使用image-to-base64把在线的图片链接转换成base64,可用于claude3识图

const imageToBase64 = require('image-to-base64')

const handleImageToBase64 = async ({ visionImgList }) => {
  const order = async ({ visionImgList }) => {
    //item.url 示例：'https://static.xutongbao.top/ai/wx/290289803149-3731757233684041524.jpg'
    const promises = visionImgList.map(async (item) => {
      return await imageToBase64(item.url).catch((error) => {
        console.log(error) // Logs an error if there was one
      })
    })
    let visionImgListTemp = []
    for (let i = 0; i < promises.length; i++) {
      let base64Str = await promises[i]
      let imgUrl = visionImgList[i].url.toLowerCase()
      visionImgList[i].url.toLowerCase().includes('jpg')
      let media_type = ''
      if (imgUrl.includes('.jpg')) {
        media_type = 'image/jpeg'
      } else if (imgUrl.includes('.jpeg')) {
        media_type = 'image/jpeg'
      } else if (imgUrl.includes('.png')) {
        media_type = 'image/png'
      } else if (imgUrl.includes('.webp')) {
        media_type = 'image/webp'
      }

      visionImgListTemp.push({
        type: 'image',
        source: {
          type: 'base64',
          media_type, //'image/jpeg', 'image/png', 'image/gif' or 'image/webp'
          data: base64Str,
        },
      })
    }
    return visionImgListTemp
  }
  let visionImgListTemp = await order({ visionImgList })

  return visionImgListTemp
}

最简demo

const imageToBase64 = require('image-to-base64')

if (type === 'image-to-base64') {
    let response = await imageToBase64(
      'https://static.xutongbao.top/ai/wx/290289803149-3731757233684041524.jpg'
    ).catch((error) => {
      console.log(error) // Logs an error if there was one
    })
    res.send({
      code: 200,
      data: {
        response,
      },
      message: '成功',
    })
  }
