列出文件的标签
使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
您的组织可以拥有多个标签,每个标签可以包含任意数量的字段。本页介绍了如何列出单个 Google 云端硬盘文件上的所有标签。
如需列出文件标签,请使用 files.listLabels
方法。请求正文必须为空。该方法还接受可选的查询参数 maxResults
,用于设置每页返回的标签数量上限。如果未设置,则返回 100 个结果。
如果成功,响应正文会包含应用于文件的标签列表。这些对象存在于类型为 Label
的 items
对象中。
示例
以下代码示例展示了如何使用标签的 fileId
来检索正确的标签。
Java
List<Label> labelList =
labelsDriveClient.files().listLabels("FILE_ID").execute().getItems();
Python
label_list_response = drive_service.files().listLabels(fileId="FILE_ID").execute();
Node.js
/**
* Lists all the labels on a Drive file
* @return{obj} a list of Labels
**/
async function listLabels() {
// Get credentials and build service
// TODO (developer) - Use appropriate auth mechanism for your app
const {GoogleAuth} = require('google-auth-library');
const {google} = require('googleapis');
const auth = new GoogleAuth({scopes: 'https://www.googleapis.com/auth/drive'});
const service = google.drive({version: 'v3', auth});
try {
const labelListResponse = await service.files.listLabels({
fileId: 'FILE_ID',
});
return labelListResponse;
} catch (err) {
// TODO (developer) - Handle error
throw err;
}
}
将 FILE_ID 替换为您要获取标签列表的文件的 fileId
。

This page describes how to list all labels on a single Google Drive\nfile.\n\nTo list the file labels, use the\n[`files.listLabels`](/workspace/drive/api/v2/reference/files/listLabels) method. The\nrequest body must be empty. The method also takes the optional query parameter\n`maxResults` to set the maximum number of labels to return per page. If not set,\n100 results are returned.\n\nIf successful, the [response\nbody](/workspace/drive/api/reference/rest/v2/files/listLabels#response-body) contains the\nlist of labels applied to a file. These exist within an `items` object of type\n[`Label`](/workspace/drive/api/reference/rest/v2/Label).\n\nExample\n-------\n\nThe following code sample shows how to use the label's `fileId` to retrieve the\ncorrect labels. \n\n### Java\n\n List\u003cLabel\u003e labelList =\n labelsDriveClient.files().listLabels(\"\u003cvar translate=\"no\"\u003eFILE_ID\u003c/var\u003e\").execute().getItems();\n\n### Python\n\n label_list_response = drive_service.files().listLabels(fileId=\"\u003cvar translate=\"no\"\u003eFILE_ID\u003c/var\u003e\").execute();\n\n### Node.js\n\n /**\n * Lists all the labels on a Drive file\n * @return{obj} a list of Labels\n **/\n async function listLabels() {\n // Get credentials and build service\n // TODO (developer) - Use appropriate auth mechanism for your app\n\n const {GoogleAuth} = require('google-auth-library');\n const {google} = require('googleapis');\n\n const auth = new GoogleAuth({scopes: 'https://www.googleapis.com/auth/drive'});\n const service = google.drive({version: 'v3', auth});\n try {\n const labelListResponse = await service.files.listLabels({\n fileId: '\u003cvar translate=\"no\"\u003eFILE_ID\u003c/var\u003e',\n });\n return labelListResponse;\n } catch (err) {\n // TODO (developer) - Handle error\n throw err;\n }\n }\n\nReplace \u003cvar translate=\"no\"\u003eFILE_ID\u003c/var\u003e with the `fileId` of the file for which you\nwant the list of labels."]]
