            $('.zy-sec-teacher ul').appendTo(template);
        },
        error: function() {

        }

Code above

This is the chrome browser network display that I successfully requested the data, but the success function was not executed. What is the reason? . . .

This is my project directory, the request address is a json file written by myself, local server
