在Restkit 0.2中为给定类添加两个请求描述符

Question

我需要从User类中创建两种不同类型的POST.

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

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

我试图制作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];
}

有没有人知道如何在不为这些请求创建单独的类的情况下解决此问题？

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,我们可以想象地将路径匹配添加到请求描述符.我对这样的功能没有太大的要求.

有一个如何在单元测试中使用动态映射和请求的示例:https://github.com/RestKit/RestKit/blob/master/Tests/Logic/ObjectMapping/RKObjectParameterizationTest.m#L495-L534
