7.5 nodejs笔记

//获取静态资源

app.use(express.static('./public'));

 

express定义路由的三种方式。http://www.jikexueyuan.com/course/1722_2.html

1、//path

app.get('/',function (req,res) {

    res.end(

        'hello worl0d \n'

    )

})

 

2、//Router

var Router=express.Router();

/*

http://example.com/post/add

         http://example.com/post/lst

 

*/

Router.get('/add',function (req,res) {

    res.end('ROuter/add\n');

})

Router.get('/list',function (req,res) {

    res.end('router/list\n');

})

app.use('/post',Router);

 

3、route

 

app.route('/article')

    .get(function (req,res) {

       res.end('route/article get\n')

    })

    .post(function (req,res) {

        res.end('route/artcle post\n')

    });

 

运行：curl -X POST http://localhost:3000/article

           curl -X GET http://localhost:3000/article

 

//http://example.com/news/344

//获取344

app.param('newsIdd',function (req,res,next,newids) {

    req.idd=newids;

    next();

});

app.get('/news/:newsIdd',function (req,res) {

    res.end(req.idd+'\n s');

})
