Vue设置全局变量，所有页面都可以调用和修改

1、定义一个变量variables.js
export default {
    hospitalCode: '',
    navTitle: '',
    accessToken: '',
    expires: '',
    statusCode: '',
    depListCode: '',
    patientTypeCode: ''
}

2、在main.js中引入variables.js
import variables from "@/api/variables";
global.variables = variables;

3、变量调用
variables.hospitalCode
