我从Amazon SDK传递给getSignedUrl的参数是什么关键

Im generating a pre-signed url so i can upload a file to a S3 bucket.

我生成一个预先签名的URL,以便我可以将文件上传到S3存储桶。

var params = {Bucket: 'xxxxxxx', Key: 'key', Expires: 60};
var url = s3.getSignedUrl('putObject', params);
console.log('The URL is', url);

The Key parameter is required, but i cant find in the documentation how can i generate this.

Key参数是必需的,但我无法在文档中找到如何生成它。

If i submit an upload using this generated URL:

如果我使用此生成的URL提交上传:

xhr.open("PUT", url);
xhr.setRequestHeader('Content-Type', files[0].type);
xhr.setRequestHeader('x-amz-acl', 'authenticated-read');
xhr.send(files[0]);

It returns this error SignatureDoesNotMatch

它返回此错误SignatureDoesNotMatch

Am i missing something on the url signing method?

我错过了网址签名方法的内容吗?

Just figured this out. Parameters to sign URL must have all the things that im sending on the header and the Key is the file name.

刚想通了。签名URL的参数必须包含我在标题上发送的所有内容,而Key是文件名。

var params = {Bucket: 'xxxxxxx', Key: 'filename.ext', Expires: 60, ACL:'authenticated-read', ContentType: 'applicattion/xxxxx'};

This fixed my problem.

这解决了我的问题。
