Timeout bug

[happy-berry]

        var req = HttpRequest.NewRequest().SetTimeout(time.Second * 5).SetHeaders(map[string]string{"Content-Type": "application/json"})
    req.SetTimeout(time.Second * 3)
    fmt.Println(req)
    res, err := req.Post("http://127.0.0.1:8080/mock/Send/timeout", nil)

I saw the attribute timeout unable to take effect, It only has the dafault 30s . when initiating a post request, a new request object will be created instead of using the original request object to initiate the request
