Javascript将多行字符串拆分为对象

Question

我需要帮助。 我有字符串:

let str = `123.123.123.123|admin|admin|Russian Federation (RU)||SPEED: 5
123.123.123.13|user|user|Russian Federation (RU)||SPEED: 5
123.123.121.3|fpt|user|Russian Federation (RU)||SPEED: 5`

我想要:

ssh_config = [ {
  host: '123.123.123.123',
  port: 22,
  username: 'admin',
  password: 'admin'
},
{
   host: '123.123.123.13',
   port: 22,
   username: 'user',
   password: 'user'
},
{
   host: '123.123.121.3',
   port: 22,
   username: 'fpt',
   password: 'user'
}]

请帮忙。非常感谢。 我不知道用 JavaScript 编写它。

按新行拆分字符串，将结果映射到按 | 符号划分的元素，简化为包含预期字段的对象。

let str = `123.123.123.123|admin|admin|Russian Federation (RU)||SPEED: 5
123.123.123.13|user|user|Russian Federation (RU)||SPEED: 5
123.123.121.3|fpt|user|Russian Federation (RU)||SPEED: 5`;
// [p]roperties, [t]emplate, [f]unction, [s]tring, [l]ine, [a]ccumulator, [e]lement, [i]ndex
const p = ['host', 'username', 'password'], t = () => ({ port: 22 });
const f = s => s.split('\n').map(l => l.split('|').reduce((a, e, i) => (i in p && (a[p[i]] = e), a), t()));

console.log(f(str))
