Heroku S3 回形针不起作用

【问题标题】：Heroku S3 Paperclip Doesn't workHeroku S3 回形针不起作用

【问题描述】：

我在使用回形针和 heroku 时遇到问题，真的需要帮助。过去 2 天我一直被困在这个问题上，我找不到的链接都没有帮助：

https://github.com/igor-alexandrov/paperclip-aws"
"http://www.codeitive.com/0QHVXqkUVV/heroku-paperclip-s3-error-%3E-    awss3errorssignaturedoesnotmatch.html"
"https://devcenter.heroku.com/articles/paperclip-s3#international-users-additional-configuration"
"http://dchua.com/2011/12/27/how-to-get-paperclip-and-aws-s3-singapore-and-european-buckets-working/"

"http://stackoverflow.com/questions/7257745/rails-3-amazon-s3-paperclip-eu-problem"

一开始我想使用欧洲 S3 位置，但由于它似乎让一切变得更加复杂，我决定切换回默认的美国位置。

我在终端上设置了我的 VARS：

$ heroku config:set S3_BUCKET_NAME=your_bucket_name
$ heroku config:set AWS_ACCESS_KEY_ID=your_access_key_id
$ heroku config:set AWS_SECRET_ACCESS_KEY=your_secret_access_key

然后在我的 config/environment/production.rb 中：

config.paperclip_defaults = {
  :storage => :s3,
  :s3_credentials => {
    :bucket => ENV['S3_BUCKET_NAME'],
    :access_key_id => ENV['AWS_ACCESS_KEY_ID'],
    :secret_access_key => ENV['AWS_SECRET_ACCESS_KEY']
  }
}

访问我的网站并尝试上传图片时，我的 heroku 日志如下：

显然我已经仔细检查了我的 heroku 配置并尝试再次输入密钥和存储桶 => 没有变化。

在这一点上，我尝试了很多东西，以至于我迷路了。 在 attach_files 之后在我的模型中设置 heroku 的东西 除了 heroku config var 之外，还设置 heroku YAML 文件 尝试了欧洲和美国标准水桶

如果有人有任何想法.. 我对该错误所做的所有研究都没有帮助：AWS::S3::Errors::SignatureDoesNotMatch: The request signature we calculated does not match the signature you provided. Check your key and signing method.

【问题讨论】：

  • 它在本地工作吗？您使用的是哪个版本的回形针？我知道你说过你仔细检查了你的heroku config，但再次检查你没有交换你的访问密钥 ID 和密钥...... :)
  • 我没有在本地尝试过。我认为它会更简单。我现在正在这样做并且“缺少必需的：bucket 选项”我想这是需要研究的东西。很奇怪，我在尝试解决我的问题时在 stackoverflow 上一次又一次地看到该错误，但我第一次看到它。我怀疑它来自我的本地配置，而不是与其他错误有关。
  • 好吧，去本地工作吧
  • 好，现在可以直播了
  • 是的，它正在现场工作。但这与 heroku 回形针教程所说的相去甚远。

【解决方案1】：

好吧，让它继续工作，以便下一个人遇到这个问题：

-不要遵循heroku回形针教程

-在您的配置文件夹中创建一个 aws.yml 文件：

development:
  access_key_id: "xxxxxinquote"
  secret_access_key: "yyyyyinquote"
test:
  access_key_id: abc...
  secret_access_key: abc...
production:
  access_key_id: "xxx"
  secret_access_key: "yyyy"

-在所有带有文件上传的模型中放置：

has_attached_file :image,
                  :styles => { :medium => "460x>", :thumb => "100x100>",:vnice=> "400x" },
                  :storage => :s3,
                  :bucket => 'hohohohoho',
                  :s3_credentials => "#{Rails.root}/config/aws.yml",
                  :path => "resources/:id/:style/:basename.:extension

然后在您的生产或/和 dev.rb 中

config.paperclip_defaults = {
  :storage => :s3,
    :bucket => ENV['S3_BUCKET_NAME'],
  :s3_credentials => {
    :access_key_id => ENV['AWS_ACCESS_KEY_ID'],
    :secret_access_key => ENV['AWS_SECRET_ACCESS_KEY']
  }
}

注意 :bucket 在 s3 凭证之外，与教程中所说的不同。

希望对大家有所帮助

  • 我现在遇到了回形针和 heroku 的问题。我以后一定会试试的。
