爲elasticsearch索引解析文本並獲取索引值

在下面的部分中，我需要爲每個節選擇輸出的第一個條目，而每個節又是ElasticSearch索引的名稱。爲elasticsearch索引解析文本並獲取索引值

例如nprod @ n_docs，平臺的API級，nprod @ janeuk_classic，nprod @ delista.com @ 1

所以我知道他們是字符模式之間像

{「

和

：{ 「設置」：{

那麼我的腳本會如何抓取這些值，以便我可以將它們發送到另一個文件？

我的輸出看起來像：

這是JSON。閱讀數據並使用JSON::XS解析它。

use JSON::XS qw(decode_json); 

my $file; 
{ 
    open(my $fh, '<:raw', $qfn) 
     or die("Can't open \"$qfn\": $!\n"); 
    local $/; 
    $file = <$fh>; 
} 

my $data = decode_json($file);

然後，只是遍歷樹的信息，你想要的。

my @index_names = keys(%$data);
