express 怎么对以下代码进行简写

Question

//登录app.get(`/business-login`,function(req,res){if(!app.locals.isLogin){res.redirect('/')}res.render(`business-login.html`);});//申请入驻app.get(`/business-apply`,function(req,res){if(!app.locals.isLogin){res.redirect('/')}res.render(`business-apply.html`);});//审核中app.get(`/business-review`,function(req,res){if(!app.locals.isLogin){res.redirect('/')}res.render(`business-review.html`);});上面写了三个在判断是否登录的，如何进行简写啊？

Answer 1

functionisLogin(req,res,next){
if(!app.locals.isLogin){
res.redirect('/')
}else{
next()
}
}
//登录
app.get(`/business-login`,isLogin,function(req,res){
res.render(`business-login.html`);
});
//申请入驻
app.get(`/business-apply`,isLogin,function(req,res){
res.render(`business-apply.html`);
});
//审核中
app.get(`/business-review`,isLogin,function(req,res){
res.render(`business-review.html`);
});
                            

Answer 2

app.get('/business-(login|apply|review)',function(req,res){
if(!app.locals.isLogin){
res.redirect('/')
}
res.render(req.originalUrl.substring(1)+'.html');
});
