使用Google Cloud Storage和Carrierwave保存图像时出错

Question

我正在使用carrierwave，fog和AWS S3来保存我的图像，

但我需要将这种方式更改为谷歌云存储。

我用雾谷歌找到了一些方法，但这已经过时了。

所以我尝试了这个没有雾的运营商波谷歌存储宝石，

但它效果不佳。

我在carrierwave-google-storage git页面中做了完全相同的过程。

(链接： 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.rb

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

我建议您使用官方的 Ruby 云存储客户端库

要上传文件，您可以执行以下操作：

# 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}"

在文档中，您可以找到更多使用 Ruby 在 GCS 中执行其他任务的示例
