5、继续，填写完毕后，点击Register application，如下图：
6、至此，我们已经成功拿到Client ID和Client Secret。另外，此页面还可以更改步骤5填写的相关信息，如下图：
第二步，代码部分。实现GitHub第三方登录
1、Login.aspx 代码
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Login.aspx.cs" Inherits="GitHubLogin.Login" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<a href="https://github.com/login/oauth/authorize?client_id=xxxxxxxxxxxxxxxxxxxxxx&state=STATE&redirect_uri=http://www.kudsu.xyz/">github登录</a>
</div>
</form>
</body>
</html>
2、Login.aspx.cs 代码
using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Text;
using System.Threading.Tasks;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace GitHubLogin
{
public partial class Login : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
string code = Request.QueryString["code"] == null || Request.QueryString["code"].ToString() == "" ? "" : Request.QueryString["code"].ToString();
if (code != "")
{
//第二步，获取token
string tokenJson = LoadURLString("https://github.com/login/oauth/access_token?client_id=xxxxxxxxxxxxxxx&client_secret=xxxxxxxxxxxxxxx&code=" + code + "&redirect_uri=http://www.kudsu.xyz/", "post");
JObject jo = (JObject)JsonConvert.DeserializeObject(tokenJson);
tokenJson = jo["access_token"].ToString();
//第三步，获取GitHub用户信息
string userJson = LoadURLString("https://api.github.com/user?access_token=" + tokenJson, "get");
//把GitHub用户信息输出到页面上
Response.Write(userJson);
}
}
}
/// <summary>
/// 请求url
/// </summary>
/// <param name="url">地址</param>
/// <param name="GetPost">post、get</param>
/// <returns></returns>
private string LoadURLString(string url, string GetPost)
{
System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
HttpWebRequest request1 = (HttpWebRequest)WebRequest.Create(url);
request1.Method = GetPost;
request1.ContentType = "application/json";
request1.Accept = "application/json";
request1.Headers.Add("Accept-Language", "zh-cn,zh;q=0.8,en-us;q=0.5,en;q=0.3");
request1.UserAgent = "Mozilla/5.0 (Windows NT 5.2; rv:12.0) Gecko/20100101 Firefox/12.0";
return new StreamReader(((HttpWebResponse)request1.GetResponse()).GetResponseStream(), Encoding.UTF8).ReadToEnd();
}
}
}
