实体类

Gson解析

val responseString = getResponseString(response)  得到后台返回的加密数据
val goon = Gson() 实例化Gson
val toJson = goon.fromJson(responseString, UserBean::class.java) 解析资源实体类
val message1 = toJson.message  拿到message
val rep = message1.replace("[\\s*\t\n\r]".toRegex(), "")  转译
val fromContent = Base64Utils.getFromBase64(rep)   解密得到解码的数据对象
print(fromContent) 输出

问题点get不到任何属性值
