Question

我有一个名为推荐书的社交网络，我使用Facebook和Google Plus登录按钮在用户第一次点击按钮时注册用户，并在第二次点击按钮时记录用户。有一天，我正在和一个女孩交谈并向她展示我的网站，我尝试使用facebook登录按钮在我的网站上注册她，系统将她登录到另一个用户的帐户，而不是注册她。现在我几乎可以肯定这是来自facebook的一个错误，使facebook系统返回来自另一个人的电子邮件，我想知道是否所有facebook登录按钮的问题都记录了错误帐户中的用户。所以我正在粘贴准确的代码，移动版本，我想问这个代码是否有任何问题，这是有效的，这可能使facebook系统从试图登录的用户返回另一个用户的电子邮件？这是一个问题，所有Facebook登录按钮记录用户在错误的帐户？

<script type="text/javascript"> 
<!--

$(document).ready(function(){

	$(".SpinnerTR").hide();

});

function myTrim(x) {
	return x.replace(/^\s+|\s+$/gm,'');
}

function setCookiesRB(id) {
	var date = new Date();
	date.setTime(date.getTime() + (365 * 24 * 60 * 60 * 1000));

	var url = "http://localhost:8989/Login.jsp";

	if(url.toLowerCase().indexOf("localhost:8989") >= 0) {
		document.cookie = "IsRecommenderLogged=Yes; expires="+date.toGMTString()+"";
		document.cookie = "RecommenderId="+id+"; expires="+date.toGMTString()+"";
	} else {
		document.cookie = "IsRecommenderLogged=Yes; expires="+date.toGMTString()+"; domain=recommendationbook.com;path=/";
		document.cookie = "RecommenderId="+id+"; expires="+date.toGMTString()+"; domain=recommendationbook.com;path=/";

Answer 1

我发现了错误。它就在我身边。如果用户成功登录，我认为facebook总是会返回一封电子邮件。但是登录facebook登录按钮的用户可以拒绝许可，然后facebook系统将返回垃圾或通用的Facebook电子邮件。我的一个用户注册了，因为我没有检查我把垃圾facebook放回电子邮件的地方，我没有注意到。后来，当我试图注册这个女孩时，我提到facebook系统返回了同样的垃圾，这就是为什么她登录了另一个女孩的帐户。要修复我在javascript中放置了以下条件：

＆＃13;

var emailRegex = new RegExp("^([a-zA-Z0-9_.-]+)@([a-z0-9_.-]+)$");

if(!emailRegex.test(email) || email.toLowerCase().indexOf("facebook.com") >= 0) { }

＆＃13;

Facebook登录按钮有时检索错误的用户电子邮件
