我找到了这个并且非常适合我。


BOUNDARY = "AaB03x"

def encode_multipartformdata(parameters = {})
  ret = String.new
  parameters.each do |key, value|
    unless value.empty?
      ret << "\r\n--" << BOUNDARY << "\r\n"
      ret << "Content-Disposition: form-data; name=\"#{key}\"\r\n\r\n"
      ret << value
    end
  end
  ret << "\r\n--" << BOUNDARY << "--\r\n"
end

已发布here！祝你好运，如果你遇到这个问题，我希望这个对你有用！

【解决方案2】：

尝试调整应用的 apache 安全设置，将其放入您的虚拟主机配置中：

<IfModule mod_security.c>
  SecFilterEngine Off
  SecFilterScanPOST Off
</IfModule>

有时这会处理/tmp 中的部分文件并阻止上传完成。
