how to send POST request

jschwinger233 commented 4 years ago

I want to send request as followed:

POST /v1.40/exec/fd1cfa1baccabe2cc990db8a89b77c172d2625d2ac10f0d484499cd19c90e084/start HTTP/1.1
Host: localhost:2375
User-Agent: Docker-Client/19.03.2 (darwin)
Content-Length: 28
Connection: Upgrade
Content-Type: application/json
Upgrade: tcp

{"Detach":false,"Tty":true}

but I failed to find the arguments to specify request method as well as post body...

oh never mind, I figured it out using telnet...

$ telnet localhost 2375
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

but it can be really helpful if websocat can achieve this conveniently, thanks~

May happen with Websocat 2.0. Here is some bit of preview:

HTTP body cannot be specified yet, an option needs to be added for this.

Do you want an early pre-built pre-alpha version of Websocat with this feature? Option names may be changed before the release. If yes, specify platform.

thank you very much all the same!
