Question

所以我有这个代码读取文件并检查某个值，如果找到这些单词，关键字将被写入json文件。除了问题是它写了一个不必要的值。

require 'json'

lines = IO.readlines('dhcpd.conf')
host = nil
eth = nil
address = nil

hosts = {}

lines.each do |line|
  if line =~ /^host\s+(.+)\s+{$/
   host = $1
   eth = nil
   address = nil

  elsif line =~ /^\s*hardware ethernet (.*);$/
   eth = $1
  elsif line =~ /^\s*fixed-address (.*);$/
   address = $1
  elsif line =~ /^}$/
   hosts[host] = {name: host, mac: eth, ip: address}
 end
end

file = File.new("new_computers.json", "w")
file.puts "["
file.puts JSON.pretty_generate(hosts)
file.puts "]"

这是我得到的输出：

[
 {
   "Mike": {
    "name": "Mike",
    "mac": "a1:b2:c3:d4:e5:f6",
    "ip": "192.168.1.1"
 },
   "Mike2": {
    "name": "Mike2",
    "mac": "aa:bb:cc:dd:ee:ff",
    "ip": "192.168.1.2"
 },
 ...
 ...
 ...
]

但希望输出为：

[
 {
   "name" : "Mike"
   "mac" : "a1:b2:c3:d4:e5:f6"
   "ip" : "192.168.1.1"
 },
...
...
...
]

我尝试了各种各样的事情，但我无法做到。

First change $.post to array, if you are not using index.php as Hash in other places.

session_start();
$_SESSION = array();
session_unset();
session_destroy();
session_write_close();
session_regenerate_id(true);

Then while adding to the hosts do this, if you are interested in only hosts, hosts, hosts = [] and not :name as key in file

:mac

Change writing logic to

:ip

Should see the expected data

ruby json.pretty_generate输出
