是的，绝对有可能！
var AWS = require('aws-sdk');
function putObjectToS3(bucket, key, data){
var s3 = new AWS.S3();
var params = {
Bucket : bucket,
Key : key,
Body : data
}
s3.putObject(params, function(err, data) {
if (err) console.log(err, err.stack); // an error occurred
else console.log(data); // successful response
});
}
通过选择或更新执行lambda的IAM角色，确保为Lambda函数提供对目标s3存储桶/密钥路径的必需写权限。
