利用deno代理cloudflare ai gateway#

上一篇文章介绍了如何使用cloudflare ai gateway，但是由于cloudflare ai gateway会透传用户的ip，所以有些地区原本无法访问的ai api还是会无法访问，这时候我们可以使用deno来代理cloudflare ai gateway，这样就可以解决地区限制的问题。

代码#

1
const TARGET_HOST = "gateway.ai.cloudflare.com";
2
const BASE_PATH = "/v1/你自己的标识符/aigate/google-ai-studio";
3

4
Deno.serve(async (request) => {
5
  const url = new URL(request.url);
6
  const originalPath = url.pathname;
7

8
  url.host = TARGET_HOST;
9
  url.pathname = BASE_PATH + originalPath;
10
  url.protocol = "https:";
11

12
  const newRequest = new Request(url.toString(), {
13
    headers: request.headers,
14
    method: request.method,
15
    body: request.body,
16
    redirect: "follow",
17
  });
18

19
  const response = await fetch(newRequest);
20

21
  // 添加 CORS 头
22
  const headers = new Headers(response.headers);
23
  headers.set("Access-Control-Allow-Origin", "*");
24
  headers.set("Access-Control-Allow-Methods", "*");
25
  headers.set("Access-Control-Allow-Headers", "*");
26

27
  return new Response(response.body, {
28
    status: response.status,
29
    headers: headers,
30
  });
31
});
