Large files cannot be downloaded in api service.

[jayecc]

Describe the bug go-zero api cannot realize file stream download when downloading large files ?

1、go http server

func main()  {
	http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
		w.Header().Set("Content-Type", "application/octet-stream")
		w.Header().Set("Content-Disposition", "attachment; filename=demo.csv")
		w.Header().Set("Content-Transfer-Encoding", "binary")
		wr := csv.NewWriter(w)
		for i := 0; i < 5e10; i++ {
			wr.Write([]string{strconv.Itoa(i), time.Now().String()})
			wr.Flush()
		}
	})
	http.ListenAndServe(":8888",nil)
}

2、go-zero server

func templateHandler(svcCtx *svc.ServiceContext) http.HandlerFunc {
	return func(w http.ResponseWriter, r *http.Request) {
		w.Header().Set("Content-Type", "application/octet-stream")
		w.Header().Set("Content-Disposition", "attachment; filename=demo.csv")
		w.Header().Set("Content-Transfer-Encoding", "binary")
		wr := csv.NewWriter(w)
		for i := 0; i < 5e10; i++ {
			wr.Write([]string{strconv.Itoa(i), time.Now().String()})
			wr.Flush()
		}
	}
}

Environments (please complete the following information):

• OS: darwin/amd64
• go-zero version 1.3.3

check your Timeout settings.

[jayecc]

An infinite timeout has been reached, unable to implement streaming mode. It only works for large file downloads.
