## Usage
### Phoenix Integration

Inside `web/router.ex` file, add plug to your pipeline like so:

```elixir
defmodule MyApp.Router
use Phoenix.Router

pipeline :api do
plug SimpleTokenAuthentication
end

scope "/", MyApp do
pipe_through :api
get "/hello", HelloController, :hello
end
end
```
## Installation

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

```elixir
def deps do
[{:simple_token_authentication, "~> 0.6.0"}]
end
```

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

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

3. Configure your token in `config.exs`:
```elixir
config :simple_token_authentication,
token: "your-token-here",
service_tokens: [
service_a: "service-a-token",
service_b: "service-b-token"
]
```

4. Configure your connecting application to pass a token in the `authorization` header, e.g.:
```elixir
put_header("authorization", "your-token-here")
```

## Realm

Optionally, you can add a realm to the simple auth. This allows services to use the plug multiple times with different realms
For example:

Configure your token under a named realm in `config.exs`:
```elixir
config :simple_token_authentication,
another_realm: [
service_tokens: [
service_a: "service-a-token",
service_b: "service-b-token"
]
]
```

Pass that name when configuring the plug:
```elixir
defmodule MyApp.Router
use Phoenix.Router

pipeline :api do
plug SimpleTokenAuthentication, auth_realm: :another_realm
end

scope "/", MyApp do
pipe_through :api
get "/hello", HelloController, :hello
end
end
```

## Notes

- Token value can be a comma-separated list of tokens
- Specifying `service_tokens` is optional
- Auth will succeed if token exists in *either* list (`token` or `service_tokens`)
- Use of a service token will add "service_name" to `Logging.metadata`
- Service can be identified in the conn.assigns[:simple_token_auth_service]. Will be the name of the service or :global when matching the token key
