Ruby - 将json格式化为字符串

Question

我需要将JSON响应转换为格式良好的字符串，更像是表格。

实施例，

[{id: 1, name: "Panda", description: ""}, {id: 2, name: "koala", description: ""},...]

转换为，

 Id       | Name        |Description
 1        | Panda       |
 2        | Koala test  | 

并将文本自动包装在单元格宽度内。 任何帮助，将不胜感激。 谢谢。

Answer 1

First you need to parse JSON result.

data = JSON.parse(result)

Then use that parsed result to generate the pattern.

data = [
  { id: 1, name: 'Panda', description: '' },
  { id: 2, name: 'koala', description: '' }
]

puts 'Id      | Name         |Description'
data.each do |entry|
  puts "#{entry[:id]}       | #{entry[:name]}        |#{entry[:description]}"
end

Hope this helps!
