[![Hex.pm](https://img.shields.io/hexpm/v/restc.svg?maxAge=2592000)](https://hex.pm/packages/restc) restclient -- An erlang REST Client library
====================================

## DESCRIPTION

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.

## USAGE

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
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">>},
{<<"X-GitHub-Req"...>>,<<"8E05:5C9"...>>}],
[{<<"current_user_url">>,<<"https://api.github.com/user">>},
{<<"current_user_authorizations_html_url">>,
<<"https://github.com/settings/connections/applications{/client_id}">>},
{<<"authorizations_url">>,
<<"https://api.github.com/authorizations">>},
{<<...>>,...},
{...}|...]}
3> restc:request(get, "https://api.github.com/herp-derp-404", [200]).
{error,404,
[{<<"Server">>,<<"GitHub.com">>},
{<<"Date">>,<<"Thu, 11 May 2017 07:37:27 GMT">>},
{<<"Content-Type">>,<<"application/json; charset=utf-8">>},
{<<"Content-Length">>,<<"77">>},
{<<"Status">>,<<"404 Not Found">>},
{<<"X-RateLimit-Limit">>,<<"60">>},
{<<"X-RateLimit-Remaining">>,<<"56">>},
{<<"X-RateLimit-Reset">>,<<"1494491776">>},
{<<"X-GitHub-Media-Type">>,<<"github.v3">>},
{<<"Access-Control-Expose-Headers">>,
<<"ETag, Link, X-GitHub-OTP, X-RateLimit-Limit, X-RateLimit"...>>},
{<<"Access-Control-Allow-Origin">>,<<"*">>},
{<<"Content-Security-Policy">>,<<"default-src 'none'">>},
{<<"Strict-Transport-Security">>,
<<"max-age=31536000; includeSubdomains; preload">>},
{<<"X-Content-Type-Options">>,<<"nosniff">>},
{<<"X-Frame-Options">>,<<"deny">>},
{<<"X-XSS-Protection">>,<<"1; mode=block">>},
{<<"X-GitHub-Request-Id">>,
<<"8C1D:5C90:54F34B8:6C6FF4D:59"...>>}],
[{<<"message">>,<<"Not Found">>},
{<<"documentation_url">>,
<<"https://developer.github.com/v3">>}]}

```

There's also convenience functions for working with urls and query string:

``` erlang
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"
```
