Raku Land - Curlie

NAME

Curlie -- A simple HTTP client built on top of libcurl

DESCRIPTION

An HTTP Client built on libcurl, that provides an OO interface, logging and error handling.

SYNOPSIS

Create a new object manually:

use Curlie;
my \c = Curlie.new;

Any options sent in the constructor will be sent to libcurl's setopt.

my $username = 'alice';
my $password = 's3cret';
my \c = Curlie.new(:$username, :$password);

or create a new object automatically:

use Curlie :c;

Send a request, and print the full response headers and body:

say c.get('https://httpbin.org/get').res;
say c.get('https://httpbin.org/get?name=bob').res;
say c.get('https://httpbin.org/get', query => %( name => 'bob' )).res;
say c.get('https://httpbin.org/get', query => rocket => '🚀').res;

c.get: 'https://httpbin.org/get';
say c.res;
say c.res.content;

The response object is a Curlie::Response, and has the following methods: status, statusline, success, content, raw-headers, headers, and json.

Non-success responses return soft failures:

say c.get('https://httpbin.org/status/500').res;
# Fails with:
# HTTP/2 500
# and a stack trace

Which means to see the entire response, use it in a boolean context:

c.get('https://httpbin.org/status/500') or say c.res;
# Does not fail, prints:
# HTTP/2 500
# [ headers, response...]

If you also want to see the request, start a logger using Log::Async, and call c.debug beforehand:

use Log::Async;
logger.send-to($*ERR);
c.debug;
c.get('https://httpbin.org/status/500');

Add curl or ssl options to see extra libcurl or ssl messages:

c.debug(:curl, :ssl);

Getting json, posting json, posting forms work like this:

c.get: 'https://httpbin.org/status/200', :json;
c.post: 'https://httpbin.org/post', :json(:hello<world>);
c.post: 'https://httpbin.org/post', :form(:hello<world>);

The response object also has a json method which will decode the body:

say c.get('https://httpbin.org/get').res.json<url>
# https://httpbin.org/get

Also other headers can be sent in a headers argument

say c.get('https://httpbin.org/get', :headers(:X-Hello<world>)).res.json<headers><X-Hello>
# world

That's it! (so far!)
