为什么这段代码不起作用？ [英] why this code not work?
问题描述
Private Sub Button1_Click（发件人为对象，e为EventArgs）处理Button1.Click
Dim ImageBinary（）As 字节
Dim Header1 As Byte ，Header2 As 字符串
Dim BHeader1（）As Byte ，BHeader2（）As Byte ， Buffer（）As Byte
Dim boundary As String
Dim fPath As String ，fName As String
Dim Headers As String
Dim X As New Collection
Dim wbody As Byte
wbody = TextBox1.Text
fPath = C：\ Users \ 형민\Desktop\이미지업로드\
FNAME = DIR（fPath&安培; *。jpg ）
Do Len（fName）
X.Add（fName，fName）
fName = Dir $（）
循环
boundary = 26036217909135
fName = X（ Int（Rnd（）* X.Count + 1））
ImageBinary = IO.File.ReadAllBytes（fPath& fName）
BHeader1 = System.Text.Encoding.Default.GetBytes（拆分（wbody， wBinary ）（0））
BHeader2 = System.Text。 Encoding.Default.GetBytes（Split（wbody， wBinary ）（1））
Dim DS As New MemoryStream
DS.Write（BHeader1,0，BHeader1.Length）
DS.Write（ImageBinary，0，ImageBinary.Length）
DS.Write（BHeader2 ，0，BHeader2.Length）
DS.Position = 0
ReDim Buffer （DS.Length）
DS.Read（Buffer，0，Buffer.Length）：DS.Close（）
使用WinHttp
。打开（ POST ， http： // imgdb.kilho.net/upload.php）
.SetRequestHeader（ User-Agent， Mozilla / 5.0（Windows NT 6.1; rv：43.0）Gecko / 20100101 Firefox / 43.0）
.SetRequestHeader（ Referer ， http://image.kilho.net）
。 SetRequestHeader（ Content-Type， multipart / form-data; boundary = ---------------------------& boundary）
.SetRequestHeader（ Content-Length，UBound（Buffer） ）
.Send（Buffer）
.WaitForResponse（）：Application.DoEvents（）
Headers = .GetAllResponseHeaders
MsgBox（.ResponseText）
End
End Sub
但服务器消息你没有权限访问upload.php服务器
为什么..？

为什么..？
错误消息e很明确：
你没有权限访问upload.php服务器
最有可能原因是您不是正确的用户：您正在尝试访问特定用户桌面，除非您具有提升的权限，或者您是该用户，系统将阻止您。由于这似乎是基于Web的代码，因此它可能是在IIS下运行而不是作为您的用户身份。
而不是尝试将其保存到特定用户，要么在服务器上创建一个每个人都可以访问的文件夹（危险），要么使用Server.MapPath访问网站根目录下的文件夹来保存文件。

but server message "you don't have permission acess upload.php server"
why..?
The error message is pretty explicit:
you don't have permission acess upload.php server
The most likely reason is that you aren't the right user: You are trying to access a specific users Desktop, and unless you have elevated permissions or you are that user the system is going to stop you. And since this seems to be web based code, the chances are that it is running under IIS rather than as your user identity.
Instead of trying to save it to a specific user, either have a folder created on the server that everyone can access (dangerous), or use Server.MapPath to access a folder under your website root directory to hold the file(s).
