微信分享域名配置问题

[wufangjian]

请教一下, 在做微信分享的过程遇到的路由问题。 怎样才能通过 http://www.xxxx.com/MP_verify_aaaaaaaaaa.txt 该链接访问到 MP_verify_aaaaaaaaaa.txt资源?

通过配置中间件插件（静态化）可以吗？这样做是否合理

module.exports.static = function(app, conf){
    return function(){
        app.use(conf.urlPattern, yog.express.static(conf.staticPath, conf.options));
        app.use('/MP_verify_aaaaaaaaaa.txt', yog.express.static(yog.ROOT_PATH + '/MP_verify_aaaaaaaaaa.txt', conf.options));
        //拦截404
        app.use(conf.urlPattern, conf.notFound);        
    };
};

module.exports.static.defaultConf = {
    options: {
        maxAge: 0
    },
    staticPath: yog.ROOT_PATH + '/static',
    urlPattern: '/static',
    notFound: function(req, res){
        res.status(404);
        res.send('404: Resource not Found');
    }
};
