Question

安装absinthe_plug后，我收到以下错误：

= Compilation error in file lib/kerrigan_api_web/router.ex ==
** (UndefinedFunctionError) function KerriganApiWeb.Absinthe.Plug.init/1 is undefined (module KerriganApiWeb.Absinthe.Plug is not available)

这是我的代表

{:phoenix, "~> 1.3.0"},
  {:phoenix_pubsub, "~> 1.0"},
  {:phoenix_ecto, "~> 3.2"},
  {:postgrex, ">= 0.0.0"},
  {:phoenix_html, "~> 2.10"},
  {:phoenix_live_reload, "~> 1.0", only: :dev},
  {:gettext, "~> 0.11"},
  {:cowboy, "~> 1.0"},
  {:poison, "~> 3.1"},
  {:absinthe, "~> 1.3.0"},
  {:absinthe_plug, "~> 1.3.0"},
  {:absinthe_ecto, git: "https://github.com/absinthe-graphql/absinthe_ecto.git"},
  {:faker, "~> 0.7"},

据我所知，我不需要添加任何其他内容。我已按照这里的简单步骤进行操作：

absinthe_slug

编辑：我的路由器

defmodule KerriganApiWeb.Router do
  use KerriganApiWeb, :router

  pipeline :browser do
    plug :accepts, ["html"]
    plug :fetch_session
    plug :fetch_flash
    plug :protect_from_forgery
    plug :put_secure_browser_headers
  end

  pipeline :api do
    plug :accepts, ["json"]
  end

  scope "/", KerriganApiWeb do
    pipe_through :browser # Use the default browser stack

    get "/", PageController, :index
    resources "/hotsdata_user", UserController, except: [:new, :edit]
    resources "/battletag_toonhandle_lookup", PlayerController, except: [:new, :edit]

    forward "/graph", Absinthe.Plug, schema: KerriganApi.Schema
    forward "/graphiql", Absinthe.Plug.GraphiQL, schema: KerriganApi.Schema
  end

end

我添加了要求Absinthe.Plug，但那不起作用

Answer 1

您将alias（KerriganApiWeb）传递给scope，Absinthe.Plug将所有模块的别名预先传递给内部的路由声明函数。这会在KerriganApiWeb.Absinthe.Plug的调用中将forward转换为Absinthe.Plug，这不是您想要的。您需要模块alias。有两种方法可以解决这个问题：

删除KerriganApiWeb参数并在所有需要它的路由声明函数中显式使用scope "/" do pipe_through :browser # Use the default browser stack get "/", KerriganApiWeb.PageController, :index resources "/hotsdata_user", KerriganApiWeb.UserController, except: [:new, :edit] resources "/battletag_toonhandle_lookup", KerriganApiWeb.PlayerController, except: [:new, :edit] forward "/graph", Absinthe.Plug, schema: KerriganApi.Schema forward "/graphiql", Absinthe.Plug.GraphiQL, schema: KerriganApi.Schema end。
```
scope
```

使用相同的路径和管道创建新的forward并在那里声明scope "/", KerriganApiWeb do pipe_through :browser # Use the default browser stack get "/", PageController, :index resources "/hotsdata_user", UserController, except: [:new, :edit] resources "/battletag_toonhandle_lookup", PlayerController, except: [:new, :edit] end scope "/" do forward "/graph", Absinthe.Plug, schema: KerriganApi.Schema forward "/graphiql", Absinthe.Plug.GraphiQL, schema: KerriganApi.Schema end路由：

Phoenix文档say第一个会增加应用程序的编译时间。即使不是这种情况，我也会选择第二个，因为我发现它更具可读性。

您可以将两个端点“/ graph”和“graphiql”移出范围“/".
