I don''t know what is going on.
And here is my c# code
using System;
using System.Collections.Generic;
using System.Text;
using System.Web;
using System.Net;
using System.IO;
namespace ConsoleApplication13
{
class Program
{
static void Main(string[] args)
{
Program test = new Program();
test.firstmethod();
}
private void firstmethod()
{
string url = "http://localhost:3002/filelink/upload2";
string[] files = { "c:\\test.txt" };
string logpath = null;
UploadFilesToRemoteUrl(url, files, logpath);
}
private void UploadFilesToRemoteUrl(string url, string[] files,
string logpath)
{
long length = 0;
string boundary = "----------------------------" +
DateTime.Now.Ticks.ToString("x");
HttpWebRequest httpWebRequest2
(HttpWebRequest)WebRequest.Create(url);
httpWebRequest2.ContentType = "multipart/form-data;
boundary=" + boundary;
httpWebRequest2.Method = "POST";
httpWebRequest2.KeepAlive = true;
httpWebRequest2.Credentials
System.Net.CredentialCache.DefaultCredentials;
Stream memStream = new System.IO.MemoryStream();
byte[] boundarybytes2
System.Text.Encoding.ASCII.GetBytes("--" + boundary +
"\r\n");
byte[] boundarybytes
System.Text.Encoding.ASCII.GetBytes("\r\n--" + boundary +
"\r\n");
memStream.Write(boundarybytes2,0,boundarybytes2.Length);
length += boundarybytes2.Length;
string headerTemplate = "Content-Disposition: form-data;
name=\"{0}\"; filename=\"{1}\"\r\n Content-Type:
application/octet-stream\r\n\r\n";
for(int i=0;i<files.Length;i++)
{
string header
string.Format(headerTemplate,"any_file",files[i]);
byte[] headerbytes System.Text.Encoding.UTF8.GetBytes(header);
memStream.Write(headerbytes,0,headerbytes.Length);
length += headerbytes.Length;
FileStream fileStream = new FileStream(files[i],
FileMode.Open, FileAccess.Read);
byte[] buffer = new byte[1024];
int bytesRead = 0;
while ( (bytesRead = fileStream.Read(buffer, 0,
buffer.Length)) != 0 )
{
memStream.Write(buffer, 0, bytesRead);
length += bytesRead;
}
memStream.Write(boundarybytes,0,boundarybytes.Length);
length += boundarybytes.Length;
fileStream.Close();
}
httpWebRequest2.ContentLength = memStream.Length;
Stream requestStream = httpWebRequest2.GetRequestStream();
memStream.Position = 0;
byte[] tempBuffer = new byte[memStream.Length];
memStream.Read(tempBuffer,0,tempBuffer.Length);
memStream.Close();
requestStream.Write(tempBuffer,0,tempBuffer.Length );
requestStream.Close();
WebResponse webResponse2 = httpWebRequest2.GetResponse();
Stream stream2 = webResponse2.GetResponseStream();
StreamReader reader2 = new StreamReader(stream2);
Console.WriteLine(reader2.ReadToEnd());
webResponse2.Close();
httpWebRequest2 = null;
webResponse2 = null;
}
}
}
Here is My ruby on rails code
class FilelinkController < ApplicationController
require "ftools"
scaffold :filelink
def index
redirect_to :action => "list"
end
def list
@filelink = Filelink.find_all
end
def uploads
link = String.new()
@link = Date.today().strftime("%d_%m_%y").to_s()
@filelink = Filelink.new()
@filelink[''patientname''] =
@params[''patientname'']
@filelink[''filelink''] =
"#{RAILS_ROOT}/public/file/"+@link+".txt"
File.open(@filelink[''filelink''], "wb") { |f|
f.write(@params[''any_file''].read) }
#do |f|
#f.write(@params[''any_file''].read)
#end
@filelink.save
redirect_to :action => "list"
end
###The Used Part
def upload2
if File.size?(@params[''any_file''])>0
File.open("#{RAILS_ROOT}/public/file/try.txt", "wb")
do |f|
f.write(@params[''any_file''].read)
end
else
redirect_to :action =>"list"
end
redirect_to :action =>"list"
end
#####
end
And here is the form
<html>
<head>
<b><title>Upload file form</title></b>
</head>
<body>
<h1><b>Add a patient records</b></h1>
<form action="/filelink/upload2" name = "newrecord"
method="POST"
enctype="multipart/form-data"/>
<p><label>The HeartBeat file
<b>:</b></label><br/><input
type="file" name="any_file" accept = "text/plain"
/></p>
<br/>
<input type="submit" name="Upload" value =
"upload"/>
</form>
</body>
</html>
For more information, i use Aptana as the development platform of ror,
and i use visual studio.net 2005 as the c# development platform.
