列出 DriveItem 的缩略图

项目
07/04/2024

命名空间：microsoft.graph

检索 DriveItem 资源的 ThumbnailSet 资源集合。

DriveItem 可以由零个或多个 ThumbnailSet 资源表示。每个 thumbnailSet 都可以有一个或多个 thumbnail 对象，此类对象是表示项目的图像。例如，thumbnailSet 可包括 thumbnail 对象，例如包括 small、medium 或 large 等常见对象。

可以通过多种方式在 OneDrive 上对缩略图进行操作。以下是一些最常见的操作：

枚举项目的可用缩略图
检索项目的单个缩略图
检索缩略图的内容
在单个请求中检索多个项目的缩略图
检索自定义缩略图的大小
上载项目的自定义缩略图
确定是否存在自定义的上传缩略图

此 API 可用于以下国家级云部署。

示例

以下示例显示了一个请求，该请求检索当前用户的 OneDrive 中某个项的可用缩略图。

GET /me/drive/items/{item-id}/thumbnails


// Code snippets are only available for the latest version. Current version is 5.x

// To initialize your graphClient, see https://learn.microsoft.com/en-us/graph/sdks/create-client?from=snippets&tabs=csharp
var result = await graphClient.Drives["{drive-id}"].Items["{driveItem-id}"].Thumbnails.GetAsync();



mgc drives items thumbnails list --drive-id {drive-id} --drive-item-id {driveItem-id}



// Code snippets are only available for the latest major version. Current major version is $v1.*

// Dependencies
import (
	  "context"
	  msgraphsdk "github.com/microsoftgraph/msgraph-sdk-go"
	  //other-imports
)


// To initialize your graphClient, see https://learn.microsoft.com/en-us/graph/sdks/create-client?from=snippets&tabs=go
thumbnails, err := graphClient.Drives().ByDriveId("drive-id").Items().ByDriveItemId("driveItem-id").Thumbnails().Get(context.Background(), nil)


// Code snippets are only available for the latest version. Current version is 6.x

GraphServiceClient graphClient = new GraphServiceClient(requestAdapter);

ThumbnailSetCollectionResponse result = graphClient.drives().byDriveId("{drive-id}").items().byDriveItemId("{driveItem-id}").thumbnails().get();


const options = {
	authProvider,
};

const client = Client.init(options);

let thumbnails = await client.api('/me/drive/items/{item-id}/thumbnails')
	.get();


<?php
use Microsoft\Graph\GraphServiceClient;


$graphServiceClient = new GraphServiceClient($tokenRequestContext, $scopes);


$result = $graphServiceClient->drives()->byDriveId('drive-id')->items()->byDriveItemId('driveItem-id')->thumbnails()->get()->wait();


Import-Module Microsoft.Graph.Files

Get-MgDriveItemThumbnail -DriveId $driveId -DriveItemId $driveItemId


# Code snippets are only available for the latest version. Current version is 1.x
from msgraph import GraphServiceClient
# To initialize your graph_client, see https://learn.microsoft.com/en-us/graph/sdks/create-client?from=snippets&tabs=python

result = await graph_client.drives.by_drive_id('drive-id').items.by_drive_item_id('driveItem-id').thumbnails.get()

这将返回项的可用 thumbnailSet 的数组。驱动器中的任何项都可以有零个或多个缩略图。

注意：可以使用 select 查询字符串参数，控制在 ThumbnailSet 中返回的缩略图尺寸。例如，/thumbnails?select=medium 仅检索中等大小的缩略图。

响应

HTTP/1.1 200 OK
Content-type: application/json

Path 参数

名称	类型	说明
item-id	string	引用的项目的唯一标识符。
thumb-id	数字	缩略图的索引，通常介于 0 到 4 之间。如果没有自定义缩略图，索引为 0。
size	string	请求获取的缩略图的尺寸。可取值为下面列出的标准大小之一或自定义大小。

HTTP/1.1 200 OK

检索缩略图的二进制内容

可以通过请求缩略图的 content 属性直接检索缩略图的内容。

响应

本服务通过到缩略图 URL 的重定向进行响应。

HTTP/1.1 302 Found
Location: https://b0mpua-by3301.files.1drv.com/y23vmagahszhxzlcvhasdhasghasodfi

缩略图 URL 具有缓存安全性。如果在项发生更改后需要生成新的缩略图，URL 将会更改。

获取缩略图的同时列出 DriveItem

如果检索要显示的 DriveItem 资源的列表，可以使用 $expand 查询字符串参数，以便同时包含这些资源的缩略图。这使你的应用可以通过一个请求同时检索缩略图和项，而不是发出多个请求。

HTTP 请求

响应

本服务通过 DriveItem 及其缩略图的列表进行响应。

HTTP/1.1 200 OK

}

大小选项

下表定义了可能的缩略图大小。虽然可以请求任意的缩略图大小，但可能存在定义的有并迅速返回值：

名称	分辨率	纵横比	说明
`small`	96 longest	Original	小型的高压缩缩略图，裁剪为正方形纵横比。
`medium`	176 longest	Original	裁剪为 OneDrive Web 视图的标准项目大小。
`large`	800 longest	Original	最长边重设为 800 像素的缩略图。
`smallSquare`	96x96	方形裁剪	小方形缩略图
`mediumSquare`	176x176	方形裁剪	小方形缩略图
`largeSquare`	800x800	方形裁剪	大方形缩略图

请求自定义缩略图的大小

除了定义尺寸外，应用还可以指定前缀为 c 的缩略图尺寸，从而请求获取自定义缩略图尺寸。例如，如果你的应用需要 300x400 的缩略图，可以按如下所示请求获取此大小：

GET /me/drive/items/{item-id}/thumbnails?select=c300x400_crop


// Code snippets are only available for the latest version. Current version is 5.x

// To initialize your graphClient, see https://learn.microsoft.com/en-us/graph/sdks/create-client?from=snippets&tabs=csharp
var result = await graphClient.Drives["{drive-id}"].Items["{driveItem-id}"].Thumbnails.GetAsync((requestConfiguration) =>
{
	requestConfiguration.QueryParameters.Select = new string []{ "c300x400_crop" };
});



mgc drives items thumbnails list --drive-id {drive-id} --drive-item-id {driveItem-id}

// Dependencies

}

// To initialize your graphClient, see https://learn.microsoft.com/en-us/graph/sdks/create-client?from=snippets&tabs=go

// Code snippets are only available for the latest version. Current version is 6.x

GraphServiceClient graphClient = new GraphServiceClient(requestAdapter);

ThumbnailSetCollectionResponse result = graphClient.drives().byDriveId("{drive-id}").items().byDriveItemId("{driveItem-id}").thumbnails().get(requestConfiguration -> {
	requestConfiguration.queryParameters.select = new String []{"c300x400_crop"};
});


const options = {
	authProvider,
};

const client = Client.init(options);

let thumbnails = await client.api('/me/drive/items/{item-id}/thumbnails?select=c300x400_crop')

# Code snippets are only available for the latest version. Current version is 1.x

query_parameters = query_params,
)

result = await graph_client.drives.by_drive_id('drive-id').items.by_drive_item_id('driveItem-id').thumbnails.get(request_configuration = request_configuration)

响应只包含选定的自定义缩略图尺寸：

HTTP/1.1 200 OK
Content-Type: application/json

{
  "value": [
    {
      "id": "0",
      "c300x400_crop": { "height": 300, "width": 400, "url": "https://sn3302files.onedrive.com/123"},
    }
  ]
}

可以在请求获取的缩略图尺寸后指定以下选项：

自定义标识符示例

缩略图标识符	分辨率	纵横比	说明
c300x400	300x400 像素框	原始大小	生成适应在 300x400 像素框中显示的缩略图，纵横比不变
c300x400_crop	300x400	已裁剪	生成 300x400 像素缩略图。具体方式为，重设图像大小以填充 300x400 框，并裁剪超出框外的内容。

注意：返回的缩略图可能与请求的像素尺寸不完全匹配，但与纵横比匹配。在某些情况下，如果缩略图已经存在并且可以轻松缩放来匹配请求的分辨率，则可能会返回比请求的大小更大的缩略图。

备注

注意在 OneDrive for Business 和 SharePoint 中：

使用这些调用展开缩略图集合不适用于：

GET /drive/root:/{item-path}?expand=children(expand=thumbnails)
GET /drive/items/{item-id}/children?expand=thumbnails

SharePoint Server 2016 不支持缩略图。
