# 地理位置定位

您可以指定访问目标网站的国家、城市或美国的州府。

### 国家定向

您可以通过在代理凭证的密码后添加`_country-`来启用国家级定向。

美国的使用示例：

```
curl -k -v -x http://unblocker.iproyal.com:12323 --proxy-user user:password_country-us -L https://ipv4.icanhazip.com
```

该参数的值为两位字母的国家/地区代码（采用[ISO 3166-1 alpha-2格式](https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2)）。

您可以同时设置多个国家。

### 城市定向

对于城市级定向，请在代理凭证的密码后添加`_city-`键，其值应为城市名称。

{% hint style="info" %}
注意：当定向特定城市时，必须先使用“\_country-”键指定国家，因为多个国家可能存在同名城市。
{% endhint %}

示例：

```
curl -k -v -x http://unblocker.iproyal.com:12323 --proxy-user user:password_country-us_city-chicago -L https://ipv4.icanhazip.com
```

### 州府定向

此功能仅支持美国的州府定向。若要定向特定州府，请在代理凭证的密码后添加`_state-`键，其值应为州府名称。

示例：

```
curl -k -v -x http://unblocker.iproyal.com:12323 --proxy-user user:password_country-us_state-iowa -L https://ipv4.icanhazip.com
```
