riak-erlang-http-client is an Erlang client for Riak, using the HTTP interface

Quick Start

You must have Erlang/OTP R15B01 or later and a GNU-style build system to compile and run riak-erlang-http-client.

git clone git://github.com/basho/riak-erlang-http-client.git
cd riak-erlang-http-client

If the Protocol Buffers Riak Erlang Client (riak-erlang-client) is already familiar to you, you should find this client familiar. Just substitute calls to riakc_pb_socket with calls to rhc.

As a quick example, here is how to create and retrieve a value with the key “foo” in the bucket “bar” using the riak-erlang-http-client.

First, start up an Erlang shell with the path to riak-erlang-http-client and all dependenciess included, then start sasl and ibrowse:

erl -pa path/to/riak-erlang-http-client/ebin path/to/riak-erlang-http-client/deps/*/ebin
Eshell V5.8.2  (abort with ^G)
1> [ ok = application:start(A) || A <- [sasl, ibrowse] ].

Next, create your client:

2> IP = "",
2> Port = 8098,
2> Prefix = "riak",
2> Options = [],
2> C = rhc:create(IP, Port, Prefix, Options).

Sidenote: if you will be using the defaults, as in the example above, you may call rhc:create/0 instead of specifying the defaults yourself.

Create a new object, and store it with rhc:put/2:

3> Bucket = <<"bar">>,
3> Key = <<"foo">>,
3> Data = <<"hello world">>,
3> ContentType = <<"text/plain">>,
3> Object0 = riakc_obj:new(Bucket, Key, Data, ContentType),
3> rhc:put(C, Object0).

Retrieve an object with rhc:get/3:

4> Bucket = <<"bar">>,
4> Key = <<"foo">>,
4> {ok, Object1} = rhc:get(C, Bucket, Key).
                 <<"hello world">>}],
