無法使用RestKit發佈到服務器

Question

我一直在嘗試這種方式已經有一段時間了，但我無法成功發佈到我的服務器。我已閱讀this,github object mapping overview for the Restkit和Gist restKit tutorial。

我的問題

我嘗試後的登錄信息（暱稱，硬件ID，手機型號），並從我的服務器的AccountID。但我正在逐漸從控制檯這樣的響應：

GuessTheImage[6832:70b] *** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<AccountsClass 0x8c5cba0> valueForUndefinedKey:]: this class is not key value coding-compliant for the key AccountInfo.' 

我覺得是這個問題

我相信我搞亂了我的映射部分之前正確的數據存儲方式。但我不確定究竟在哪裏。

，我想後應該是這樣的

{ 
    "DeviceType": "sample string 1", 
    "HardwareId": "sample string 2", 
    "NickName": "sample string 3", 
    "AccountId": 4 
} 

我創建的變量在AccountClass映射程序的概述JSON。從loginviewcontroller，我得到設備類型，hardwareId和暱稱後，用戶單擊登錄按鈕並將這些變量分配給AccountClass中的變量，如果以後映射POST。 AccountClass.h

#import <Foundation/Foundation.h> 

@interface AccountsClass : NSObject 

@property (nonatomic, strong,retain)NSString *DeviceType; 
@property (nonatomic,strong)NSNumber *AccountId; 
@property (nonatomic,strong) NSString *NickName; 
@property (nonatomic,strong) NSNumber *HardwareId; 

@end 

LoginViewController.h

#import <UIKit/UIKit.h> 

@interface LoginViewController : UIViewController<UITextFieldDelegate> 
@property (strong, nonatomic) IBOutlet UITextField *usernameTextField; 
@property (strong, nonatomic) IBOutlet UIButton *submitButton; 
@property (nonatomic,readonly) NSUUID *identifierForVendor; 
@property(nonatomic, readonly, retain) NSString *model; 
@property (nonatomic,readonly,retain)NSString *StoreIdentifierForVendor; 
@property (nonatomic,readonly,retain)NSString *StoreTheModel; 
- (IBAction)submit:(id)sender; 
@property (nonatomic,strong)NSString *nickname; 
@end

    RKResponseDescriptor *AccountDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:responseMapping method:RKRequestMethodAny pathPattern:nil keyPath:nil statusCodes:statusCodes]; 


    RKObjectMapping *requestMapping = [RKObjectMapping requestMapping]; // objectClass == NSMutableDictionary 
    [requestMapping addAttributeMappingsFromArray:@[@"AccountInfo.NickName", @"AccountInfo.HardwareId", @"AccountInfo.DeviceType",@"AccountInfo.AccountId"]]; 
    // For any object of class Article, serialize into an NSMutableDictionary using the given mapping and nest 
    // under the 'article' key path 
    RKRequestDescriptor *requestDescriptor = [RKRequestDescriptor requestDescriptorWithMapping:requestMapping objectClass:[AccountInfo class] rootKeyPath:nil method:RKRequestMethodAny]; 
    RKObjectManager *manager = [RKObjectManager managerWithBaseURL:[NSURL URLWithString:@"https://picquiz.azurewebsites.net"]]; 
           [manager addRequestDescriptor:requestDescriptor]; 
           [manager addResponseDescriptor:AccountDescriptor]; 
           // POST to create 
           [manager postObject:AccountInfo path:@"/Accounts" parameters:nil success:nil failure:nil];

我會感謝你的幫助。

Answer 1

你的問題似乎是：

[requestMapping addAttributeMappingsFromArray:@[@"AccountInfo.NickName", @"AccountInfo.HardwareId", @"AccountInfo.DeviceType",@"AccountInfo.AccountId"]]; 

因爲你試圖POST數據沒有嵌套這樣的數據。它看起來應該是：

[requestMapping addAttributeMappingsFromArray:@[@"NickName", @"HardwareId", @"DeviceType",@"AccountId"]];
