ios - RestKit - 错误域代码 1001

Question

好吧，我已经复习了该站点上几乎所有其他问题，但无济于事。

这是我从 REST 服务返回的 JSON:

{
 "errors" :     {};
 "result" :     {
    "messagebody" : "Hello!";
    "timestamp" : "2014-08-21T04:12:28.4689099+00:00";
 };
 "success" :    {};
}

我正在尝试通过 RestKit v0.20.3 提取结果对象

这是我配置/执行的代码块:

- (void) configureRestKit
{

NSURL *cminstance = [NSURL URLWithString:@"http://<domain>"];
AFHTTPClient *cmclient = [[AFHTTPClient alloc] initWithBaseURL:cminstance];

RKObjectManager *objmgr = [[RKObjectManager alloc] initWithHTTPClient:cmclient];

RKObjectMapping *messageMap = [RKObjectMapping mappingForClass:[Message class]];
[messageMap addAttributeMappingsFromDictionary:@{ @"messagebody" : @"messagebody", @"timestamp": @"timestamp"}];
messageMap.forceCollectionMapping = YES;
RKResponseDescriptor *descriptor =
[RKResponseDescriptor
 responseDescriptorWithMapping:messageMap
 method:RKRequestMethodGET
 pathPattern:@"/v1/app/e51cb2dd24af47a49232b942210e758d/text?f=test"
 keyPath:@"result"
 statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];
[objmgr addResponseDescriptor:descriptor];
}

- (IBAction)helloButtonClicked:(id)sender {

[[RKObjectManager sharedManager].HTTPClient setDefaultHeader:@"X-App-ApiKey" value:@"2c130c75dc9f4c2c8ef7c8753e8b7c56"];
NSLog(@"ResponseDescriptors %@", [[RKObjectManager sharedManager] responseDescriptors]);
[[RKObjectManager sharedManager] getObjectsAtPath:@"/v1/app/e51cb2dd24af47a49232b942210e758d/text?f=test" parameters:nil success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {

    _Response.text = [mappingResult.dictionary objectForKey:@"messagebody"];

} failure:^(RKObjectRequestOperation *operation, NSError *error)
 {
     _Response.text = @"Something went wrong.";
 }];
}

这是跟踪的错误:

2014-08-21 00:12:30.653 The-App[13924:3707] E restkit.network:RKObjectRequestOperation.m:208 GET 'http:///v1/app/e51cb2dd24af47a49232b942210e758d/text?f=test' (200 OK / 0 objects) [request=2.7297s mapping=0.0000s total=2.7365s]: error=Error Domain=org.restkit.RestKit.ErrorDomain Code=1001 "No response descriptors match the response loaded."

这里有关于如何排除故障的任何想法吗？几个小时以来，我一直在努力解决这个问题，而谷歌并不是我的 friend 。

编辑响应描述符

2014-08-22 10:41:21.580 Apprenda-CloudMine-App[10987:60b] ResponseDescriptors (
"<RKResponseDescriptor: 0x17826c180 method=(GET) pathPattern=/v1/app/e51cb2dd24af47a49232b942210e758d/text?f=test keyPath=result statusCodes=200-299 : <RKObjectMapping:0x17826bfc0 objectClass=Message propertyMappings=(\n    \"<RKAttributeMapping: 0x1780499f0 timestamp => timestamp>\",\n    \"<RKAttributeMapping: 0x17804cf30 messagebody => messagebody>\"\n)>>"

)

谢谢!-克里斯

该错误表明您的请求和响应描述符之间的路径不匹配。这很微妙，错误消息中的 (0) 响应描述符 还向我表明该路径没有响应描述符。有关 RestKit 路径不匹配的错误消息的更多信息，请参阅 this GitHub 问题。

那你为什么会遇到路径不匹配？毕竟，请求中的路径与响应描述符中的路径完全相同。看起来您的问题很可能是响应描述符路径中指定的 GET 参数。您需要从响应描述符路径中删除 get 参数，因为它在技术上不是路径的一部分。

应该是下面的内容。

[RKResponseDescriptor
 responseDescriptorWithMapping:messageMap
 method:RKRequestMethodGET
 pathPattern:@"/v1/app/e51cb2dd24af47a49232b942210e758d/text"
 keyPath:@"result"
 statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];

感谢Flaviu Simihaian为了实现这一点。
