我试图上传图片到s3与预先签署的网址从aws sdk生成。

router.get('/upload-url', async(req, res) => {
    try {

        AWS.config.update({
            secretAccessKey: process.env.AWS_SECRET_ACCESS,
            accessKeyId: process.env.AWS_ACCESS_KEY,
            region: 'ap-southeast-1'

        });

        const s3 = new AWS.S3();
        var params = { Bucket: process.env.bucket_name, Key: 'products', ContentType: 'image/jpeg' };
        s3.getSignedUrl('putObject', params, function(err, url) {
            if (err) {
                throw (err)
            }
            res.status(200).send({ link: url })
        })

    } catch (err) {
        res.status(400).send({ message: err.message })
    }
})

字符串
与上面的返回网址，它给给予一个错误，当我试图访问它

我一直在寻找其他职位，但还没有找到解决方案。
我发现的一些建议是：

• 不要在SECRET ACCESS KEY中包含“/”。（我的密钥不包含斜杠）
• 不正确的凭据（我已经测试了与AWS的密钥，它的作品）
• 更新存储桶权限和策略。（我已更新到所有访问策略）

我的bucket设置如下：
Bucket policy

{
    "Version": "2012-10-17",
    "Id": "Policy1594951813323",
    "Statement": [
        {
            "Sid": "Stmt15949510950",
            "Effect": "Allow",
            "Principal": {
                "AWS": "arn:aws:iam::<AccountNumber>:root"
            },
            "Action": "s3:*",
            "Resource": "arn:aws:s3:::<bucketname>/*"
        }
    ]
}

Use PUT Instead of POST for the pre-sign url to upload file to S3
