Question

所以这是我用来将图像上传到服务器的代码，但它只能运行一次

[在接受的答案的评论中回答]

我不知道我是否应该设置端点，s3教程中的所有示例都没有提到端点
我不确定我是否应该为每个要上传的文件制作新的s3对象
如果我没有设置端点，即使第一次尝试上传也总是失败（并提供与下面发布的第二次上传相同的控制台输出）

上传功能只运行一次，所以我认为这意味着我正确设置了凭据。但让它再次运行的唯一方法是重新启动node.js应用程序。我很确定我错过了很多东西。特别是我注意到在第二次上传时，s3对象想要连接到localhost，而不是我在制作时为其明确设置的端点url。

function upload_photo(socket, data) {
	s3 = new AWS.S3( {endpoint: 'http://s3-ap-southeast-1.amazonaws.com'} );
	
	console.log("s3 endpoint", s3.endpoint); // for testing

	var myBucket = 'blackjack-profilepics';	
	var myKey = socket.player.user_id +".txt";

	params = {Bucket: 'blackjack-profilepics', Key: myKey, Body: data };
	s3.putObject(params, function(err, data) {
	if (err) {
		console.log("Error uploading data:",err)
		console.log("s3 endpoint", s3.endpoint);
	} else {
		console.log("Successfully uploaded data to myBucket/%s", myKey);
	}
  });

这是第一次和后续上传尝试的控制台输出：

Answer 1

在第二次上传期间，它似乎正在尝试在localhost域上查找您的存储桶。您可以尝试指定区域而不是端点吗？

S3服务对象应该以任何方式将该信息提供给端点。

s3 = new AWS.S3({region: 'ap-southeast-1'})

Answer 2

我遇到了类似的问题，此配置对我有用。

const bucketname = 'bsbucket';
//configuring the aws environment
aws.config.update({
    region:"us-west-1",
    accessKeyId:"<accessKeyId>",
    secretAccessKey:"<secretAccessKey>",
    s3BucketEndpoint:true,
    endpoint:"http://" + bucketname + ".s3.amazonaws.com"
});

使用node.js服务器上传到amazon s3只能运行一次
