A copycat for the great lib https://github.com/websockets/wscat but it does not need to install anything in advance like Node. Thus, it's suitable for environments where you cannot install software at will, such as your online servers.
To install with Homebrew, run:
brew install ylgrgyq/homebrew-tap/wsdog
Alternatively, you can download binary for your OS.
Usage:
wsdog [OPTIONS]
Application Options:
-l, --listen= listen on port
-c, --connect= connect to a WebSocket server
--debug enable debug log
--no-color Run without color
-P, --show-ping-pong print a notification when a ping or pong is received
-s, --subprotocol= optional subprotocol (default: )
Connect To A WebSocket Server Options:
-o, --origin= optional origin
-x, --execute= execute command after connecting
-w, --wait= wait given seconds after executing command (default: 2)
--host= optional host
-n, --no-check Do not check for unauthorized certificates
-H, --header= Set an HTTP header <header:value>. Repeat to set multiple like -H header1:value1 -H header2:value2.
--auth= Add basic HTTP authentication header <username:password>.
--slash Enable slash commands for control frames (/ping, /pong, /close [code [, reason]], /binary [Base64])
Help Options:
-h, --help Show this help message
$ wsdog -c ws://echo.websocket.org
Connected (press CTRL+C to quit)
> hi there
< hi there
> are you a happy parrot?
< are you a happy parrot?
For Binary Message, wsdog support write and print it in Base64 format. Such as
$ wsdog -c ws://echo.websocket.org --slash
Connected (press CTRL+C to quit)
> /binary SGVsbG8gd29ybGQh
<< SGVsbG8gd29ybGQh
Please note that the --slash option must be provided to active Slash Command Mode so we can use /binary command to send Binary Message in Base64. SGVsbG8gd29ybGQh is Hello world! in Base64. The leading << means wsdog receives a Binary Message and print it's payload in Base64 format on the console. For Text Message, the payload will be print after < mark.
