如何在Base64中用Node.js，lambda函数压缩图像

npm install sharp

const sharp = require('sharp');

// 读取原始图像文件
sharp('input.jpg')
  // 调整图像大小
  .resize(800, 600)
  // 压缩图像质量
  .jpeg({ quality: 80 })
  // 将图像转换为Base64编码
  .toBuffer((err, data, info) => {
    if (err) {
      console.error(err);
    } else {
      const base64Image = data.toString('base64');
      console.log(base64Image);
    }
  });

const sharp = require('sharp');

exports.handler = async (event) => {
  const { image } = event;

  try {
    const compressedImage = await sharp(image)
      .resize(800, 600)
      .jpeg({ quality: 80 })
      .toBuffer();

    const base64Image = compressedImage.toString('base64');

    return {
      statusCode: 200,
      body: base64Image,
    };
  } catch (error) {
    console.error(error);

    return {
      statusCode: 500,
      body: 'Image compression failed.',
    };
  }
};
