 5 | 
 6 | **注意**：
 7 | - 该代理只供 [speechgpt.app](https://speechgpt.app) 使用。
 8 | - 不保证稳定性，不保证长期可用，长期使用建议自行部署。

24 | ## 📝 说明
25 | 如何限制只有自己的域名可以访问？
26 | 
27 | ```javascript
28 | const OPENAI_URL = 'https://api.openai.com';
29 | 
30 | addEventListener('fetch', event => {
31 |   event.respondWith(handleRequest(event.request));
32 | });
33 | 
34 | async function handleRequest(request) {
35 |   const origin = request.headers.get('Origin');
36 |   const allowedOrigin = '<允许访问的域名>';
37 | 
38 |   if (origin === allowedOrigin) {
39 |     const url = new URL(request.url);
40 |     url.host = OPENAI_URL.replace(/^https?:\/\//, '');
41 | 
42 |     const modifiedRequest = new Request(url.toString(), {
43 |       headers: request.headers,
44 |       method: request.method,
45 |       body: request.body,
46 |       redirect: 'follow'
47 |     });
48 | 
49 |     const response = await fetch(modifiedRequest);
50 |     const modifiedResponse = new Response(response.body, {
51 |       status: response.status,
52 |       statusText: response.statusText,
53 |       headers: response.headers
54 |     });
55 | 
56 |     modifiedResponse.headers.set('Access-Control-Allow-Origin', allowedOrigin);
57 | 
58 |     return modifiedResponse;
59 |   } else {
60 |     return new Response('Unauthorized', { status: 403 });
61 |   }
62 | }
63 | ```
64 | 将 `<允许访问的域名>` 替换为你自己的域名即可。
