转换＆＃34; e;和＆＃39;在rails中适当的字符

Question

我正在处理涉及API的第一个项目。

我正在使用的API为我提供了以下字符串：

"In our nation’s capital, killings have risen by 50 percent."

有没有办法可以简单地将代码转换为字符？或者我是否需要一遍又一遍地呼叫gsub？

Answer 1

在Ruby On Rails中，你可以尝试下面的行显示HTML

type Msg
    = DragStart Position
    | DragAt Position
    | DragEnd Position


update : Msg -> Model -> ( Model, Cmd Msg )
update msg model =
  ( updateHelp msg model, Cmd.none )


updateHelp : Msg -> Model -> Model
updateHelp msg ({position, drag} as model) =
  case msg of
    DragStart xy ->
      Model position (Just (Drag xy xy))

    DragAt xy ->
      Model position (Maybe.map (\{start} -> Drag start xy) drag)

    DragEnd _ ->
      Model (getPosition model) Nothing



-- SUBSCRIPTIONS


subscriptions : Model -> Sub Msg
subscriptions model =
  case model.drag of
    Nothing ->
      Sub.none

    Just _ ->
      Sub.batch [ Mouse.moves DragAt, Mouse.ups DragEnd ]

它将输出如下：＆＃34;在我们国家的首都，杀人事件增加了50％。＆＃34;
