Question

请帮忙。我是RestKit的新手，并且几天来一直在努力使用RestKit .20.3成功执行一个相当直接的POST。我遵循所有各种样本和说明，并使用了Alexander Edge的教程和RestKit GitHub示例和文档的一部分无济于事。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？我怀疑我的最后一行代码是错误的，因为我的postObject是“nil”但是，我只是不确定。任何提示或建议将不胜感激。

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

这是我更新的代码。我做了所有的建议mods，现在我收到以下错误：得到500“UserInfo = 0x95c7bd0 {NSLocalizedRecoverySuggestion =错误500：javax.servlet.ServletException：org.codehaus.jackson.map.JsonMappingException：找不到非解串器-concrete Map type [map type; class javax.ws.rs.core.MultivaluedMap，[simple type，class java.lang.String] - ＆gt; [simple type，class java.lang.String]] 关于修复的任何想法？

Answer 1

帖子对象不能是nil，重点是你试图发布该对象。 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。

您使用的路径不应该是完整的网址。您可以使用managerWithBaseURL配置管理器，因此路径应该是getDataURL上的附加部分。

你得到"Expected status code in (400-499), got 204"，因为你已经配置了一个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。创建ticketParentMapping但从未实际使用它......

Answer 2

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

无效。此外，您尚未设置RequestDescriptor

在RestKit 0.20.3中执行objectPost时出错204
