如何添加自定义标头以logstash http poller输入？

Question

我正在尝试使用logstash来轮询Uber API（仅作为示例）以从API获取数据并且（此时）仅输出到控制台。似乎无法使自定义标头工作：

input {
  http_poller {
    urls => {
      test2 => {
        # Supports all options supported by ruby's Manticore HTTP client
        method => get
     url => "https://api.uber.com/v1/products?latitude=37.7759792&longitude=-122.41823"
                headers => {
                Authorization => "P8YegbF53nWPZST5xX0ZlktVnufXYYQa01Dy0ocm"
                }
      }
    }
    request_timeout => 60
    interval => 60
    codec => "json"
    # A hash of request metadata info (timing, response headers, etc.) will be sent here
    metadata_target => "http_poller_metadata"
  }
}


output {
    stdout {}
}

如果我理解这个概念，那应该是放置标题的地方，但由于它不是基本的auth，我不能在样本中使用Auth标志。
