我需要制作来自 User 类的两种不同类型的 POST。

//JSON Type A
{
    "password":"12345",
    "email":"test@gmail.com"
}

//JSON Type B
{
   "user":{
      "Password":"12345",
      "Email":"sample@gmail.com"
   }
}

我试图创建两个请求描述符并将它们添加到我的对象管理器但是我得到了错误

“无法为与现有请求描述符相同的对象类添加请求描述符。”

我的代码

@interface User : NSObject

@property (nonatomic, retain) NSString * userID;
@property (nonatomic, retain) NSString * email;
@property (nonatomic, retain) NSString * password;
@property (nonatomic, retain) NSString * firstName;
@property (nonatomic, retain) NSString * lastName;

@end

- (void)setupUserMapping:(RKObjectManager *)objectManager {

    // Setup user response mappings
    RKObjectMapping *userMapping = [RKObjectMapping mappingForClass:[User class]];
    [userMapping addAttributeMappingsFromDictionary:@{
     @"ID" :@"userID",
     @"Email" : @"email",
     @"Password" : @"password",
     @"FirstName" : @"firstName",
     @"LastName" : @"lastName",
     }];


    RKResponseDescriptor *responseDescriptorAuthenticate = [RKResponseDescriptor responseDescriptorWithMapping:userMapping
                                                                                       pathPattern:@"/Authenticate"
                                                                                           keyPath:nil
                                                                                       statusCodes:[NSIndexSet indexSetWithIndex:200]];


    RKResponseDescriptor *responseDescriptorRegister = [RKResponseDescriptor responseDescriptorWithMapping:userMapping
                                                                                                   pathPattern:@"/Register"
                                                                                                       keyPath:nil
                                                                                                   statusCodes:[NSIndexSet indexSetWithIndex:200]];
    [objectManager addResponseDescriptor:responseDescriptorRegister];
    [objectManager addResponseDescriptor:responseDescriptorAuthenticate];

    // Setup user request mappings
    RKObjectMapping* userRequestMappingForRegister = [RKObjectMapping requestMapping];
    [userRequestMappingForRegister addAttributeMappingsFromDictionary:@{
     @"email" : @"Email",
     @"password" : @"Password",
     @"firstName" : @"FirstName",
     @"lastName" : @"LastName",
     }];
    RKRequestDescriptor *requestDescriptorForRegister = [RKRequestDescriptor requestDescriptorWithMapping:userRequestMappingForRegister objectClass:[User class] rootKeyPath:@"user"];


    RKObjectMapping* userRequestMappingForAuthenticate = [RKObjectMapping requestMapping];
    [userRequestMappingForAuthenticate addAttributeMappingsFromDictionary:@{
     @"userID" :@"ID",
     @"email" : @"email",
     @"password": @"password"
     }];
    RKRequestDescriptor *requestDescriptorForAuthenticate = [RKRequestDescriptor requestDescriptorWithMapping:userRequestMappingForAuthenticate objectClass:[User class] rootKeyPath:nil];

    [objectManager addRequestDescriptor:requestDescriptorForRegister];
    [objectManager addRequestDescriptor:requestDescriptorForAuthenticate];
}

有谁知道如何在不为这些请求创建单独的类的情况下解决这个问题？

任何帮助表示赞赏。

谢谢。

您可以使用动态映射来切换序列化行为。如果这是一个足够普遍的问题，我们可以想象将路径匹配添加到请求描述符。我只是没有对这样的功能提出很多要求。

有一个如何在单元测试中将动态映射与请求一起使用的示例：https ://github.com/RestKit/RestKit/blob/master/Tests/Logic/ObjectMapping/RKObjectParameterizationTest.m#L495-L534

对于多个请求描述符，我声明了一个新模型类，其数据成员与前一个相同，然后在添加请求描述符时引用它而不是前一个，如下所示。 

    RKObjectMapping *mapping = [RKObjectMapping mappingForClass:[CMAGoogleUserDataModel class]];

这里新创建的类是“CMAGoogleUserDataModel”

注意：我不确定它是否是优化的，但它确实解决了我的用例。
