Restkit映射 - 没有响应描述符匹配加载的响应

我是RestKit和Objective C的新手。我试图从带有RestKit的Web服务中检索数据。我已经完成了映射，但一些我得到的错误，它无法找到匹配的响应。由于JSON格式没有密钥，因此我使用的是没有KVC的映射。Restkit映射 - 没有响应描述符匹配加载的响应

这里是映射实现

+(RKObjectMapping *)venueMapping { 
    RKObjectMapping *mapping = [RKObjectMapping mappingForClass:[venue class]]; 
    NSDictionary *mappingDictionary = @{@"name":@"name"}; 
    [mapping addAttributeMappingsFromDictionary:mappingDictionary]; 

    return mapping; 
}

我只有一个值，想看看是否有任何匹配。下面是回复描述符

-(void) loadVenue:(void (^)(venue *))success failure:(void (^)(RKObjectRequestOperation *, NSError *))failure{ 

    RKLogConfigureByName("RestKit/ObjectMapping", RKLogLevelTrace); 
    [self getObjectsAtPath:@"venue" parameters:nil success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult){ 

    if(success){ 
     venue *venues = (venue *)[mappingResult.array firstObject]; 
     success(venues); 
    } 

    }failure:^(RKObjectRequestOperation *operation, NSError *error){ 
     if(failure){ 
      failure(operation,error); 
    } 
}]; 

} 

- (void) setupResponseDescriptors { 
[super setupResponseDescriptiors]; 

RKResponseDescriptor *authenticatedUserResponseDescriptors = [RKResponseDescriptor responseDescriptorWithMapping:[MappingProvider venueMapping] method:RKRequestMethodGET pathPattern:@"venue" keyPath:@"" statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)]; 
[self addResponseDescriptor:authenticatedUserResponseDescriptors]; 
}

我一直在阅读文档并尝试各种方法，但我仍然没有解决这个问题。任何人有任何想法？

附加是一个示例JSON返回。

(
    { 
    coverType = "<null>"; 
    description = ""; 
    name = "McDonald"; 
    priv = 1; 
    rates =(); 
    }, 
    { 
    coverType = "<null>"; 
    description = ""; 
    name = "My House"; 
    priv = 1; 
    rates =(); 
    }, 
)

新增追踪日志

我试图把整个映射在代码中，这不是正确映射情况。但似乎它仍然无法正常工作。不过，我在调试期间发现了这个错误，** NSUnderlyingError：摘要字符串解析错误**。这是否意味着我的映射声明有一些问题？ – greenhatman

进一步调试后，似乎baseURL不匹配。不太确定发生了什么事。将尝试进一步调试 – greenhatman

您能否为响应添加跟踪日志输出？并将响应描述符键路径更改为'nil'。 – Wain
