我試圖使用API文檔上傳到Rapidshare。我已經看過很多文章，但仍然無法完成「完成」。目前，我不斷獲取以下響應錯誤：Rapidshare API上傳文件
ERROR: Subroutine invalid. (b6ba5d82)
我用了以下文件：
http://images.rapidshare.com/apidoc.txt
，並用我的計算器找到了一個例子：
Upload files with HTTPWebrequest (multipart/form-data)
我使用的是以下代碼：
Sub Main
Dim freeurl As String = "http://api.rapidshare.com/cgi-bin/rsapi.cgi?sub=nextuploadserver"
Dim req As WebRequest = WebRequest.Create(freeurl)
Dim response = req.GetResponse().GetResponseStream()
Dim reader As New StreamReader(response)
Dim nextfreeserver = reader.ReadToEnd()
req = Nothing
response = Nothing
reader= Nothing
Dim login As String = "********"
Dim password As String = "********"
Dim filename As string = "test12345.txt"
Dim filepath = "C:\Users\Public\Documents\" & filename
Dim uploadurl As String = "https://rs" & nextfreeserver & ".rapidshare.com/cgi-bin/rsapi.cgi?sub=upload"
uploadurl = uploadurl & "&login=" & login & "&password=" & password & "&filename" & filename & "&filecontent=" & filepath
Dim nvc As NameValueCollection = new NameValueCollection()
nvc.Add("sub", "upload")
nvc.Add("login", login)
nvc.Add("password", password)
Dim resp As String = ""
resp = HttpUploadFile("https://rs" & nextfreeserver & ".rapidshare.com/cgi-bin/rsapi.cgi", filepath, "filecontent", "application/octet-stream", nvc)
End Sub
Public Shared Function HttpUploadFile(url As String, file As String, paramName As String, contentType As String, nvc As NameValueCollection) As string
Dim boundary As String = "---------------------------" & DateTime.Now.Ticks.ToString("x")
Dim boundarybytes As Byte() = System.Text.Encoding.ASCII.GetBytes(vbCr & vbLf & "--" & boundary & vbCr & vbLf)
Dim wr As HttpWebRequest = DirectCast(WebRequest.Create(url), HttpWebRequest)
wr.ContentType = "multipart/form-data; boundary=" & boundary
wr.Method = "POST"
wr.KeepAlive = True
wr.Credentials = System.Net.CredentialCache.DefaultCredentials
Dim rs As Stream = wr.GetRequestStream()
Dim formdataTemplate As String = "Content-Disposition: form-data; name=""{0}""" & vbCr & vbLf & vbCr & vbLf & "{1}"
For Each key As String In nvc.Keys
rs.Write(boundarybytes, 0, boundarybytes.Length)
Dim formitem As String = String.Format(formdataTemplate, key, nvc(key))
Dim formitembytes As Byte() = System.Text.Encoding.UTF8.GetBytes(formitem)
rs.Write(formitembytes, 0, formitembytes.Length)
Next
rs.Write(boundarybytes, 0, boundarybytes.Length)

Dim bytesRead As Integer = 0

rs.Write(buffer, 0, bytesRead)
End While
fileStream.Close()
Dim trailer As Byte() = System.Text.Encoding.ASCII.GetBytes(vbCr & vbLf & "--" & boundary & "--" & vbCr & vbLf)
rs.Write(trailer, 0, trailer.Length)
rs.Close()
Dim wresp As WebResponse = Nothing
Try
wresp = wr.GetResponse()
Dim stream2 As Stream = wresp.GetResponseStream()
Dim reader2 As New StreamReader(stream2)
return reader2.ReadToEnd()
If wresp IsNot Nothing Then
wresp.Close()
wresp = Nothing
End If
Finally
wr = Nothing
End Try
End Function
