RestKit映射錯誤的對象

Question

我正在使用RestKit，這是我如何對其進行初始化以及添加路由和描述符的方法：

 - (void)initRestClient
 {
     NSURL *baseURL = [NSURL URLWithString:kSomeBaseURL];
     self.manager = [RKObjectManager managerWithBaseURL:baseURL];
     [self.manager setRequestSerializationMIMEType:RKMIMETypeJSON];
     [self.manager setAcceptHeaderWithMIMEType:RKMIMETypeJSON];
     [self.manager addResponseDescriptorsFromArray:[RKObjectManager sharedManager].responseDescriptors];
     [self.manager addRequestDescriptorsFromArray:[RKObjectManager sharedManager].requestDescriptors];
     [self.manager.HTTPClient.operationQueue setMaxConcurrentOperationCount:5];
     [RKObjectManager setSharedManager:self.manager];

     //    AFHTTPClient *client = [RKObjectManager sharedManager].HTTPClient;

     [self initRoutes];
     [self initMappingObjectsAndDiscriptors];
 }

 - (void)initRoutes
 {    
     RKRoute *bannersRoute = [RKRoute routeWithClass:[RKBanner class] pathPattern:@"Banners?categoryID=:categoryID" method:RKRequestMethodGET];
     bannersRoute.shouldEscapePath = YES;
     [self.manager.router.routeSet addRoute:bannersRoute];

     RKRoute *branchesRoute = [RKRoute routeWithClass:[RKBranches class] pathPattern:@"Branches?city=:city&type=:type" method:RKRequestMethodGET];
     branchesRoute.shouldEscapePath = YES;
     [self.manager.router.routeSet addRoute:branchesRoute];

     RKRoute *shortTokenRoute = [RKRoute routeWithClass:[RKShortToken class] pathPattern:@"users/login/quick/shortToken?phone=:phone&extraCode=:extraCode" method:RKRequestMethodGET];
     shortTokenRoute.shouldEscapePath = YES;
     [self.manager.router.routeSet addRoute:shortTokenRoute];

     RKRoute *longTokenRoute = [RKRoute routeWithClass:[RKLongToken class] pathPattern:@"users/login/quick/userDetails?shortToken=:shortToken" method:RKRequestMethodGET];
     longTokenRoute.shouldEscapePath = YES;
     [self.manager.router.routeSet addRoute:longTokenRoute];
 }

- (void)initMappingObjectsAndDiscriptors
{
    RKObjectMapping *bannerMapping = [RKObjectMapping mappingForClass:[RKBanner class]];
    [bannerMapping addAttributeMappingsFromDictionary:[RKBanner getAttributes]];
    RKResponseDescriptor *bannerDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:bannerMapping method:RKRequestMethodAny pathPattern:nil keyPath:@"Banners" statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];

    RKObjectMapping *branchesMapping = [RKObjectMapping mappingForClass:[RKBranches class]];
    [branchesMapping addAttributeMappingsFromDictionary:[RKBranches getAttributes]];
    RKResponseDescriptor *branchesDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:branchesMapping method:RKRequestMethodGET pathPattern:nil keyPath:@"Branches" statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];

    RKObjectMapping *shortTokenMapping = [RKObjectMapping mappingForClass:[RKShortToken class]];
    [shortTokenMapping addAttributeMappingsFromDictionary:[RKShortToken getAttributes]];
    RKResponseDescriptor *shortTokenDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:shortTokenMapping method:RKRequestMethodGET pathPattern:nil keyPath:nil statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];

    RKObjectMapping *longTokenMapping = [RKObjectMapping mappingForClass:[RKLongToken class]];
    [longTokenMapping addAttributeMappingsFromDictionary:[RKLongToken getAttributes]];
    //    longTokenMapping.setDefaultValueForMissingAttributes = YES;
    //    longTokenMapping.setNilForMissingRelationships = YES;
    RKResponseDescriptor *longTokenDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:longTokenMapping method:RKRequestMethodGET pathPattern:nil keyPath:nil statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];

   [self.manager addResponseDescriptorsFromArray:@[bannerDescriptor, branchesDescriptor, shortTokenDescriptor, longTokenDescriptor]];

}

這是每個類的構建方式：

@interface RKBanner : NSObject
@property (strong, nonatomic) NSNumber *idNum;
@property (strong, nonatomic) NSString *name;
@property (strong, nonatomic) NSString *addressURL;
@property (strong, nonatomic) NSString *bannerPosition;

@end

@implementation RKBanner

{
    return [NSDictionary dictionaryWithObjects:@[@"idNum", @"name", @"addressURL", @"bannerPosition", @"imageALT", @"imageHeight",
                                                 @"imageURL", @"imageWidth", @"subtitle", @"targetURL", @"textURL", @"title"]
                                       forKeys:@[@"ID", @"Name", @"AddressURL", @"BannerPosition", @"ImageALT", @"ImageHeight",

}
@end

@interface RKBranches : NSObject
@property (strong, nonatomic) NSNumber *idNum;
@property (strong, nonatomic) NSString *branchTitle;
@property (strong, nonatomic) NSString *address;
@property (strong, nonatomic) NSNumber *branchType;
@property (strong, nonatomic) NSString *city;
@property (strong, nonatomic) NSString *fax;
@property (assign, nonatomic) BOOL isCanOrder;
@property (assign, nonatomic) BOOL isMe;
@property (strong, nonatomic) NSString *openHours;
@property (strong, nonatomic) NSString *orderCode;
@property (strong, nonatomic) NSString *phone;
@property (strong, nonatomic) NSString *remarks;

@end

@implementation RKBranches
+ (NSDictionary*)getAttributes
{
    return [NSDictionary dictionaryWithObjects:@[@"idNum", @"branchTitle", @"address", @"branchType", @"city", @"fax",
                                                 @"isCanOrder", @"isMe", @"openHours", @"orderCode", @"phone", @"remarks"]
                                       forKeys:@[@"ID", @"Name", @"Address", @"BranchType", @"City", @"Fax",
                                                 @"IsCanOrder", @"IsMe", @"OpenHours", @"OrderCode", @"Phone", @"Remarks"]];
}
@end

@interface RKShortToken : NSObject
@property (strong, nonatomic) NSString *responseError;
@property (strong, nonatomic) NSString *shortToken;
+ (NSDictionary*)getAttributes;
@end

@implementation RKShortToken
+ (NSDictionary*)getAttributes
{
    return [NSDictionary dictionaryWithObjects:@[@"responseError", @"shortToken"]
                                       forKeys:@[@"responseError", @"shortToken"]];
}
@end

@interface RKLongToken : NSObject
@property (strong, nonatomic) NSString *responseError;
@property (strong, nonatomic) NSString *responseMessage;
@property (strong, nonatomic) NSString *responseHttpCode;
@property (strong, nonatomic) NSString *responseUserMessage;
@property (strong, nonatomic) NSString *abroadInd;
@property (strong, nonatomic) NSString *accountType;
@property (strong, nonatomic) NSString *customerID;
@property (strong, nonatomic) NSString *longToken;
+ (NSDictionary*)getAttributes;
@end

@implementation RKLongToken
+ (NSDictionary*)getAttributes
{
    return [NSDictionary dictionaryWithObjects:@[@"responseError", @"responseMessage", @"responseHttpCode", @"responseUserMessage",
                                                 @"abroadInd", @"accountType", @"customerID", @"longToken"]
                                       forKeys:@[@"responseError", @"responseError.DeveloperMessage", @"responseError.HttpCode", @"responseError.UserMessage",
                                                 @"abroadInd", @"accountType", @"customerId", @"longToken"]];
}
@end

比起我嘗試調用RKShortToken時，我得到了一個很好的響應，但是得到的對象是RKLongToken：

- (void)quickLoginWithTelephone:(NSString*)telephone extraCode:(NSString *)extraCode completionBlock:(quickLoginExtraCodeCompletionBlock)success
{
    NSDictionary *params = @{ @"phone" : telephone, @"extraCode" : extraCode };
    [[RKObjectManager sharedManager] getObjectsAtPath:@"users/login/quick/shortToken?"
                                           parameters:params
                                              success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
                                                  NSLog(@"%@", operation.HTTPRequestOperation.responseString);
                                                  NSLog(@"%@", mappingResult.array);
                                                  success(YES);
                                              } failure:^(RKObjectRequestOperation *operation, NSError *error) {
                                                  NSLog(@"Error occurred.");
                                              }];
}

這是日志：

這里似乎是什么問題？

更新：

我已經添加pathPattern的描述符@Wain告訴我，但現在我發現了一個錯誤。 看起來像這樣：

"No mappable object representations were found at the key paths searched."

NSLocalizedFailureReason=The mapping operation was unable to find any nested object representations at the key paths searched: Banners, Branches, BranchTypes, Cities, MenuList
The representation inputted to the mapper was found to contain nested object representations at the following key paths: responseError, shortToken
This likely indicates that you have misconfigured the key paths for your mappings., NSLocalizedDescription=No mappable object representations were found at the key paths searched., keyPath=null}`

Answer 1

您所有的響應描述符都具有pathPattern:nil ，因此RestKit無法過濾，將應用所有它們並查看會發生什么。 因此，對於所有JSON，您將獲得多個對象，這些對象僅包含每個映射中與JSON匹配的部分。

要解決此問題，請添加路徑模式，以允許RestKit確定哪個響應描述符與您的每個請求匹配。

Answer 2

正確的方法是首先初始化RestKit客戶端：

NSURL *baseURL = [NSURL URLWithString:kServiceBaseURL];
self.manager = [RKObjectManager managerWithBaseURL:baseURL];
[self.manager setRequestSerializationMIMEType:RKMIMETypeJSON];
[self.manager setAcceptHeaderWithMIMEType:RKMIMETypeJSON];
[self.manager addResponseDescriptorsFromArray:[RKObjectManager sharedManager].responseDescriptors];
[self.manager addRequestDescriptorsFromArray:[RKObjectManager sharedManager].requestDescriptors];
[self.manager.HTTPClient.operationQueue setMaxConcurrentOperationCount:5];
[RKObjectManager setSharedManager:self.manager];

比初始化所需的路由：

RKRoute *shortTokenRoute = [RKRoute routeWithClass:[RKShortToken class] pathPattern:@"users/login/quick/shortToken" method:RKRequestMethodGET];
shortTokenRoute.shouldEscapePath = YES;
[self.manager.router.routeSet addRoute:shortTokenRoute];

比創建一個reponseDescriptor：

RKObjectMapping *shortTokenMapping = [RKObjectMapping mappingForClass:[RKShortToken class]];
[shortTokenMapping addAttributeMappingsFromDictionary:@{ @"responseError" : @"responseError", @"shortToken" : @"shortToken" }];
RKResponseDescriptor *shortTokenDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:shortTokenMapping
                                                                                          method:RKRequestMethodAny
                                                                                     pathPattern:@"users/login/quick/shortToken"
                                                                                         keyPath:nil
                                                                                     statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];
[[RKObjectManager sharedManager] addResponseDescriptor:shortTokenDescriptor];

比要求：

NSDictionary *params = @{ @"phone" : telephone, @"extraCode" : extraCode };
[[RKObjectManager sharedManager] getObject:[[RKShortToken alloc] init]
                                      path:@"users/login/quick/shortToken"
                                parameters:params
                                   success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
                                       NSLog(@"%@", operation.HTTPRequestOperation.responseString);
                                   } failure:^(RKObjectRequestOperation *operation, NSError *error) {
                                       NSLog(@"%@", error.localizedDescription);
                                   }];
