Settings
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。
google.maps.Settings 类
用于控制 Maps JavaScript API 整体行为的设置。
通过调用 const {Settings} = await google.maps.importLibrary("core") 进行访问。请参阅 Maps JavaScript API 中的库。
静态方法 |
|---|
getInstance |
getInstance()
参数：无
返回 google.maps.Settings 的单例实例。 |
属性 |
|---|
 experienceIds |
一组用于归因 Google 地图 JS API 调用的唯一体验 ID。返回值是存储在 Settings 类单例实例中的内部值的副本。因此，对 google.maps.Settings.getInstance().experienceIds 的操作只会修改副本，而不会修改内部值。
如需更新内部值，请将该属性设置为单例实例上的新值（例如 google.maps.Settings.getInstance().experienceIds = [experienceId];）。 |
fetchAppCheckToken |
返回一个解析为 Firebase App Check 令牌结果的 promise。该令牌会作为“X-Firebase-AppCheck”HTTP 标头附加到 gRPC 请求。如果令牌为空，则不会附加标头。 |
google.maps.MapsAppCheckTokenResult 接口
用于描述 Firebase App Check 令牌结果。
