Questions about QQ interconnected documents of Oauth2

there are two modes of OAuth protocol in Tencent QQ Internet platform. The specific process is understood, but the differences in usage scenarios are not clear:

the first is client-s ide mode : using OAuth2"s Implicit_Grant mode

the second is server-s ide mode : using OAuth2"s Authorization_Code mode
