Question

我正在制作健康应用程序。我想在Swift中从@GET @Produces(MediaType.APPLICATION_JSON) @Consumes(MediaType.APPLICATION_FORM_URLENCODED) @Path("/categories") public POSResponse getAllCategories() { String countryCode="1"; return infoService.getAllCategories(countryCode); }获取@Mock InfoService infoService; @InjectMocks private InfoController infoController; private MockMvc mockMvc; @Before public void setUp() { MockitoAnnotations.initMocks(this); mockMvc = MockMvcBuilders.standaloneSetup(infoController).build(); } @Test public void getAllCategoriesTest() throws Exception { POSResponse response=new POSResponse(); Category category=new Category(); category.setCountryCode(1); category.setDescription("Mother Dairy"); response.setResponse(category); when(infoService.getAllCategories("1")).thenReturn(response); mockMvc.perform(get("/categories")) .andExpect(status().isOk()) .andExpect(content().contentType(APPLICATION_JSON_UTF8)) .andExpect(jsonPath("$.id", is(1))) .andExpect(jsonPath("$.description", is("Mother Dairy"))); verify(infoService, times(1)).getAllCategories("1"); verifyNoMoreInteractions(infoService); }。但是，我有一个问题。返回值为0.0英里。

为什么返回值是0英里？

我的代码是这样的。

walkingRunningDistance

Answer 1

如果

，您的代码将返回一个值

您已请求用户许可阅读   来自HealthKit的distanceWalkingRunning

用户已授予您的应用权限。

如果没有，您的代码将返回0.

要请求授权，您可以致电

func requestAuthorization(toShare typesToShare: Set<HKSampleType>?, read typesToRead: Set<HKObjectType>?, completion: @escaping (Bool, Error?) -> Swift.Void)

typesToRead包含

let distanceType =  HKSampleType.quantityType(forIdentifier: HKQuantityTypeIdentifier.distanceWalkingRunning)!

我相信使用HKStatisticsQuery或HKStatisticsCollectionQuery会更有效率。这是一个例子。

guard let type = HKSampleType.quantityType(forIdentifier: .distanceWalkingRunning) else {
    fatalError("Something went wrong retriebing quantity type distanceWalkingRunning")
}
let date =  Date()
let cal = Calendar(identifier: Calendar.Identifier.gregorian)
let newDate = cal.startOfDay(for: date)

let predicate = HKQuery.predicateForSamples(withStart: newDate, end: Date(), options: .strictStartDate)

let query = HKStatisticsQuery(quantityType: type, quantitySamplePredicate: predicate, options: [.cumulativeSum]) { (query, statistics, error) in        
    var value: Double = 0

    if error != nil {
        print("something went wrong")
    } else if let quantity = statistics?.sumQuantity() {
        value = quantity.doubleValue(for: HKUnit.mile())
    }
    DispatchQueue.main.async {
        completion(value)
    }
}
healthStore.execute(query)

Answer 2

healthStore =[HKHealthStore new];
HKQuantityType *stepType = [HKQuantityType quantityTypeForIdentifier:HKQuantityTypeIdentifierStepCount];
HKSampleType *sleepType = [HKSampleType categoryTypeForIdentifier:HKCategoryTypeIdentifierSleepAnalysis];
HKQuantityType *walkType = [HKQuantityType quantityTypeForIdentifier:HKQuantityTypeIdentifierDistanceWalkingRunning];
NSArray *arrayType = @[stepType,sleepType,walkType];

[healthStore requestAuthorizationToShareTypes:[NSSet setWithArray:arrayType]
                                    readTypes:[NSSet setWithArray:arrayType] completion:^(BOOL succeeded, NSError *error) {
                                        if (succeeded) {
                                            NSLog(@"Not working");
                                            NSLog(@"error %@",error);
                                        } else {
                                            NSLog(@"Working!");
                                            NSLog(@"error %@",error);
                                        }
                                        [self getStepCount];
                                    }];

以上获取访问权限的方法和以下获取计数的方法

-(void)getStepCount{
     NSInteger limit = 0;
     NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
    [dateFormatter setDateFormat:@"yyyy-MM-dd hh:mm:ss"];
    NSDate *startDate = [NSDate  dateWithTimeIntervalSince1970:1372418789];
    // Divided by 1000 (i.e. removed three trailing zeros) ^^^^^^^^
    NSString *formattedDateString = [dateFormatter stringFromDate:startDate];
   // Fri, 28 Jun 2013 11:26:29 GMT
   NSLog(@"start Date: %@", formattedDateString);
   NSDateFormatter *dateFormatter1=[[NSDateFormatter alloc] init];
   [dateFormatter1 setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
   NSLog(@"%@",[dateFormatter1 stringFromDate:[NSDate date]]);
   NSString *dateString =[dateFormatter1 stringFromDate:[NSDate date]];
  NSDate *endDate = [dateFormatter1 dateFromString:dateString];


 NSPredicate *predicate = [HKQuery predicateForSamplesWithStartDate:startDate endDate:endDate options:HKQueryOptionStrictEndDate];

HKSampleQuery *query = [[HKSampleQuery alloc] initWithSampleType:[HKObjectType quantityTypeForIdentifier:HKQuantityTypeIdentifierDistanceWalkingRunning]
                        predicate: predicate
                        limit: limit
                        sortDescriptors: nil
                        resultsHandler:^(HKSampleQuery *query, NSArray* results, NSError *error){
                            dispatch_async(dispatch_get_main_queue(), ^{
                                // sends the data using HTTP
                                int dailyAVG = 0;
                                NSLog(@"result : %@",results);
                                for(HKQuantitySample *samples in results)
                                {
                                    NSLog(@"dailyAVG : %@",samples);
                                }
                                NSLog(@"dailyAVG : %d",dailyAVG);

                                NSLog(@"%@",@"Done");
                            });
                        }];
[healthStore executeQuery:query];

}

Answer 3

对于Swift 4.1

在项目功能中启用HealthKit并将必要的“隐私-Health Share使用说明”键添加到info.plist文件中...

通过将其添加到ViewController.swift（实际上是在viewDidLoad（）函数中）来确保您正在请求用户的批准。

1535320256

然后创建getSteps（）函数。

    let store = HKHealthStore()

    let stepType = HKQuantityType.quantityType(forIdentifier: .stepCount)!
    let woType = HKObjectType.workoutType()

    store.requestAuthorization(toShare: [], read: [stepType, woType], completion: { (isSuccess, error) in
        if isSuccess {
            print("Working")
            self.getSteps()
        } else {
            print("Not working")
        }
    })
