从heroku上的应用程序上传文件到s3时,我得到看似随机的erorrs。我正在使用jquery-file-upload将图片上传到我的桶中的tmp /目录,使用CORS方法和此代码。Intermittent Carrierwave S3 403签名不匹配错误
def url
temp_url = AWS::S3::S3Object.url_for(
s3_key,
S3_CONFIG['bucket'],
use_ssl: true)
puts temp_url
temp_url
# temp_url.to_s.encode_signs
end
def delete_photo_from_s3
begin
photo = AWS::S3::S3Object.find(s3_key, S3_CONFIG['bucket'])
photo.delete
rescue Exception => e
Rails.logger.error e.message
end
end
private
def s3_key
parent_url = self[:uri]
# If the url is nil, there's no need to look in the bucket for it
return nil if parent_url.nil?
# This will give you the last part of the URL, the 'key' params you need
# but it's URL encoded, so you'll need to decode it
object_key = parent_url.split(/\//)
"#{object_key[3]}/#{object_key[4]}/#{object_key[5]}"
end
从那里我使用carrierwave上传和处理这些图像。但是,有时上传会失败,我的s3存储桶中出现403 Forbidden错误。不知道是什么原因造成的。
从那里,我使用Qu处理后台作业,使用remote__url调用将图像附加到carrierwave。这是我的后台任务:
class PhotoUploader
def self.perform(finding_id, photo_id)
begin
finding = Finding.find(finding_id)
photo = Photo.find(photo_id)
upload = finding.uploads.build
# attached_picture = photo.temp_image_url || photo.url
upload.remote_attachment_url = photo.url
if upload.save!
Rails.logger.debug "#{Time.now}: Photo #{photo_id} saved to finding..."
photo.set(:delete_at => 1.hour.from_now) # UTC, same as GMT (Not local time!)
photos = Photo.where(:processing => true, :delete_at.lte => Time.now.utc) # Query for UTC time, same type as previous line (also not local time!)
finding.unset(:temp_image)
if photos
photos.each do |photo|
photo.destroy
Rails.logger.debug "Photo #{photo.id} - #{photo.uri} destroyed."
end
end
else
raise "Could not save to s3!"
end
rescue Exception => e
Rails.logger.debug "#{Time.now}: PH01 - Error processing photo #{photo_id}, trying again... :: #{e.message}"
retry
end
end
end
这有时候,但并不总是,这真的很奇怪。 我最终得到了一堆这样的错误在我的S3日志:

我已经阅读了很多关于这方面的内容,看起来人们有时会在签名中出现非转义'+'的时候出现这个问题。我不确定这是Carrierwave,Fog还是AWS :: S3问题。
如果您可以提供任何援助,这将不胜感激。
谢谢。
得到了同样的问题。你有没有找到解决办法? – damienbrz
我找到了解决方法。首先,确保你的服务器的系统时间准确无误。这可能会导致AWS的“时间偏差”错误。然后将此添加到您的载波上传器 'def process_uri(uri) URI。解析(uri) 结束' 这将覆盖默认的carrierwave url解析器,我认为这是解析器。 你可以在这里阅读更多关于这个问题https://github.com/carrierwaveuploader/carrierwave/issues/700 – Bramanga
