Create a Jade template files named "index.jade" in the views directory, with the following content.

html  head    title!= title  body    h1!= message

Then create a route to render the "index.jade" file.

app.get('/',function(req, res){  res.render('index',{ title:'Hey', message:'Hello there!'});})

On making a request to the home page, "index.jade" will be rendered as HTML.

服务端返回网页，不如返回值，客户端判断符合条件，然后跳转本地的html

2.不显示_id字段，显示需要的字段

> db.node_book.find({},{"book_name":1,"author":1,_id:0})

3.查找某个条件的数据

> db.node_book.find({"book_name":"123"},{"book_name":1,"author":1,_id:0})

db.node_book.find({"book_name":"123","author" : "mfy1"},{"book_name":1,"author":1,_id:0})

插入数据

db.node_book.insert({"book_name":"123", "author" : "mfy"})

db.node_book.insert({"book_name":"123", "author" : "mfy1"})

db.node_book.insert({"book_name":"1234", "author" : "mfy1"})

在node的查询代码也可以类似用

4.数据库操作的2个文件放在
