javascript - Node 获取连接 ETIMEDOUT 错误

Question

我正在尝试获取 200 状态代码作为响应，但结果是 ETIMEDOUT。我不明白，我怎么可能通过 postman 获取成功的响应，但同样通过 node-fetch 始终以 ETIMEDOUT 响应。这是一个代码示例:

const Resource = {
  get: cb => {
    fetch('https://example.com', {
      method: 'POST',
      headers: {'Content-Type': 'application/x-www-form-urlencoded'},
      body: {...some body...},
    }).then(res => {
      if (res.status !== 200) cb(`Status: ${res.status}, ${res.statusText}`)
      return res.text()
    }).then(data => {
        cb(null, data)
      }).catch((err) => {
       console.log('ERROR: ', err)
      })
  }
}

这是回应:

ERROR: { FetchError: request to https://example.com failed, reason: connect ETIMEDOUT

看起来是因为代理限制。
