Iphone 在RestKit 0.20.3中执行objectPost时出现错误204

请帮忙。我对RestKit非常陌生，几天来一直在努力使用RestKit.20.3成功执行一篇相当直截了当的文章。我遵循了所有不同的示例和说明，并使用了Alexander Edge教程的一部分以及RestKit GitHub示例和文档，但均无效。有没有人能快速浏览一下我的代码，并告诉我如何使用RestKit.20.3成功完成一篇文章？我怀疑我的最后一行代码是错误的，因为我的postObject是“nil”，但我只是不确定。如有任何提示或建议，将不胜感激

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

}

这是我的更新代码。我做了所有建议的mod，现在我得到了以下错误：get 500“UserInfo=0x95c7bd0{nsLocalizedRecoverysSuggestion=error 500:javax.servlet.ServletException:org.codehaus.jackson.map.JsonMappingException:找不到非具体映射类型的反序列化程序[map type；class javax.ws.rs.core.MultivaluedMap，[简单类型，类java.lang.String]->[简单类型，类java.lang.String]] 有什么解决办法吗

post对象不能是

nil

，关键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。您使用

managerWithBaseURL

配置管理器，因此该路径应是

getDataURL

上的附加部分

---

您在（400-499）中获得了预期的状态代码，在（400-499）中获得了204“，因为您已经配置了一个良好的通用错误处理响应描述符（适用于任何对象，因为路径模式为

nil

。您还应该为成功案例指定响应描述符。您创建

ticketParentMapping

，但从未实际将其用于任何对象…

如上所述，POST意味着您正在传递的对象将根据请求描述符进行序列化您指向的URL

零是行不通的。

---

另外，您还没有设置RequestDescriptor对我来说有意义。我认为，因为我是通过HTTPClient设置在代码顶部设置请求头的。因此，我添加了一个名为“RequestInquiry”的新类"它包含我的REST服务作为请求的一部分所期望的所有属性，然后将该对象添加到objectPost参数中，但是，我仍然得到一个204错误代码。我也接受了您的建议并修复了URL，但仍然没有成功。ticketParentMapping稍后将在我的代码中使用。我非常感谢您的快速且信息丰富的响应nse。再次感谢。我将继续研究并发布响应。您为

RequestInquiry

和关联的请求描述符创建了一个映射？使用RKObjectManager参考指南中的示例，我创建了一个名为RequestInquiry的.h和.m类文件，并将参数创建为类中的属性。然后我创建了一个对象（请求查询）在基于RequestInquiry的代码中，将属性设置为我的REST服务期望的值，然后通过postObject:RequestInquiry传递对象。同样基于@tekstop下面的注释，我创建了一个带有映射的RequestDescriptor。如果有帮助的话，我可以重新发布我的代码。进行了一些突破，并将我的请求描述符拉直d out。但是，我现在收到下面的错误。关于解决方案的任何建议。错误：NSLocalizedDescription=预期的内容类型{（“应用程序/x-www-form-urlencoded”，“应用程序/json”）}，获取文本/plain，AFNetworkingOperationFailingURLResponseErrorKey=}更新问题中的代码。看起来服务器返回了错误的类型。是否设置了Accept标头？我相信我已经纠正了在postObject中使用nil的问题，并且我也采纳了您的建议，创建了RequestDescriptor（很好的调用）但是，仍然得到204错误代码。非常感谢您的快速和有用的响应。如果您能想到我做错了什么，请告诉我。问题解决了。在将日志中出现的每个标题参数输入到WizTools后，我发现Accept参数被设置为“application/x-www-form-urlencoded”通过使用manager setAcceptHeaderWithMIMEType:@“application/x-www-form-urlencoded”]；一旦我注释掉该语句，我就开始得到200响应代码。
