如需更新数据集的相关信息，请向修补数据集端点发送 HTTP PATCH 请求，其中还包含数据集的 ID：
https://mapsplatformdatasets.googleapis.com/v1/projects/PROJECT_NUMBER_OR_ID/datasets/DATASET_ID
您可以更新数据集的 displayName 和/或 description 属性。
例如：
curl -X PATCH -d '{
"displayName": "My Updated Dataset",
"description": "This is an updated description"
}' \
-H 'X-Goog-User-Project: PROJECT_NUMBER_OR_ID' \
-H "Content-Type: application/json" \
-H "Authorization: Bearer $TOKEN" \
"https://mapsplatformdatasets.googleapis.com/v1/projects/PROJECT_NUMBER_OR_ID/datasets/f57074a0-a8b6-403e-9df1-e8a9e4f9fc46"该请求会返回更新后的数据集的相关信息：
{
"name": "projects/PROJECT_NUMBER_OR_ID/datasets/f57074a0-a8b6-403e-9df1-e8a9e4f9fc46",
"displayName": "My Updated Dataset",
"description": "This is an updated description",

指定字段掩码
默认情况下，更新会修改请求正文中指定的所有受支持字段，即 displayName 和 description。不过，您还可以在请求中添加 updateMask 查询参数，以明确指定要更新的请求正文中的字段。
使用 updateMask 指定要更新的字段的完全限定名称的逗号分隔列表。例如，如需仅更新 displayName 字段，请执行以下操作：
curl -X PATCH -d '{
"displayName": "My Updated Dataset",
"description": "This is an updated description"
}' \
-H 'X-Goog-User-Project: PROJECT_NUMBER_OR_ID' \
-H "Content-Type: application/json" \
-H "Authorization: Bearer $TOKEN" \
"https://mapsplatformdatasets.googleapis.com/v1/projects/PROJECT_NUMBER_OR_ID/datasets/f57074a0-a8b6-403e-9df1-e8a9e4f9fc46?updateMask=displayName"updateMask 查询参数的默认值为 *，表示更新请求正文中指定的所有受支持字段。
