节点js中的AWS SDK javascript返回拒绝访问

伙计们，当我试着列出我所有的桶时，它就像预期的那样工作。因此，我可以确保我的设置是正确的。 问题是当我尝试列出一个bucket的内容时：

我在节点js中有一个路由

/：bucket

app.get('/:bucket', function (req, res) {
    var bucket = req.params.bucket;
    var s3 = new AWS.S3();
    var params = {
        Bucket: 'bucket'
    };
    s3.listObjects(params, function (err, data) {
        if (err)
            console.log(err, err.stack); // an error occurred
        else
            console.log(data);           // successful response
    });
});

这不起作用，返回访问被拒绝

以下是bucket策略：

{
  "Id": "Policy...............",
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid": "Stmt..........",
      "Action": "s3:*",
      "Effect": "Allow",
      "Resource": "arn:aws:s3:::my_bucket/*",
      "Principal": "*"
    }
  ]
}

这就是我得到的错误：

您提供了正确的凭据吗？在.aws/config中是的。当尝试列出与我的帐户关联的所有存储桶时，它会返回它们。您确定您请求存储桶的方式正确吗。您有一个字符串

“bucket”

而不是变量

bucket

此处：

存储桶：“bucket”

另一个可能是的东西，您想知道吗在

我的桶下显示桶

？哦，太糟糕了。你说得对。我回去工作时会试试这个，我会让你知道它是否有效。
