编组转储格式错误(0xa)

标签: ruby marshalling

我的哈希:

$settings =
{
  :first_run=>true, :version=>1.01, :game_variables=>{}, :game_switches=>{9=>false}
}

保存代码:

marshal_dump = Marshal.dump($settings)
file = File.new(file_path, 'w')
file.write marshal_dump
file.close

加载代码:

$settings = Marshal.load(File.binread(file_path))

到目前为止,一切仍然有效。但是只要我将另一个变量添加到$ settings hash并保存它然后尝试加载它:

$settings[:test] = 'woohoo!'
save() # saves the hash to disk
load() # loads the hash from disk

会引发错误:

Argument error occured. dump format error(0xa)

解决方案: (感谢ilan berci)

def dump_settings
    File.open(FILENAME,'w') do|file|
      Marshal.dump($settings, file)
    end
  end

  def load_settings
    $settings = if File.exists?(FILENAME)
      File.open(FILENAME) do|file|
        Marshal.load(file)
      end
      else
        create # custom function that fills the $settings for first use
      end
  end

答案 0 :(得分:3)

您正在以二进制模式读取文件,但内容尚未像这样被转储。

使用:

$ settings = Marshal.load(File.open(file_path))
