我应该在 ruby​​ 中获取多维数组

Answer 1

您需要使用 YAML标准库:

require 'yaml'

a = "[[43.632526509656685,-79.42367434501648],[43.64327275111337,-79.37912821769714]]"
YAML.load(a)
# => [[43.632526509656685, -79.42367434501648],
#     [43.64327275111337, -79.37912821769714]]

或使用 JSON标准库。

require 'json'

a = "[[43.632526509656685,-79.42367434501648],[43.64327275111337,-79.37912821769714]]"
JSON.parse(a)
# => [[43.632526509656685, -79.42367434501648],
#     [43.64327275111337, -79.37912821769714]]
