redis2-nginx-module问题

qq3056

location /pipelined {
    redis2_query set hello world;
    redis2_query get hello;

    redis2_pass 127.0.0.1:$TEST_NGINX_REDIS_PORT;
}

then GET /pipelined will yield two successive raw Redis responses

+OK
$5
world

输出的$5如何去掉？

貌似你没把那篇文档看全。在这里引用一下相关的原文：

“This module returns the raw TCP response from the Redis server. It's
recommended to use my LuaRedisParser (written in pure C) to parse
these responses into lua data structure when combined with
HttpLuaModule.

When used in conjunction with HttpLuaModule, it is recommended to use
the lua-resty-redis library instead of this module though, because the
former is much more flexible and memory-efficient.”

这个模块返回的是原生的协议，建议直接用lua-resty-redis模块。

谢谢。

不过我程序里用了

ngx.location.capture("/conn_redis", {args = { key=key} })

而且也用了upstream

如果用lua-resty-redis模块，改动量太大了。

难道只能我对输出结果过滤一下？

貌似你还是没有看全。我再最后引用一遍你（可能）仍然忽略掉的那一段：

“This module returns the raw TCP response from the Redis server. It's
recommended to use my LuaRedisParser (written in pure C) to parse
these responses into lua data structure when combined with
HttpLuaModule.”

万分感谢。已经好了。

所以说，最终必须用lua？

我觉得用Lua 是比较好的方法
