设置`state`参数，通过**指定州级行政区的住宅IP**传输，实现精准定位。

示例：`country-us-state-alabama`表示从美国亚拉巴马州获取代理。

{% endhint %}

{% hint style="danger" %}
参数必须与`country`参数一起使用，单独使用`state`参数无法获取指定国家州的IP
{% endhint %}

以下是一些**国家**和**州**参数的示例组合：

| 国家-州     | 参数                             |
| -------- | ------------------------------ |
| 美国加利福尼亚州 | `country-us-state-california:` |
| 英国英格兰    | `country-gb-state-england`     |
| 泰国素林     | `country-th-state-surin`       |
| 香港九龙城    | `country-hk-state-kowloonc`    |
| 澳大利亚维多利亚 | `country-au-state-victoria`    |

**代码示例：**

使用来自美国加利福尼亚州的随机IP地址对`ipinfo.thordata.com`执行查询
