为什么通过 URL 上传到 S3 的文件没有扩展名？

发布于 2024-11-27 01:34:24 字数 995 浏览 0 评论 0原文

我在 Heroku 上使用 s3 上传图片没有问题。

我还有一种方法可以让用户从网址上传。

不幸的是，似乎当使用这种方法上传图片时，它们保存时没有文件扩展名。

所以我得到了这种图像网址的链接......

http://s3.amazonaws.com/mysite/images/23 /原.?1311799466

如果相同的图像已上传到本地，它将如下所示：

http://s3.amazonaws.com/mysite/images/23/original< /a>.JPG?1311799466

在我的 pic 模型中，这是我用来允许通过网址上传的代码：

def download_remote_image

        begin
            self.image = open(URI.parse(self.pic_url))
        rescue
            errors.add_to_base("- something is wrong with the image url.")
            return false
        else
            return true
        end
    end

有什么想法吗？

I've got picture uploads working with s3 on heroku no problem.

I also have a method that enables users to upload from a web-address.

Unfortunately, it seems as though when pictures are uploaded using this method they are saved without their file extension.

So I get this sort of link for image urls...

http://s3.amazonaws.com/mysite/images/23/original.?1311799466

If the same image had been uploaded locally it would look like this:

http://s3.amazonaws.com/mysite/images/23/original.JPG?1311799466

In my pic model this is the code I'm using to allow uploads via web addresses:

def download_remote_image

        begin
            self.image = open(URI.parse(self.pic_url))
        rescue
            errors.add_to_base("- something is wrong with the image url.")
            return false
        else
            return true
        end
    end

Any ideas?

对此进行更改：

def download_remote_image
  begin
    io = open(URI.parse(pic_url))
    def io.original_filename; base_uri.path.split('/').last; end
    io.original_filename.blank? ? nil : io
  rescue
  end
end

小心，最新版本的 Paperclip 在遇到 io 对象而不是 File 时会抛出错误，不确定他们是否修复了该问题。

Change with this:

def download_remote_image
  begin
    io = open(URI.parse(pic_url))
    def io.original_filename; base_uri.path.split('/').last; end
    io.original_filename.blank? ? nil : io
  rescue
  end
end

Careful, recent versions of Paperclip throw errors when encountering a io object instead of File, not sure if they fixed that.
