Rest客戶端發佈錯誤

Question

當運行下面的代碼發佈上傳我的參數文件，我得到下面的錯誤消息。我無法弄清楚這一點，不勝感激。

錯誤：

uploadhttp.rb:11:in `size': No such file or directory @ rb_file_s_size - hfs.exe (Errno::ENOENT) from uploadhttp.rb:11:in `<main>' 

代碼：

begin 
    RestClient::Request.execute(:method => :post, :url => 
'http://my external ip:8080/upload/', :timeout => 30, :open_timeout => 30, 
:name_of_file_param => File.new("C:\\Users\\Michael\\Downloads\\#{nfile}")) 
    filesize=(File.size("#{nfile}")) 
    result=(filesize.to_s.reverse.gsub(/(\d{3})(?=\d)/, '\\1,').reverse) 
    print "#{result} bytes were uploaded to Mikez http file Server" 

    rescue RestClient::ExceptionWithResponse => err 
    puts "an error has occured potential timeout" 
end 

Answer 1

的文件大小應該是這樣的

filesize=(File.size("C:\\Users\\Michael\\Downloads\\#{nfile}"))
