Question

有可能吗？我上传图片后没有权限。我认为应该将ACL: 'public-read'放在数据中。这是我的代码：

var data = {ACL: 'public-read', Bucket: 's3.bucket', Key: 'latest.png', Body: result.Body, ContentLength: result.ContentLength};

s3.putObject(data, function(err, output_data) {
   if (err) {
              console.log('Error uploading data: ', err); 
            }
            else {
             console.log('succesfully uploaded the image!');
            }
  });

但是我收到了这个错误：

存储桶本身具有所有权限。

Answer 1

您的错误显示region：null。 S3具有唯一的全局端点，但它会将您的数据保存在某个特定位置，并且您必须在将内容上载到s3存储桶时提供区域。

在S3中的lambda函数中上传图像后更改图像的权限
