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 $url,
10                   'User-Agent' => 'Mozilla/4.76 (Win98; U)',
11
12                   Content_Type =>'form-data',
13                   Content => ,
14                         waspaction=>"FILEUPLOAD",
15                         swrFile=>[$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

1require 'rest_client'
2RestClient.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.
1Open3.popen3('curl<and your parameters>') do |input, output, error|
2# do something
3end

   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
   #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
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
