如何解决延迟响应的JSON改型错误

Question

com.squareup.moshi.JsonDataException: Expected BEGIN_OBJECT but was BEGIN_ARRAY at path $*

我看了一下这个答案，但我不知道如何使它适应我的代码：reverfit应该是BEGIN_OBJECT，但应该是BEGIN_ARRAY

这是我的接口

interface LocationService {
    @GET("locations?countryid=fr")
    fun getLocationList() : Deferred<Response<LocationResponse>>
}

定位响应

data class LocationResponse (val results : List<Location>)

data class Location (
    @field:Json(name = "id") val id : String,
    @field:Json(name = "category") val category : String,
    @field:Json(name = "label") val label : String,
    @field:Json(name = "value") val value : String
)

[
  {
    "id":"city_39522",
    "category":"Villes",
    "label":"Parisot (81310)",
    "value":null
 },
 {
   "id":"city_36661",
   "category":"Villes",
   "label":"Paris 9ème (75009)",
   "value":null
 },
 {
   "id":"city_39743",
   "category":"Villes",
   "label":"Parisot (82160)",
   "value":null
 }
]

Answer 1

您必须将界面更新为：

interface LocationService {
    @GET("locations?countryid=fr")
    fun getLocationList() : Deferred<Response<List<Location>>>
}

此外，您不需要LocationResponse类并删除以下代码：

data class LocationResponse (val results : List<Location>)

您正在期待响应并像这样解析它：

{
  "results": [
    { .. }
  ]
}

 [
    { .. }
  ]
