我已经创建了旅行服务器。它工作正常，我们可以POST通过Insomnia 发出请求，但是当我们POST在前端通过axios 发出请求时，它将发送错误：

我们对axios的要求：

let config = {
headers: {
  "Content-Type": "application/json",
  'Access-Control-Allow-Origin': '*',
  }
}

let data = {
  "id": 4
 }

 axios.post('http://196.121.147.69:9777/twirp/route.FRoute/GetLists', data, config)
   .then((res) => {
      console.log(res)
     })
    .catch((err) => {
      console.log(err)
   });
} 

我的文件：

func setupResponse(w *http.ResponseWriter, req *http.Request) {
    (*w).Header().Set("Access-Control-Allow-Origin", "*")
    (*w).Header().Set("Access-Control-Allow-Methods", "POST,GET,OPTIONS, PUT, DELETE")

    (*w).Header().Set("Access-Control-Allow-Headers", "Accept, Content-Type, Content-Length, …
