Can'；t在Kotlin中解析json

我有这样一个json：

{"ok":true,"result":[{"update_id":853803195,
"message":{"message_id":313,"from":{"id":104906563,"is_bot":false,"first_name":"AL","username":"alzvaracc","language_code":"en"},"chat":{"id":104906563,"first_name":"AL","username":"alzvaracc","type":"private"},"date":1594723984,"text":"/start","entities":[{"offset":0,"length":6,"type":"bot_command"}]}},{"update_id":853803196,
"message":{"message_id":314,"from":{"id":104906563,"is_bot":false,"first_name":"AL","username":"alzvaracc","language_code":"en"},"chat":{"id":104906563,"first_name":"AL","username":"alzvaracc","type":"private"},"date":1594723986,"text":"e"}},{"update_id":853803197,
"message":{"message_id":325,"from":{"id":104906563,"is_bot":false,"first_name":"AL","username":"alzvaracc","language_code":"en"},"chat":{"id":104906563,"first_name":"AL","username":"alzvaracc","type":"private"},"date":1594734252,"text":"\ud83d\ude06"}},{"update_id":853803198,
"message":{"message_id":328,"from":{"id":104906563,"is_bot":false,"first_name":"AL","username":"alzvaracc","language_code":"en"},"chat":{"id":104906563,"first_name":"AL","username":"alzvaracc","type":"private"},"date":1594736358,"text":"5"}}]}

Unable to instantiate Response with parameters [ok: true, result: [, , , ]]

[java.lang.Object@680362a, java.lang.Object@3569edd5, java.lang.Object@1f651cd8, java.lang.Object@7d0332e1]

我在用图书馆。 就像在第一个示例中，我创建了一个类：

class Response(val ok: Boolean, val result: String)

我试图将第二个参数保存到一个字符串中，以便稍后也可以解析它。但我有一个例外：

{"ok":true,"result":[{"update_id":853803195,
"message":{"message_id":313,"from":{"id":104906563,"is_bot":false,"first_name":"AL","username":"alzvaracc","language_code":"en"},"chat":{"id":104906563,"first_name":"AL","username":"alzvaracc","type":"private"},"date":1594723984,"text":"/start","entities":[{"offset":0,"length":6,"type":"bot_command"}]}},{"update_id":853803196,
"message":{"message_id":314,"from":{"id":104906563,"is_bot":false,"first_name":"AL","username":"alzvaracc","language_code":"en"},"chat":{"id":104906563,"first_name":"AL","username":"alzvaracc","type":"private"},"date":1594723986,"text":"e"}},{"update_id":853803197,
"message":{"message_id":325,"from":{"id":104906563,"is_bot":false,"first_name":"AL","username":"alzvaracc","language_code":"en"},"chat":{"id":104906563,"first_name":"AL","username":"alzvaracc","type":"private"},"date":1594734252,"text":"\ud83d\ude06"}},{"update_id":853803198,
"message":{"message_id":328,"from":{"id":104906563,"is_bot":false,"first_name":"AL","username":"alzvaracc","language_code":"en"},"chat":{"id":104906563,"first_name":"AL","username":"alzvaracc","type":"private"},"date":1594736358,"text":"5"}}]}

Unable to instantiate Response with parameters [ok: true, result: [, , , ]]

[java.lang.Object@680362a, java.lang.Object@3569edd5, java.lang.Object@1f651cd8, java.lang.Object@7d0332e1]

我尝试将结果设置为

JsonObject

（或者

JsonObjects

的

JsonArray

），得到了这个结果

Unable to instantiate JsonObject with parameters []

唯一或多或少起作用的是一份清单。结果变成如下所示的java对象列表：

{"ok":true,"result":[{"update_id":853803195,
"message":{"message_id":313,"from":{"id":104906563,"is_bot":false,"first_name":"AL","username":"alzvaracc","language_code":"en"},"chat":{"id":104906563,"first_name":"AL","username":"alzvaracc","type":"private"},"date":1594723984,"text":"/start","entities":[{"offset":0,"length":6,"type":"bot_command"}]}},{"update_id":853803196,
"message":{"message_id":314,"from":{"id":104906563,"is_bot":false,"first_name":"AL","username":"alzvaracc","language_code":"en"},"chat":{"id":104906563,"first_name":"AL","username":"alzvaracc","type":"private"},"date":1594723986,"text":"e"}},{"update_id":853803197,
"message":{"message_id":325,"from":{"id":104906563,"is_bot":false,"first_name":"AL","username":"alzvaracc","language_code":"en"},"chat":{"id":104906563,"first_name":"AL","username":"alzvaracc","type":"private"},"date":1594734252,"text":"\ud83d\ude06"}},{"update_id":853803198,
"message":{"message_id":328,"from":{"id":104906563,"is_bot":false,"first_name":"AL","username":"alzvaracc","language_code":"en"},"chat":{"id":104906563,"first_name":"AL","username":"alzvaracc","type":"private"},"date":1594736358,"text":"5"}}]}

但我不知道该怎么对付他们<所以我的问题是我该怎么做？我怎样才能得到我能处理的结果呢？

试试这门课

import com.beust.klaxon.*

private val klaxon = Klaxon()

data class User (
    val ok: Boolean,
    val result: List<Result>
) {
    public fun toJson() = klaxon.toJsonString(this)

    companion object {
        public fun fromJson(json: String) = klaxon.parse<User>(json)
    }
}

data class Result (
    @Json(name = "update_id")
    val updateID: Long,

    val message: Message
)

data class Message (
    @Json(name = "message_id")
    val messageID: Long,

    val from: From,
    val chat: Chat,
    val date: Long,
    val text: String,
    val entities: List<Entity>? = null
)

data class Chat (
    val id: Long,

    @Json(name = "first_name")
    val firstName: String,

    val username: String,
    val type: String
)

data class Entity (
    val offset: Long,
    val length: Long,
    val type: String
)

data class From (
    val id: Long,

    @Json(name = "is_bot")
    val isBot: Boolean,

    @Json(name = "first_name")
    val firstName: String,

    val username: String,

    @Json(name = "language_code")
    val languageCode: String
)

导入com.beust.klaxon* private val klaxon=klaxon（） 数据类用户( val ok:布尔值， val结果：列表 ) { public-fun-toJson（）=klaxon.toJsonString（this） 伴星{ public-fun-fromJson（json:String）=klaxon.parse（json） } } 数据类结果( @Json（name=“update\u id”） 瓦尔：很长， val消息：消息 ) 数据类消息( @Json（name=“message\u id”） val messageID:Long， val from：from， val聊天室：聊天室， val日期：长， val text:String， val实体：列表？=null ) 数据类聊天( val id:Long， @Json（name=“first_name”） val firstName:String， val用户名：String， val类型：String ) 数据类实体( val偏移量：长， val长度：长， val类型：String ) 来自的数据类( val id:Long， @Json（name=“is_bot”） val-isBot:Boolean， @Json（name=“first_name”） val firstName:String， val用户名：String， @Json（name=“language\u code”） val语言代码：String )

太好了，很有效，谢谢！现在我感到内疚，有人为我做了所有的解析。。。不过我想到了，我想下次我会设法的。非常感谢。@AlexanderDay您也可以从这里解析它
