Nginx+Lua+Redis构建高并发Web应用

                    redis2_query hgetall $key;
                    redis2_pass redis_pool;
                }

                location /json {
                    content_by_lua_file conf/test_redis.lua;
                }
            }
        }

三、测试
1、编写脚本
        编写上面配置中的test_redis.lua脚本

        #vi test_redis.lua
        local json = require("json")
        local parser = require("redis.parser")
        local res = ngx.location.capture("/get_redis",{args = { key = ngx.var.arg_key }})
        if res.status == 200 then
            reply = parser.parse_reply(res.body)
            value = json.encode(reply)
            ngx.say(value)
            a = json.decode(value)
            ngx.say(a[2])
        end

2、构造数据

        #redis-cli -h 192.168.1.105 -p 6379
        redis 192.168.1.105:6379>HMSET testnlr www www.joyvc.cn mail mail.joyvc.cn

3、开始测试

        #curl 'http://192.168.1.104/json?key=testnlr'
        ["www", "www.joyvc.cn", "mail", "mail.joyvc.cn"]
