Why is there always an error in the verification code entered when applying for Taobao account?

The first case: the problem of refreshing the page.

The login verification code will also change every time the page is refreshed. If you are prompted that the verification code is wrong, the system will change the verification code. At this point, the previous verification code may still be displayed on the page. After the page is loaded, you need to change the new verification code, and then enter it according to the verification code.

The second case: the full/half angle problem of input method.

The digital state of input method is different. That is, the full angle is 1234 and the half angle is 1234, which is different. General webpage verification code only supports half-width digits.
