aclh

Async Command-line HTTP Client

Features

• Supports Asynchronous HTTP requests from command-line.

• Can handle 100 or even 1000+ HTTP requests asynchronously in a single thread (Thanks to aiohttp).

• Ability to resume partial downloads.

• Ability to accept input from files containing urls with custom parameters.

• Automatic HTML Formatting, in order to make reading of HTML content easier inside terminal (Thanks to bs4).

• Allows adjusting maximum number of concurrent requests.

• Allows adjusting time duration between successive requests to same domain.

• Supports two backends urllib and aiohttp for fetching urls.

• Built-in lightweight crawler

Why to use aclh?

If users want to fire just one request at a time from cli then there is no need to use aclh, since existing clients like curl or wget are sufficient for this. But, if users are interested in firing 100+ or more concurrent requests asynchronously without creating 100+ or more separate processes, then they might find aclh useful.

Note: use pip or pip3 depending on what is available on your system

Uninstall

Brief Documentation:

1. Fetch three urls and print their formatted HTML output in terminal

    $ aclh https://en.wikipedia.org https://mr.wikipedia.org https://www.duckduckgo.com
   

2. Fetch Two urls asynchronously and save their output in two separate files

    $ aclh https://en.wikipedia.org https://mr.wikipedia.org --out en.html mr.html
   

3. Fetch Two urls asynchronously and save their output in a directory with default names.

    $ aclh https://en.wikipedia.org https://mr.wikipedia.org --out=/tmp
   

4. Fetch Two urls asynchronously, do not print output on terminal but print cookies and links within pages.

    $ aclh https://en.wikipedia.org https://mr.wikipedia.org --no-print --print-cookies --print-links
   

5. Fetch urls with options from files

    $ aclh --input-files file1.txt file2.txt
   

6. Send common Custom header when fetching two urls

    $ aclh https://en.wikipedia.org https://www.python.org/ --hdrs 'User-Agent:Mozilla/5.0' 'Cookie: custom_cookie'
   

7. Crawl website asynchronously and keep time duration of 1s between successive requests

    $ aclh -X CRAWL 'https://docs.python.org/3/' --depth-allowed=1 --wait=1.0
   

8. help

    $ aclh -h
   

How does it achieve async?

Using Vinanti and aiohttp. All the heavy lifting is done by these two libraries. aclh provides cli wrapper around them.
