Facebook重定向Uri没有返回并被困在白页

Question

我尝试让fb sharer发布好，但之后不再返回我的重定向uri url 并坚持这个fb页面

https://web.facebook.com/dialog/return/close?_rdc=1&rdr#=_

这是我的共享代码

<a href="https://www.facebook.com/sharer/sharer.php?app_id=423436984657946&u=<?=$_IM['siteurl'];?>/sview/<?=$qf['url'];?>/<?=$_SESSION['FBID'];?>&picture=<?=$a_img;?>&title=<?=$a_title;?>&description=<?=$a_desc;?>&redirect_uri=<?=$a_return;?>"><button type="button" style="background: blue;border:2px solid blue;" ="" ><i class="fa fa-facebook"></i> শেয়ার করুন</button>                           </a>
