这是在最新版本的aws-sdk上使用流传输的完整代码
var express = require('express');var app = express();var fs = require('fs');app.get('/', function(req, res, next){ res.send('You did not say the magic word');});app.get('/s3Proxy', function(req, res, next){ // download the file via aws s3 here var fileKey = req.query['fileKey']; console.log('Trying to download file', fileKey); var AWS = require('aws-sdk'); AWS.config.update( { accessKeyId: "....", secretAccessKey: "...", region: 'ap-southeast-1' } ); var s3 = new AWS.S3(); var options = { Bucket : '/bucket-url', Key : fileKey, }; res.attachment(fileKey); var fileStream = s3.getObject(options).createReadStream(); fileStream.pipe(res);});var server = app.listen(3000, function () { var host = server.address().address; var port = server.address().port; console.log('S3 Proxy app listening at http://%s:%s', host, port);});
