使用nodejs将所有图片保存到S3后，如何获取url？

npm install aws-sdk

const AWS = require('aws-sdk');

const s3 = new AWS.S3({
  accessKeyId: 'YOUR_ACCESS_KEY',
  secretAccessKey: 'YOUR_SECRET_ACCESS_KEY',
  region: 'YOUR_REGION'
});

const params = {
  Bucket: 'YOUR_BUCKET_NAME',
  Key: 'YOUR_IMAGE_KEY',
  Body: 'YOUR_IMAGE_DATA',
  ContentType: 'image/jpeg' // 根据实际情况设置正确的Content-Type
};

s3.putObject(params, (err, data) => {
  if (err) {
    console.error(err);
  } else {
    console.log('Image uploaded successfully');
    // 在这里获取图片的URL
  }
});

const urlParams = {
  Bucket: 'YOUR_BUCKET_NAME',
  Key: 'YOUR_IMAGE_KEY',
  Expires: 3600 // URL的有效期，单位为秒
};

const imageUrl = s3.getSignedUrl('getObject', urlParams);
console.log('Image URL:', imageUrl);
