Cloudflare Worker 中转

使用 Cloudflare Worker 实现中转

参考 “不做了睡觉” 的教程

workers 配置文件

  const TELEGRAPH_URL = 'https://api.openai.com';
addEventListener('fetch', (event) => {
  event.respondWith(handleRequest(event.request));
});
async function handleRequest(request) {
  // 安全校验
  if (request.headers.get('auth') !== 'auth_code') {
    return new Response('UnAuthorization', { status: 403 });
  }
  const url = new URL(request.url);
  url.host = TELEGRAPH_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);
  // 添加允许跨域访问的响应头
  modifiedResponse.headers.set('Access-Control-Allow-Origin', '*');
  return modifiedResponse;
}
  

修改 FastGPT 的环境变量

务必别忘了填 v1！

  OPENAI_BASE_URL=https://xxxxxx/v1
OPENAI_BASE_URL_AUTH=auth_code
