# 发起请求

向以下地址发出请求 `https://ip.oxylabs.io/location` 使用列表中的第一个 ISP 代理。替换 `USERNAME` 和 `PASSWORD` 替换为您的代理用户凭据。&#x20;

{% hint style="info" %}
使用 [**ip.oxylabs.io/location**](https://ip.oxylabs.io/location) 以检查您 IP 的参数——该域从四个地理定位数据库提供信息：MaxMind、IP2Location、DB-IP 和 IPinfo.io。参数包括 IP 地址、提供商、国家、城市、邮编、ASN、组织名称、时区和元信息（数据库披露时）。
{% endhint %}

```sh
curl -x isp.oxylabs.io:8001 -U "user-USERNAME:PASSWORD" https://ip.oxylabs.io/location 
```

请注意，您必须遵循上述构建用户名字符串的示例才能成功发出请求。请使用完全相同的语法，并注意用户名和密码的大小写敏感。

您代理列表中的第一个 IP 将始终使用该`8001` 端口。要使用不同的代理发出请求，您需要找到您的 [**代理列表**](https://developers.oxylabs.io/documentation/cn/dai-li/isp-proxies/proxy-list) 并从中获取端口值。&#x20;
