从Json中搜索值中的特定字符串，并在ruby中分配给变量

这是我的json文件

{
  "osNameSpace" : "prod",
  "bucketNames" : [ "RC_osbackup_config_d0007cz_idfdafa3", "IC_osbackup_vman_d0007cz_dasdc3w" ],
  "user" : "RC_osbackup_svc_user_d0007cz_dasf2fd",
  "userOcid" : "rcid1.user.oc1..aaaaaaaazf5e27hbpst2pxarisi5qvkmgotwm5ro4nhjkkjq4mmxengckv2a",
  "group" : "RC_osbackup_svc_grp_d0007cz_asdf24"
}

我想搜索字符串“osbackup\u config”并分配给“os\u conf”变量。字符串“osbackup_vman”与“os_vman”类似

我尝试了以下方法，但没有成功

input_file="/root/testjson_2.json"
r = JSON.parse(File.read(input_file))

r["bucketNames"].find {|r1| r1['dbbackup_rman']=='rman'}['rman_bucket_name']
r["bucketNames"].find {|r1| r1['dbbackup_config']=='config'}['config_bucket_name']

为什么不是这个

r['bucketNames'].find { |v| v.include?'osbackup_config' }

或

注意你的空间。r['bucketNames']。查找{str | str.include？'osbackup_config'}

os_conf  = r['bucketNames'].find { |v| v['osbackup_config'] }

osbackup_vman = r['bucketNames'].find { |v| v['osbackup_vman'] }
