使用Axios/Sharp下载图像并调整图像大小

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

async function downloadAndResizeImage(url, outputPath, width, height) {
  try {
    // 使用 Axios 下载图像
    const response = await axios({
      method: 'GET',
      url: url,
      responseType: 'stream',
    });

    // 使用 Sharp 调整图像大小并保存
    const transformer = sharp()
      .resize(width, height)
      .toBuffer();

    const writer = fs.createWriteStream(outputPath);

    response.data.pipe(transformer).pipe(writer);

    return new Promise((resolve, reject) => {
      writer.on('finish', resolve);
      writer.on('error', reject);
    });
  } catch (error) {
    console.error('Error:', error);
  }
}

// 示例调用
downloadAndResizeImage(
  'https://example.com/image.jpg',
  'output/resized-image.jpg',
  300,
  200
).then(() => {
  console.log('Image downloaded and resized successfully!');
}).catch((error) => {
  console.error('Failed to download and resize image:', error);
});
