请问能否改成更加通用的版本？即不光是代理openai，甚至wikipedia，discord等，即用户想要好访问的目标地址，可以作为参数上传？ 这是github copilot给的版本，帮忙看看是否能达到效果？

async function handleRequest(request) {
      const url = new URL(request.url)
      let target = url.searchParams.get('target')

      if (!target) {
        return new Response('Target host is required', { status: 400 })
      }

      target = target.replace(/^https?:\/\//, '')

      const apiUrl = new URL(request.url)
      apiUrl.host = target

      const response = await fetch(modifiedRequest)

      const modifiedResponse = new Response(response.body, response)
      modifiedResponse.headers.set('Access-Control-Allow-Origin', '*')

      return modifiedResponse

addEventListener('fetch', event => {
      event.respondWith(handleRequest(event.request))
