我有一個存盤在檔案中的陣列，當我將此檔案讀取到 Ruby 中的變數時，它會在陣列的開頭和結尾回傳雙引號。我使用 Ruby 2.7.0
irb
irb(main):065:0> ports = IO.read('/ports_values')
irb(main):066:0> ports
=> "['127.0.0.1:6601:6601', '127.0.0.1:8000:8000', '127.0.0.1:7200:7200', '127.0.0.1:9201:9201', '5606:5606', '6304:6504', '6305:6505']"
但我需要這個：
irb(main):066:0> ports
=> ['127.0.0.1:6601:6601', '127.0.0.1:8000:8000', '127.0.0.1:7200:7200', '127.0.0.1:9201:9201', '5606:5606', '6304:6504', '6305:6505']
沒有雙引號，我試過了，但沒有用
irb(main):067:0> ports.gsub /"/, ' '
=> "['127.0.0.1:6601:6601', '127.0.0.1:8000:8000', '127.0.0.1:7200:7200', '127.0.0.1:9201:9201', '5606:5606', '6304:6504', '6305:6505']"
uj5u.com熱心網友回復：
a = "['127.0.0.1:6601:6601', '127.0.0.1:8000:8000', '127.0.0.1:7200:7200', '127.0.0.1:9201:9201', '5606:5606', '6304:6504', '6305:6505']"
a.slice(1..-2).split(",").map{ |b| b.strip.gsub("'","")}
o/p：["127.0.0.1:6601:6601", "127.0.0.1:8000:8000", "127.0.0.1:7200:7200", "127.0.0.1:9201:9201", "5606:5606", "6304:6504", "6305:6505"]
