const Axios = require('axios')

async function downloadImage () {
const url = 'https://unsplash.com/photos/AaEQmoufHLk/download?force=true'
const path = Path.resolve(__dirname, 'images', 'code.jpg')
const writer = Fs.createWriteStream(path)

const response = await Axios({
url,
method: 'GET',
responseType: 'stream'
})

response.data.pipe(writer)

return new Promise((resolve, reject) => {
writer.on('finish', resolve)
writer.on('error', reject)
})
}

downloadImage()

主要注意的是

  • responseType: 'stream'
  • response.data.pipe(writer)
