我想使用VB.Net上传文件到Sinatra Web服务，我不知道如何配置任何一端。当我运行VB.Net应用程序，西纳特拉总是用代码404响应下面是VB.Net代码，这是我从另一个SO后转换：试图使用vb.net上传文件到sinatra
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim responseData As String = ""
Dim rdr As FileStream = New FileStream("X:\QueryTxtFiles\Query\CDA Curncy_9_1_2011.fqy", FileMode.Open)
Dim req As HttpWebRequest = DirectCast(WebRequest.Create("http://finqueryserver:9898"), HttpWebRequest)
req.Method = "POST" ' you might use "POST"
req.ContentLength = rdr.Length
req.AllowWriteStreamBuffering = True
Dim reqStream = DirectCast(req.GetRequestStream(), Stream)
Dim inData(rdr.Length) As Byte
' Get data from upload file to inData
Dim bytesRead As Integer = rdr.Read(inData, 0, rdr.Length)
' put data into request stream
reqStream.Write(inData, 0, rdr.Length)
rdr.Close()
Try
req.GetResponse()
Catch ex As Exception
responseData = "An error occurred: " & ex.Message
End Try
' after uploading close stream
reqStream.Close()
End Sub
这里是西纳特拉代码：
require 'rubygems'
require 'sinatra'
post '/:name/:filename' do
puts "got here"
begin
name = params[:name]
rescue
name = "no name"
end
begin
filename = params[:filename]
rescue
filename = "no filename"
end
end
（我从来没有看到“来到这里”。）Sinatra代码是基于使用cURL的教程，我不是。我也试着
post "/:filename'
这给404也和简单
post "/"
这确实显示“来到这里”，但显然是无用的，因为我需要处理的文件。
很明显，我是两个新手，这不可能很难，但我不知道该怎么做。
谢谢。
