Target Https Request

It's the login request:

  • JP:
https://game.fate-go.jp/login/top?_userId=xxxx
  • NA:
https://game.fate-go.us/login/top?_userId=xxxx
  • CN: where line3-s2-ios-fate may change, the key point is _key=toplogin
https://line3-s2-ios-fate.bilibiligame.net/rongame_beta//rgfate/60_1001/ac.php?_userId=xxxx&_key=toplogin
  • TW: similar with CN, but its domain is https://line3-s1-all.fate-go.com.tw
