Python library to convert `cURL`_ command to `HTTPie`_.
It will convert
.. code-block:: sh
curl -d name=admin -d shoesize=12 -d color=green&food=wet http://quan.hoabinh.vn
to
.. code-block:: sh
http -f http://quan.hoabinh.vn name=admin shoesize=12 color=green food=wet
Motivation
----------
This library was born when I joined a project with a team of non-Linux, non-Python developers. Because the project didn't have proper documentation, the other team often shared API usage example to me in form of cURL command, generated from their daily-used Postman. Those cURL commands are usually ugly, like this:
.. code-block:: sh
curl --location --request POST 'http://app-staging.dev/api' \
--header 'Content-Type: application/json' \
--data-raw '{
"userId": "abc-xyz",
"planAmount": 50000,
"isPromotion": false,
"createdAt": "2019-12-13 10:00:00"
}'
I am more comfortable with HTTPie (shorter syntax, has highlighting and is a Python application), so I often converted it to HTTPie:
.. code-block:: sh
http -F app-staging.dev/api userId=abc-xyz planAmount:=50000 isPromotion:=false createdAt='2019-12-13 10:00:00'
Though Postman can generate HTTPie, it does result in even uglier command:
.. code-block:: sh
printf '{
"userId": "abc-xyz",
"planAmount": 50000,
"isPromotion": false,
"createdAt": "2019-12-13 10:00:00"
}'| http --follow --timeout 3600 POST app-staging.dev/api \
Content-Type:'application/json'
Initially, I had to do conversion manually and quickly got tired from it. I tried to find a conversion tool but failed. There is an online tool `curl2httpie.online`_, but it failed with above example. So I decide to write my own tool.
I don't bother to help fix the online tool above, because it is written in Go. The rich ecosystem of Python, with these built-in libraries, enable me to finish the job fast:
- |shlex|_: Help parse the command line in form of shell language, handle the string escaping, quoting for me.
- |argparse|_: Help parse cURL options and arguments. Note that, cURL arguments syntax follow GNU style, which is common in Linux (and Python) world but not popular in Go world (see `this tutorial <go_tutorial_>`_), so it feels more natural with Python.
Usage
-----
.. code-block:: python
>>> from curlipie import curl_to_httpie
>>> curl = """curl -XPUT elastic.dev/movies/_doc/1 -d '{"director": "Burton, Tim", "year": 1996, "title": "Mars Attacks!"}' -H 'Content-Type: application/json'"""
>>> curl_to_httpie(curl)
ConversionResult(httpie="http PUT elastic.dev/movies/_doc/1 director='Burton, Tim' year:=1996 title='Mars Attacks!'", errors=[])
>>> result = curl_to_httpie(curl)
>>> result.httpie
"http PUT elastic.dev/movies/_doc/1 director='Burton, Tim' year:=1996 title='Mars Attacks!'"
Online tool
-----------
CurliPie is not very usable if it stays in library form, so I made an online tool for you to use it quickly:
https://curlipie.vercel.app
The site also provide HTTP API for you to develop a client for it.
Development
-----------
This repo contains three components:
- Python library ``curlipie``. This is the one `published`_ to PyPI.
- An API server built with `FastAPI`_, playing role of backend for `curlipie.vercel.app`_.
- A minimal frontend app built with `AlpineJS`_ and `TailwindCSS`_.
- Python dependencies are managed with `Poetry`_.
To try running on localhost:
- Run backend with:
.. code-block:: sh
uvicorn api.main:app
- The front-end are just static files, served by backend also, so you can access it via http://localhost:8000/. But because TailwindCSS is configured to strip unused CSS classes, you may need to rerun this command, inside *frontend-dev* folder, to keep your classes:
.. code-block:: sh
yarn build-tailwind
Unit test:
.. code-block:: sh
pytest
