如果服务器访问不到 OpenAI，可以考虑使用 Cloudflare Worker 搭建一个代理，并绑定自己的域名。
const OPENAI_URL = 'https://api.openai.com';
addEventListener('fetch', event => {
event.respondWith(handleRequest(event.request))
})
async function handleRequest(request) {
const url = new URL(request.url);
url.host = OPENAI_URL.replace(/^https?:\/\//, '');
const modifiedRequest = new Request(url.toString(), {
headers: request.headers,
method: request.method,
body: request.body,
redirect: 'follow'
});
const response = await fetch(modifiedRequest);
const modifiedResponse = new Response(response.body, response);
modifiedResponse.headers.set('Access-Control-Allow-Origin', '*');
return modifiedResponse;
}
