Question

我正在尝试在我的响应正文中序列化 SyncRewardDataRequestModel 。＆＃34;的 an_id ＆＃34;序列化很好。但是，NSArray中的 SyncRewardDataInputModel 对象始终序列化为空的NSArray。我已经确认我在NSArray中传递了正确的值 - 有人看到我的映射有什么不正确吗？

类：

@interface SyncRewardDataInputModel : NSObject
@property (nonatomic,copy) NSNumber *test_id;
@end

@interface SyncRewardDataRequestModel : NSObject
@property (nonatomic,strong) NSArray *syncRewardDataInputs;
@property (nonatomic,copy) NSNumber *an_id;
@end

以下是我的回复描述符：

     //Populate mapping
 RKObjectMapping *requestMapping = [RKObjectMapping requestMapping]; // objectClass == NSMutableDictionary
[requestMapping addAttributeMappingsFromDictionary:@{@"an_id": @"an_id"}];


RKObjectMapping *syncRewardDataInputsMapping = [RKObjectMapping mappingForClass:[SyncRewardDataInputModel class]];
[syncRewardDataInputsMapping addAttributeMappingsFromDictionary:@{@"test_id":   @"test_id"}];

//Combine
RKRelationshipMapping *arrayRelation = [RKRelationshipMapping relationshipMappingFromKeyPath:@"syncRewardDataInputs" toKeyPath:@"downloadCardResponseDTOs" withMapping:syncRewardDataInputsMapping];

[requestMapping addPropertyMapping:arrayRelation];

//Put it in a request
 RKRequestDescriptor *requestDescriptor = [RKRequestDescriptor requestDescriptorWithMapping:requestMapping objectClass:[SyncRewardDataRequestModel class] rootKeyPath:nil method:RKRequestMethodAny];

return requestDescriptor;

这一行：

RKObjectMapping *syncRewardDataInputsMapping = [RKObjectMapping mappingForClass:[SyncRewardDataInputModel class]];

应该是：

RKObjectMapping *syncRewardDataInputsMapping = [RKObjectMapping requestMapping];

因为对于请求，您总是尝试映射到NSMutableDictionary，以便可以从中生成JSON以进行传输。

通常，您将拥有一个用于接收数据的映射，链接到响应描述符，您可以使用inverseMapping来生成用于请求描述符的映射。
