最近郁闷的一个问题：关于Ruby和perl的，有兴趣的看看

1 #!/usr/bin/perl -w
2 use LWP;
3 use vars '@ISA';
4 @ISA = 'LWP::UserAgent';
5
6 sub get_file{
7     my $url = 'https//www.google.com';
8     my $agent = __PACKAGE__->new;
9     $response = $agent -> request(POST $url,
10                     'User-Agent' => 'Mozilla/4.76 [en] (Win98; U)',                    
11            
12                     Content_Type =>'form-data',
13                     Content => [  fileName => [$fname],
14                           waspaction=>"FILEUPLOAD",
15                           swrFile=>[$fname]
16                                         ]
17                 );
18     #$response->is_success or die "$url: ", $response->message, "\n";
19     my $content = $response->content;
20 }
21
22 这段代码，我用ruby改写，如下：
23 def get_rac
24     url = URI.parse('https:/www.google.com');
25     #agent = __PACKAGE__.new;
26     
27      req = Net::HTTP::Post.new(url.path)
   　　 req.basic_auth $uid, $pwd
28     req.set_form_data({:fileName => [$fname],:waspaction=>"FILEUPLOAD",:swrFile=>
29 [$fname]}, ';')
30     
31   
32     res = Net::HTTP.new(url.host, url.port).start {|http| http.request(req) }
33
34     content = res;
35     puts res.body
36 end
37 报错：end of file reached

66 不知道是什么问题。
现在貌似有点头绪了，问题就出在：
req.set_form_data({:fileName => [$fname],:waspaction=>"FILEUPLOAD",:swrFile=>
[$fname]}, ';')
这里。ruby中的意义与perl是不同的，这个地方；


  How to perform a file upload (multipart post) with Ruby

  

      Ruby posted about 1 year ago by christian
  
  

　　You have at least 5 options:

• Stanislav Vitvitskiy’s solution
  
• RestClient
  

   1  require 'rest_client'
   2  RestClient.post 'http://localhost:3000/foo', fields_hash.merge(:file => File.new('/path/to/file'))

• The curb gem
  
• The multipart-post Net:HTTP extension
  
• Calling curl from Ruby with, for example, Open3.
     1  Open3.popen3('curl  <and your parameters>') do |input, output, error|
     2  # do something
     3  end
  

  
  

      Tagged post, multipart, curl, ruby, restclient, upload
我用了第一种方法，奇怪的是发到一半，会有报错：

Code
class Multipart  
   def initialize( file_names )  
     @file_names = file_names  
   end  
   def post(url,user,password)  
     boundary = '---------------------------7d9b914b082e'  
     parts = []  
     streams = []
     @file_names.each do |param_name, filepath|  
       pos = filepath.rindex('/')
       filename = filepath[pos + 1, filepath.length - pos]
       #puts param_name.to_s
       #puts filepath
       parts << StringPart.new("--" + boundary + "\r\n" +  
       "Content-Disposition: form-data; name=\"" + param_name.to_s + "\"; filename=\"" + filename + "\"\r\n" +  
       "Content-Type: text/plain\r\n\r\n")
       stream = File.open(filepath, "rb")  
       streams << stream  
       parts << StreamPart.new(stream, File.size(filepath))  
     end  
     parts << StringPart.new("\r\n--" + boundary + "--\r\n" )  
     post_stream = MultipartStream.new( parts )  
     #url = URI.parse( to_url )
     
     http = Net::HTTP.new(url.host, url.port)   
     http.use_ssl = true
     req = Net::HTTP::Post.new(url.path)
     req.basic_auth "admin","admin"  
     req.content_length = post_stream.size  
     req.content_type = 'multipart/form-data; boundary=' + boundary  
     req.body_stream = post_stream
     res = Net::HTTP.new(url.host, url.port).start{|http| http.request(req)}  
     streams.each do |stream|  
       stream.close();  
     end  
     res  
   end  
end  
class StreamPart  
   def initialize(stream, size)  
     @stream, @size = stream, size  
   end  
   def size  
     @size  
   end  
   def read(offset, how_much)  
     @stream.read(how_much)  
   end  
end  
class StringPart  
   def initialize(str)  
     @str = str  
   end  
   def size  
     @str.length  
   end  
   def read(offset, how_much)  
     @str[offset, how_much]  
   end  
end

截包分析：发小点的文件是可以发全的。大一点的文件发了一半就不能继续上传文件了。实在找不到错误的地方。是
不是少设置了什么参数
