如何在没有Phoenix的情况下配置Plug.Static

问题描述

我试图弄清楚如何在没有任何其他框架(Phoenix，Sugar等)的情况下 Static 配置；只是牛仔，即插即用药.我只是不知道如何将这些东西放到路由器中.

I am trying to figure out how to configure Plug.Static without any other framework (Phoenix, Sugar, etc); just Cowboy, Plug and Elixir. I just don't know how to put things together in the Router.

  plug :match
  plug Plug.Static, at: "/pub", from: :cerber
  plug :dispatch

  get "/" do
    Logger.info "GET /"
    send_resp(conn, 200, "Hello world\n")
  end

1. Plug.Static的声明是否在正确的位置?不应该在plug :dispatch之后吗?
2. 我是否需要定义其他路线
3. 使用以下声明:

1. Is the declaration of Plug.Static at the right place ? Shouldn't it be after plug :dispatch ?
2. Do I need to define an additional route
3. With this declaration:

1. 要访问的URL是什么，例如index.html?
2. 文件系统index.html上应位于的位置

1. what is the URL to reach, say index.html?
2. where on the file system index.html should be located

我只是失去了.

I'm just lost.

推荐答案

看看 Plug.Router文档了解:match和:dispatch的工作方式. :match将尝试查找匹配的路由，而:dispatch将调用它.这意味着仅当路由器中有匹配的路由时，才会调用设置中的Plug.Static，这没有任何意义.您想在所有内容之前先plug Plug.Static.请记住，插件只是按声明顺序调用的函数.

Take a look at Plug.Router docs for how :match and :dispatch works. :match will try to find a matching route and :dispatch is going to invoke it. This means Plug.Static in your setup will only be invoked if you have a matching route in your router, which doesn't make sense. You want plug Plug.Static before everything. Remember plugs are just functions that are invoked in the order they are declared.

除此之外，您的Plug.Static设置似乎还可以.您当前的配置将在"/pub"提供资产，这意味着"/pub/index.html"将在您的应用中查找"priv/static/index.html".此处的更多信息: http://hexdocs.pm/plug/Plug.Static.html

Other than that, your Plug.Static setup seems ok. Your current configuration will serve assets at "/pub", meaning "/pub/index.html" will look for "priv/static/index.html" in your app. More info here: http://hexdocs.pm/plug/Plug.Static.html
