HTTPS文件上传 [英] HTTPS File Upload

问题描述

我试图通过HTTPS协议将test.txt文件上传到远程服务器。
对于按钮单击，我按如下方式编写代码：

受保护的子btnUploadFile_Click（ByVal sender As Object，ByVal e As EventArgs）处理btnUploadFile.Click
UploadFile（" c：\test.txt"，" https：//remotemachine.com/test/files/"）
结束子

公共子上传文件（ByVal localFile As String，ByVal uploadUrl As String）

试试

Dim req As HttpWebRequest
req = CType（WebRequest.Create（uploadUrl），HttpWebRequest）
req.KeepAlive = True

req.Credentials = New NetworkCredential（" userName"，" password"）
req.ContentType =" Content-Type：multipart / form-data ; boundary = BOUNDRY" req.Method =" POST"

req.AllowWriteStreamBuffering = True

Dim reqStream As Stream
reqStream = req.GetRequestStream（）

Dim rdr As New FileStream（localFile，FileMode.Open）
Dim inData（4096）As Byte

Dim bytesRead = rdr。 Read（inData，0，inData.Length - 1）
while bytesRead> 0
reqStream.Write（inData，0，bytesRead）
bytesRead = rdr.Read（inData，0，inData.Length - 1）
结束时

转发.Close（）
reqStream.Close（）

Dim objWebResponse As System.Net.HttpWebResponse
objWebResponse = CType（req.GetResponse，HttpWebResponse）

Catch ex As WebException
MsgBox（&"错误信息：" + ex.Message）
最后结束尝试

结束子
objWebResponse = CType（req.GetResponse，HttpWebResponse）上引发异常，并带有消息：远程服务器返回错误：（405）方法不允许

任何人都可以告诉我如何克服这个问题。

Hi,
 
I am trying to upload test.txt file to remote server through HTTPS protocol.
for that on button click I have write the code as follows:


Protected Sub btnUploadFile_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnUploadFile.Click
    UploadFile("c:\test.txt", "https://remotemachine.com/test/files/")
End Sub

Public Sub UploadFile(ByVal localFile As String, ByVal uploadUrl As String)

        Try

            Dim req As HttpWebRequest
            req = CType(WebRequest.Create(uploadUrl), HttpWebRequest)
            req.KeepAlive = True

            req.Credentials = New NetworkCredential("userName", "password")
            req.ContentType = "Content-Type: multipart/form-data; boundary=BOUNDRY"
           
            req.Method = "POST"
          
            req.AllowWriteStreamBuffering = True

            Dim reqStream As Stream
            reqStream = req.GetRequestStream()

            Dim rdr As New FileStream(localFile, FileMode.Open)
            Dim inData(4096) As Byte

            Dim bytesRead = rdr.Read(inData, 0, inData.Length - 1)
            While bytesRead > 0
                reqStream.Write(inData, 0, bytesRead)
                bytesRead = rdr.Read(inData, 0, inData.Length - 1)
            End While

            rdr.Close()
            reqStream.Close()
          
            Dim objWebResponse As System.Net.HttpWebResponse
            objWebResponse = CType(req.GetResponse, HttpWebResponse)

        Catch ex As WebException
            MsgBox("Error Message:" + ex.Message)
        Finally
        End Try

End Sub

But it raises an exception at
objWebResponse = CType(req.GetResponse, HttpWebResponse)
with message : The remote server returned an error : (405) Method Not Allowed

Can anyone please let me know as to how can i overcome this issue.

推荐答案

W hat是您要将文件发布到的端点Uri？该端点必须支持POST / PUT方法，否则服务器将拒绝您的请求。

What is the endpoint Uri to which you are posting the file? That endpoint has to support the POST/PUT method, otherwise the server will deny your request.
