Ktor 客户端 XML：将对象属性序列化为 XML 个子项

Question

是否可以设置 Ktor 客户端将对象属性序列化为 XML 个子项？

<PersonDTOXML>
  <id>1</id>
  <name>John</name>
  <age>20</age>
</PersonDTOXML>

默认情况下，对象属性被序列化为 XML 个属性。

<PersonDTOXML id="1" name="John" age="20" />

我正在学习 https://ktor.io/docs/serialization-client.html#receive_send_data

@Serializable
data class PersonDTOXML(val id: Int, val name: String, val age: Int)

Answer 1

您可以使用 XmlElement 注释来注释 PersonDTOXML class 的属性，以强制将它们序列化为 XML 元素：

@kotlinx.serialization.Serializable
data class PersonDTOXML(@XmlElement(true) val id: Int, @XmlElement(true) val name: String, @XmlElement(true) val age: Int)

另外，你可以写一个custom policy来重新定义Kotlin结构如何翻译成XML。
