Question

我需要在应用程序中发表评论。这已实施并且运行良好。现在，我有一个附加要求，即要上传照片和评论。因此，我在应用程序中实现了摄像头功能，现在将图像URI发送到GraphQL API。我已经在elixir中重构了架构和类型。但是，达到服务等级后，这些参数以某种方式消失了。

comment.ex

defmodule MyApp.Comment do
  use MyApp.Schema

  schema "comments" do
    field :art_id    , :string
    field :body      , :string
    field :image_url   , :string
    field :image_name  , :string

    belongs_to :user , User
    timestamps()
  end

  @optional_attributes ~w(body art_id image_url image_name)a

  def changeset(%Comment{} = schema, params) do
    schema
    |> cast(params, @optional_attributes)
    |> validate_required(@required_attributes)
  end
end

schema.ex包含：

 field :create_comment, :comment do
      arg :art_id, non_null(:string)
      arg :base64_image, :string
      arg :image_name, :string
      arg :body, :string

      middleware RequireAuth
      resolve &CommentService.create_comment/2
      middleware HandleErrors
 end

types.ex

object :comment do
    field :id     , :id
    field :art_id , :string
    field :body   , :string
    field :image_name  , :string
    field :image_url   , :image_url
    field :user   , :user do
      resolve &UserResolver.resolve/2
    end
  end

scalar :image_url, description: "S3 image url" do
    serialize fn(arg) ->
      {:ok, url} = MyApp.FileService.get_object_url(Application.get_env(:ex_aws, :bucket), arg)
      url
    end
  end

    artId
    body
  }
}

我不确定这是怎么回事。但是，这种变异只显示了古老的观点。它不包含添加的新参数。另外，在我的解析器服务中，我仅获得art_id和body作为参数，如下所示。

%{art_id: "comma-2005-06", body: "Sample picture"}

我想念什么吗？谁能帮忙吗？

不是药剂错误

这是由于FE中的架构定义不包含新属性。

架构定义语言

为了易于理解服务器的功能，GraphQL实现了一种人类可读的模式语法，称为其模式定义语言或“ SDL”。 SDL用于表示模式中可用的类型以及这些类型如何相互关联。

通过如下更新schema.graphql中的模式：

mutation createComment($artId: String!, $body: String, $base64Image: String, $imageName: String) {
  createComment(artId: $artId, body: $body, base64Image: $base64Image, imageName: $imageName) {
    ...commentData
  }
}

fragment commentData on Comment {
  id
  user {
    id
    fullName
  }
  artId
  body
  imageUrl
  imageName
}

GraphQL API现在可以正常工作。
