The following is the method of obtaining token written under system/core/common.php. In fact, it needs to be salted, otherwise disgusting people will do disgusting things.

I won’t write about the previous menu management, it’s just to manage the data in that table and make sure that there is no problem with the data in the data table.

Only need

in the controller

$this->load->library("Makemenu");

Then call $this->makemenu->dolist();

will be pushed to the WeChat server. You also need to pay attention to defining two constants APPID and APPSECRET in the entry file.

I released it for everyone, I hope it will be useful, and I will make a backup copy for myself.
