使命:要从我的网站成功登录Facebook,返回用户ID,最后发送电子邮件等,以添加到我的数据库数据库。
我从developers.facebook.com下载了最新的4.0.0 SKD PHP并将其上传到我的文件管理器。
我正在使用GitHub上的代码:http://packetcode.com/rd/6e20a9
请参阅index.php

我已经复制了视频教程,当它这样做时它会起作用所以我迷失了我的错误。
当我点击“使用Facebook登录”链接时,它将我带到了Facebook,在我点击“立即播放”时请求了许可,然后将其重定向回我的网址,但是出现以下错误。
现在,每当我点击“登录facebook”链接时,我都会直接看到错误..
Fatal error: Uncaught exception 'Facebook\FacebookAuthorizationException' with message 'Error validating verification code. Please make sure your redirect_uri is identical to the one you used in the OAuth dialog request' in /home/*****/public_html/lib/Facebook/FacebookRequestException.php:104 Stack trace: #0 /home/*****/public_html/lib/Facebook/FacebookRequest.php(268): Facebook\FacebookRequestException::create('{"error":{"mess...', Object(stdClass), 400) #1 /home/****/public_html/lib/Facebook/FacebookRedirectLoginHelper.php(146): Facebook\FacebookRequest->execute() #2 /home/*****/public_html/index.php(48): Facebook\FacebookRedirectLoginHelper->getSessionFromRedirect() #3 {main} thrown in /home/*****/public_html/lib/Facebook/FacebookRequestException.php on line 104
在这里和谷歌看后,我似乎无法找出导致此错误的原因以及如何解决此问题。
