如何解决RestKit JSON序列化问题

我试图用为POST JSON对象（有时数组只包含一个对象）一个REST服务的阵列RestKit 0.2如何解决RestKit JSON序列化问题

我想被发送到服务应该是这个样子的阵列与一个对象：

{[ 
     { 
     "Latitude":0, 
     "Location":"Nowhere, FL", 
     "Id":25699, 
     "Version":0, 
     "Name":"TEST Customer Airport 2 created by tstUser", 
     "TimeZone":":America\/New York", 
     "Longitude":0, 
     "Code":"XXXX987", 
     "IsUserDefinedAirportCode":true 
     } 
]}

这里是RestKit根据跟踪输出发送在request.body：

{ 
    "\/AirportCode\/UpsertCustomerAirportCodes":[ 
     { 
     "Latitude":0, 
     "Location":"Nowhere, FL", 
     "Id":25699, 
     "Version":0, 
     "Name":"TEST Customer Airport 2 created by tstUser", 
     "TimeZone":":America\/New York", 
     "Longitude":0, 
     "Code":"XXXX987", 
     "IsUserDefinedAirportCode":true 
     } 
    ] 
}

json的第一个元素是我打电话的服务的资源/操作路径。为什么RestKit把它放在Json中？

详细...

要送这个，我有一个ApiAirportCode模型对象：

#import <Foundation/Foundation.h> 

@interface ApiAirportCode : NSObject <NSCoding> 

@property (nonatomic, copy) NSString *Code; 
@property (nonatomic, copy) NSNumber *Id; 
@property (nonatomic, copy) NSNumber *Latitude; 
@property (nonatomic, copy) NSString *Location; 
@property (nonatomic, copy) NSNumber *Longitude; 
@property (nonatomic, copy) NSString *Name; 
@property (nonatomic, copy) NSString *TimeZone; 
@property (nonatomic, assign) bool IsUserDefinedAirportCode; 

@end

这里是映射：

RKObjectMapping* airportCodePostMap = [RKObjectMapping mappingForClass:[ApiAirportCode class]]; 
[airportCodePostMap addAttributeMappingsFromArray:@[@"Code", @"Id", @"Latitude", @"Location", @"Longitude", @"Name", @"TimeZone", @"IsUserDefinedAirportCode"]]; 
RKRequestDescriptor* airportCodePostReqDescriptor = [RKRequestDescriptor requestDescriptorWithMapping:[airportCodePostMap inverseMapping] objectClass:[ApiAirportCode class] rootKeyPath:@"/AirportCode/UpsertCustomerAirportCodes" method:RKRequestMethodPOST]; 
[_ObjectManager addRequestDescriptor:airportCodePostReqDescriptor];

这里是调用服务：

- (void) saveCustomAirportCodesToServer:(NSArray*) customAirports 
{ 
    _ObjectManager.requestSerializationMIMEType=RKMIMETypeJSON; 
    [_ObjectManager postObject:customAirports path:@"/AirportCode/UpsertCustomerAirportCodes" parameters:NULL success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) { 

     // Do something 


    } failure:^(RKObjectRequestOperation *operation, NSError *error) { 

     ApiPayload* errorPld = [[error userInfo] objectForKey:RKObjectMapperErrorObjectsKey][0]; 

    }]; 

    // Do something... 
}

这里是从RestKit输出的跟踪：

我想通了。 ..

我的问题是与rootKeyPath参数RKRequestDescriptor requestDescriptorWithMapping。这应该是零。

我经过在资源/动作名称，因为我认为RestKit使用该知道何时使用这种请求描述符（就像为与withPathPattern参数映射响应）。不知道为什么有ins't需要传递的东西来表示withPathPattern。

所以这行代码：

RKRequestDescriptor* airportCodePostReqDescriptor = [RKRequestDescriptor requestDescriptorWithMapping:[airportCodePostMap inverseMapping] objectClass:[ApiAirportCode class] rootKeyPath:@"/AirportCode/UpsertCustomerAirportCodes" method:RKRequestMethodPOST];

应该

RKRequestDescriptor* airportCodePostReqDescriptor = [RKRequestDescriptor requestDescriptorWithMapping:[airportCodePostMap inverseMapping] objectClass:[ApiAirportCode class] rootKeyPath:nil method:RKRequestMethodPOST];
