在Restkit 0.2中为给定类添加两个请求描述符 [英] Adding two request descriptors for a given class in Restkit 0.2

问题描述

我需要从User类中制作两种不同类型的POST。

I need to make two different types of POST coming from the User class.

//JSON Type A
{
    "password":"12345",
    "email":"[e-mail]"
}

//JSON Type B
{
   "user":{
      "Password":"12345",
      "Email":"[e-mail]"
   }
}

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收到了错误

I've tried to make two request descriptors and adding them to my object manager however I get the error

无法为
现有请求描述符添加同一对象类的请求描述符。

"Cannot add a request descriptor for the same object class as an existing request descriptor."

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];
}

有没有人知道如何解决这个问题而不为这些创建一个单独的类要求？

Does anyone know how I can solve this problem without creating a separate class for these requests?

感谢任何帮助。

谢谢。

推荐答案

您可以使用动态映射切换序列化行为。如果这是一个很常见的问题，我们可以想象添加路径匹配到请求描述符。我对这样的功能没有太多的要求。

You can use a dynamic mapping to switch the serialization behaviors. If this is a common enough issue, we could conceivably add path matching to the request descriptor. I just have not had a ton of requests for such a feature.

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

There is an example of how to use the dynamic mapping with a request in the unit tests: https://github.com/RestKit/RestKit/blob/master/Tests/Logic/ObjectMapping/RKObjectParameterizationTest.m#L495-L534
