c# - 通过 c# .net 使用 gmail 帐户登录

Question

我正在使用 DotNetOpenID dll 通过 c# .net 通过 gmail 身份验证记录我的示例应用程序

我使用的代码是

protected void Page_Load(object sender, EventArgs e)
    {
        OpenIdRelyingParty rp = new OpenIdRelyingParty();
        var r = rp.GetResponse();
        if (r != null)
        {            
            switch (r.Status)
            {
                case AuthenticationStatus.Authenticated:
                    NotLoggedIn.Visible = false;
                    Session["GoogleIdentifier"] = r.ClaimedIdentifier.ToString();
                    Response.Redirect("About.aspx"); //redirect to main page of your website  
                    break;
                case AuthenticationStatus.Canceled:
                    lblAlertMsg.Text = "Cancelled.";
                    break;
                case AuthenticationStatus.Failed:
                    lblAlertMsg.Text = "Login Failed.";
                    break;
            }
        }
    }

    protected void OpenLogin_Click(object src, CommandEventArgs e)
    {
        string discoveryUri = e.CommandArgument.ToString();
        OpenIdRelyingParty openid = new OpenIdRelyingParty();
        var b = new UriBuilder(Request.Url) { Query = "" };
        var req = openid.CreateRequest(discoveryUri, b.Uri, b.Uri);
        req.RedirectToProvider();
    }

当我点击 gmail 登录按钮时它运行良好，它会转到 gmail 页面并根据需要进行身份验证。

但我的问题是AuthenticationStatus.Authenticated status was failed即使我提供了正确的gmail帐户用户名和密码，身份验证后也是如此

等待有值(value)的回复和评论

按照您的要求。您应该尝试此代码或查看此链接: Gmail credentials for Authentication of ASP.net Website

protected void Page_Load(object sender, EventArgs e)
{
    OpenIdAjaxRelyingParty rp = new OpenIdAjaxRelyingParty();
    var response = rp.GetResponse();
    if (response != null)
    {
        switch (response.Status)
        {
            case AuthenticationStatus.Authenticated:
                NotLoggedIn.Visible = false;
                Session["GoogleIdentifier"] = response.ClaimedIdentifier.ToString();

                var fetchResponse = response.GetExtension<FetchResponse>();
                Session["FetchResponse"] = fetchResponse;
                var response2 = Session["FetchResponse"] as FetchResponse;

                string UserName = response2.GetAttributeValue(WellKnownAttributes.Name.First) ?? "Guest"; // with the OpenID Claimed Identifier as their username.
                string UserEmail = response2.GetAttributeValue(WellKnownAttributes.Contact.Email) ?? "Guest";   

                Response.Redirect("Default2.aspx");
                break;

            case AuthenticationStatus.Canceled:
                lblAlertMsg.Text = "Cancelled.";
                break;
        }

    }
}
protected void OpenLogin_Click(object sender, CommandEventArgs e)
{

    string discoveryUri = e.CommandArgument.ToString();
    OpenIdRelyingParty openid = new OpenIdRelyingParty();

    var url = new UriBuilder(Request.Url) { Query = "" };
    var request = openid.CreateRequest(discoveryUri); // This is where you would add any OpenID extensions you wanted
    var fetchRequest = new FetchRequest(); // to fetch additional data fields from the OpenID Provider

    fetchRequest.Attributes.AddRequired(WellKnownAttributes.Contact.Email);
    fetchRequest.Attributes.AddRequired(WellKnownAttributes.Name.First);
    fetchRequest.Attributes.AddRequired(WellKnownAttributes.Name.Last);
    fetchRequest.Attributes.AddRequired(WellKnownAttributes.Contact.HomeAddress.Country);
    request.AddExtension(fetchRequest);

    request.RedirectToProvider();

}
