Android 指定为非null的参数是null异常，使用gson on web api返回null

如何防止gson从web api接收空对象

当Web api返回null时

{“事件”：null}

这将成为一个例外

java.lang.IllegalArgumentException: Parameter specified as non-null is null: method kotlin.jvm.internal.Intrinsics.checkParameterIsNotNull, parameter data

Gson使用

val data = gson.fromJson(apiRepository
                .doRequest(TheSportDBApi.getLatestMatch(league)),
                MatchResponse::class.java)

我的数据类

data class MatchResponse (val events: List<Match>)

---

)

MatchResponse类的事件变量可为空吗？比如：

val event: Event?

---

您可以在

kotlin

data class Article(
     val title: String, 
     val body: String, 
     val events: Events? = null, //Make it nullable
     val payWall: Boolean = false, 
     val titleImage: String? = null
)

data class Article(
     val title: String, 
     val body: String, 
     val events: Events? = null, //Make it nullable
     val payWall: Boolean = false, 
     val titleImage: String? = null
)
