Question

我正在尝试使用RestKit 0.2将一个json对象数组（有时数组只包含一个对象）发送到REST服务

对于包含一个对象的数组，我想要发送到服务的内容应该类似于这样：

{[
      {
         "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根据跟踪输出在request.body中发送的内容：

{
   "\/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的第一个元素是我正在调用的服务的资源/操作路径。为什么RestKit会把它放在Json中？

详细...

要发送此信息，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

以下是映射：

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];

以下是对服务的调用：

- (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...
}

以下是RestKit的跟踪输出：

Answer 1

我明白了......

我的问题是使用rootKeyPath参数到RKRequestDescriptor requestDescriptorWithMapping。这应该是零。

我传递了资源/操作名称，因为我认为RestKit正在使用它知道何时使用此请求描述符（就像使用withPathPattern参数映射响应一样）。不确定为什么不需要传递一些东西来指示withPathPattern。

所以这行代码：

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

应该是

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