android - 如何在 Retrofit 中获取正确的数据

问题描述

我有 JSON 模型，

              "topPercent": 13.47
            }
          },
          {
            "name": "Special event kills",
            "value": 1377,
            "key": "specialEvent_kills",

            },
            "rankPlatformSpecific": {
              "rankPos": "NOT_CALCULATED_YET",
              "topPercent": "NOT_CALCULATED_YET"
            }
          },
          {
            "name": "Special event damage",
            "value": 656195,
            "key": "specialEvent_damage",
            "rank": {
              "rankPos": "NOT_CALCULATED_YET",
              "topPercent": "NOT_CALCULATED_YET"
            },
            "rankPlatformSpecific": {
              "rankPos": "NOT_CALCULATED_YET",
              "topPercent": "NOT_CALCULATED_YET"
            }
          },
          {
            "name": "Special event wins",
            "value": 68,
            "key": "specialEvent_wins",
            "rank": {
              "rankPos": "NOT_CALCULATED_YET",
              "topPercent": "NOT_CALCULATED_YET"
            },
            "rankPlatformSpecific": {
              "rankPos": "NOT_CALCULATED_YET",
              "topPercent": "NOT_CALCULATED_YET"
            }
          }
        ],
        "ImgAssets": {
          "icon": "https:\/\/api.mozambiquehe.re\/assets\/icons\/wraith.png",
          "banner": "https:\/\/api.mozambiquehe.re\/assets\/banners\/wraith.jpg"
        }
      }
    }
  }
}

然后我做一个数据类：

data class TestHero (@SerializedName("global") val global: PlayerInf,
                     @SerializedName("legends")val legends: AllLegends)

data class  PlayerInf (val name: String, val uid: Long, val avatar: String, val platform: String,
val  level: Int, val toNextLevelPercent: Int, val internalUpdateCount: Int, val bans: BanInf, val rank: RankInf)

data class BanInf (val isActive: Boolean, val remainingSeconds: Int)

data class RankInf (val rankScore: Int, val rankName: String, val rankDiv: Int, val rankImg: String)


data class AllLegends (@SerializedName("all") val all : Revenant, @SerializedName("all")val all2: Horizon)

data class Revenant (val ImgAssets: String)
data class Horizon (val data : ArrayList<Rang0>, val ImgAssets: String)

class Legends(){
    data class Revenant (val ImgAssets: String)
    data class Horizon (val data : ArrayList<Rang0>, val ImgAssets: String)
}

data class Rang (val t0 : Rang0)
data class Rang0 (val name: String, val value: Int, val key: String)

但我得到了错误：

无法为类创建转换器

在寻找 stackoverflow 的答案后，我意识到您不能对类对象进行双重序列化。但是你如何获得数据呢？我试图单独做，但结果只得到了 1 个对象示例的数据： data class AllLegends (@SerializedName("all") val all : Revenant) 请帮我弄清楚

解决方案

我认为这是已定义对象的地图，但每个图例都是未定义的

data class Legends(
    val all: Map<String, LegendWrapper> = emptyMap()
)

data class LegendWrapper(
    val data: Lis<PlayerPerformance>? = emptyList(),
    val ImgAssets: ImgAssets? = null

)

所以你可以定义一个类PlayerPerformance，ImgAssets但不能定义每个“图例”，因为每个“图例”的键都不是静态的，这就是映射的原因。

并且LegendWrapper您必须将dataand定义ImgAssets为可空值，因为某些“图例”没有它们。

这种方式在Legends你里面不需要Ravenant, Crypto, Horizon...等等。
