javaweb项目为什么要把localhost拦截，必须要127.0.0.1访问？

Question

有什么不同吗？为什么要拦截localhost

Answer 1

127.0.0.1 is the loopback address, referring to the local machine.

The reason why you can use localhost to access the local area is that the localhost domain name is pointed to 127.0.0.1 in the system's host file, so please check whether the system host file configuration is correct.

Answer 2

This situation occurs when Ajax cross-domain requests are made.

Answer 3

Because I can change the mapping of 127.0.0.1 in the host file to zhouxingchi
