以下作品:
package com.squareup.moshi.problem
import com.squareup.moshi.JsonClass
import com.squareup.moshi.Moshi
@JsonClass(generateAdapter = true)
data class Foo(
val bar: String?
)
fun main() {
val adapter=Moshi.Builder().build().adapter<Foo>(Foo::class.java)
adapter.fromJson("{}")
}
但是使用列表时失败:
package com.squareup.moshi.problem
import com.squareup.moshi.JsonClass
import com.squareup.moshi.Moshi
@JsonClass(generateAdapter = true)
data class Foo(
val bar: List<String>?
)
fun main() {
val adapter=Moshi.Builder().build().adapter<Foo>(Foo::class.java)
adapter.fromJson("{}")
}
与:
Exception in thread "main" com.squareup.moshi.JsonDataException: Required value 'bar' missing at $

如何使其适用于列表?
这是显示问题的存储库:https://github.com/ligi/moshi_problem
最佳答案
问题实际上是moshi中的此错误:

帽子提示@cketti,向我指出了这个问题。
关于kotlin - moshi可为空的列表失败,出现 “required value”,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/58820520/
