使用VB.NET驗證在線Sharepoint的用戶

我是全新的連接Sharepoint Online與vb.net程序，任何建議肯定會有所幫助。使用VB.NET驗證在線Sharepoint的用戶

我已經加入了2 的.dll文件參考，Microsoft.Sharepoint.Client和Microsoft.Sharepoint.Client.Runtime。他們從鏈接SharePoint Server 2013 Client Components SDK 下載。

下面將我的代碼，

Imports Microsoft.SharePoint.Client 
Imports Microsoft.SharePoint 
Imports Microsoft 
Imports System.Net 
Imports System.Security 

Public Class FilesRetrievalFromSharePoint 
Inherits System.Web.UI.Page 

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load 


    Using ClientContext As New ClientContext("https://sample.sharepoint.com/Home.aspx") 

     Dim password As New System.Security.SecureString() 

     For Each c As Char In "[email protected]".ToCharArray() 
      password.AppendChar(c) 
     Next 


     ClientContext.Credentials = New SharePointOnlineCredentials("[email protected]", password) 
     Dim web As Web = ClientContext.Web 

     ClientContext.Load(web) 
     ClientContext.ExecuteQuery() 

    End Using 
End Sub

而其他一些類低於末次

Private Class SharePointOnlineCredentials 
    Implements ICredentials 

    Private password As SecureString 
    Private v As String 

    Public Sub New(v As String, password As SecureString) 
     Me.v = v 
     Me.password = password 
    End Sub 

    Public Function GetCredential(uri As Uri, authType As String) As NetworkCredential Implements ICredentials.GetCredential 
     Throw New NotImplementedException() 
    End Function 
End Class

，我會打在ExecuteQuery()的錯誤是

An exception of type 'System.Net.WebException' occurred in Microsoft.SharePoint.Client.dll but was not handled in user code

Additional information: The remote server returned an error: (403) Forbidden.

我知道這是由於身份驗證問題，並且Sharepoint網址適用於公司中的授權用戶。假設代碼中的憑證屬於授權用戶。

是由於錯誤的編碼或可能是由於企業的IT安全策略？

更改線路使用ClientContext作爲新ClientContext（「https://sample.sharepoint.com/Home.aspx 」）

到使用ClientContext作爲新ClientContext（「 https://sample.sharepoint.com」）如果您打算使用其他網站使用使用ClientContext作爲新ClientContext（「https://sample.sharepoint.com/sites/yoursite」）

不要使用該頁面連接到該網站。

hi @Guruparan，謝謝你的回覆。不，不過，它仍然給我403錯誤。 –

@TanStanley，你是否正確地更換了網站的網址？ https://sample.sharepoint.com –

用於測試目的我已經使用ClientContext作爲新的ClientContext（「https://sample.sharepoint.com」）。但是，我可以從Web應用程序獲得響應之前發生錯誤。 –
