使用node.js服务器上传到亚马逊s3仅有效一次
使用node.js服务器上传到亚马逊s3仅有效一次
提问于 2018-06-11 06:33:02
下面是我用来将图像上传到服务器的代码，但它只起作用一次
接受答案的注释中的答案
- 我根本不知道是否应该设置端点，s3教程中的所有示例都没有提到端点
- 我不确定是否应该继续为每个文件创建新的s3对象以上传
- 如果不设置端点，即使第一次尝试，上传也总是失败(并给出与下面发布的第二次上传相同的控制台输出)
upload函数只工作一次，所以我认为这意味着我正确地设置了凭证。但让它再次运行的唯一方法是重启node.js应用程序。我很确定我错过了很多东西。我特别注意到，在第二次上传时，s3对象希望连接到本地主机，而不是我在创建时为其显式设置的端点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);
}
});
下面是第一次和后续上传尝试的控制台输出：

在第二次上传期间，它似乎试图在localhost域中查找您的存储桶。您可以尝试指定区域而不是端点吗？
无论采用哪种方式，S3服务对象都应该将该信息提供给端点。

我也遇到过类似的问题，这个配置适用于我。
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"
