解决了的。解决方案如下,多亏了@hobbs,我才纠正了它。
我正在使用node_redis包。
下面是我如何通过cli使用zrangebylex命令。
127.0.0.1:6379> zadd movie 0 "Creed:2015:id1"
(integer) 1
127.0.0.1:6379> zadd movie 0 "Secret in Their Eyes:2015:id2"
(integer) 1
127.0.0.1:6379> zadd movie 0 "Spotlight:2015:id3"
(integer) 1
127.0.0.1:6379> zadd movie 0 "The Lobster:2015:id4"
(integer) 1
127.0.0.1:6379> zadd movie 0 "The Corpse of Anna Fritz:2015:id5"
(integer) 1
127.0.0.1:6379> zadd movie 0 "The Martian:2015:id6"
(integer) 1
127.0.0.1:6379> zadd movie 0 "The Revenant:2015:id7"
(integer) 1
127.0.0.1:6379> zadd movie 0 "Steve Jobs:2015:id8"
(integer) 1
所有以“那个”开头的电影。
127.0.0.1:6379> zrangebylex movie "[The" "(The\xff"
1) "The Corpse of Anna Fritz:2015:id5"
2) "The Lobster:2015:id4"
3) "The Martian:2015:id6"
4) "The Revenant:2015:id7"
到目前为止,还不错。
前两项。
zrangebylex movie "[The" "(The\xff" limit 0 2
1) "The Corpse of Anna Fritz:2015:id5"
2) "The Lobster:2015:id4"
我试图对node.js做同样的事情,但是我得到了一个错误。
var redis = require("redis");
var client = redis.createClient();
app.get('/redis', function(req, res) {
var args2 = ["movie", "The", "The", 'LIMIT', 0, 2];
client.zrangebylex(args2, function(err, response) {
if (err) throw err;
console.log(response);
});
});
这是完整的错误日志。

解决方案
app.get('/redis', function(req, res) {
var args2 = ["movie", "[The", '(The\xff', 'LIMIT', "0", "2"];
client.zrangebylex(args2, function(err, response) {
if (err) throw err;
console.log(response);
res.end();
});
});
最佳答案
您没有发送相同的参数-特别是您的范围没有ZRANGEBYLEX
限制所需的“(”或“[”字符。也不包括上限上的\xff
。
关于node.js - node_redis ZRANGEBYLEX返回“ERR min或max无效字符串范围项”错误,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/35423985/
