Very painful csdn verification code. Updated csdn.

I also encountered this problem two days ago. I have tried it dozens of times, and the csdn verification code is always wrong.

Attempt to clear IE cache is invalid;

Later, some people said that it might be caused by the inconsistency between computer time and standard internet time. It happened that the time on my computer was 10 minutes faster than the standard Beijing time, so I logged in CSDN. Before the time was out of sync, I tried several times, and the verification code was wrong (in fact, I clearly entered it correctly), so I synchronized the computer time with the online time, logged in again, and logged in successfully.

Confirm that the computer time is inconsistent with the standard online time. It is recommended to synchronize the time and try again.
