nodejs s3存储桶上传脚本可重用

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

// 配置AWS凭证和S3存储桶信息
const credentials = new AWS.SharedIniFileCredentials({ profile: 'default' });
AWS.config.credentials = credentials;
AWS.config.update({ region: 'us-west-2' });

// 创建S3对象
const s3 = new AWS.S3();

// 上传文件到S3存储桶
function uploadFileToS3(bucketName, fileName, filePath) {
  const fileContent = fs.readFileSync(filePath);

  const params = {
    Bucket: bucketName,
    Key: fileName,
    Body: fileContent
  };

  s3.upload(params, (err, data) => {
    if (err) {
      console.error('上传失败：', err);
    } else {
      console.log('上传成功：', data.Location);
    }
  });
}

// 使用示例
const bucketName = 'my-bucket';
const fileName = 'example.txt';
const filePath = '/path/to/example.txt';

uploadFileToS3(bucketName, fileName, filePath);
