企业故障：QQ好友转发网站链接出现404

48468人浏览 / 1144人评论

一、有同事反映www.linagzeyu.com网站通过qq端转发链接给好友时，对方打开报404;

二、点击QQ转发的网址进行访问出现，在末尾会自动添加了某些参数，导致404.检查链接后缀携带？tdsourcetag=s_pctim_aiomsg

三、检查网站dns发现，https://www.liangzeyu.cn/gallery/wzl/upack/201903/t20190314_910891.html?tdsourcetag=s_pctim_aiomsg通过qq打开的链接，后缀增加了?tdsourcetag=s_pctim_aiomsg

四、最后添加if语句恢复正常

if ( $query_string ~ "^open_source=weibo_search$") { set $keyword PASS;}
