[不允许的参数：：使用Google Cloud Storage保存图像时的格式

Question

我正在尝试使用载波，雾气和Google云存储来保存图像文件。

所以当我提交数据和图像字段时

<ActionDispatch::Http::UploadedFile>

但出现错误“不允许的参数：:格式”。

这在Amazon S3上很好用，但是我已经为gcp付款了，所以我想在这里保存图像。

请给我一些提示。谢谢

image_uploader.rb

class ImageUploader < CarrierWave::Uploader::Base
  storage :fog

  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end

  def extension_whitelist
    %w(jpg jpeg gif png)
  end
end

fog.rb

CarrierWave.configure do |config|
    config.fog_provider = 'fog/google'

无论您在前端应用程序中使用什么请求客户端，都发送format参数，该参数显然在控制器中是不允许的。可能只是无害format: 'json'。如果是这种情况，您只需在操作中使用except方法过滤此参数即可解决问题：

params.except(:format).require(:reaction).permit(:id, :name, :contents, :reaction_type ,:channel_id, :tag, :target_number, :image, :created_at, :updated_at, :match_option)

和

params.except(:format).permit(:id, :name, :contents, :reaction_type ,:channel_id, :tag, :target_number, :created_at, :updated_at, :match_option, :image)

我相信您需要对提供的雾化配置进行更多更改。首先，我认为对于提供商，您需要Google而不是Goggle。接下来，您需要将aws相关凭证密钥的当前用法更改为google特定密钥（我怀疑这是您实际错误的原因，fwiw）。因此，您需要aws_access_key_id和aws_secret_access_key而不是google_storage_access_key和google_storage_secret_access_key。您可以在以下载波自述文件中看到有关此内容的更多信息：https://github.com/carrierwaveuploader/carrierwave#using-google-storage-for-developers

总的来说，生成的fog.rb看起来像这样：

CarrierWave.configure do |config|
    config.fog_provider = 'fog/google'
    config.fog_credentials = {
        provider:                         'Google',
        google_storage_access_key:        ENV['GOOGLE_ACCESS_KEY'],
        google_storage_secret_access_key: ENV['GOOGLE_SEC_KEY'],
    }
    config.fog_directory  = 'fullout-linemanager-storage'
    config.fog_public     = true
    config.fog_attributes = { }

    config.remove_previously_stored_files_after_update = true
end

希望有帮助！
