Question

我正在尝试通过亚马逊以卷曲方式从Heroku中提取数据库备份，并且我一直在获取空文件。交易的基本形式是：

 curl -o latest-dump `heroku pgbackups:url`

当然，后面的滴答是将其作为动态插入长URL的命令运行。我放弃了在CMD中这样做，并试图在cygwin中这样做，因为至少它理解后面的滴答声。

我可以在我的个人Mac上成功运行此命令，因此我很难理解为什么它无法按预期提供文件。

当我使用verbose选项运行curl命令时，唯一的指示是400 Bad Request，这让我觉得heroku命令的输出被破坏了。所以我复制了heroku命令的输出并尝试了它：

 curl -v -o latest.dump 'https://s3.amazonaws.com/hkpgbackups/app28197640@heroku.com/xxxx.dump?AWSAccessKeyId=AKIAJSCBEZJRDOTGNGZQ&Expires=1410954117&Signature=pOgPFgADIvrWT%2FfBT6MXQFxhWhc%3D'

它的输出低于但我没有看到错误？

这个网址有什么特别的东西在这里打扰我吗？它确实似乎改变了它的签名？帮助我看看我在这里缺少的东西，感谢，山姆

Answer 1

这应该按原样运行，但是一位朋友查看了它，发现该URL由heroku.bat程序提供。由于Heroku URL非常长，Windows端不断在URL中添加回车符。我会从亚马逊那里得到400个错误。大概如果它是heroku.sh它应该没有修改但是现在可以在cygwin中运行：

curl -o latest.dump -l＆＃34; $（heroku.bat pgbackups：url | dos2unix）＆＃34;

感谢Naaman Newbold没有放弃这个问题。

Answer 2

我有同样的问题。我在Google Chrome中按原样粘贴了网址，并为我下载了该文件。
