调用:index.js

const api = require("../../api.js")
Page({
    onShow: function() {
        this.getStudentInfo(openid)
    },
    getStudentInfo(openid){
        let _this = this;
        api.getStudentInfo(openid).then(res => {
            if(res.code === 0 && res.data){
                ...
            }
        })
    },
})
