java.lang.NumberFormatException: android中的double："5b80393f7fca491488980fe1“无效

我有个Kotlin课程
class CategoryJsonData(val category: List<Category>)
data class Category(val _id:Double, val category_name:String, val sub_category_name:String, val price:Int)在这一行，我得到一个错误
val jsonData = gson.fromJson(body, CategoryJsonData::class.java)当我解析这个JSON时
{ "_id": "5b80393f7fca491488980fe1", "category_name": "electrical", "sub_category_name": "switches meters and fuses", "price": 300 }java.lang.NumberFormatException:无效的双精度："5b80393f7fca491488980fe1“
5b80393f7fca491488980fe1(_id)是由mongoose使用nodejs生成的。尝试访问API时显示此错误。

在您的JSON中，这是一个字符串"_id": "5b80393f7fca491488980fe1"
在您的类中，您将其定义为双val _id:Double
您需要将其更改为字符串，因为JSON值中包含非数字字符
