ios - 使用restkit api objective-c 调用Web服务时出错

我正在尝试调用网络服务并上传图片，

映射有问题，我花了好几个小时都没有成功。我得到的错误是:

Error Domain=org.restkit.RestKit.ErrorDomain Code=1001 "No mappable object representations were found at the key paths searched." UserInfo={NSLocalizedDescription=No mappable object representations were found at the key paths searched., NSLocalizedFailureReason=The mapping operation was unable to find any nested object representations at the key paths searched: user The representation inputted to the mapper was found to contain nested object representations at the following key paths: message, success This likely indicates that you have misconfigured the key paths for your mappings., keyPath=null, DetailedErrors=( )}

还有调用网络服务的方法

Best Answer-推荐答案

此错误告诉您 user 路径中没有可用的内容。例如，如果您的响应是 JSON，则没有名为 user 的根键，只有 message 和 success:

{ "user": "<- 这个键不存在", "message": "<- 这里有东西", "success": "<- 这里也有东西" }

您很可能需要将 keyPath 从 user 更改为 success.user。
