在服务器上发布时无法将文件上传到保管箱

Question

我正在尝试将文件上传到保管箱。当我在本地运行时，文件已上传并且代码可以正常工作。但是文件在服务器上发布时永远不会上传。我遇到以下错误。

无法从程序集 'System.Net.Primitives, Version=4.0.0.0, Culture=neutral, PublicKeyToken=*********'.

加载类型 'System.Security.Authentication.SslProtocols'

我正在尝试使用下面的代码示例上传它

public sub uploadtodropbox()
  Using httpclient As New HttpClient
                        httpclient.Timeout = TimeSpan.FromMinutes(20)
                        Dim _DropboxClient = New DropboxClient(ApiKeyDropBox, config)
                        Dim resultstring As String = UploadToDB(_DropboxClient, dropboxdir, docName, fileBytes)
                        _DropboxClient.Dispose()
                        If Not resultstring = "RanToCompletion" Then
                            ErrorMsg &= "The following error occured: " & resultstring
                        End If
                    End Using

结束子

这是上传到 Dropbox 的功能

Private Function UploadToDB(_DropboxClient As DropboxClient, Directory As String, Filename As String, Content As [Byte]()) As String
    Try
        Dim result As String = "Unknown"
        Dim trycnt As String = 0
        Dim tryLimit As String = 20
        Dim respnse As Task(Of FileMetadata)
        Using _mStream = New MemoryStream(Content)
            respnse = _DropboxClient.Files.UploadAsync(Convert.ToString(Directory & Convert.ToString("/")) & Filename, WriteMode.Overwrite.Instance, body:=_mStream)
            While Not respnse.IsCompleted And trycnt < tryLimit
                Threading.Thread.Sleep(1000)
                trycnt += 1
                result = respnse.Status.ToString()
            End While
            UploadToDB = result
        End Using

结束尝试结束函数。

我试过不使用 httpclient 然后我收到这个错误：

'Dropbox.Api.DropboxRequestHandlerOptions' 的类型初始值设定项引发异常。

谢谢

Answer 1

我去答题。我的 system.Net.primitives 程序集在将文件上传到 Dropbox 时出现问题。我需要做的就是删除引用，并且 System.Net.Http 的版本在 web.config 文件中设置错误。一旦我在配置中设置它，一切正常。

对于证书，我已将 on post 设置回验证并允许在事件处理程序中生成的证书。
