phoenix-framework - 在Elixir/Phoenix中渲染 “OK”的最简单方法是什么？

Question

在Rails中，您可以直接渲染文本，例如render :text => 'OK'
Elixir / Phoenix中是否有快捷方式可以直接渲染文本，而无需定义模板或布局？

我发现的最短方法是:

  defmodule MyApp.PageController do
    use MyApp.Web, :controller

    def index(conn, _params) do
      # the file ok.html.eex contains just the string OK
      render conn, "ok.html", layout: false
    end
  end

有没有一种更短的方式来呈现“OK”，而不必提供模板文件“ok.html”？

从http://www.phoenixframework.org/docs/controllers:

Rendering

Controllers have several ways of rendering content. The simplest is to render some plain text using the text/2 function which Phoenix provides.

Let's say we have a show action which receives an id from the params map, and all we want to do is return some text with the id. For that, we could do the following.

def show(conn, %{"id" => id}) do
  text conn, "Showing id #{id}"
end
