sse client

[jeevatkm]

@chrisfeng0723 In resty response, body read fully at once. It is not a stream. Maybe you could try https://pkg.go.dev/github.com/go-resty/resty/v2#Request.SetDoNotParseResponse and handle the body yourself. However, it will not be an actual SSE experience.

I may think of adding an SSE client in the v3.

SSE client would be very appreciated! 🙏

maybe this code can help you

func TestSSE(t *testing.T) {
	// Start the server
	go func() {
		err := http.ListenAndServe(":5000", http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
			w.Header().Set("Content-Type", "text/event-stream")
			w.Header().Set("Cache-Control", "no-cache")
			w.Header().Set("Connection", "keep-alive")
			for i := 0; i < 3; i++ {
				_, err := w.Write([]byte(fmt.Sprintf("%d\n", i)))
				if err != nil {
					t.Log("Error writing SSE event:", err)
					return
				}

				if f, ok := w.(http.Flusher); ok {
					f.Flush()
				}
				time.Sleep(1 * time.Second)
			}
		}))
		if err != nil {
			t.Error(err)
		}
	}()
	time.Sleep(time.Second * 3)

	resp, err := resty.New().
		R().
		SetDoNotParseResponse(true).
		Get("http://localhost:5000")
	if err != nil {
		t.Error(err)
	}
	defer resp.RawResponse.Body.Close()

	scanner := bufio.NewScanner(resp.RawResponse.Body)
	reply := ""
	for scanner.Scan() {
		_res := scanner.Text()
		if _res == "" {
			continue
		}
		reply += _res
		t.Log(_res)
	}

	t.Log(reply)
}
