express request query vs body vs params

app.get('test/:id/:name', (req, res) => {

      // test/10/jay?age=25&email=abc@abc.com

// req.params => { id : '10' , name : 'jay' }

// req.query => { age : '25' , email : 'abc@abc.com' }

});

post body 값에 { "id" : "10" , "name" : "jay" }

app.post('test', (req, res) => {

//req.body => { id : '10' , name : 'jay' }

});
