restclient is a library to help with consuming RESTful web services. It supports encoding and decoding JSON, Percent and XML and comes with a convenience function for working with urls and query parameters.
Include restclient as a rebar dependency with:
{deps, [{restc, ".*", {git, "git://github.com/kivra/restclient.git", {tag, "0.8.2"}}}]}.
You have to start inets before using the client and if you want to use https make sure to start ssl before. Then you can use the client as:
Erlang/OTP 19 [erts-8.2] [source] [64-bit] [smp:8:8] [async-threads:0] [kernel-poll:false]
Eshell V8.2 (abort with ^G)
1> application:ensure_all_started(restc).
{ok,[idna,mimerl,certifi,ssl_verify_fun,metrics,hackney,
mochiweb_util,restc]}
2> restc:request(get, "https://api.github.com").
{ok,200,
[{<<"Server">>,<<"GitHub.com">>},
{<<"Date">>,<<"Thu, 11 May 2017 07:36:16 GMT">>},
{<<"Content-Type">>,<<"application/json; charset=utf-8">>},
{<<"Content-Length">>,<<"2039">>},
{<<"Status">>,<<"200 OK">>},

3> restc:request(get, "https://api.github.com/herp-derp-404", [200]).
{error,404,

[{<<"message">>,<<"Not Found">>},
{<<"documentation_url">>,
<<"https://developer.github.com/v3">>}]}
There's also convenience functions for working with urls and query string:
7> restc:construct_url("http://www.example.com/te", "res/res1/res2", [{"q1", "qval1"}, {"q2", "qval2"}]).
"http://www.example.com/te/res/res1/res2?q1=qval1&q2=qval2"The KIVRA restclient library uses an MIT license. So go ahead and do what you want!
Lots of fun!
