我正在尝试使用Amazon S3设置简单的JS图像上传。以下是我的代码。
JS :
host = "https://s3.eu-central-1.amazonaws.com/my.bucket.url/";
uploadAttachment = function(attachment) {
file = attachment.file;
key = createStorageKey(file);
form = new FormData;
form.append("key", key);
form.append("acl", "public-read");
form.append("Content-Type", file.type);
form.append("file", file);
xhr = new XMLHttpRequest;
xhr.open("PUT", host + key, true);
// ...
xhr.send(form);
};
createStorageKey = function(file) {
var date, day, time;
date = new Date;
day = date.toISOString().slice(0, 10);
time = date.getTime();
return "s3/attachments/" + day + "/" + time + "-" + file.name;
};
S3 Bucket Policy :
{
"Version": "2008-10-17",
"Statement": [
{
"Sid": "1",
"Effect": "Allow",
"Principal": "*",
"Action": "s3:*",
"Resource": "arn:aws:s3:::my.bucket.url/*"
}
]
}
S3 CORS :
<?xml version="1.0" encoding="UTF-8"?>
<CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
<CORSRule>
<AllowedOrigin>*</AllowedOrigin>
<AllowedMethod>GET</AllowedMethod>
<AllowedMethod>PUT</AllowedMethod>
<MaxAgeSeconds>3000</MaxAgeSeconds>
<AllowedHeader>*</AllowedHeader>
</CORSRule>
</CORSConfiguration>
一切正常,但上传的文件不公开。而且,我甚至无法从Web界面公开它们。我唯一能做的就是删除它们。我真的需要公开这些文件。
如果可能,我真的想在不使用任何访问密钥的情况下完成此任务。
非常感谢任何帮助!

我明白了。
<强> JS 强>:
host
更改为my.bucket.s3.eu-central-1.amazonaws.com
。xhr.open("POST", host, true)
。acl
参数。<强> CORS:强>
