I thought Bqyahoo didn't have a problem in basic functions. I can make me an ugly today. And netizens test BQyahoo, tested the login code I provided (that is, I visited my Yahoo Mail) no problem, then everyone is very interested, she asked to use her own mailbox to try it. The problem has appeared, that is, it is impossible to access her mailbox (an error occurred while accessing).
I have been busy an afternoon, I understand, I am committed to a wrong mistake: I thought that the Yahoo Mail in mainland China was handled by a server.
Think about this impossible, but Yahoo can make an external URL, for multiple servers. This seems to be a load balance. But the fact is not the case.
Finally, by analyzing the web page, it is finally found to find a problem, let different mailboxes go to deal with different servers.
