我在项目中使用retrofit
和moshi
库来帮助我连接到后端。从那里,我发回了日期,但显然moshi
无法处理日期。我已经编写了自己的JsonAdapter,但是现在出现错误:
com.squareup.moshi.JsonDataException:预期为BEGIN_OBJECT,但在路径$
上为BEGIN_ARRAY
class DateAdapter: JsonAdapter<Date>() {
@FromJson
override fun fromJson(reader: JsonReader): Date? {
val value = reader.nextString()
return SimpleDateFormat("yyyy-MM-dd", Locale.FRENCH).parse(value)
//return getDateInstance(DateFormat.LONG, Locale.FRENCH).parse(value)
}
@ToJson
override fun toJson(writer: JsonWriter, value: Date?) {
writer.value(SimpleDateFormat("yyyy-MM-dd", Locale.FRENCH).format(value))
}
}
private val moshi = Moshi.Builder()
.add(KotlinJsonAdapterFactory())
.add(DateAdapter())
.build()
private val retrofit = Retrofit.Builder()
.addConverterFactory(MoshiConverterFactory.create(moshi))
.addCallAdapterFactory(CoroutineCallAdapterFactory())
.baseUrl(BASE_URL)
.build()
// the request that throws the error
@GET("getPartiesNearYou")
fun getPatiesNearYou(
@Query("distance") distance: Int,
@Query("lat") lat: Double,
@Query("long") long: Double,
@Query("userId") userId: String

我已经进行了一些研究,并且大多数人谈论的事实是,您得到了一个数组而不是单个对象,并且需要更改某些东西,但是我不知道要添加什么@Wrapped
答案 0 :(得分:0)
您的json以数组开头,因此您必须在接口(在Java中为This ans)的数组中设置改型响应:-Call<List<ItemList>> getHomeContent();
