ios – 在Restkit 0.2中为给定的类添加两个请求描述符

概述我需要从User类中提供两种不同类型的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 我需要从User类中提供两种不同类型的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其添加到我的对象管理器,但是我收到错误

“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,而不需要为这些请求创建一个单独的类？

任何帮助是赞赏.

谢谢.

解决方法 您可以使用动态映射来切换序列化行为.如果这是一个很常见的问题,我们可以想象地将路径匹配添加到请求描述符中.我只是没有这么多的要求.

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