我有这个数据使用http://jsonapi.org/ http://jsonapi.org/ format:
{
"data": [
{
"type": "prospect",
"id": "1",
"attributes": {
"provider_user_id": "1",
"provider": "facebook",
"name": "Julia",
"invitation_id": 25
}
},
{
"type": "prospect",
"id": "2",
"attributes": {
"provider_user_id": "2",
"provider": "facebook",
"name": "Sam",
"invitation_id": 23
}
}
]
}
我的模型如下:
type alias Model = {
id: Int,
invitation: Int,
name: String,
provider: String,
provider_user_id: Int
}
type alias Collection = List Model
我想将 json 解码为 Collection,但不知道如何。
fetchAll: Effects Actions.Action
fetchAll =
Http.get decoder (Http.url prospectsUrl [])
|> Task.toResult
|> Task.map Actions.FetchSuccess
|> Effects.task
decoder: Json.Decode.Decoder Collection
decoder =
?
如何实现解码器?谢谢
