问节点-获取连接ETIMEDOUT错误

EN

我试图得到200个状态代码作为响应，但结果是ETIMEDOUT。我不明白，我怎么可能通过postman获得成功的响应，但是通过节点获取响应的方式是一样的--总是使用ETIMEDOUT获取响应。下面是一个代码示例：

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)
      })
  }
}

以下是回应：
