如何格式化node_redis信息功能輸出？

Question

我想檢查我的電腦與節點Redis信息，所以我用node_redis和運行info功能：

var redis = require("redis"), 
    client = redis.createClient(); 

client.on("connect", function() { 
    client.info(function (err, replay) { 
     console.log(replay); 
    }) 
}) 

但響應聯合國格式：

`#Server\r\nredis_version:2.6.16\r\nredis_git_sha1:00000000\r\nredis_git_dirty:0\r\nredis_mode:standalone\r\nos:Linux 3.8.0-29-generic x86_64\r\narch_bits:64\r\nmultiplexing_api:epoll\r\ngcc_version:4.6.3\r\nprocess_id:2941\r\nrun_id:e60f261a6f4f6f081563a47961315eff6b1c005d\r\ntcp_port:6379\r\nuptime_in_seconds:1777\r\nuptime_in_days:0\r\nhz:10\r\nlru_clock:2040689\r\n\r\n# Clients\r\nconnected_clients:2\r\nclient_longest_output_list:0\r\nclient_biggest_input_buf:0\r\nblocked_clients:0\r\n\r\n# Memory\r\nused_memory:562584\r\nused_memory_human:549.40K\r\nused_memory_rss:2031616\r\nused_memory_peak:561784\r\nused_memory_peak_human:548.62K\r\nused_memory_lua:31744\r\nmem_fragmentation_ratio:3.61\r\nmem_allocator:jemalloc-3.2.0\r\n\r\n# Persistence\r\nloading:0\r\nrdb_changes_since_last_save:0\r\nrdb_bgsave_in_progress:0\r\nrdb_last_save_time:1383553917\r\nrdb_last_bgsave_status:ok\r\nrdb_last_bgsave_time_sec:-1\r\nrdb_current_bgsave_time_sec:-1\r\naof_enabled:0\r\naof_rewrite_in_progress:0\r\naof_rewrite_scheduled:0\r\naof_last_rewrite_time_sec:-1\r\naof_current_rewrite_time_sec:-1\r\naof_last_bgrewrite_status:ok\r\n\r\n# Stats\r\ntotal_connections_received:3\r\ntotal_commands_processed:5\r\ninstantaneous_ops_per_sec:0\r\nrejected_connections:0\r\nexpired_keys:0\r\nevicted_keys:0\r\nkeyspace_hits:0\r\nkeyspace_misses:0\r\npubsub_channels:0\r\npubsub_patterns:0\r\nlatest_fork_usec:0\r\n\r\n# Replication\r\nrole:master\r\nconnected_slaves:0\r\n\r\n# CPU\r\nused_cpu_sys:0.13\r\nused_cpu_user:0.19\r\nused_cpu_sys_children:0.00\r\nused_cpu_user_children:0.00\r\n\r\n# Keyspace\r\n' 

我怎麼能拒絕它到一個對象？像：

{ 
    redis_version:2.6.16, 
    redis_git_sha1:00000000, 
    redis_git_dirty:0, 
    ...... 
} 

，這樣我可以讀取每個屬性的值，獲取信息，我需要

Answer 1

檢查this問題。基本上，您需要編寫一個簡單的解析器，如第一個答案中提供的解析器。

Answer 2

您可以使用node-redis-info：

npm install redis-info 

用法：

> var parser = require('redis-info'); 
undefined 
> var info = parser.parse(redis_info_str); 
undefined 
> info.fields.redis_version 
2.6.1 
> info.startWith('pubsub') 
[ [ 'pubsub_channels', '2' ], 
    [ 'pubsub_patterns', '0' ] ] 
> info.contains('memory') 
[ [ 'used_memory', '15080416' ], 
    [ 'used_memory_human', '14.38M' ], 
    [ 'used_memory_rss', '21258240' ], 
    [ 'used_memory_peak', '18985904' ], 
    [ 'used_memory_peak_human', '18.11M' ] ]
