将没有root密钥的对象映射到动态url？

Question

我试图映射以下对象：

{"walletAccepted":false,"creditCardTypesAccepted":["visa","mastercard","discover","americanexpress"],"paypalAccepted":false} 

要具有相同属性的对象。但是，ResourcePath是动态的，因为它沿着/ paymentmethods/zone /行：internalZoneCode

我在映射时所做的每一次尝试总是以“映射期间遇到的错误：无法找到对象映射对于keyPath：''“

我认为问题是没有root密钥/密钥路径。我也尝试没有运气以下：

RKURL *rkUrl = [RKURL URLWithBaseURL:[RKClient sharedClient].baseURL resourcePath:[NSString stringWithFormat:@"/paymentoptions/zone/%@", zoneNumber]]; 
RKObjectLoader* loader = [[RKObjectLoader alloc] initWithURL:rkUrl mappingProvider:[RKObjectManager sharedManager].mappingProvider]; 
loader.method = RKRequestMethodGET; 
loader.delegate = self; 

loader.objectMapping = [[RKObjectManager sharedManager].mappingProvider objectMappingForClass:[PMZonePaymentMethods class]]; 
[loader send]; 

Answer 1

我发现做到这一点的方法是配置的映射，并添加映射对象管理没有一个关键路径或resourcek

所以像这样：

RKObjectMapping* zonePaymentMethodsMapping = [RKObjectMapping mappingForClass:[PMZonePaymentMethods class]]; 
[zonePaymentMethodsMapping mapKeyPath:@"walletAccepted" toAttribute:@"walletAvailable"]; 
[zonePaymentMethodsMapping mapKeyPath:@"creditCardTypesAccepted" toAttribute:@"cards"]; 
[zonePaymentMethodsMapping mapKeyPath:@"paypalAccepted" toAttribute:@"paypalAvailable"]; 

[[RKObjectManager sharedManager].mappingProvider addObjectMapping:zonePaymentMethodsMapping]; 

，并用它来发出请求：

RKURL *rkUrl = [RKURL URLWithBaseURL:[RKClient sharedClient].baseURL resourcePath:[NSString stringWithFormat:@"/paymentoptions/zone/%@", zoneNumber]]; 
RKObjectLoader* loader = [[RKObjectLoader alloc] initWithURL:rkUrl mappingProvider:  [RKObjectManager sharedManager].mappingProvider]; 
loader.method = RKRequestMethodGET; 
loader.delegate = self; 

loader.objectMapping = [[RKObjectManager sharedManager].mappingProvider objectMappingForClass:[PMZonePaymentMethods class]]; 
[loader send];
