将没有根密钥的对象映射到动态URL？

Question

我正在尝试映射以下对象：

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

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

一致。

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keyPath的对象映射：''”

我认为问题在于没有根密钥/密钥路径。我也试过以下但没有运气：

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];

我发现实现它的方法是配置映射，并将映射添加到没有密钥路径或资源的对象管理器

所以这样：

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];

并使用它来发出请求：

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];
