S3 :: Error :: SignatureDoesNotMatch：当我尝试保存新对象时

Question

这是我的保存文件，不是我尝试登录时出现的文件。这是我的代码：

service = S3::Service.new(
    :access_key_id     => S3_ACCESS_KEY,
    :secret_access_key => S3_SECRET
  )
puts "connection established with s3"

puts "finding bucket"
bucket = service.buckets.find("")
puts "building object"
object = bucket.objects.build("#{RAILS_ROOT}/jsonexport/ema.txt")
puts "saving object"
object.content = open("#{RAILS_ROOT}/export/ema.txt")
object.save

我可以在控制台中运行所有这些代码，直到到达object.save为止，然后引发此错误：

S3::Error::SignatureDoesNotMatch: The request signature we calculated does not match the signature you provided. Check your key and signing method.

有人有任何建议或想法吗？

好吧...这行得通。

    service = S3::Service.new(
    :access_key_id     => S3_ACCESS_KEY,
    :secret_access_key => S3_SECRET
  )
puts "connection established with s3"

puts "finding bucket"
bucket = service.buckets.find("euro")

puts "building ema"
object = bucket.objects.build("jsonexport/ema.json")
puts "saving ema"
object.content = open("jsonexport/ema.json")
object.save
