[akka-user][deprecated] Re: [akka-user] Re: akka-http web socket issue

[vauldex . eblangga]

I will re-open this issue because I am having problems regarding 
`s2.ripple.com`'s reply. 


I was able to connect using either `webSocketClientFlow` and 
`singleWebSocketRequest`.


Having code block as my outgoing message:

```
val outgoing: Source[TextMessage.Streamed, NotUsed] =
  Source.single(TextMessage.Streamed(Source(List("""{"command": 
"subscribe", "stream": "transactions"}"""
```

I was expecting a `TextMessage.Streamed` reply but it replied a 
`TextMessage.Strict` message, naturally this command `{"command": 
"subscribe", "stream": "transactions"}` when sent to `s2.ripple.com` would 
return a stream of data, but it only replies a single message after message 
is sent.

Thanks in advance and God bless.

Yes it works. What's wrong about Streamed?
That's a feature that it's streaming the data – consume it using the
dataBytes contained in the Streamed message.

[akka-user] Re: akka-http web socket issue

[Eric Swenson]

Thanks, Giovanni. That was precisely the problem and while I didn't see the 
article you quoted, I "fixed" the problem on my end by having my client use 
a Source.fromFuture of a promise which I didn't complete.  I'll switch to 
using the approach in the article you referenced.  Still, I think there 
will be lots of people who may use the web socket client in the 
documentation as a starting point. They will expect that the client will 
continue to display messages received from the service while the client is 
running.  I think the example should either a) document that the client 
closes after processing a single message and how to make it maintain the 
web socket connection open, or better, in my opinion, b) use Source.maybe 
to ensure the connection doesn't close.

On a related note, if the web socket server side is implemented using 
akka-http, the example still closes the connection after 1 minute due to 
the server side's not having gotten any TCP packets over the connection. 
The documentation should either a) include a description of how to change 
this timeout or b) have the client include heartbeat logic to keep the 
connection alive.

Are you keeping the outbound client flow open?

[akka-user] Re: akka-http web socket issue

[Eric Swenson]

I wrote a simple python client:

$ cat ws-test.py
import os
from websocket import create_connection

eiid=os.getenv("EIID")
token=os.getenv("BEARER_TOKEN")
header="Authorization: Bearer %s" % token
ws = create_connection("ws://localhost:9000/ws-connect/%s" % eiid, 
header=[header])
while True:
x = ws.recv()
print(x)

And used it with my server.  It does not disconnect and correctly responds to 
all messages sent by the server.  So that rules out problems with the 
akka-http-based server.  it would appear that the issue is with the akka-http 
client (whose code I got from this web page:

> http://doc.akka.io/docs/akka/2.4.7/scala/http/client-side/websocket-support.html#websocketclientflow

Is there some reason why this code does not work?  As mentioned previously, the 
code connects, retrieves and displays one message sent by the server just after 
connection, and then promptly disconnects the websocket connection.

Are there known issues with client-side web socket support in 2.4.7?
