http.createServer((request, response) => {  response.setHeader('Access-Control-Allow-Origin','*')  request.on('data', data => {    console.log(data)  })  request.on('end', () => {    console.log(request)    response.end('success')  })}).listen(8088)在請(qǐng)求的時(shí)候，如果傳參為String類型的，可以成功，但是如果請(qǐng)求Object類型的，就報(bào)錯(cuò)：Request header field Content-Type is not allowed by Access-Control-Allow-Headers in preflight response.請(qǐng)問(wèn)我應(yīng)該怎么寫(xiě)啊
