First off, thank you for the awesome library.

I was wondering if is possible to run this command without user input. Personally, I just want to connect to a websocket, see it's initial message, and then exit.

Could you please help with the below issue. I am not able to connect.
Thanks

wsd -url=ws://localhost:1337/ws

I installed go and then I downloaded the go-get using go get github.com/alexanderGugel/wsd but when I run wsd it says command not found.

Bug report

What is the current behavior?
Hi, it took a few months to debug the adb in android gives me problems. I connect the device, accept the debugging authorization and every 20 minutes it disconnects alone, thus popping up again to accept authorization. I debug the apps with livereload, I use the ionic 4 framework. Does anyone know why that happens? Some time ago this was working correctly but I don't know if it's an adb problem or not.

If the current behavior is a bug, please provide the steps to reproduce.

I use the Ionic Framework with version 4, but this happens to me with any version,
1. I connect my device to the PC.

2. I accept the authorization of debugging.

3. I check with the adb devices command that my device recognizes.

4. You recognize it.

5. I launch my application with the command:
ionic cordova run android --livereload --consolelogs.

6. I open the chrome bug to debug my app and see the logs.

7. When 20 minutes have passed, the authorization popup reappears on the device and I get the following error in the DevTools console

Error por consola:

[WDS] Disconnected!
close @ vendor.js:137905

Failed to load resource: net::ERR_CONNECTION_REFUSED
sockjs-node/info?t=1590993683214

What is the expected behavior?

Just months ago or last year this didn't happen. I did not give this error every 20 minutes.

wsd -url="wss://loggregator.128.107.36.242.xip.io:4443" -k

Is there any support for flags ?

Attempting to use WSD with an endpoint that returns an HTTP 400 Bad Request results in a segfault. It probably ought to detect non-OK responses and report them appropriately.

$ curl -s --include  "http://localhost:9080/ws-bi-stream?products=elephant"
