我正在使用oauth从桌面应用程序访问Google联系人。我已按照谷歌的说明进行操作:http://code.google.com/intl/iw-IL/apis/gdata/docs/auth/oauth.html#Examples但我遇到了问题

这是代码:

 OAuthParameters parameters = new OAuthParameters()
                                         {
                                             ConsumerKey = CONSUMER_KEY,
                                             ConsumerSecret = CONSUMER_SECRET,
                                             Scope = SCOPE,
                                             Callback = "http://localhost:10101/callback.htm.txt",
                                             SignatureMethod = "HMAC-SHA1"
                                         };
        OAuthUtil.GetUnauthorizedRequestToken(parameters);
        string authorizationUrl = OAuthUtil.CreateUserAuthorizationUrl(parameters);
        Console.WriteLine(authorizationUrl);
        var win = new GoogleAuthenticationWindow(authorizationUrl,parameters);
        win.ShowDialog();
        OAuthUtil.GetAccessToken(parameters);
窗口内的

我有以下内容:

private void BrowserNavigated(object sender, NavigationEventArgs e)
    {
        if (e.Uri.ToString().Contains("oauth_verifier="))
        {
            OAuthUtil.UpdateOAuthParametersFromCallback(e.Uri.ToString(), m_parameters);
            Close();
        }
    }

在最后一行(OAuthUtil.GetAccessToken(参数);)我收到400错误的请求错误,我不明白为什么......

答案 0 :(得分:0)

经过多次游戏......我认为这是访问google api的最简单方法:

Service service = new ContactsService("My Contacts Application");
        service.setUserCredentials("mail@gmail.com", "password");
        var token = service.QueryClientLoginToken();
        service.SetAuthenticationToken(token);
        var query = new ContactsQuery(@"https://www.google.com/m8/feeds/contacts/mail@gmail.com/full?max-results=25000");
        var feed = (ContactsFeed)service.Query(query);
        Console.WriteLine(feed.Entries.Count);
        foreach (ContactEntry entry in feed.Entries)
        {
            Console.WriteLine(entry.Title.Text);
        }

比使用oauth要容易得多......
