如何在nodejs中将Base64字符串解码并作为图片上传到亚马逊s3？

npm install aws-sdk
npm install fs
npm install path

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

AWS.config.update({
  accessKeyId: 'YOUR_ACCESS_KEY',
  secretAccessKey: 'YOUR_SECRET_ACCESS_KEY',
  region: 'YOUR_REGION'
});

const s3 = new AWS.S3();

const base64Data = 'YOUR_BASE64_STRING';
const decodedImage = Buffer.from(base64Data, 'base64');

const fileName = 'image.jpg'; // 可以根据需要修改文件名

const uploadParams = {
  Bucket: 'YOUR_BUCKET_NAME',
  Key: fileName,
  Body: decodedImage,
  ACL: 'public-read' // 可以根据需要修改访问权限
};

s3.upload(uploadParams, (err, data) => {
  if (err) {
    console.error('Error uploading image:', err);
  } else {
    console.log('Image uploaded successfully:', data.Location);
  }
});
