是的……至少在 2.6 中。您可以在 LUA 脚本中执行此操作,并且只需让 LUA 脚本返回一个空结果。这里使用的是 bookleeve 客户端:
const int DB = 0; // any database number
// prime some initial values
conn.Keys.Remove(DB, new[] {"a", "b", "c"});
conn.Strings.Increment(DB, "b");
conn.Strings.Increment(DB, "c");
conn.Strings.Increment(DB, "c");
// run the script, passing "a", "b", "c", "c" to
// increment a & b by 1, c twice
var result = conn.Scripting.Eval(DB,
@"for i,key in ipairs(KEYS) do redis.call('incr', key) end",
new[] { "a", "b", "c", "c"}, // <== aka "KEYS" in the script
null); // <== aka "ARGV" in the script
// check the incremented values
var a = conn.Strings.GetInt64(DB, "a");
var b = conn.Strings.GetInt64(DB, "b");
var c = conn.Strings.GetInt64(DB, "c");
Assert.IsNull(conn.Wait(result), "result");
Assert.AreEqual(1, conn.Wait(a), "a");
Assert.AreEqual(2, conn.Wait(b), "b");
Assert.AreEqual(4, conn.Wait(c), "c");
或者要对incrby 做同样的事情,将“by”数字作为参数传递,将中间部分更改为:
// run the script, passing "a", "b", "c" and 1, 1, 2
// increment a & b by 1, c twice
var result = conn.Scripting.Eval(DB,
@"for i,key in ipairs(KEYS) do redis.call('incrby', key, ARGV[i]) end",
new[] { "a", "b", "c" }, // <== aka "KEYS" in the script
new object[] { 1, 1, 2 }); // <== aka "ARGV" in the script
