推荐答案

how to check case sensitive username

用户名字段通常不区分大小写.

Username fields are generally case insensitive.

how to check case sensitive password

密码字段通常区分大小写.这是什么问题?

无论哪种情况，如果您需要从一般角度出发，在比较时都需要注意.如果要使用不区分大小写的密码，请将其转换为toUpper或toLower并进行存储/比较.与用户名相同.

Password fields are generally case-sensitive. What is the issue here?

In either case, if you need to go other way from general, while comparing you need to take care. If you want case-insensitive passwords then convert it into toUpper or toLower and store it/compare it. Same with username.
