JSONModel无效JSON数据

Question

我把这个Json从ASP.MVCAPI中拿出来，我有InvModel和LotModel

但当我打电话的时候

_InvFeed = [[InvModel alloc] initFromURLWithString:@"http://192.168.1.206/service/api/dto/inventory/1?p=Red%20Globe"
                                        completion:^(JSONModel *model, JSONModelError *err) 
        {
            NSLog(@"Inventory: %@", _InvFeed );
            NSLog(@"Error: %@",err);
        }];

我找不出这个错误：

Error: Error Domain=JSONModelErrorDomain Code=1 “无效的JSON数据:试图使用initWithDictionary:error:但字典参数不是‘NSDictionary’初始化JSONModel对象”。 UserInfo=0x109075ff0 {NSLocalizedDescription=Invalid JSON数据:尝试使用initWithDictionary:error:初始化JSONModel对象:但是字典参数不是‘NSDicary.kJSONModelKeyPath=LotDTO}

​

下面是JSONModels for: LotDTO

#import "JSONModel.h"

@interface InvLotModel : JSONModel
@property (assign, nonatomic) int lotid;
@property (strong, nonatomic) NSDate* expdate;
@property (strong, nonatomic) NSString* lotserial;
@property (strong, nonatomic) NSDate* lastupddate;
@property (strong, nonatomic) NSString<Optional>* providerlotserial;
@property (assign, nonatomic) NSDecimal* qtyoriginal;
@property (assign, nonatomic) NSDecimal* qtyallocated;
@property (assign, nonatomic) NSDecimal* qtyavailable;
@property (assign, nonatomic) NSDecimal* qtyonhand;
@property (strong, nonatomic) NSDate* receiptdate;
@property (strong, nonatomic) NSString* linecomment;
@property (assign, nonatomic) NSDecimal* unitcost;
@property (strong, nonatomic) NSString* warehouse;
@end

在这里，库存模型

#import "JSONModel.h"
#import "InvLotModel.h"
@protocol InvModel @end
@interface InvModel : JSONModel
@property (assign, nonatomic) int id;
@property (strong, nonatomic) NSString* itemid;
@property (strong, nonatomic) NSString* description;
@property (strong, nonatomic) NSDate* createdate;
@property (strong, nonatomic) NSString* createuser;
@property (assign, nonatomic) float lastcost;
@property (assign, nonatomic) BOOL monitorlevel;
@property (assign, nonatomic) int minlevel;
@property (assign, nonatomic) int maxlevel;
@property (strong, nonatomic) NSString* gtin;
@property (assign, nonatomic) float weight;
@property (strong, nonatomic) NSString* uom;
@property (strong, nonatomic) NSString* sizes;
@property (strong, nonatomic) NSString* variety;
@property (strong, nonatomic) NSString <Optional>* bag;
@property (strong, nonatomic) NSString* style;
@property (strong, nonatomic) NSString* box;
@property (strong, nonatomic) NSString* label;
@property (strong, nonatomic) NSString* commodity;

@property (strong, nonatomic) InvLotModel* LotDTO;
@end

Answer 1

确保将任何扩展属性标记为Ignore。我面临着这样一个问题，试图模仿这个模型。

Answer 2

请把这个换一下

@property (strong, nonatomic) InvLotModel* LotDTO;

有了这个

@property (strong, nonatomic) NSArray<InvLotModel,ConvertOnDemand>* LotDTO;

正如JSONModel的官员建议的那样，在他们的教程中使用ConvertOnDemand将NSArray转换为JSONModelArray，以避免在实现过程中出现错误。
