如何在 node.js 中提取 http 响应

Question

从http get 请求获取响应时，响应对象包含许多不同的字段。例如，如果我想从 __writableState 中提取 highWaterMark 值，我应该怎么做呢？

_writableState: 
      { highWaterMark: 16384,
        objectMode: false,
        needDrain: false,
        ending: false,
        ended: false,
        finished: false,
        decodeStrings: true,
        defaultEncoding: 'utf8',
        length: 0,
        writing: false,
        sync: false,
        bufferProcessing: false,
        onwrite: [Function],
        writecb: null,
        writelen: 0,
        buffer: [],
        errorEmitted: false },
