链接在C＃中的当前状态更新，获取错误（401）未授权

基本上我想保存在数据库中的AccessToken，AccessTokenSecret和验证，当我想代表用户我可以发布'链接'状态更新。链接在C＃中的当前状态更新，获取错误（401）未授权

第一次获取这些访问令牌，然后使用它，我可以成功地更新状态。但我存储它，然后20-30分钟后，如果我尝试与存储的令牌相同的更新状态调用，我得到401错误。

是否存储令牌并在以后使用它的正确方法。或每次用户需要显示允许屏幕并且必须获得新的令牌？

以下是我的功能。我正在使用this library

public string makeRequestForStatusUpdateOnLinkedIn(String txtAccessToken, String txtAccessTokenSecret, String txtoAuth_verifier,String status) 
     { 
private oAuthLinkedIn _oauth = new oAuthLinkedIn() 
      _oauth.Token = txtAccessToken; 
      _oauth.TokenSecret = txtAccessTokenSecret; 
      _oauth.Verifier = txtoAuth_verifier; 

      string xml = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>"; 
      xml += "<current-status>" + status + ".</current-status>"; 


      string response = _oauth.APIWebRequest("PUT", "http://api.linkedin.com/v1/people/~/current-status", xml); 

      if (response == "") 
       return "Your new status updated successfully !"; 
      else 
      { 
       return "Sorry ! Error at server side!"; 
      } 
     }

最后没有使用任何其他库。我只是遵循LinkedIn文档的步骤，并得到我想要的。下面是解决我的问题，可以帮助他人的代码。

如果你回答了你自己的问题，并乐此不疲，随时将其标记为回答。 – Noctis

请试试这个代码

protected void Page_Load(object sender, EventArgs e)  

    {  

    // create from config file  

    var config = LinkedInApiConfiguration.FromAppSettings("LogiDemo.LinkedInConnect");  

    // or manually  

    // var config = LinkedInApiConfiguration("api key", "api secret key"); 


    // get the APIs client 


    var api = new LinkedInApi(config); 


    var scope = AuthorizationScope.ReadBasicProfile | AuthorizationScope.ReadEmailAddress;  

    var state = Guid.NewGuid().ToString();  

    var redirectUrl = "http://localhost:49965/WebForm1.aspx"; 

    var url = api.OAuth2.GetAuthorizationUrl(scope, state, redirectUrl); 

    Response.Redirect(url.OriginalString);  

    }
