FB login error:Invalid redirect_uri
當FB login功能出現這個訊息：
{
"error": {
"message": "Invalid redirect_uri: \u61c9....",
"type": "OAuthException",
"code": 191
}
}
因為FB app限制redirect的ip或url，程式裡指定的redirect uri，必須符合fb app設定的資料，所以設定以下兩者之一，才能正常運作：
1.settings-basic-Site URL
2.settings-advanced-Security-Valid OAuth redirect URIs
