node.js - Using Node.js to create bucket and push object, extra blank file created?

Question

I'm using an ExpressJS (based on Node.js) to push up to Amazon S3. I'm new to this so, I copied the example Amazon gave, and I see that in the S3 Management Console, there's an extra file that's the same name as the bucket I'm creating. What part of my code made this?

// Create a bucket using bound parameters and put something in it.
var s3bucket = new AWS.S3({params: {Bucket: 'test_bucket/sub_bucket'}});
s3bucket.createBucket(function() {
    var data = {Key: 'result', Body: 'Hello!'};
    s3bucket.putObject(data, function(err, data) {
        if (err) {
            console.log("Error uploading data: ", err);
        } else {
            res.writeHead(200, {'Content-Type':'text/plain'});
            res.write("Successfully uploaded data to test_bucket/sub_bucket/");
            res.end()
        }
    });
});

Answer 1

var s3bucket = new AWS.S3({params: {Bucket: 'test_bucket/sub_bucket'}});将创建一个额外的文件。取出括号中的参数。我发现亚马逊的快速入门指南示例创建了一个额外的文件。这种方式是正确的做法。

// Create a bucket using bound parameters and put something in it.
var s3bucket = new AWS.S3();
s3bucket.createBucket(function() {
    var params = {Bucket: 'bucket/sub-bucket', Key: 'file_name1', Body: 'Hello!'};
    s3bucket.putObject(params, function(err, data) {
        if (err) {
            console.log("Error uploading data: ", err);
        } else {
            res.writeHead(200, {'Content-Type':'text/plain'});
            res.write("Successfully uploaded data to bucket/sub-bucket/");
            res.end()
        }
    });
});
