accept parameter express code example
Example 1: express get params after ?
GET /something?color1=red&color2=blue
app.get('/something', (req, res) => {
req.query.color1 === 'red' // true
req.query.color2 === 'blue' // true
})
Example 2: express url redirect
const app = require('express')();
// The `res.redirect()` function sends back an HTTP 302 by default.
// When an HTTP client receives a response with status 302, it will send
// an HTTP request to the URL in the response, in this case `/to`
app.get('/from', (req, res) => {
res.redirect('/to');
});
app.get('/to', (req, res) => res.send('Hello, World!'));
