RestKit 0.20 Post Array Json 问题 [英] RestKit 0.20 Post Array Json issues

问题描述

这是我需要发布到服务的 json.

This is the json that I need to post to services.

{
"deviceToken":"asdfasdfasdf",
"alarm": [
{
    "start" "8:30",
    "end": "9:30",
    "line": "156",
    "code": "xxxafsdfasdf", 
    "station": "asdfa",
    "stationLeft": 5,
    "available": true,
    "times": 2
}]
}

响应数据只是在警报中多了一个字段id":

The response data just have one more field "id" in alarm:

    {
        "deviceToken":"asdfasdfasdf",
        "alarm": [
        {
           "id":1,
           "start" "8:30",
           "end": "9:30",
           "line": "156",
           "code": "xxxafsdfasdf", 
           "station": "asdfa",
           "stationLeft": 5,
           "available": true,
           "times": 2
        }]
     }

然后我定义了两个对象:设备警报对象:

Then I define two objects: DeviceAlarm Object:

@interface DeviceAlarm : NSObject

@property(nonatomic, strong) NSMutableArray *alarm;

@property(nonatomic, copy) NSString *deviceToken;

@end

报警对象:

@interface Alarm : NSObject

@property(nonatomic, copy) NSNumber *id;

@property(nonatomic, copy) NSString *start;

@property(nonatomic, copy) NSString *end;

@property(nonatomic, copy) NSString *code;

@property(nonatomic, copy) NSString *line;

@property(nonatomic, copy) NSString *station;

@property(nonatomic, copy) NSNumber *stationLeft;

@property(nonatomic) BOOL available;

@property(nonatomic, copy) NSNumber *times;

@end

这是我要发布的代码.

DeviceAlarm* devicealarm = [[DeviceAlarm alloc] init];

Alarm* alarm = [[Alarm alloc] init];
alarm.start = @"8:00";
alarm.end = @"9:30";
alarm.line = @"156";
alarm.code = @"fasdfasdf";
alarm.station = @"asdfas";
alarm.stationLeft = @1000;
alarm.available = true;
alarm.times = @1;

devicealarm.alarm = [NSArray arrayWithObjects:alarm , nil];
devicealarm.deviceToken = @"adsfasdfasdf";

RKObjectMapping *alarmMapping = [RKObjectMapping requestMapping];

[alarmMapping addAttributeMappingsFromArray:@[@"start",@"end",@"code",@"station", @"stationLeft",@"available",@"times",@"line"]];

RKObjectMapping *deviceMapping = [RKObjectMapping requestMapping];

RKRelationshipMapping *alarmRelationship = [RKRelationshipMapping
                                           relationshipMappingFromKeyPath:@"alarm"
                                           toKeyPath:@"alarm"
                                           withMapping:alarmMapping];


[deviceMapping addAttributeMappingsFromArray:@[@"deviceToken"]];

[deviceMapping addPropertyMapping:alarmRelationship];

NSString* path = @"/api/alarm/asdfasdf";
RKRequestDescriptor *requestDescriptor = [RKRequestDescriptor requestDescriptorWithMapping:deviceMapping
                                                                               objectClass:[DeviceAlarm class]
                                                                               rootKeyPath:nil];

RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:[DeviceAlarm DeviceAlarmResponseMapping]
                                                                                   pathPattern:nil
                                                                                       keyPath: nil
                                                                                   statusCodes:[NSIndexSet indexSetWithIndex:200]];


RKObjectManager *manager = [RKObjectManager managerWithBaseURL:[NSURL URLWithString:@"http://127.0.0.1:5000/"]];
[manager addRequestDescriptor:requestDescriptor];
[manager addResponseDescriptor:responseDescriptor];

[manager postObject:devicealarm path:path parameters:nil
                                    success:^(RKObjectRequestOperation *operation, RKMappingResult *result) {
                                        NSLog(@"Loading mapping result: %@", result);

                                    } failure:^(RKObjectRequestOperation *operation, NSError *error) {
                                        RKLogError(@"Operation failed with error: %@", error);
                                    }];

然后查看services中的post数据，发现restkit post了一个错误数组json.警报字典丢失.

Then I check the post data in services, I found restkit post an error array json. alarm dict lost.

    {
        "deviceToken":"asdfasdfasdf",
        "alarm": [
                  "8:30",
                  "9:30",
                  "156",
                  "xxxafsdfasdf", 
                  "asdfa",
                  5,
                  true,
                  2
         ]
     }

请帮帮我~:)

推荐答案

LOL，我已经解决了我的问题，我将 DeviceAlarm 对象中的字段类型从NSMutableArray"更改为NSSet"，然后它就可以工作了.我不知道为什么.希望能帮到我们.

LOL, I have fixed my issues, I changed the field type from "NSMutableArray" to "NSSet" in DeviceAlarm Object, and then it works. I don't know why. Hope it can help us.
