# 排除国家
了解如何在 DataImpulse 代理中使用 exclude-country 参数，从代理池中筛选掉特定国家，以实现更有针对性的 IP 选择。
`nocr` 当选择“所有国家”时，可从代理配置中排除特定国家。
如果您想排除 **Germany** 作为国家，您的代码将如下所示：
curl -x "http://login__nocr.de:password@gw.dataimpulse.com:823" https://api.ipify.org/

# Agent Instructions

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://docs.dataimpulse.com/dataimpulse-documentation-zh-cn/dai-li/can-shu/pai-chu-guo-jia.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
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.
