Question

我有两个API：一个是PUT请求，另一个是POST请求。这两个API都返回完全相同的JSON结构。在我的POST请求上一切都很好，我得到了正确的响应映射。但是在PUT请求中，使用完全相同的映射，响应不会映射。（Restkit无法找到匹配响应）。这是POST的代码（这很好）：

    // POST with no params
    GameRequestModel* requestModel = [[GameRequestModel alloc] init];
    requestModel.gameid = GAME_ID;

    // response
    RKResponseDescriptor *responseDescriptor =
    [RKResponseDescriptor responseDescriptorWithMapping:[SIAGameModel objectMapping]
                                                 method:RKRequestMethodPOST
                                            pathPattern:@"api/v1/games/mygame"
                                                keyPath:nil
                                            statusCodes:[NSIndexSet indexSetWithIndex:200]];

    // request
    RKObjectMapping *requestMapping = [RKObjectMapping requestMapping];
    [requestMapping addAttributeMappingsFromArray:@[GAME_ID_KEY]];

    // For any object of the model, serialize into an NSMutableDictionary using the given mapping
    RKRequestDescriptor *requestDescriptor = [RKRequestDescriptor requestDescriptorWithMapping:[requestMapping inverseMapping]
                                                                                   objectClass:[GameRequestModel class]
                                                                                   rootKeyPath:nil
                                                                                        method:RKRequestMethodPOST];

    // set response and request
    [self.objectManager addResponseDescriptor:responseDescriptor];
    [self.objectManager addRequestDescriptor:requestDescriptor];

    [self.objectManager postObject:requestModel
                              path:[NSString stringWithFormat:@"/api/v1/games/mygame?access_token=%@", accessToken]
                        parameters:nil
                           success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {

                               NSLog(@"mygame POST request succeeded");
                               [self getGameVideos:mappingResult.firstObject];

                           } failure:^(RKObjectRequestOperation *operation, NSError *error) {

                               NSLog(@"mygame POST request failed: %@", error);

                           }];

这是PUT请求，它没有映射到同一个映射，来自服务器的响应相同：

    // PUT with winning video id
    RoundRequestModel* roundRequestModel = [[RoundRequestModel alloc] init];
    roundRequestModel.selected = @"1";

    // response
    RKResponseDescriptor *responseDescriptor =
    [RKResponseDescriptor responseDescriptorWithMapping:[SIAGameModel objectMapping]
                                                 method:RKRequestMethodPUT
                                            pathPattern:@"api/v1/games/mygame"
                                                keyPath:nil
                                            statusCodes:[NSIndexSet indexSetWithIndex:200]];

    // request
    RKObjectMapping *requestMapping = [RKObjectMapping requestMapping];
    [requestMapping addAttributeMappingsFromArray:@[@"selected"]];

    // For any object of the model, serialize into an NSMutableDictionary using the given mapping
    RKRequestDescriptor *requestDescriptor = [RKRequestDescriptor requestDescriptorWithMapping:[requestMapping inverseMapping]
                                                                                   objectClass:[RoundRequestModel class]
                                                                                   rootKeyPath:nil
                                                                                        method:RKRequestMethodPUT];
    // set response and request
    [self.objectManager addResponseDescriptor:responseDescriptor];
    [self.objectManager addRequestDescriptor:requestDescriptor];

    NSString* putUrl = @"api/v1/games/mygame";
    putUrl = [putUrl stringByAppendingFormat:@"/%@?access_token=%@", appDelegate.gameId, accessToken];

    [self.objectManager putObject:roundRequestModel
                             path:putUrl
                       parameters:nil
                          success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {

                              NSLog(@"mygame PUT request succeeded");
                              [self getGameVideos:mappingResult.firstObject];

                          } failure:^(RKObjectRequestOperation *operation, NSError *error) {

                              NSLog(@"mygame PUT request failed: %@", error);

                          }];

感谢。

好的，得到了问题。当调用PUT请求时，url是不同的，因为我将游戏ID添加到url（而不是... / mygame现在是... / mygame / gameid），这应该是此调用的pathPattern。所以请求和响应pathPattern之间存在不匹配，因此错误......
