HTTP Prompt is an interactive command-line HTTP client featuring autocomplete and syntax highlighting, built on HTTPie and prompt_toolkit.

Just install it like a regular Python package:

$ pip install http-prompt

You'll probably see some permission errors if you're trying to install it on the system-wide Python. It isn't recommended. But if that's what you want to do, you need to sudo:

$ sudo pip install http-prompt

Another alternative is to use --user option to install the package into your user directory:

$ pip install --user http-prompt

To upgrade HTTP Prompt, do:

$ pip install -U http-prompt

To start a session, you use the http-prompt executable:

# Start with the given URL
$ http-prompt http://httpbin.org

# Or start with some initial options
$ http-prompt localhost:8000/api --auth user:pass username=somebody

Once you're in a session, you can use the following commands.

To change URL address, use cd:

# Relative URL path
> cd api/v1

# Absolute URL
> cd http://localhost/api

To add headers, querystring, or body parameters, use the syntax as in HTTPie. The following are all valid:

> Content-Type:application/json username=john
> 'name=John Doe' apikey==abc
> Authorization:"Bearer auth_token"

You can also add HTTPie options like this:

> --form --auth user:pass
> --verify=no username=jane

To preview how HTTP Prompt is going to call HTTPie, do:

> httpie post
http --auth user:pass --form POST http://localhost/api apikey==abc username=john

You can temporarily override the request parameters by supplying options and parameters in httpie command. The overrides won't affact the later requests.

# No parameters initially
> httpie
http http://localhost

# Override parameters temporarily
> httpie /api/something page==2 --json
http --json http://localhost/api/something page==2

# Current state is not affected by the above overrides
> httpie
http http://localhost

To actually send a request, enter one of the HTTP methods:

> get
> post
> put
> patch
> delete
> head

The above HTTP methods also support temporary overriding:

# No parameters initially
> httpie
http http://localhost

# Send a request with some overrided parameters
> post /api/v1 --form name=jane

# Current state remains intact
> httpie
http http://localhost

To remove an existing header, a querystring parameter, a body parameter, or an HTTPie option:

> rm -h Content-Type
> rm -q apikey
> rm -b username
> rm -o --auth

To reset the session, i.e., clear all parameters and options:

> rm *

To exit a session, simply enter:

> exit

Note that all the options are gone once you exit.
