谢谢你的回复。我尝试了你的建议，然后又出现了另一个错误。请检查我帖子中的更新。打印回复、状态代码和正文，可能url/数据/标题不正确。我已经更新了我的帖子，请检查。当我打印body.toJSON（）时
它显示了一些明显不正确的地方。这是因为我对模型使用了命名参数
，并使用flatter-packages-pub-run-build\u-runner-build
来构建something.g.dart
类吗？我这样做是因为这样我就可以只填充模型类的必需字段，而不是填充n执行post
。对不起，我不明白。你是指我的user.dart
类吗？我可以看到我有Map-to-json（）=>$UserToJson（this）；
。你的建议是用你的代码替换它？是的，因为你需要像json一样的用户语言和用户权限
