Answer 1

我认为您正在寻找的是

  users: [
    {
      name: 'foo',
      forwhom: 0,
      signatures: {
        clientSignature: {
          value: ''
        }
      }
    },
    {
      name: 'bar',
      forwhom: 1,
      signatures: {
        clientSignature: {
          value: ''
        }
      }
    }
  ]

这将返回您在第一个捕获组中所需的内容。
