Question

所以，我是第一次发送POST请求。我正在映射类，正如我想的那样，从文档中读取它将以这种方式工作：

Init RK：

- (void)initRK{
    if(!manager){
        manager = [RKObjectManager managerWithBaseURL:[NSURL URLWithString:BASE_CONTEXT_URL]];
    }

    if (!reqMapping) {
        reqMapping = [RKObjectMapping requestMapping];
    }
}

POST方式：

// Configure a request mapping for our Article class. We want to send back title, body, and publicationDate
RKObjectMapping* deviceRequestMapping = [RKObjectMapping mappingForClass:[DeviceDTO class]];
[deviceRequestMapping addAttributeMappingsFromArray:@[ @"model", @"name", @"systemName", @"systemVersion", @"devToken" ]];

RKObjectMapping* msRequestMapping = [RKObjectMapping mappingForClass:[MemberShipDTO class]];
[msRequestMapping addAttributeMappingsFromArray:@[ @"validSince", @"validTill" ]];

RKObjectMapping* countryRequestMapping = [RKObjectMapping mappingForClass:[CountryDTO class]];
[countryRequestMapping addAttributeMappingsFromArray:@[ @"idNumberDTO", @"iso2DTO", @"short_nameDTO", @"calling_codeDTO" ]];

RKObjectMapping* userRequestMapping = [RKObjectMapping requestMapping];
[userRequestMapping addAttributeMappingsFromArray:@[ @"displayName", @"phoneNumber", @"status", @"userID" ]];

[userRequestMapping addPropertyMapping:[RKRelationshipMapping relationshipMappingFromKeyPath:nil toKeyPath:@"device" withMapping:deviceRequestMapping]];
[userRequestMapping addPropertyMapping:[RKRelationshipMapping relationshipMappingFromKeyPath:nil toKeyPath:@"memberShip" withMapping:msRequestMapping]];
[userRequestMapping addPropertyMapping:[RKRelationshipMapping relationshipMappingFromKeyPath:nil toKeyPath:@"country" withMapping:countryRequestMapping]];

RKRequestDescriptor *requestDescriptor = [RKRequestDescriptor requestDescriptorWithMapping:userRequestMapping objectClass:[User class] rootKeyPath:@"user"];


//Create Objects
UserDTO *user = [[UserDTO alloc]init];
user.displayName = userDTO.displayName;
user.phoneNumber = userDTO.phoneNumber;
user.status = userDTO.status;
user.userID = userDTO.userID;
user.country = userDTO.country;

DeviceDTO *device = [[DeviceDTO alloc]init];
device.name = devDTO.name;
device.systemName = devDTO.systemName;
device.systemVersion = devDTO.systemVersion;
device.model = devDTO.model;
device.devToken = [[NSUserDefaults standardUserDefaults]objectForKey:PUSHTOKEN_USER_DEFAULTS_KEY];

user.deviceInfo = device;

MemberShipDTO *ms = [[MemberShipDTO alloc]init];
ms.validSince = [NSDate date];
ms.validTill = [[UtilitieHandler new] getDateByAdd:+1 :0 :0 :0];

user.memberShipDetails = ms;

[RKMIMETypeSerialization registerClass:[RKNSJSONSerialization class] forMIMEType:@"application/json"];

[[RKObjectManager sharedManager] setRequestSerializationMIMEType:RKMIMETypeJSON];
[[RKObjectManager sharedManager] setAcceptHeaderWithMIMEType:RKMIMETypeJSON];
[[RKObjectManager sharedManager] addRequestDescriptor:requestDescriptor];
[[RKObjectManager sharedManager] postObject:user path:@"user/integrate" parameters:nil success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult){
    RKLogInfo(@"Load collection of Articles: %@", mappingResult.array);
}failure:^(RKObjectRequestOperation *operation, NSError *error) {
    RKLogError(@"Operation failed with error: %@", error);
}];

所以我尝试了不同的东西，在我使用wireshark捕获请求后，它返回没有内容发送。这意味着映射无法正常工作。我尝试了很多，没有任何帮助。任何建议都会很棒！

此处捕获的数据包：

您的问题可能只是一个拼写错误，但requestDescriptor似乎没有链接到UserDTO类。

Answer 2

您似乎还没有了解Core Data对象。使用Core Data持久化的对象是NSManagedObject的子类，必须以不同方式创建。请仔细阅读以下链接： http://developer.apple.com/library/mac/#documentation/cocoa/conceptual/CoreData/Articles/cdCreateMOs.html

至于当前的问题，你必须改为使用它：

NSEntityDescription *entity = [NSEntityDescription entityForName:@"UserDTO" inManagedObjectContext:[RKManagedObjectStore defaultStore].mainQueueManagedObjectContext];

UserDTO *user = [[NSManagedObject alloc] initWithEntity:entity insertIntoManagedObjectContext:nil];

但是，如果UserDTO是NSObject的子类，则需要更改为NSManagedObject。

我的工作流程是这样的 - 创建Core Data模型并使用mogenerator自动生成NSManagedObject类定义。在此处阅读更多相关信息：http://raptureinvenice.com/getting-started-with-mogenerator/

使用RestKit发送POST不返回JSON内容
