How I can ping server? #87

Closed Vlada31R closed 4 years ago

Vlada31R commented 4 years ago

Hi, help me please. Using socketClient.socket?.send("\n") fails. I need to ping the server because I get "Stream and encountered" error, even after setting heart-beat.

WrathChaos commented 4 years ago

Hello @Vlada31R, You cannot directly ping the server with this library but of course, you can use the connection methods to get the ping from server. I believe that you don't need to ping the server for your use-case, you have the Steam and encountered error only.

Did you check these issues?

Also, I'm planning to add the ping the server functionality soon.

Vlada31R commented 4 years ago

Hi, thank you for quick response. Yeah, I checked the issues. There are several possible solutions were mentioned:

  1. I can add heart-beat header - I did it, but it didn't help
  2. Put a timer for every 30s to send a ping command to server - but I have a question how to do it
  3. there also was solution to call openSocketWithURLRequest with timer for every 20 seconds - but I think that it's not very good idea to open connection each 20 sec, reconnection sounds better, but I also faced some troubles while trying to reconnect
  4. As for this point "control the stompclient connection when changing the new ViewController or any kinds of stuff" - I am using a singleton instance of a web sockets controller
  5. I also believe that it's not server problem because web client works okay That's why I decided to ping server directly. Maybe you have other ideas?

@WrathChaos and maybe there are other opportunities to ping server with your library?

WrathChaos commented 4 years ago

Hello @Vlada31R, Sorry for the late response. Actually you can fork the library and open a PR to finish this one: https://github.com/WrathChaos/StompClientLib/pull/25 Then we can fix the ping server problem at all. Really sorry but I have literally no time to integrate this logic and test it. I'm always open to any contribution. If you have time, please complete this PR :) I'm happy to merge it.

Hi, I see, thank you.

WrathChaos commented 4 years ago

I will try to add this feature in this weekend but I cannot promise you @Vlada31R

Vlada31R commented 4 years ago

Okay, thanks, I will try to do it. And I have one more assumption about the reason of "Stream and encountered" error. Could it be caused by using wss protocol? Thank you in advance!

WrathChaos commented 4 years ago

@Vlada31R, Library itself uses the Facebook's SocketRocket which means it uses a WebSocket. Therefore, you have to use wss protocol. Honestly, I have no idea if you can use it without wss protocol or not.

I see, thank you very much!
