【问题描述】：

这是我的 JSON：link

这是我的映射器：

-(RKObjectManager *)mapContact
    RKObjectMapping* dataMapping = [RKObjectMapping mappingForClass:[Data class]];
    [dataMapping addAttributeMappingsFromDictionary:@
                                                      @"Data": @"app_data",
                                                      @"message": @"app_message",
                                                      @"status":@"app_status",
                                                      @"Success": @"app_success"
                                                      ];

    RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:dataMapping method:RKRequestMethodGET pathPattern:nil keyPath:@"" statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];

    RKEntityMapping* contactMapping = [RKEntityMapping mappingForEntityForName:@"Contact" inManagedObjectStore:managedObjectStore];
    contactMapping.identificationAttributes = @[@"con_id"];
    [contactMapping addAttributeMappingsFromDictionary:@
                                                                @"content": @"con_content",
                                                                @"id"     : @"con_id",
                                                                @"title"  : @"con_title",
                                                                @"language":@"con_language",
                                                                ];

    RKResponseDescriptor *responseDescriptor2 = [RKResponseDescriptor responseDescriptorWithMapping:contactMapping
                                                                                             method:RKRequestMethodGET
                                                                                        pathPattern:nil
                                                                                            keyPath:@"data.contentblock"
                                                                                        statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];

    NSArray *arrResponsDescriptor = [[NSArray alloc]initWithObjects:responseDescriptor,responseDescriptor2,nil];

    [objectManager addResponseDescriptorsFromArray:arrResponsDescriptor];
    return objectManager;

这是我的网络服务调用：

-(void)fetchContactOnCompletion:(myCompletion) compblock
    Mapper *mapper = [Mapper new];
    RKManagedObjectStore *store = [[ASLDataModel sharedDataModel] objectStore];
    NSManagedObjectContext *context = store.mainQueueManagedObjectContext;
    RKObjectManager *objectManager = [mapper mapContact];


    NSString *urlString = [NSString stringWithFormat:@"webservice/content/get/apikey/%@/language/%@/contentid/2",apikey,language];

    NSURLRequest *request = [objectManager requestWithObject:nil method:RKRequestMethodGET path:urlString parameters:nil];



    RKManagedObjectRequestOperation *operation = [objectManager managedObjectRequestOperationWithRequest:request managedObjectContext:context success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) 
        Data *data = [mappingResult.dictionary valueForKey:@""];
        if([data.app_status isEqualToNumber:@200])
            NSError *error = nil;
            BOOL success = [context  save:&error];
            if (!success) RKLogWarning(@"Failed saving managed object context: %@", error);
            NSError *saveError = nil;
            compblock(YES);
        else
            compblock(NO);
        
     failure:^(RKObjectRequestOperation *operation, NSError *error) 

    ];
    [objectManager enqueueObjectRequestOperation:operation];

我得到了这些错误：

2015-09-08 08:38:56.431 ASLTravel[17377:427756] D restkit.object_mapping:RKMapperOperation.m:433 Finished performing object mapping. Results: (null)

谁能帮我解决这个问题？我正在寻找这个问题几个小时......

非常感谢！

【参考方案1】：

Web 服务将您重定向到www.asl-travel.be，因此模式匹配器将永远找不到匹配项。更新基本 URL 或关闭重定向以解决此问题。

【讨论】：

我应该在基本 URL 中准确更改什么。因为我已经尝试过使用或不使用正斜杠？

您目前没有 www 部分
