请帮忙。我对 RestKit 很陌生，并且几天来一直在努力使用 RestKit .20.3 成功执行相当直接的 POST。我遵循所有各种示例和说明，并使用了 Alexander Edge 教程的一部分以及 RestKit GitHub 示例和文档，但无济于事。有人可以快速浏览一下我的代码并给我一些提示，告诉我如何使用 RestKit .20.3 执行成功的 POST 吗？我怀疑我的最后一行代码有问题，因为我的 postObject 是“nil”，但是我不确定。任何提示或建议将不胜感激。

顺便说一句：我在调试日志中收到的错误是“（400-499）中的预期状态代码，得到 204”

这是我更新的代码。我做了所有建议的模组，现在我收到以下错误：got 500" UserInfo=0x95c7bd0 {NSLocalizedRecoverySuggestion=Error 500: javax.servlet.ServletException: org.codehaus.jackson.map.JsonMappingException: Can not find a deserializer for non -concrete Map type [map type; class javax.ws.rs.core.MultivaluedMap, [simple type, class java.lang.String] -> [simple type, class java.lang.String]] 关于修复的任何想法？

post 对象不能是nil，重点是您正在尝试发布该对象。204 响应基本上是确认服务器收到了您的请求但没有工作要做。

您使用的路径不应是完整的 URL。您配置管理器，managerWithBaseURL因此路径应该是getDataURL.

你得到"Expected status code in (400-499), got 204"是因为你已经配置了一个很好的通用错误处理响应描述符（适用于任何东西，因为路径模式是nil. 你还应该为成功案例指定一个响应描述符。你创建ticketParentMapping但从未实际将它用于任何事情......

如上所述，POST 意味着您传递的对象将根据 RequestDescriptor 序列化到您指向的 URL。

零将不起作用。此外，您还没有设置 RequestDescriptor
