GEORADIUSBYMEMBER key member radius m|km|ft|mi [WITHCOORD] [WITHDIST] [WITHHASH] [COUNT count] [ASC|DESC] [STORE key] [STOREDIST key]

自3.2.0起可用。

时间复杂度: O(N + log(M))其中N是由中心和半径界定的圆形区域的边界框内的元素的数量,M 是索引内的项目的数量。

该命令与 GEORADIUS 完全相同,唯一的区别在于,它不是以查询区域的中心为经度和纬度值,而是采用已存在于有序集合所代表的地理空间索引内的成员的名称。

指定成员的位置用作查询的中心。

请查看下面的示例和 GEORADIUS 文档以获取有关该命令及其选项的更多信息。

请注意,GEORADIUSBYMEMBER_RO自 Redis 3.2.10 和 Redis 4.0.0 以来,为了提供可用于从服务器的只读命令,此功能也可用。有关更多信息,请参阅 GEORADIUS 页面。
