SCRIPT EXISTS sha1 [sha1 ...]

自2.6.0起可用。

时间复杂度: O(N),其中N是要检查的脚本的数量(因此检查单个脚本是O(1)操作)。

返回脚本缓存中有关脚本存在的信息。

该命令接受一个或多个 SHA1 摘要,并返回一个1或0的列表,以指示脚本是否已经定义或不在脚本缓存中。在流水线操作之前,这可以确保加载脚本(如果不加载,则使用 SCRIPT LOAD 加载它们),以便可以仅使用 EVALSHA 而不是 EVAL 来执行流水线操作以节省带宽。

有关 Redis Lua 脚本的详细信息,请参阅 EVAL 文档。

返回值

Array reply  命令返回与指定的 SHA1 摘要参数对应的整数数组。对于脚本缓存中实际存在的脚本的每个对应 SHA1 摘要,返回1,否则返回0。
