搜索和应用过滤条件

所需的授权范围

photoslibrary.readonly 范围允许访问用户媒体库中的所有媒体内容。

若要搜索应用创建的内容并对其应用过滤条件，需要 photoslibrary.readonly.appcreateddata 范围。如需详细了解范围，请参阅授权范围。

可用过滤器

您可以在用户的应用创建的媒体内容库中搜索特定类型的媒体。例如，您可能只想查找特定日期的动物相关内容，或者可能想要排除收据照片。您可以在影集或媒体库列表中应用过滤器，从而排除或添加特定内容。根据媒体内容属性，提供以下五种可用的过滤器：

内容类别 (includedContentCategories、excludedContentCategories)
日期和日期范围（dates、ranges）
功能 (featureFilter)
媒体类型 (mediaTypeFilter)
已归档状态 (includeArchivedMedia)

如果已设置 albumId，则不应在 mediaItems.search 请求中使用过滤器。如果在已设置 photosId 时使用过滤条件，系统会返回 INVALID_ARGUMENT 错误 (400)。

结果会按媒体内容创建时间排序。对于使用日期过滤条件的查询，可以修改排序顺序。

新上传的媒体需过一段时间后才能出现在搜索结果中，媒体会立即显示在未经过滤的搜索结果中。

若媒体内容的日期是未来日期，则其不会出现在已过滤的搜索结果中。但会出现在未经过滤的搜索结果以及影集搜索结果中。

应用过滤器

如需应用过滤器，请调用 mediaItems.search 并指定 filter 属性。

REST

以下是 POST 请求：

POST https://photoslibrary.googleapis.com/v1/mediaItems:search
Content-type: application/json
Authorization: Bearer oauth2-token
{
  "pageSize": "100",
  "filters": {
    ...
  }
}

POST 请求会返回以下响应：

{
  "mediaItems": [
    ...
  ],
  "nextPageToken": "token-for-pagination"
}

Java

try {
  // Create a new Filter object
  Filters filters = Filters.newBuilder()
      // .setContentFilter(...)
      // .setDateFilter(...)
      // ...
      .build();

  // Specify the Filter object in the searchMediaItems call
  SearchMediaItemsPagedResponse response = photosLibraryClient.searchMediaItems(filters);
  for (MediaItem item : response.iterateAll()) {
    // ...
  }
} catch (ApiException e) {
  // Handle error
}

PHP

try {
    $filtersBuilder = new FiltersBuilder();
    // $filtersBuilder->addIncludedCategory(...);
    // $filtersBuilder->addDate(...);
    // ...
    // Make a search call with the options set in the filters builder
    $response = $photosLibraryClient->searchMediaItems(
        ['filters' => $filtersBuilder->build()]
    );
    foreach ($response->iterateAllElements() as $element) {
        // ...
    }
} catch (\Google\ApiCore\ApiException $e) {
    // Handle error
}

有关详情，请参阅列出媒体库内容、影集和媒体内容。

内容分类

您需处理所有媒体内容并为其分配标签。您可以添加和排除以下任何类别。

`ANIMALS`	`FASHION`	`LANDMARKS`	`RECEIPTS`	`WEDDINGS`
`ARTS`	`FLOWERS`	`LANDSCAPES`	`SCREENSHOTS`	`WHITEBOARDS`
`BIRTHDAYS`	`FOOD`	`NIGHT`	`SELFIES`
`CITYSCAPES`	`GARDENS`	`PEOPLE`	`SPORT`
`CRAFTS`	`HOLIDAYS`	`PERFORMANCES`	`TRAVEL`
`DOCUMENTS`	`HOUSES`	`PETS`	`UTILITY`

实用助手照片涵盖大量媒体内容。此类别通常包含用户为执行某项任务而捕获的内容，且完成该任务后可能就不再需要这些内容，其中包括文档、收据、屏幕截图、便笺、菜单及其他类似的媒体内容。

这些类别的准确性仅与 Google 相册内的同等标签相同。有时，项的标签可能有误，因此，我们不保证内容类别过滤器的准确性。

添加类别

如果您添加多个类别，则返回结果会包含与任一类别匹配的媒体内容。每个请求最多可包含 10 个类别。以下示例过滤器将返回 LANDSCAPES 或 LANDMARKS 类别的所有内容。

REST

{
  "filters": {
    "contentFilter": {
      "includedContentCategories": [
        "LANDSCAPES",
        "LANDMARKS"
      ]
    }
  }
}

Java

// Create a content filter that includes landmarks and landscapes
ContentFilter contentFilter = ContentFilter.newBuilder()
    .addIncludedContentCategories(ContentCategory.LANDMARKS)
    .addIncludedContentCategories(ContentCategory.LANDSCAPES)
    .build();
// Create a new Filters object
Filters filters = Filters.newBuilder()
    .setContentFilter(contentFilter)
    .build();
// Specify the Filter object in the searchMediaItems call
SearchMediaItemsPagedResponse response = photosLibraryClient.searchMediaItems(filters);

PHP

// Create a content filter that includes landmarks and landscapes
$filtersBuilder = new FiltersBuilder();
$filtersBuilder->addIncludedCategory(ContentCategory::LANDMARKS);
$filtersBuilder->addIncludedCategory(ContentCategory::LANDSCAPES);
// Make a search call with the options set in the filters builder
$response = $photosLibraryClient->searchMediaItems(
    ['filters' => $filtersBuilder->build()]
);

排除类别

返回结果仅显示与任一已排除类别不匹配的媒体内容。与添加的类别类似，每个请求最多可排除 10 个类别。

以下过滤器将返回不属于 PEOPLE 或 SELFIES 类别的所有内容：

REST

{
  "filters": {
    "contentFilter": {
      "excludedContentCategories": [
        "PEOPLE",
        "SELFIES"
      ]
    }
  }
}

Java

// Create a content filter that excludes people and selfies
ContentFilter contentFilter = ContentFilter.newBuilder()
    .addExcludedContentCategories(ContentCategory.PEOPLE)
    .addExcludedContentCategories(ContentCategory.SELFIES)
    .build();
// Create a new Filters object
Filters filters = Filters.newBuilder()
    .setContentFilter(contentFilter)
    .build();
// Specify the Filter object in the searchMediaItems call
SearchMediaItemsPagedResponse response = photosLibraryClient.searchMediaItems(filters);

PHP

// Create a content filter that excludes people and selfies
$filtersBuilder = new FiltersBuilder();
$filtersBuilder->addExcludedCategory(ContentCategory::PEOPLE);
$filtersBuilder->addExcludedCategory(ContentCategory::SELFIES);
// Make a search call with the options set in the filters builder
$response = $photosLibraryClient->searchMediaItems(
    ['filters' => $filtersBuilder->build()]
);

添加和排除多个类别

您可以添加一些类别并排除其他类别。以下示例会返回 LANDSCAPES 和 LANDMARKS，但会移除包含 PEOPLE 或 SELFIES 的所有媒体内容：

REST

{
  "filters": {
    "contentFilter": {
      "includedContentCategories": [
        "LANDSCAPES",
        "LANDMARKS"
      ],
      "excludedContentCategories": [
        "PEOPLE",
        "SELFIES"
      ]
    }
  }
}

Java

// Create a content filter that excludes people and selfies and includes landmarks and landscapes
ContentFilter contentFilter = ContentFilter.newBuilder()
    .addIncludedContentCategories(ContentCategory.LANDSCAPES)
    .addIncludedContentCategories(ContentCategory.LANDMARKS)
    .addExcludedContentCategories(ContentCategory.PEOPLE)
    .addExcludedContentCategories(ContentCategory.SELFIES)
    .build();
// Create a new Filters object
Filters filters = Filters.newBuilder()
    .setContentFilter(contentFilter)
    .build();
// Specify the Filters object in the searchMediaItems call
SearchMediaItemsPagedResponse response = photosLibraryClient.searchMediaItems(filters);

PHP

// Create a content filter that excludes people and selfies and includes landmarks and landscapes
$filtersBuilder = new FiltersBuilder();
$filtersBuilder->addIncludedCategory(ContentCategory::LANDMARKS);
$filtersBuilder->addIncludedCategory(ContentCategory::LANDSCAPES);
$filtersBuilder->addExcludedCategory(ContentCategory::PEOPLE);
$filtersBuilder->addExcludedCategory(ContentCategory::SELFIES);
// Make a search call with the options set in the filters builder
$response = $photosLibraryClient->searchMediaItems(
    ['filters' => $filtersBuilder->build()]
);

日期和日期范围

日期过滤器可将返回结果的日期限制为指定的日期范围。有两种方法可指定日期过滤器：指定日期或指定日期范围。日期和范围可以一起使用。系统会返回与任意日期或日期范围匹配的媒体内容。（可选）您可以修改结果的排序顺序。

日期

包含年、月和日的日期。以下为可接受的格式：

年
年，月
年，月，日
月，日
月

如果日期的某个部分为空或设为 0，则将其视为通配符。例如，如果设置日和月，而未设置年，则您请求的是任一年该月该日的内容：

REST

{
  "filters": {
    "dateFilter": {
      "dates": [
        {
          "month": 2,
          "day": 15
        }
      ]
    }
  }
}

Java

// Create a new com.google.type.Date object using a builder
// Note that there are different valid combinations as described above
Date dayFebruary15 = Date.newBuilder()
    .setDay(15)
    .setMonth(2)
    .build();
// Create a new dateFilter. You can also set multiple dates here
DateFilter dateFilter = DateFilter.newBuilder()
    .addDates(dayFebruary15)
    .build();
// Create a new Filters object
Filters filters = Filters.newBuilder()
    .setDateFilter(dateFilter)
    .build();
// Specify the Filters object in the searchMediaItems call
SearchMediaItemsPagedResponse response = photosLibraryClient.searchMediaItems(filters);

PHP

// Create a new Google\Type\Date object with a day and a month
// Note that there are different valid combinations as described above
$dateFebruary15 = new Date();
$dateFebruary15->setDay(15);
$dateFebruary15->setMonth(2);
$filtersBuilder = new FiltersBuilder();
// Add the date to the filter. You can also set multiple dates here
$filtersBuilder->addDate($dateFebruary15);
// Make a search call with the options set in the filters builder
$response = $photosLibraryClient->searchMediaItems(
    ['filters' => $filtersBuilder->build()]
);

日期范围

日期范围比日期更加灵活。例如，您可以使用日期范围查看某个月的一组日期。

日期范围包含 startDate 和 endDate，且必须同时设置二者。如日期中所述，日期范围内的每个日期均具有相同的格式限制。这些日期必须具有相同的格式：如果开始日期包含年和月，则结束日期也必须包含年和月。此限制适用于所应用过滤器中的整个日期范围，包括开始日期和结束日期：

REST

{
  "filters": {
    "dateFilter": {
      "ranges": [
        {
          "startDate": {
            "year": 2014,
            "month": 6,
            "day": 12
          },
          "endDate": {
            "year": 2014,
            "month": 7,
            "day": 13
          }
        }
      ]
    }
  }
}

Java

// Create new com.google.type.Date objects for two dates
Date day2014June12 = Date.newBuilder()
    .setDay(12)
    .setMonth(6)
    .setYear(2014)
    .build();
Date day2014July13 = Date.newBuilder()
    .setDay(13)
    .setMonth(7)
    .setYear(2014)
    .build();
// Create a DateRange from these two dates
DateRange dateRange = DateRange.newBuilder()
    .setStartDate(day2014June12)
    .setEndDate(day2014July13)
    .build();
// Create a new dateFilter with the date range. You can also set multiple date ranges here
DateFilter dateFilter = DateFilter.newBuilder()
    .addRanges(dateRange)
    .build();
// Create a new Filters object
Filters filters = Filters.newBuilder()
    .setDateFilter(dateFilter)
    .build();
// Specify the Filters object in the searchMediaItems call
SearchMediaItemsPagedResponse response = photosLibraryClient.searchMediaItems(filters);

PHP

// Create two new Google\Type\Date objects
    $date2014June12 = new Date();
    $date2014June12->setDay(12);
    $date2014June12->setMonth(6);
    $date2014June12->setYear(2014);

    $date2014July13 = new Date();
    $date2014July13->setDay(13);
    $date2014July13->setMonth(7);
    $date2014July13->setYear(2014);

    // Add the two dates as a date range to the filter
    // You can also set multiple date ranges here
    $filtersBuilder = new FiltersBuilder();
    $filtersBuilder->addDateRange($date2014June12, $date2014July13);

    // Make a search call with the options set in the filters builder
    $response = $photosLibraryClient->searchMediaItems(
        ['filters' => $filtersBuilder->build()]
    );

组合日期和日期范围

您可以同时使用多个日期和日期范围，结果中将包含这些日期内的所有内容。单独的日期和日期范围不需要采用相同的格式，但各个范围的开始日期和结束日期需要遵循：

REST

{
  "filters": {
    "dateFilter": {
      "dates": [
        {
          "year": 2013
        },
        {
          "year": 2011,
          "month": 11
        }
      ],
      "ranges": [
        {
          "startDate": {
            "month": 1
          },
          "endDate": {
            "month": 3
          }
        },
        {
          "startDate": {
            "month": 3,
            "day": 24
          },
          "endDate": {
            "month": 5,
            "day": 2
          }
        }
      ]
    }
  }
}

Java

// Create a new com.google.type.Date object for the year 2013
Date day2013 = Date.newBuilder()
    .setYear(2013)
    .build();
// Create a new com.google.type.Date object for November 2011
Date day2011November = Date.newBuilder()
    .setMonth(11)
    .setYear(2011)
    .build();
// Create a date range for January to March
DateRange dateRangeJanuaryToMarch = DateRange.newBuilder()
    .setStartDate(Date.newBuilder().setMonth(1).build())
    .setEndDate(Date.newBuilder().setMonth(3).build())
    .build();
// Create a date range for March 24 to May 2
DateRange dateRangeMarch24toMay2 = DateRange.newBuilder()
    .setStartDate(Date.newBuilder().setMonth(3).setDay(24).build())
    .setEndDate(Date.newBuilder().setMonth(5).setDay(2).build())
    .build();
// Create a new dateFilter with the dates and date ranges
DateFilter dateFilter = DateFilter.newBuilder()
    .addDates(day2013)
    .addDates(day2011November)
    .addRanges(dateRangeJanuaryToMarch)
    .addRanges(dateRangeMarch24toMay2)
    .build();
// Create a new Filters object
Filters filters = Filters.newBuilder()
    .setDateFilter(dateFilter)
    .build();
// Specify the Filter object in the searchMediaItems call
SearchMediaItemsPagedResponse response = photosLibraryClient.searchMediaItems(filters);

PHP

// Create a new Google\Type\Date object for the year 2013
$date2013 = new Date();
$date2013->setYear(2013);

// Create a new Google\Type\Date object for November 2011
$dateNovember2011 = new Date();
$dateNovember2011->setMonth(11);
$dateNovember2011->setYear(2011);

$filtersBuilder = new FiltersBuilder();

// Create a date range for January to March
$filtersBuilder->addDateRange((new Date())->setMonth(1),
    (new Date())->setMonth(3));

// Create a date range for March 24 to May 2
$filtersBuilder->addDateRange((new Date())->setMonth(3)->setDay(24),
    (new Date())->setMonth(5)->setDay(2));

$filtersBuilder->addDate($date2013);
$filtersBuilder->addDate($dateNovember2011);

// Make a search call with the options set in the filters builder
$response = $photosLibraryClient->searchMediaItems(
    ['filters' => $filtersBuilder->build()]
);

媒体内容功能

功能过滤条件将结果限制为具有特定特征的内容，例如已在 Google 相册应用中标记为收藏夹的内容。

在 FeatureFilter 中添加 FAVORITES 项功能，以便仅返回由用户标记为收藏的媒体内容：

REST

{
  "filters" : {
    "featureFilter": {
      "includedFeatures": [
        "FAVORITES"
      ]
    }
  }
}

Java

// Create a new FeatureFilter for favorite media items
FeatureFilter featureFilter = FeatureFilter.newBuilder()
    .addIncludedFeatures(Feature.FAVORITES)
    .build();
// Create a new Filters object
Filters filters = Filters.newBuilder()
    .setFeatureFilter(featureFilter)
    .build();
// Specify the Filters object in the searchMediaItems call
SearchMediaItemsPagedResponse response = photosLibraryClient.searchMediaItems(filters);

PHP

// Create a new FeatureFilter for favorite media items
$filtersBuilder = new FiltersBuilder();
$filtersBuilder->addIncludedFeature(Feature::FAVORITES);

// Make a search call with the options set in the filters builder
$response = $photosLibraryClient->searchMediaItems(
    ['filters' => $filtersBuilder->build()]
);

媒体类型

您可以将结果的媒体类型限制为照片或视频。

照片

PHOTO 可以为以下任一图片格式：

BMP	JPG
GIF	PNG
HEIC	TIFF
ICO	WEBP

它还包括特殊照片类型，例如 iOS Live Photo、动态照片、全景图片、Photo Sphere 照片和 VR 照片。

视频

VIDEO 可以是多种视频格式：

3GP	综合格斗
3G2	MOD
ASF	MOV
AVI	MP4
DIVX	MPG
M2T	MTS
M2TS	TOD
M4V	WMV
MKV

VIDEO 还包括如下特殊视频格式：VR 视频、慢镜头视频以及在 Google 相册应用中创建的动画。

以下示例按 PHOTO 进行过滤：

REST

{
  "filters": {
    "mediaTypeFilter": {
      "mediaTypes": [
        "PHOTO"
      ]
    }
  }
}

Java

// Create a new MediaTypeFilter for Photo media items
MediaTypeFilter mediaType = MediaTypeFilter.newBuilder()
    .addMediaTypes(MediaType.PHOTO)
    .build();
// Create a new Filters object
Filters filters = Filters.newBuilder()
    .setMediaTypeFilter(mediaType)
    .build();
// Specify the Filters object in the searchMediaItems call
SearchMediaItemsPagedResponse response = photosLibraryClient.searchMediaItems(filters);

PHP

// Create a new MediaTypeFilter for Photo media items
$filtersBuilder = new FiltersBuilder();
$filtersBuilder->setMediaType(MediaType::PHOTO);

// Make a search call with the options set in the filters builder
$response = $photosLibraryClient->searchMediaItems(
    ['filters' => $filtersBuilder->build()]
);

您无法组合使用多种媒体类型的过滤器。

已归档状态

您的用户可能已将部分照片归档。默认情况下，搜索结果中不会返回已归档的照片。如需包含已归档的内容，您可以在过滤条件中设置标志，如以下示例所示：

REST

{
  "filters": {
    "includeArchivedMedia": true
  }
}

Java

// Create a new Filters object that includes archived media
Filters filters = Filters.newBuilder()
    .setIncludeArchivedMedia(true)
    .build();

// Specify the Filters object in the searchMediaItems call
SearchMediaItemsPagedResponse response = photosLibraryClient.searchMediaItems(filters);

PHP

// Create a new Filters object that includes archived media
$filtersBuilder = new FiltersBuilder();
$filtersBuilder->setIncludeArchivedMedia(true);

// Make a search call with the options set in the filters builder
$response = $photosLibraryClient->searchMediaItems(
    ['filters' => $filtersBuilder->build()]
);

组合过滤器

不同种类的过滤器可以相互组合。系统只会返回与所有请求的功能匹配的内容。

组合过滤器时，每种过滤器类型的格式限制与单独使用时的格式限制相同。在以下示例中，仅返回已归类为 SPORT 且日期为 2014 年或 2010 年的照片：

REST

{
  "filters": {
    "contentFilter": {
      "includedContentCategories": [
        "SPORT"
      ]
    },
    "dateFilter": {
      "dates": [
        {
          "year": 2014
        },
        {
          "year": 2010
        }
      ]
    },
    "mediaTypeFilter": {
      "mediaTypes": [
        "PHOTO"
      ]
    }
  }
}

Java

// Create a new ContentFilter that only includes SPORT items
ContentFilter contentFilter = ContentFilter.newBuilder()
    .addIncludedContentCategories(ContentCategory.SPORT)
    .build();
// Create a new media type filter that only includes PHOTO media items
MediaTypeFilter mediaTypeFilter = MediaTypeFilter.newBuilder()
    .addMediaTypes(MediaType.PHOTO)
    .build();
// Create a new DateFilter that only includes items from 2010 or 2014
Date year2014 = Date.newBuilder().setYear(2014).build();
Date year2010 = Date.newBuilder().setYear(2010).build();
DateFilter dateFilter = DateFilter.newBuilder()
    .addDates(year2010)
    .addDates(year2014)
    .build();
// Create a new Filters object combining these filters
Filters filters = Filters.newBuilder()
    .setDateFilter(dateFilter)
    .setMediaTypeFilter(mediaTypeFilter)
    .setContentFilter(contentFilter)
    .build();
// Specify the Filter object in the searchMediaItems call
SearchMediaItemsPagedResponse response = photosLibraryClient.searchMediaItems(filters);

PHP

// Create a new ContentFilter
$filtersBuilder = new FiltersBuilder();
// Only include SPORT items
$filtersBuilder->addIncludedCategory(ContentCategory::SPORT);
// Only include PHOTO media items
$filtersBuilder->setMediaType(MediaType::PHOTO);
// Only include items from 2010 or 2014
$year2014 = new Date();
$year2014->setYear(2014);
$year2010 = new Date();
$year2010->setYear(2010);
$filtersBuilder->addDateRange($year2010, $year2014);

// Make a search call with the options set in the filters builder
// Filters have been combined in the filter builder
$response = $photosLibraryClient->searchMediaItems(
    ['filters' => $filtersBuilder->build()]
);

对结果进行排序

只有使用日期过滤条件的查询才能排序。

如果您未指定排序选项，则结果将按降序排序（最新的结果排在前面）。

下表显示了 orderBy 参数支持的选项：

`orderBy` 参数
`MediaMetadata.creation_time desc`	按降序（最新项优先）返回媒体项
`MediaMetadata.creation_time`	按升序返回媒体项（最早的内容排在最前面）

以下示例会返回 2017 年的所有媒体内容，并按最早到最新的时间顺序显示。

REST

{
  "filters": {
    "dateFilter": {
      "dates": [
        {
          "year": 2017
        }
      ]
    }
  },
  "orderBy": "MediaMetadata.creation_time"
}

Java

// Create a new dateFilter for the year 2017.
DateFilter dateFilter = DateFilter.newBuilder()
        .addDates(Date.newBuilder().setYear(2017))
        .build();

// Create a new Filters object
Filters filters = Filters.newBuilder()
        .setDateFilter(dateFilter)
        .build();

// Sort results by oldest item first.
final OrderBy newestFirstOrder = OrderBy.MEDIAMETADATA_CREATION_TIME;

// Specify the filter and sort order in the searchMediaItems call.
SearchMediaItemsPagedResponse response
        = photosLibraryClient.searchMediaItems(filters, newestFirstOrder);

PHP

// Create a new dateFilter for the year 2017.
$filtersBuilder = new FiltersBuilder();
$filtersBuilder->addDate((new Date())->setYear(2017));

// Make a search call with the options set in the filters builder and sort
// the results by oldest item first.
$response = $photosLibraryClient->searchMediaItems(
    [
        'filters' => $filtersBuilder->build(),
        'orderBy' => OrderBy::MEDIAMETADATA_CREATION_TIME
    ]
);
