    'Event Type': 'HITExpired',
    'Event Time': '2014-10-14T08:00:05Z',
    'HIT Type ID': '3UY3BQX0VV1BL434D90TUMKT09C20F',

Answer 1

a = {}; str.replace(/^\s+([^:\n]*):\s*(.*)$/mg, function(_, k, v) { a[k] = v; })

在此之后，a将是您想要的结构。 replace将为每个匹配调用一次该函数，该模式是以一些空格开头的行，一个键，一个冒号，可能还有一些空格，然后是一个值;该函数只会将键和值填充到对象a中。

编辑：修复了愚蠢的错误。另外，我假设只有所需的行会缩进。
