使用Google Contacts Api导入联系人C＃

Question

我正在使用Google Contacts Api。我不确定我是否可以发送Auth Token作为参数。

string _token = _google.Token; 
RequestSettings requestSettings = new RequestSettings("AppName",_token); 
ContactsRequest contactsRequest = new ContactsRequest(requestSettings); 

// Get the feed 
Feed<Contact> feed = contactsRequest.GetContacts(); 

我得到401 Unauthorised本代码的响应，但如果我送作为参数的用户名和密码，我能够得到回应。

哎呀，对不起，我第一次没把它弄好。我在一个真正的应用程序中使用这段代码，我只是在代码中做了一些不同的事情，因为我经常刷新令牌。
在任何情况下，这里的正确的逻辑：

 // get this information from Google's API Console after registering your app 
     var parameters = new OAuth2Parameters 
     { 
      ClientId = @"", 
      ClientSecret = @"", 
      RedirectUri = @"", 
      Scope = @"https://www.google.com/m8/feeds/", 
     }; 

     // generate the authorization url 
     string url = OAuthUtil.CreateOAuth2AuthorizationUrl(parameters); 

     // now use the url to authorize the app in the browser and get the access code 
     (...) 

     // get this information from Google's API Console after registering your app 
     parameters.AccessCode = @"<from previous step>"; 

     // get an access token 
     OAuthUtil.GetAccessToken(parameters); 

     // setup connection to contacts service 
     var contacts = new ContactsRequest(new RequestSettings("<appname>", parameters)); 

     // get each contact 
     foreach (var contact in contacts.GetContacts().Entries) 
     { 
      System.Diagnostics.Debug.WriteLine(contact.ContactEntry.Name.FullName); 
     } 

仅供参考，你叫GetAccessToken()对你的代码后，您的参数数据结构将包括AccessToken和RefreshToken领域。如果您存储这两个值，则可以在随后的调用中将它们设置为参数结构（允许您跳过将来要求授权的情况），而不是致电GetAccessToken()，只需致电RefreshAccessToken(parameters)，即可随时访问联系人。合理？在这里，我们来看一看：

 // get this information from Google's API Console after registering your app 
     var parameters = new OAuth2Parameters 
     { 
      ClientId = @"", 
      ClientSecret = @"", 
      RedirectUri = @"", 
      Scope = @"https://www.google.com/m8/feeds/", 
      AccessCode = "", 
      AccessToken = "", /* use the value returned from the old call to GetAccessToken here */ 
      RefreshToken = "", /* use the value returned from the old call to GetAccessToken here */ 
     }; 

     // get an access token 
     OAuthUtil.RefreshAccessToken(parameters); 

     // setup connection to contacts service 
     var contacts = new ContactsRequest(new RequestSettings("<appname>", parameters)); 

     // get each contact 
     foreach (var contact in contacts.GetContacts().Entries) 
     { 
      System.Diagnostics.Debug.WriteLine(contact.ContactEntry.Name.FullName); 
     } 

编辑：

  // generate the authorization url 
      string url = OAuthUtil.CreateOAuth2AuthorizationUrl(parameters); 

      // now use the url to authorize the app in the browser and get the access code 
      (...) 

      // get this information from Google's API Console after registering your app 
      var parameters = new OAuth2Parameters 
      { 
       ClientId = @"", 
       ClientSecret = @"", 
       RedirectUri = @"", 
       Scope = @"https://www.google.com/m8/feeds/", 
       AccessCode = @"<from previous step>", 
      }; 

      // get an access token 
      OAuthUtil.GetAccessToken(parameters); 

      // setup connection to contacts service 
      var contacts = new ContactsRequest(new RequestSettings("<appname>", parameters)); 

      // get each contact 
      foreach (var contact in contacts.GetContacts().Entries) 
      { 
       System.Diagnostics.Debug.WriteLine(contact.ContactEntry.Name.FullName); 
      }
