最近公司做了个网站，需要用到第三方登录的东西。有QQ第三方登录，微信第三方登录。先把QQ第三方登录的代码列一下吧。
public partial class QQBack : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
Log.Debug("QQ登录", "登录开始");
string app_id = "";
var serializer = new JavaScriptSerializer();
var data = "";
Dictionary<string, string> obj = new Dictionary<string, string>();
//获取 accessToken
string code = Request.QueryString["code"];
if (!string.IsNullOrEmpty(code))
{
string url = string.Format("https://graph.qq.com/oauth2.0/token?grant_type=authorization_code&client_id={0}&client_secret=872660e40efb3b16eecfce835b3ce081&code={1}&state={2}&redirect_uri={3}"
, app_id
, code
, "test"
, "回调地址,还是当前页面地址，以http://www.xxx.com/xxx.aspx 模式，并且对地址进行编码！"); data = Tools.GetPage(url);
Log.Debug("第一个地址：", data);
string accessToken = "";
string[] array_access_token = data.Split('&');
if (array_access_token != null && array_access_token.Length > )
{
for (int i = ; i < array_access_token.Length; i++)
{
if (!string.IsNullOrEmpty(array_access_token[i]))
{
string[] keyValue = array_access_token[i].Split('='); if (keyValue != null && keyValue.Length > )
{
if (keyValue[] == "access_token")
{
accessToken = keyValue[];
}
}
}
}
} //获取OpenID
string url2 = "https://graph.qq.com/oauth2.0/me?access_token=" + accessToken;
data = Tools.GetPage(url2);
Log.Debug("第二个地址：", data);
data = data.Replace("callback(", "").Replace(");", "");
obj = serializer.Deserialize<Dictionary<string, string>>(data);
string openid;
if (!obj.TryGetValue("openid", out openid))
return; string url3 = string.Format("https://graph.qq.com/user/get_user_info?access_token={0}&oauth_consumer_key={1}&openid={2}", accessToken, app_id, openid); data = Tools.GetPage(url3);
Log.Debug("第三个地址：", data);
var userInfo = serializer.Deserialize<Dictionary<string, string>>(data); if (openid != null && userInfo["nickname"] != null)
{
Users _MTUsers = GetModel( openid); //获取用户信息 if (_MTUsers == null)
{
Insert(_MTUsers); //如果不存在，创建
}
else
{
_MTUsers.LastLogin = DateTime.Now;
_MTUsers.LastUpdated = DateTime.Now;
Instance.MTUsers.Business.Update(_MTUsers); //存在则修改
}
Session["CurrentUser"] = _MTUsers; //将当前登录的用户放入session中
Log.Debug("QQ登录", "执行页面跳转成功");
}
}
Log.Debug("QQ登录", "登录结束");
}
}
