在没有嵌套KVC的情况下映射来自POST的响应

Question

我正在尝试将属性映射到RESTKit中的一个类而没有嵌套的KVC，并且没有太多运气，即使响应包含值，我也会继续为我的值获取nil。

我已经阅读了对象映射手册并尝试了没有路径模式的路径模式等。有没有人有任何见解？

来自服务器的请求和响应

正在映射的类

RKObjectMapping *notifyMapping = [RKObjectMapping mappingForClass:[WTFGameNotification class]];

[notifyMapping addAttributeMappingsFromDictionary:
 @{
 @"result" : @"result",

 }];

RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:notifyMapping
                                                                                        method:RKRequestMethodGET

@interface WTFGameNotification : NSObject

似乎如果你试图从POST映射响应，这是应该使用的方法和语法。

+ ( void )SendNotification:(GameInfo*)gameInfo withMessage:(NSString*)message forView:(UIViewController*)view
{
    WTFGameNotification *_wtfGameNotif = [WTFGameNotification Create];

    [_wtfGameNotif setTo:[gameInfo opponentWTFID]];
    [_wtfGameNotif setFrom:[PlayerWTFInfo Load]._wtfID];
    [_wtfGameNotif setGameID:[gameInfo gameID]];
    [_wtfGameNotif setMessage:message];

    if ([_wtfGameNotif to] && [_wtfGameNotif gameID])
    {
        RKObjectRequestOperation *operation = [[RKObjectManager sharedManager] appropriateObjectRequestOperationWithObject:_wtfGameNotif
                                                                                                                    method:RKRequestMethodPOST
                                                                                                                      path:nil
                                                                                                                parameters:nil];
        RFResponse *r1 = [RFResponse new];
        operation.targetObject = r1;

        [operation setCompletionBlockWithSuccess:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult)
        {
            if (r1.result.integerValue != 0)
            {
                [Utilities FacebookPostWithResult:@{@"fbId": r1.notify}];
            }
        }
        failure:^(RKObjectRequestOperation *operation, NSError *error)
        {
            DDLogError(@"POST REQUEST FAILED IN CONFIRMFOTOVC : %@",[error description]);

             if (view)
             {
                 [LoadingView PopToRootShutterCloseOnView:view willOpen:YES];
             }
        }];

        [operation start];

    }
    else
    {
        DDLogInfo(@"NO PLAYER ID");
    }
}

Answer 2

如果要将对象发布到服务器，那么您拥有的响应描述符将不匹配，因为您将其链接到带有method:RKRequestMethodGET的GET。您需要将其更改为method:RKRequestMethodPOST。

使用@"notify/player"的路径模式时，基本网址应设置为https://api.myURL.com/api/0_0_1/，但看起来这不是一个问题。
