使用Nemiro OAuth库在Webforms中进行Google身份验证 [英] Using Nemiro OAuth library for Google authentication in Webforms
问题描述
我正在尝试使用Nemiro库在Webforms asp.net项目中针对Google进行身份验证.该库文档位于 Nemiro GoogleClient文档
I am trying to use Nemiro library to authenticate against Google in a Webforms asp.net project. This library documentation is at Nemiro GoogleClient Documenation
我有一个名为ExternalLogin.aspx的简单aspx页面，其标记和代码隐藏如下.
I have a simple aspx page called ExternalLogin.aspx, whose markup and code-behind are as given below.
问题
使用我拥有的代码，当单击Login using Google按钮时，用户不会被定向到Google的授权页面.我的代码中缺少什么原因?
With code that I have, when Login using Google button is clicked, then user does not get directed to Google's authorization page. What is missing in my code that is causing this?
标记
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="ExternalLogin.aspx.cs" Inherits="ExternalLogin" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Button ID="btnGoogle" runat="server" Text="Login using Google" OnClick="btnGoogle_Click" />
</div>

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using Nemiro;
using Nemiro.OAuth.Clients;
using Nemiro.OAuth;
public partial class ExternalLogin : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void btnGoogle_Click(object sender, EventArgs e)
{
var result = OAuthWeb.VerifyAuthorization();
if (result.IsSuccessfully)
{
var user = result.UserInfo;
Response.Write(String.Format("User ID: {0}<br />", user.UserId));
Response.Write(String.Format("Name: {0}<br />", user.DisplayName));
Response.Write(String.Format("Email: {0}", user.Email));
}
}
}
我还在Application_Start事件中定义了Google OAuth的密钥，如下所示.
I have also defined the keys for Google OAuth in Application_Start event as below.
void Application_Start(object sender, EventArgs e)
{
Nemiro.OAuth.OAuthManager.RegisterClient(
new Nemiro.OAuth.Clients.GoogleClient(
"some-value-1",
"some-value-2"
));
}
推荐答案
我认为您应该查看OAuthWeb.RedirectToAuthorization方法.这是 API文档供您参考.因此，只需在btnGoogle_Click中调用此方法，然后在Page_Load事件处理程序中验证您的授权即可.
I think you should be looking at OAuthWeb.RedirectToAuthorization method. Here's the API doc for your reference. So just call this method in your btnGoogle_Click, and then verify your authorization in Page_Load event handler.
这是示例代码:
protected void btnGoogle_Click(object sender, EventArgs e)
{
OAuthWeb.RedirectToAuthorization("Google", new Uri(Request.Url, "ExternalLogin.aspx").AbsoluteUri);
}
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostback)
{
var result = OAuthWeb.VerifyAuthorization();
if (result.IsSuccessfully)
{
var user = result.UserInfo;
Response.Write(String.Format("User ID: {0}<br />", user.UserId));
Response.Write(String.Format("Name: {0}<br />", user.DisplayName));
Response.Write(String.Format("Email: {0}", user.Email));
}
}
}
此外，如果您想在其他页面上验证授权结果，只需在URI构造函数中更改页面名称，然后将验证代码放在新页面的Page_Load事件中即可.
Also, if you'd like to verify the authorization results on a different page, just change the page name in the URI constructor, and put verification code in the Page_Load event of your new page.
