使用 Google Cloud Storage 和 Carrierwave 保存圖像時出錯

Question

我使用了carrierwave、fog和AWS S3來保存我的圖像，

但我需要將這種方式更改為 Google Cloud Storage。

我找到了一些使用霧谷歌的方法，但這是過時的。

所以我用沒有霧的carrierwave-google-storage gem嘗試了這個，

但效果不佳。

我在carrierwave-google-storage git page 中做了完全相同的過程。

（鏈接： https : //github.com/metaware/carrierwave-google-storage ）

我附上了我的 image_uploader.rb、carrierwave.rb 和日志消息。

image_uploader.rb

class ImageUploader < CarrierWave::Uploader::Base
  # Include RMagick or MiniMagick support:
  # include CarrierWave::RMagick
  # include CarrierWave::MiniMagick

  # Choose what kind of storage to use for this uploader:
  # storage :file
  storage :gcloud

  # Override the directory where uploaded files will be stored.
  # This is a sensible default for uploaders that are meant to be mounted:
  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end

  # Provide a default URL as a default if there hasn't been a file uploaded:
  # def default_url(*args)
  #   # For Rails 3.1+ asset pipeline compatibility:
  #   # ActionController::Base.helpers.asset_path("fallback/" + [version_name, "default.png"].compact.join('_'))
  #
  #   "/images/fallback/" + [version_name, "default.png"].compact.join('_')
  # end

  # Process files as they are uploaded:
  # process scale: [200, 300]
  #
  # def scale(width, height)
  #   # do something
  # end

  # Create different versions of your uploaded files:
  # version :thumb do
  #   process resize_to_fit: [50, 50]
  # end

  # Add a white list of extensions which are allowed to be uploaded.
  # For images you might use something like this:
  def extension_whitelist
    %w(jpg jpeg gif png)
  end

  # Override the filename of the uploaded files:
  # Avoid using model.id or version_name here, see uploader/store.rb for details.
  # def filename
  #   "something.jpg" if original_filename
  # end
end

CarrierWave.configure do |config|
  config.storage                             = :gcloud
  config.gcloud_bucket                       = 'fullout-linemanager-storage'
  config.gcloud_bucket_is_public             = false
  config.gcloud_authenticated_url_expiration = 600
  # config.gcloud_content_disposition          = 'attachment' // or you can skip this

  config.gcloud_attributes = {
    expires: 600
  }
  config.gcloud_credentials = {
    gcloud_project: "fullout-test",
    gcloud_keyfile: "../fullout-test-01ed5e95d6fd.json"
  }
end

我建議您使用官方的 Ruby 雲存儲客戶端庫

要上傳文件，您可以執行以下操作：

# project_id        = "Your Google Cloud project ID"
# bucket_name       = "Your Google Cloud Storage bucket name"
# local_file_path   = "Path to local file to upload"
# storage_file_path = "Path to store the file in Google Cloud Storage"

require "google/cloud/storage"

storage = Google::Cloud::Storage.new project_id: project_id
bucket  = storage.bucket bucket_name

file = bucket.create_file local_file_path, storage_file_path

puts "Uploaded #{file.name}"
