Ajax cross-domain request issues

Ajax is not allowed cross-domain requests, today when using bootstap-table, Data-url Use the address is an absolute address, rather than a relative address, so when loading data in error.

Use is http://127.0.0.1 when starting, and it is not allowed to use address http://localhost when requested.

Therefore, use the relative address rather than the absolute address when using AJAX later.

There are a lot of difficulties in finding this problem, and if I start to call Ajax and fail, maybe I can quickly realize that it is an AJAX cross-domain problem. But because you use a control that someone else has written, the interior is encapsulated, so you can't quickly locate the problem. I used the JS debugging tool to track the bootstrap-table internal debugging before I finally realized the problem.

This is the disadvantage of using the control, the control can simplify the work, but when encountering a problem, if it is written in the language, we can use the language itself to solve the problem of the rules. The encapsulation of controls prevents us from being aware of problems quickly.
