无法从 linux 终端获取文件

Unable to wget the file from linux terminal

我正在尝试从 S3 存储桶下载文件。 URL 的 link 是预签名的 url。我可以通过网络浏览器下载 S3 link，但不幸的是它不适用于 linux 终端。下面是示例 link.

这是我在 wget 之后得到的响应

有没有其他方法可以从终端下载上述 URL？

您需要引用url。也就是说，而不是：

wget URL

你需要：

wget 'URL'

URL 包含对 shell 具有特殊含义的字符，例如 &。这是下载失败 URL 和您看到的所有后续错误的根源。

我可以从预签名的 S3 下载对象 url。通过以下命令为我解决了问题。

wget -O text.zip "https://presigned-s3-url"

解压缩后 text.zip，我可以看到我的文件。
