Question

在调用getObject时，似乎无法找到指定对象位置的位置。

基本上，尝试从s3获取对象并下载它。我能够获得没有问题的对象，但它没有下载它。我错过了一个参数吗？

// Load the SDK and UUID
var AWS = require('aws-sdk');
var uuid = require('node-uuid');

// Create an S3 client
var s3 = new AWS.S3();

var params = {
Bucket: "my-artifacts",
Key: "artifact.jar"
};
s3.getObject(params, function(err, data) {
if (err) console.log(err, err.stack); // an error occurred
else     console.log(data);           // successful response
});

所以看起来它是用节点使用流来创建的，这看起来比我找到的其他答案简单得多：

// Load the SDK
var AWS = require('aws-sdk');
var fs = require('fs');

var s3 = new AWS.S3({apiVersion: '2006-03-01'});
var params = {
Bucket: "your-bucket",
Key: "your/dir/location/for/object.war",
};
var file = require('fs').createWriteStream('yourlocaldirectory/object.war');
s3.getObject(params).createReadStream().pipe(file);

在此处找到：http://docs.aws.amazon.com/sdk-for-javascript/v2/developer-guide/requests-using-stream-objects.html

使用节点v8.1.3

使用aws-sdk从s3获取getObject并在本地存储
