router.post('/goods/tejia',function(req,res,next){
var gid = req.body.gid; console.log(gid);
User.find({ gid :gid }).then(function(goodsInfo){
console.log(goodsInfo); return goodsInfo.save();
}) })
router.get('/',function(req,res,next){ // console.log(req.goodsInfo); res.render('goods',{ goodsInfo:req.goodsInfo }) })

ejs,jade,自行百度

这是一个异步执行顺序的问题。你要确保你拿到数据的值之后，再执行res.render。
我用了一个jas的插件来控制执行顺序。你可以看看我这个笔记。保障Node服务器稳定运行的几点经验 http://note.youdao.com/noteshare?id=db6aae9bbabb64cff9215cd12e138e8f&sub=3BE58C1F915E4BE89DD14EA8F1BED8D9
