您需要记住的是,只要帐户被授权通过Facebook链接,帐户才会被链接.您应该做的是在数据库中维护第二个链接帐户表,以便您知道谁是谁以及他们是否与Facebook链接.

您应该阅读此集成注释,它提供了许多有用的信息.

它并没有真正说明如何做事,但它确保你勾选你应该做的事情.

即：

Sign Up should fail if the user denies
permission to the app (category: sign
up)

Since we need access to an email
address,Sign Up should fail if the
user provides publish permission but
denies email permission (category:
sign up)

If the user provides an email address
that already exists in your system,
fail Sign Up. Make sure no YouFace
backend tables are modified (category:
sign up,1:1 mapping) PS – when this
happens,I didn’t find a way for you
to de-authorize YouFace on the
Facebook user’s behalf. The user must
manually do this if they wish you use
the same account but provide a
different email address.

Accounts created using Facebook
Connect should not be able to login
using YouFace’s default email/password
login system (category: sign in,
account security). PS: Since YouFace
accounts require a password and those
created using Facebook Connect don’t,
make sure to insert a random password
hash into your table to avoid silly
errors

Accounts created using YouFace should
be able to sign in without requiring
to be signed into Facebook,even if
when a link to a Facebook accounts
exists (category: sign in)
