使用休息套件第二次请求后的响应不正确

Question

我是restkit的新手，对此我有问题。我有一个restservice要办理入住手续。所以我打电话给我的restservice，请求"Put"。看起来像Put:http:/api/v1/locations/location/[location ID]/checkin？userId=[用户ID]。响应是一个，所以我称之为checkin对象。办理入住后，我将呼叫另一项服务（Get-Request）。但是get请求的新映射结果包括以前的签入对象。如何重置/擦除它？

[self.restHelper checkinUser:[NSNumber numberWithInt:USER_ID] forLocationID:self.selectedLocation success:successBlock failure:failureBlock];

映射：

- (void)checkinUser:(NSNumber*) userID forLocationID:(NSNumber *)locationID success:(void (^)(RKObjectRequestOperation *, RKMappingResult *))success failure:(void (^)(RKObjectRequestOperation *, NSError *))failure{
RKObjectManager *objectManager = [RKObjectManager sharedManager];
RKObjectMapping *userCheckinMapping = [RKObjectMapping mappingForClass:[CheckIN class]];
[userCheckinMapping addAttributeMappingsFromDictionary:@{
 @"locationFullname" : @"locationFullname",
 @"userNameCityCountry" : @"userNameCityCountry",
 @"success" : @"success",
 }];
RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:userCheckinMapping pathPattern:nil keyPath:@"" statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];
[objectManager addResponseDescriptor:responseDescriptor];
NSString *path = [NSString stringWithFormat:@".../api/v1/locations/location/%@/checkin?userId=%@", locationID,userID];
[objectManager putObject:nil path:path parameters:nil success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
    success(operation, mappingResult);
} failure:^(RKObjectRequestOperation *operation, NSError *error) {
    failure(operation,error);
}];    

}

下一个电话是这样的：

 -(void)getTracksForLocation:(NSNumber *)locationID withType:(NSString*) type success:(void (^)(RKObjectRequestOperation *, RKMappingResult *))success failure:(void (^)(RKObjectRequestOperation *, NSError *))failure{
RKObjectManager *objectManager = [RKObjectManager sharedManager];
RKObjectMapping *trackResultsMapping = [RKObjectMapping mappingForClass:[RESTTracksResult class]];
[trackResultsMapping addAttributeMappingsFromDictionary:@{
 @"id" : @"ID",
 @"cued" : @"cued",
 @"marked" : @"marked",
 @"playing": @"playing",
 @"played": @"played",
 @"creditBidSum": @"creditBidSum",
 }];
RKObjectMapping *trackMapping = [RKObjectMapping mappingForClass:[RESTTrack class]];
[trackMapping addAttributeMappingsFromDictionary:@{
 //@"id" : @"ID",
 @"name" : @"name",
 @"artistName" : @"artistName",
 @"genre": @"genre",
 @"length": @"length",
 }];
RKRelationshipMapping* relationShipMapping = [RKRelationshipMapping relationshipMappingFromKeyPath:@"track"
                                                                                         toKeyPath:@"track"
                                                                                       withMapping:trackMapping];
[trackResultsMapping addPropertyMapping:relationShipMapping];

RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:trackResultsMapping pathPattern:nil keyPath:@"results" statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];
[objectManager addResponseDescriptor:responseDescriptor];
NSDictionary *trackDictionary = @{ @"type": type};
NSString *path = [NSString stringWithFormat:@".../api/v1/locations/location/%@/tracks", locationID ];
[objectManager getObjectsAtPath:path parameters:trackDictionary success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
    success(operation, mappingResult);
} failure:^(RKObjectRequestOperation *operation, NSError *error) {
    failure(operation,error);
}];

}

希望你能帮助我，蒂！我也试过删除缓存，但没有成功！

您做错了一些事情，这意味着当您进行第二次调用时，第一次调用中的所有配置都被用来尝试理解第二次响应。

1.

当您使用对象管理器时，您应该设置基本URL。你可能已经在做了，很难说。然后，无论何时指定路径，它都应该相对于该基准。

2.

创建路径时，不要添加参数。这就是put和get方法中parameters参数的作用。

3.

如果您使用的是sharedManager，那么您应该一次性完成所有映射配置。不要每次调用方法时都添加额外的映射。

4.

创建响应描述符时，请设置路径模式和密钥路径。这是你的主要问题。如果您不设置它们，RestKit将始终尝试使用机架映射来处理每个响应。这将导致您在映射结果中获得意外的对象，可能会赢得部分信息。
