Twitter API通过用户的邮件ID搜索用户

Question

I was developing an application and I was wondering whether there is any way to search a particular user by his/her mail id. I came to know that twitter once gave such API's but later on withdrew them taking into consideration security issues. So is there any method by which I can search a user via the registered email id ?

Answer 2

According to this discussion on Twitter Developers , the username and the user's e-mail are two totally different things. The following quote was written by a Twitter Technician ( @episod ) in the discussion :

Both Facebook and Google are predicated on actual identity -- email address makes a lot of sense there. Twitter is less firmly attached to real-world identity -- once could say the email address associated with an account is more of a formality than anything else, not a piece of information that's necessarily attached to the identity of the account or its owner.

So it seems that you won't be able to retrieve a username through the Twitter API with the user's e-mail. The only thing to do is sending an e-mail to the user in order to ask him (or her) its Twitter username.
