httpie-websockets is an HTTPie CLI plugin that adds WebSocket support to the HTTPie command line.

Features

• WebSocket Support: Seamlessly connect to WebSocket servers using the familiar HTTPie command line interface.
• Bidirectional Communication: Send and receive messages in real-time.
• Secure Connections: Supports both ws:// and wss:// protocols.
• Easy Integration: Simple installation and usage within the HTTPie environment.

Install

You can install by httpie plugins command:

httpie plugins install httpie-websockets

When you upgrade httpie-websockets by httpie plugins upgrade httpie-websockets, the dist dir of lower version will not be removed. You can remove it manually if you want. On Mac it's in ~/.config/httpie/plugins/lib/python3.12/site-packages.

or use pip in the same environment with httpie

pip install httpie-websockets

If your httpie is installed with pipx, you also can use pipx to install httpie-websockets.

Suppose your httpie environment is named httpie.

# Replace httpie with your httpie venv name
pipx runpip httpie install -U httpie-websockets

Usage

After install this plugin, just pass websocket url to http command.

http ws://localhost:8000/ws

This allows HTTPie to interact with WebSocket servers directly from the command line.

Example:

$ http wss://echo.websocket.org
Request served by 7811941c69e658  <== This msg is from server
> Connected to wss://echo.websocket.org
> Type a message and press enter to send it.
> The backslash at the end of a line is treated as input not ended.
> Press Ctrl+C to close the connection.

When you press CTRL+C, connection will disconnect and httpie will get handshake response headers and websocket connection info with close code and close message like below:

^C
Oops! Disconnecting. Need to force quit? Press again!
HTTP/1.1 200

Debug Log

You can set HTTPIE_WS_LOG_LEVEL to DEBUG to see httpie_websocket debug log for more information.

On linux and Mac:

export HTTPIE_WS_LOG_LEVEL=DEBUG

Or

HTTPIE_WS_LOG_LEVEL=DEBUG http wss://echo.websocket.org

On Windows:

set HTTPIE_WS_LOG_LEVEL=DEBUG

Or

# Powershell
$env:HTTPIE_WS_LOG_LEVEL="DEBUG"; http wss://echo.websocket.org
# Cmd
cmd /C "set HTTPIE_WS_LOG_LEVEL=DEBUG &&; http wss://echo.websocket.org"

Proxy & Cert

This project using websocket-client to establish connection, support proxy and custom cert file. You can pass proxy and cert to httpie.

Support http, socks4, socks4a, socks5 and socks5h proxy protocol.

http wss://echo.websocket.org --proxy=http://proxy.com
http wss://echo.websocket.org --proxy=socks4://proxy.com
http wss://echo.websocket.org --proxy=socks4a://proxy.com
http wss://echo.websocket.org --proxy=socks5://proxy.com
http wss://echo.websocket.org --proxy=socks5h://proxy.com

Custom cert file same as httpie.

http wss://yourservice.com --cert=/path/to/cert --cert-key=/path/to/cert-key --cert-key-pass=pass

Headers

Also support custom headers, you can send header through httpie.

Note wss://echo.websocket.org does not support any authentication, and will ignore any headers you send.

http wss://echo.websocket.org Custom-Header:Custom-value

Subprotocol

You can send subprotocols from the headers. Multiple subprotocols need to be separated by commas, since httpie receives only the first one with the same headers key.

http wss://echo.websocket.org Sec-WebSocket-Protocol:sub1,sub2

Auth

Support pass auth option and auth-type.

basic: httpie use basic auth as default.

http wss://echo.websocket.org --auth=user1:pass

Websocket server will receive a header like 'Authorization': 'Basic dXNlcjE6dGVzdA=='.

bearer: similar with basic.

http wss://echo.websocket.org --auth-type=bearer --auth=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c

Websocket server will receive a header like 'Authorization': 'Bearer eyxxxx'

digest: Technically, digest authentication is not supported, but you can generate an auth header manually if you want.

http wss://echo.websocket.org "Authorization: Digest username='user', realm='example', nonce='c3a7f38c-5e5a-45b2-a5b5-3b5e2c5c5c5c', uri='/path/to/protected/resource', response='generated_response', qop=auth, nc=00000001, cnonce='generated_cnonce', opaque='6d6b8f8f-6b8f-6b8f-6b8f-6b8f6b8f6b8f'"

Session

Support session option and perform as a header.

http wss://echo.websocket.org -s user1

Similar like basic auth, server will receive a header like 'Authorization': 'Basic dXNlcjE6dGVzdA=='.

Verify

You can disable SSL verification by using the --verify=no option

http wss://echo.websocket.org --verify=no

Timeout

Pass time out option to waiting for connection establish.

http wss://echo.websocket.org --timeout=3

Messages Download

Message download functionality is no longer supported because the plugin cannot access the httpie environment, making it impossible to manage both stdout and messages simultaneously.

Multi-line Input Support

The backslash at the end of a line is treated as input not ended, only the end-of-line.

If you want to input a multiline input, use \ at the end of the line just like bash.

Example:

One backslash at the end of a line

hello\
 world!

Will send as hello world!

Multiple backslashes at the end of a line

hello\\\
  world!

Will send as hello\ world!, assume you input two whitespace ahead of world!.

Not at the end-of-line

hel\\lo\
 world!

Will send as hel\\lo world!
