我已经编写了用于创建多部分表单数据请求的 RUBY 代码。它在 ruby​​ 1.9.3 中运行良好，但在 ruby​​ 2.0 补丁 247 和补丁 0 中引发错误。

错误是，

/home/mohanrajr/Ruby/multipart/multipart_stream.rb:16:in `read': wrong number of arguments (2 for 1) (ArgumentError)
    from /home/mohanrajr/.rvm/rubies/ruby-2.0.0-p247/lib/ruby/2.0.0/net/http/generic_request.rb:205:in `copy_stream'
    from /home/mohanrajr/.rvm/rubies/ruby-2.0.0-p247/lib/ruby/2.0.0/net/http/generic_request.rb:205:in `send_request_with_body_stream'

    from multipart_post.rb:4:in `<main>'
