参数不匹配； SimpleXML [英] Parameter does not have a match; SimpleXML

问题描述

我正在将retrofit与SimpleXMLConverterFactory一起使用.

我总是得到

ConstructorException: Parameter 'success' does not have a match in class ResponseInfo

我不知道有什么问题. xml非常简单，我只需要success节点中的字符串.

And I have no idea what could be wrong. The xml is very simple and i only want the string from the success node.

xml:

<?xml version="1.0" encoding="UTF-8"?>
<response>
    <success>LoremIpsum</success>
</response>

ResponseInfo:

ResponseInfo:

@Root(strict = false, name = "response")
data class ResponseInfo(@Element(required = false, name = "success) var success: String)

我测试了Api调用，它返回了给定的xml.

Edit 1: I tested the Api call and it returns the given xml.

谢谢

推荐答案

所以最后，我设法解决了这个问题.

So finally, I managed myself to solve the problem.

问题是ResponseInfo类.在我将其更改为

The problem was the ResponseInfo class. After I changed it to

@Root(strict = false, name="response)
data class ResponseInfo @JvmOverloads constructor(
  @field:element(name = "success") var success: String = ""
)

一切正常.

您需要有一个空的构造函数，所有属性都必须是可变的(var)，并且必须在@Element -Annotation前面附加field:. @JvmOverloads与默认值结合将为您以及所有其他构造函数变体创建空构造函数.

You need to have an empty constructor, all properties must be mutable (var) and you have to append field: in front of the @Element-Annotation. @JvmOverloads combined with default values will create the empty constructor for you as well as all other constructor variations.
