使用mongoosejs链接Mongodb

var options={
  user:‘test_user‘,
  pass:‘123456‘
};
mongoose.connect(‘mongodb://127.0.0.1/test‘,options);
var User = mongoose.model(‘User‘, { name: String ,des:String});

app.get("/",function(req,res){
  User.find({},function(err,users){
    console.info(err);
    res.render("user",{users:users})
  });
});

var initCount=0;
app.get("/add",function(req,res){
  var user = new User({name:‘user‘+(initCount++)});
  user.save();
  res.redirect("/");
});
