Express之get,pos请求参数的获取

Express的版本4.X

Get

query参数的获取

url假设:

http://localhost:3000/users/zqzjs?name=zhaoqize&word=cool&job[st]=web

路由的定义:

router.get('/:name', function(req, res, next) {
})

1.获取?name=zhaoqize这样的参数

req.query.name

2.获取&job[st]=web这样的参数

req.query.job.st

3.获取?name=zhaoqize参数的另外一种写法(4.x版本中该方法已被废弃)

req.param('name')

4.获取所有参数

JSON.stringify(req.query)

具体代码:

//http://localhost:3000/users/zqzjs?name=zhaoqize&word=cool&job[st]=web
//http://localhost:3000/users/zqzjs
router.get('/:name', function(req, res, next) {
 //4.版本中已被废弃，不建议使用
 req.param('name')
 console.log(JSON.stringify(req.query) || '')
 //获取get请求参数
 var _html = "Params"+
       "<p><strong>req.params:</strong>"+(JSON.stringify(req.params) || '')+"</p>" +
       "<p><strong>req.params.name:</strong>"+(req.params.name || '')+"</p>" +
       "Query:" +
       "<p><strong>req.query:</strong>"+(JSON.stringify(req.query) || '')+"</p>" +
       "<p><strong>req.query.name:</strong>"+(req.query.name || '')+"</p>" +
       "<p><strong>req.query.word:</strong>"+(req.query.word || '')+"</p>"+
       "<p><strong>req.query.job.st:</strong>"+(req.query.job.st || '')+"</p>" +
       "<p><strong>req.param('name'):</strong>"+(req.param('name') || '')+"</p>" ;
 res.send(_html);
});

结果:

[Get]Params
req.params:{"name":"zqzjs"}
req.params.name:zqzjs
Query:
req.query:{"name":"zhaoqize","word":"cool","job":{"st":"web"}}
req.query.name:zhaoqize
req.query.word:cool
req.query.job.st:web
req.param('name'):zqzjs

Post

post的数据获取

Form Data
 pName:zqz
 pWord:job

1.获取需要的query参数

req.body.pName

具体代码:

router.post('/postTest',function(req, res, next){
  var _html = "[Post]" +
        "<p><strong>req.body:</strong>"+(JSON.stringify(req.body) || '')+"</p>" +
        "<p><strong>req.body.name:</strong>"+(req.body.pName || '')+"</p>" +
