Question

如果我的最终用户被定向到Twitter的Oauth页面并返回我们的网站，那么使用Linq to Twitter WebAuthorizer将推文发布到Twitter是没有问题的。以这种方式使用WebAuthorizer效果很好。

但是，如果我尝试存储最终用户的Oauth凭据并将其用于Tweet，我会收到401 Unauthorized错误：

LinqToTwitter.TwitterQueryException：无效或过期的令牌---＆gt; System.Net.WebException：远程服务器返回错误：（401）未经授权。 at LinqToTwitter.TwitterExecute.PostToTwitter [T]（String url，IDictionary 2 postData, Func 2 getResult）---内部异常堆栈跟踪结束---在LinqToTwitter.TwitterExecute.PostToTwitter [T]（String url，IDictionary {{ 1}} 2 getResult）LinqToTwitter.StatusExtensions.UpdateStatus（TwitterContext ctx，String status，Decimal latitude，Decimal经度，String placeID，Boolean displayCoordinates，String inReplyToStatusID，Boolean trimUser，Action`1 callback）at LinqToTwitter.StatusExtensions.UpdateStatus（TwitterContext） ctx，String status）位于External_WCPages_v12_Test_TwitterTest.Page_Load（对象发送者，EventArgs）中的外部_WCPages_v12_Test_TwitterTest.StoredCredentialsSingleUserAuthorizer（）位于C：\ TFS \ SC \ Weblink_Connect-Development \ CWT \ External \ WCPages \ v12 \ Test \ TwitterTest.aspx.vb：第177行e）在C：\ TFS \ SC \ Weblink_Connect-Development \ CWT \ External \ WCPages \ v12 \ Test \ TwitterTest.aspx.vb：第65行

我包括处理Linq到Twitter请求的主要功能。请帮忙，我做错了什么？我已尝试发布2.106,2.107,2.108和截至2013年9月19日的最新变更集。

看起来问题是你的OAuthToken和AccessToken是向后的。这是您应该使用的代码：

    Private Sub StoredCredentialsWebAuthorizer()
        'Comment: Triggered on PostBack

        Dim objCredentials As IOAuthCredentials = New InMemoryCredentials
        'For Testing: Dim objCredentials As IOAuthCredentials = New SingleUserInMemoryCredentials
        'For Testing: Dim objCredentials As IOAuthCredentials = New SessionStateCredentials

        objCredentials.ConsumerKey = Me.ConsumerKey
        objCredentials.ConsumerSecret = Me.ConsumerSecret
        objCredentials.OAuthToken = Me.SavedToken        ' <= here
        objCredentials.AccessToken = Me.SavedTokenSecret ' <= and here

        mobj_WebAuthorizer = New WebAuthorizer

        mobj_WebAuthorizer.Credentials = objCredentials

        'For Testing: Call mobj_WebAuthorizer.CompleteAuthorization(Request.Url)

        mobj_TwitterContext = New TwitterContext(mobj_WebAuthorizer)

        'BUG:  SingleUserAuthorizer doesn't seem to work with the saved credentials from database
        mobj_TwitterContext.UpdateStatus("Test Tweet using LinqToTwitter WebAuthorizer ( using stored credentials ) : " & Date.Now.Millisecond.ToString)
     End Sub

感谢你的帮助，乔。

我的OAuthToken并非以[TwitterAccnt＃] - xxxxx开头。我对我的方法进行了一些验证，并立即以我的方式看到错误。

Private Sub Authorize(Optional UseSavedUserCredentials As Boolean = True)
    'Comment: Triggered on PostBack
    Dim objCredentials As IOAuthCredentials = New InMemoryCredentials

    objCredentials.ConsumerKey = Me.ConsumerKey
    objCredentials.ConsumerSecret = Me.ConsumerSecret

    If UseSavedUserCredentials = True Then
        If Me.SavedToken.Contains("-") = True And Me.SavedTokenSecret.Contains("-") = False Then
            objCredentials.OAuthToken = Me.SavedToken
            objCredentials.AccessToken = Me.SavedTokenSecret
        Else
            Throw New Exception("Incorrect credentials<br/><br/>")
        End If
    Else
        If Me.DevAccountToken.Contains("-") = True And Me.DevAccountTokenSecret.Contains("-") = False Then
            objCredentials.OAuthToken = Me.DevAccountToken
            objCredentials.AccessToken = Me.DevAccountTokenSecret
        Else
            Throw New Exception("Incorrect credentials<br/><br/>")
        End If
    End If

    mobj_WebAuthorizer = New WebAuthorizer

    mobj_WebAuthorizer.Credentials = objCredentials

    mobj_TwitterContext = New TwitterContext(mobj_WebAuthorizer)
End Sub

无法使用已保存的Oauth凭据将Linq的推文发布到Twitter
