Kotlin'da JSON bilan qanday ishlash mumkin?

Kotlinda JSON bilan ishlash odatda uchinchi tomon kutubxonalari yordamida amalga oshiriladi. Eng mashhurlari:

1. Jackson: Kuchli va moslashuvchan.
2. Gson: Google tomonidan, foydalanish oson.
3. kotlinx.serialization: Kotlinning tabiiy serializatsiya/deserializatsiyasi.

kotlinx.serialization dan foydalanish misoli:

1. build.gradle.kts faylida bog'liqliklarni qo'shing:

   // build.gradle.kts
   plugins {
       kotlin("jvm") version "1.9.22"
       kotlin("plugin.serialization") version "1.9.22"
   }
   
   repositories {
       mavenCentral()
   }
   
   dependencies {
       implementation("org.jetbrains.kotlinx:kotlinx-serialization-json:1.6.0")
   }
   

2. JSON tuzilmasini modellash uchun data class yarating:

   // JSON deserializatsiyasi uchun data class
   import kotlinx.serialization.Serializable
   
   @Serializable // Serializatsiya/deserializatsiya uchun annotatsiya
   data class User(
       val name: String,
       val age: Int
   )
   

3. JSON satrini ob'ektga deserializatsiya qilish:

   // JSON satrini deserializatsiya qilish
   import kotlinx.serialization.json.Json
   
   val jsonString = """{"name":"Alice","age":30}"""
   val user = Json.decodeFromString<User>(jsonString)
   
   // user.name "Alice" bo'ladi, user.age 30 bo'ladi
   

4. Ob'ektni JSON satriga serializatsiya qilish:

   // Ob'ektni JSON satriga serializatsiya qilish
   import kotlinx.serialization.json.Json
   
   val userToSerialize = User("Bob", 25)
   val jsonOutput = Json.encodeToString(userToSerialize)
   
   // jsonOutput {"name":"Bob","age":25} bo'ladi
   

Kutubxona tanlovi loyiha talablariga, ishlash tezligiga va qulayligiga bog'liq. kotlinx.serialization KMP loyihalari uchun afzal tanlov, chunki u tabiiy.
