Method: projects.listAssets
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。
HTTP 请求
GET https://earthengine.googleapis.com/v1/{parent=projects/*}:listAssets
网址采用 gRPC 转码语法。
路径参数
| 参数 |
parent |
string
必需。要列出的容器素材资源的名称。parent 的格式为“projects/*”或“projects/*/assets/**”（例如“projects/[PROJECT]”或“projects/earthengine-legacy/assets/users/[USER]/[ASSET]”。所有用户拥有的资产目前都位于项目“earthengine-legacy”下（例如，“projects/earthengine-legacy/assets/users/foo/bar”）。所有其他资产均位于项目“earthengine-public”下（例如“projects/earthengine-public/assets/LANDSAT”）。如果指定了“projects/earthengine-legacy”，则响应将包含请求用户拥有的所有顶级文件夹的列表。
必须对指定的资源 parent 具有以下一项或多项 IAM 权限才能进行授权：
earthengine.assets.getearthengine.assets.list
|
查询参数
| 参数 |
pageSize |
integer
每页的结果数上限。服务器返回的素材资源数量可能少于请求的数量。如果未指定，默认每页数据大小取决于 EarthEngineAssetView，限制越严格的视图，上限越高。
|
pageToken |
string
标识服务器应返回的结果页面的令牌。 通常，这是上次调用 projects.listAssets 方法返回的 ListAssetsResponse.next_page_token 值。
|
filter |
string
指定过滤器（如果有）。过滤条件仅应用于 ImageCollection 素材资源，系统会忽略 Folder 素材资源。 系统会识别 startTime、endTime 字段以及 properties 的成员。可使用自定义函数 intersects(str)，以按几何图形进行过滤。 日期过滤条件示例：
"startTime>\"2020-01-01T00:00:00+00:00\" AND
endTime<\"2020-02-01T00:00:00+00:00\""
属性过滤条件示例：
"properties.CLOUDY_PIXEL_PERCENTAGE<30"
几何图形过滤器示例：
"intersects(\"{'type':'Point','coordinates':[1,2]}\")"
"intersects(\"{\\\"type\\\":\\\"Point\\\",\\\"coordinates\\\":[1,2]}\")"
如需详细了解过滤器语言，请参阅 https://google.aip.dev/160。
|
view |
enum (EarthEngineAssetView)
指定应在响应中返回 EarthEngineAsset 资源的哪些部分。仅适用于 ImageCollection 素材资源。无论此字段的值如何，Folder 资源的所有元素都将在 BASIC 视图中编码。
|
响应正文
如果成功，则响应正文包含一个 ListAssetsResponse 实例。
