Can't get RestKit 0.2 to POST parameters

所以我正在尝试使用 [RKObjectManager postObject:path:parameters:success:failure:]，但是在使用我的登录 POST 请求时遇到了一些麻烦。出于某种原因，我不断收到来自服务器的回复，说电子邮件和密码的参数是必需的，即使我将以下字典传递给参数：

NSDictionary *params = @{@"email": @"[email protected], @"password": @"test123!"};

当我注销 RKObjectRequestOperation 时，它不会在请求中显示任何参数。我必须在请求中传递一个对象吗？如果是这样，我会传入什么对象？

(以前我只是使用 and AFJSONRequestOperation，但我想更新应用程序以使用 RestKit 并利用它提供的简单对象映射)。

任何帮助将不胜感激。

编辑更多代码：

我有一个名为 UserAuthService 的 RKObjectManager 子类，使用 RKMIMETYPEJSON 作为 requestSerializationMIMEType，具有以下请求描述符设置：

1
2
3
4
5
6
7

// User
RKResponseDescriptor *userResponseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:[UserAuthMappingProvider userMapping]
method:RKRequestMethodPOST
pathPattern:@"user/login"
keyPath:@"response.users"
statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];
[self addResponseDescriptor:userResponseDescriptor];

我实际请求的方法是：

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15

- (void)logUserInWithEmail:(NSString *)email andPassword:(NSString *)password success:(void (^)(UserObject *))success failure:(void (^)(RKObjectRequestOperation *, NSError *))failure
{
// Request Params
NSDictionary *params = @{@"email": email, @"password": password};
NSLog(@"Params: %@", params);

[self postObject:nil path:@"user/login" parameters:params
success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult){
if (success)
{
NSArray *userArray = [mappingResult array];
success([userArray firstObject]);
}

}
failure:^(RKObjectRequestOperation *operation, NSError *error){
NSLog(@"Error: %@", error);

if (failure)
{
failure(operation, error);
}
}];
}

UserAuthMappingProvider 中的 userMapping 方法如下所示：

+ (RKEntityMapping *)userMapping
{
AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];

RKEntityMapping *userMapping = [RKEntityMapping mappingForEntityForName:@"User" inManagedObjectStore:appDelegate.managedObjectStore];
userMapping.identificationAttributes = @[ @"uuid" ];

[userMapping addAttributeMappingsFromDictionary:@{@"email": @"email",
@"first_name": @"firstName",
@"last_name": @"lastName",
@"is_logged_in": @"isLoggedIn",
@"site_id": @"siteID",
@"user_name": @"username",
@"uuid": @"uuid"}];
return userMapping;
}

和 UserObject(在 .m 中每个都设置为 @dynamic)：

1
2
3
4
5

10
11

@interface UserObject : NSManagedObject

@property (strong, nonatomic) NSString *email;
@property (strong, nonatomic) NSString *firstName;
@property (strong, nonatomic) NSString *lastName;
@property (assign, nonatomic) BOOL isLoggedIn;
@property (strong, nonatomic) NSNumber *siteID;
@property (strong, nonatomic) NSString *username;
@property (strong, nonatomic) NSString *uuid;

@end

我返回的错误是：

Error Domain=org.restkit.RestKit.ErrorDomain Code=-1011"Expected status code in (200-299), got 400" UserInfo=0x8eadbf0 {NSLocalizedRecoverySuggestion={"required_parameters":{"email":"string","password":"string"},"status":"failed","message":"Insufficient information passed. see 'required_parameters'"}

基本上我的目标是获取用户/登录调用的成功响应并将其映射到 UserObject。
