When I use qq and wechat to log in to the third party, there will be two accounts; At this point, when I bind the qq account and bind wechat, it will prompt that wechat has been bound and binding will fail. At this point, when I killed the application process and re-logged in with qq, I was prompted to bind successfully. However, it does not appear on the server, only the verified data cache is poured to the local, resulting in the need to pull data from the server again
