您可能需要创建一个数据类来包装

AuthorizeSessionResponse

类

比如：

data class AuthorizeSessionResponseWrapper (var authorizeSessionResponse: AuthorizeSessionResponse)

---

你能解释一下这个类应该放在哪里吗。很抱歉问这个问题，但我是Android新手Development@TolgahanTutar根据你发布的回复，你不需要这样做this@AdityaKurkure好的，我明白了。但我还是不知道哪里出了错。我被它卡住了你在日志中得到了想要的响应吗。您可以通过筛选日志中的单词http进行检查。No。我没有从URL得到任何响应。你能再次检查你的JSON吗？你确定这是正确的模式吗？当我从swagger运行JSON时，我意识到我的JSON是正确的。但是当我使用邮递员查看回复时，我得到的代码中充满了HTML@TolgahanTutarurl抛出错误而不是成功响应。您应该检查改装代码中的响应代码
