# UriQuery

URI encode nested GET parameters and array values.

Prepares URI query parameters to be used in `URI.encode_query/1` or `HTTPoison.get/3`

## Installation

The package can be installed as:

  1. Add `uri_query` to your list of dependencies in `mix.exs`:

    ```elixir
    def deps do
      [{:uri_query, "~> 0.1.0"}]
    end
    ```

  2. Ensure `uri_query` is started before your application:

    ```elixir
    def application do
      [applications: [:uri_query]]
    end
    ```

## Usage

With list values

```elixir
iex> UriQuery.params(foo: ["bar", "quux"]) |> URI.encode_query
"foo%5B%5D=bar&foo%5B%5D=quux"

iex> HTTPoison.get("http://example.com", [], params: UriQuery.params(foo: ["bar", "quux"]))
```

WIth nested structures (maps or keyword lists)

```elixir
iex> UriQuery.params(%{user: %{name: "Dougal McGuire", email: "test@example.com"}}) |> URI.encode_query
"user%5Bemail%5D=test%40example.com&user%5Bname%5D=Dougal+McGuire"

iex> params = %{user: %{name: "Dougal McGuire", email: "test@example.com"}} |> UriQuery.params
[{"user[email]", "test@example.com"}, {"user[name]", "Dougal McGuire"}]
iex> HTTPoison.get("http://example.com", [], params: params)
```
