Ios 使用restkit api目标c调用web服务时出错

我正在尝试调用web服务并上传图像

映射中有一个问题，我花了很多时间都没有成功。我得到的错误是：

Error Domain=org.restkit.restkit.ErrorDomain Code=1001“不可映射 在搜索的关键路径中找到了对象表示。“ UserInfo={NSLocalizedDescription=没有可映射的对象表示形式 在搜索的关键路径中找到。NSLocalizedFailureReason= 映射操作找不到任何嵌套对象表示形式 在搜索的关键路径处：用户输入到 发现映射程序包含位于 以下关键路径：message，success这可能表示您 已错误配置映射的键路径。键路径=null， 详细错误=（）}

还有调用web服务的方法

此错误告诉您，

用户路径上没有可用的内容。例如，如果您的响应是JSON，则没有名为
user
的根键，只有
message
和
success
：

“用户”：
