# ngx\_http\_access\_module

* [示例配置](/nginx-docs/he-xin-gong-neng/http/ngx_http_access_module.md#example_configuration)
* [指令](/nginx-docs/he-xin-gong-neng/http/ngx_http_access_module.md#directives)
  * [allow](/nginx-docs/he-xin-gong-neng/http/ngx_http_access_module.md#allow)
  * [deny](/nginx-docs/he-xin-gong-neng/http/ngx_http_access_module.md#deny)

`ngx_http_access_module` 模块允许限制对某些客户端地址的访问。

访问也可以通过[密码](/nginx-docs/he-xin-gong-neng/http/ngx_http_auth_basic_module.md)、[子请求结果](/nginx-docs/he-xin-gong-neng/http/ngx_http_auth_request_module.md)或 [JWT](/nginx-docs/he-xin-gong-neng/http/ngx_http_auth_jwt_module.md) 限制。可用 [satisfy](/nginx-docs/he-xin-gong-neng/http/ngx_http_core_module.md#satisfy) 指令通过地址和密码同时限制访问。

## 示例配置 <a href="#example_configuration" id="example_configuration"></a>

```
location / {
    deny  192.168.1.1;
    allow 192.168.1.0/24;
    allow 10.1.1.0/16;
    allow 2001:0db8::/32;
    deny  all;
}
```

按顺序检查规则，直到找到第一个匹配项。在本例中，仅允许 IPv4 网络 `10.1.1.0/16` 和 `192.168.1.0/24` 与 IPv6 网络 `2001:0db8::/ 32` 访问，不包括地址 `192.168.1.1`。在很多规则的情况下，最好使用 [ngx\_http\_geo\_module](/nginx-docs/he-xin-gong-neng/http/ngx_http_geo_module.md) 模块变量。

## 指令 <a href="#directives" id="directives"></a>

### allow

| -       | 说明                                                 |
| ------- | -------------------------------------------------- |
| **语法**  | **allow** `address` \| `CIDR` \| `unix:` \| `all`; |
| **默认**  | ——                                                 |
| **上下文** | http、server、location、limit\_except                 |

允许访问指定的网络或地址。如果指定了特殊值 `unix:`（1.5.1），则允许访问所有 UNIX 域套接字。

### deny

| -       | 说明                                                |

| **默认**  | ——                                                |
| **上下文** | http、server、location、limit\_except                |

拒绝指定网络或地址的访问。如果指定了特殊值 `unix:`（1.5.1），则拒绝所有 UNIX 域套接字的访问。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docshome.gitbook.io/nginx-docs/he-xin-gong-neng/http/ngx_http_access_module.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
