轨道载波/ S3签名不匹配。私钥错误

Question

我正在尝试使载波与S3一起工作，而我得到的签名则无法匹配错误。奇怪的是，看起来CarrierWave并没有发送正确的秘密键。在错误中，该帖子以：

给出。

"Authorization"=>"AWS AKIAIOLWQKSJFH6E3I5Q:vKgyAw2z4c8zzqGWoxLUbw7I5oI="

我认为应该是我的publickey：私人关键。问题是vkgyaw2z4c8zzqgwoxlubw7i5oi =不是我存储在fog.rb中的私钥。是对的吗？

任何帮助将不胜感激。

Answer 1

我设法修复了此问题。我不确定自己做了什么，但是有几个问题。（1）我认为我正在遇到验证错误，因为我在上传器中指定了一个文件夹。现在，我将Uploader中的目录设置为"并通过FOG配置指定文件夹。

（2）我遇到的另一个错误是时间不匹配。我在虚拟机中运行薄荷以进行开发，时间与现实不同。亚马逊对此提出了错误。一旦我设置了正确的时间，那就消失了。
