GEODIST key member1 member2 [unit]

自3.2.0起可用。

时间严重年夜度: O(log(N))

前往排序荟萃体现的地理空间索引中两个成员之间的距离。

给定一个体现地理空间索引的有序荟萃,该荟萃应用 GEOADD 敕令填充,该敕令前往指订单元中两个指定成员之间的距离。

华夏棋牌假定一个或两个成员都缺掉落,则该敕令前往 NULL 。

该单元必须是以下之一,而且默许为米:

  • m 为米。

  • km 为千米。

  • mi 为英里。

  • ft 为英尺。

华夏棋牌假定地球是一个完善的球体,盘算距离,是以在边缘情形下能够泛起高达0.5%的误差。

前往值

批量字符串回复,详细为:

该敕令以指订单元的双精度值(以字符串体现)前往距离,假定缺乏一个或两个元素,则前往 NULL 。

例子

redis>  GEOADD Sicily 13.361389 38.115556 "Palermo" 15.087269 37.502669 "Catania" (integer) 2 

redis>  GEODIST Sicily Palermo Catania "166274.1516"
