nuxt3 后端(server)目录接口调用问题求解答~

server 里面写了两个接口,调用地址分别是/yd/copyByUrl 和/yd/aaa 用 postman 都能调用成功,但是在/yd/copyByUrl 里面调用/yd/aaa 时报错:

copyByUrl 方法
[nuxt] [request error] [unhandled] [500] [GET] "/yd/aaa": <no response> Failed to parse URL from /yd/aaa
  at process.processTicksAndRejections (node:internal/process/task_queues:95:5)

[Vue Router warn]: No match found for location with path "/yd/copyByUrl"
[Vue Router warn]: No match found for location with path "/yd/copyByUrl"
[Vue Router warn]: No match found for location with path "/yd/copyByUrl"

调用的代码: let res = await $fetch('/yd/aaa/')

目前的解决办法是 gpt 给的:

const req = event.req;
  const protocol = req.headers['x-forwarded-proto'] || 'http';
  const host = req.headers.host;
  const baseUrl = `${protocol}://${host}`;

  console.log("Base URL:", baseUrl);

通过拼接 baseUrl 和路径来实现调用的

请问,nuxt3 在遇到这种需要互相调用的接口下,是该怎么写接口呢? 闲鱼问了三个人都没给解决...说没遇到过
