Go 已被 CORS 策略阻止：Response to preflight request doesn’t pass access control check

我已经创建了旅行服务器.它工作得很好，我们可以通过Inslenia发出POST个请求，但是当我们在前端通过AXIOS发出POST个请求时，它会发送一个错误:

已被CORS策略阻止:对印前判断请求的响应未通过访问控制判断:它没有HTTP OK状态.

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)
   });
} 

我的围棋档案:

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, Accept-Encoding, X-CSRF-Token, Authorization")
}


func WithUserAgent(base http.Handler) http.Handler {
    return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {

    ctx := r.Context()
    ua := r.Header.Get("Jwt")
    ctx = context.WithValue(ctx, "jwt", ua)

    r = r.WithContext(ctx)

    setupResponse(&w, r)
     base.ServeHTTP(w, r)
  })
}

const (
    host     = "localhost"
    port     = 5432
    user     = "postgres"
    password = "postgres"
    dbname   = "postgres"
)

func main() {

    psqlInfo := fmt.Sprintf("host=%s port=%d user=%s "+
           "password=%s dbname=%s sslmode=disable",
               host, port, user, password, dbname)

    server := &s.Server{psqlInfo}

    twirpHandler := p.NewFinanceServiceServer(server, nil)

    wrap := WithUserAgent(twirpHandler)
      log.Fatalln(http.ListenAndServe(":9707", wrap))
}

正如我之前在失眠中说过的那样，它工作得很好，但是当我们发出axios POST请求时，在浏览器的控制台上会出现以下内容:
