iOS 应用因错误而超时而不是对其进行处理

Question

在 RestKit 应用程序中，我正在使请求和响应正常工作，但现在我正在尝试添加错误处理。我正在按照 RestKit readme 中的示例和来自网络的类似示例进行操作，但是运行出现了一些奇怪的行为。

错误映射添加

// Error JSON looks like {"errors": "Some Error Has Occurred"}
RKObjectMapping *errorMapping = [RKObjectMapping mappingForClass:[RKErrorMessage class]];
// The entire value at the source key path containing the errors maps to the message
[errorMapping addPropertyMapping:[RKAttributeMapping attributeMappingFromKeyPath:nil toKeyPath:@"errorMessage"]];
NSIndexSet *statusCodes = RKStatusCodeIndexSetForClass(RKStatusCodeClassClientError);
// Any response in the 4xx status code range with an "errors" key path uses this mapping
RKResponseDescriptor *errorDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:errorMapping method:RKRequestMethodAny pathPattern:nil keyPath:@"errors" statusCodes:statusCodes];

[objectManager addResponseDescriptor:errorDescriptor];

当我让我的服务模拟错误而不是 returning 数据时，会发生以下情况。我的服务响应是

HTTP/1.1 401 Unauthorized
Server: ASP.NET Development Server/10.0.0.0
Date: Tue, 26 May 2015 19:01:21 GMT
X-AspNet-Version: 4.0.30319
Cache-Control: private
Content-Type: application/json; charset=utf-8
Connection: Close

{"errors":"This is a test exception"}

之后连接关闭。然而，在客户端，getObjectsAtPath: 的失败块不会立即执行。相反，该函数等待超时并且不会 return 一个错误对象。错误是 [已更新。替换为包括跟踪日志记录的日志]:

很明显状态 401 得到了传达（第二个错误），但有些东西让 RestKit 等待更多数据。这种行为的原因可能是什么？一些错误配置？服务响应格式是否错误？错误映射有问题吗？

Answer 1

在服务端，发送数据后连接没有关闭。

进行适当的更改后，应用程序按预期处理了错误信息。谢谢，Wain，为我指明了正确的方向。
