+title: HTTP 代理中转
+description: 使用 HTTP 代理实现中转
+---
+
+如果你有代理工具（例如 [Clash](https://github.com/Dreamacro/clash) 或者 [sing-box](https://github.com/SagerNet/sing-box)），也可以使用 HTTP 代理来访问 OpenAI。只需要添加以下两个环境变量即可：
+
+```bash
+AXIOS_PROXY_HOST=
+AXIOS_PROXY_PORT=
+```
+
+以 Clash 为例，建议指定 `api.openai.com` 走代理，其他请求都直连。示例配置如下：
+
+```yaml
+mixed-port: 7890
+allow-lan: false
+bind-address: '*'
+mode: rule
+log-level: warning
+dns:  
+  enable: true  
+  ipv6: false  
+  nameserver:  
+    - 8.8.8.8
+    - 8.8.4.4 
+  cache-size: 400
+proxies:
+    - 
+proxy-groups:
+  - { name: '♻️ 自动选择', type: url-test,  proxies: [香港V01×1.5], url: 'https://api.openai.com', interval: 3600}
+rules:
+  - 'DOMAIN-SUFFIX,api.openai.com,♻️ 自动选择'
+  - 'MATCH,DIRECT'
+```
+
+然后给 FastGPT 添加两个环境变量：
+
+```bash
+AXIOS_PROXY_HOST=127.0.0.1
+AXIOS_PROXY_PORT=7890
+```
+
