用nodejs下载一张图片

分别使用流式和arraybuffer两种方式下载成功, 个人偏爱arraybuffer

流式下载

const axios = require('axios')
const fs = require('fs')

let url = 'https://gss0.baidu.com/94o3dSag_xI4khGko9WTAnF6hhy/zhidao/pic/item/314e251f95cad1c83f06dc11733e6709c93d5142.jpg'
axios({
  url,
  responseType: 'stream'
}).then(
  (resp) => {
    const writer = fs.createWriteStream('./t2.jpg')
    resp.data.pipe(writer)
    writer.on('finish', () => {
      console.log('finish')
    })
    writer.on('error', () => {
      console.log('error')
    })
  }
)

arraybuffer

const axios = require('axios')
const fs = require('fs')

let url = 'https://gss0.baidu.com/94o3dSag_xI4khGko9WTAnF6hhy/zhidao/pic/item/314e251f95cad1c83f06dc11733e6709c93d5142.jpg'
axios({
  url,
  responseType: 'arraybuffer'
}).then(
  ({data}) => {
    fs.writeFileSync('./t.jpg', data, 'binary')
  }
)
