Request

Properties

• headers

• params

• query

• body

• cookies

Tips

• If you want your app to be faster, please consider using schemas

• If you do not use these properties, especially body, your app will response faster, because these properties parse takes time

• req.originalUrl, req.baseUrl is not the same as express properties, just alias to req.url

Examples

Headers example

app.get('/secret', (req) => {
  const { authorization } = req.headers;
});

Params example

app.get('/user/:id/login', async (req) => {
  const { id } = req.params;

  const result = await db.getUser(id);

  // do something...
});

Query example

// /user?token=123
app.get('/user', async (req) => {
  const { token } = req.query;

  const result = await jwt.verifyToken(token);

  // do something...
});

Body example

app.post('/user', async (req) => {
  const { username, password } = req.body;

  // You can use db.createUser(req.body), but this may cause side-effects
  const result = await db.createUser({ username, password });

  // do something...
});

Cookies example

app.post('/user', async (req) => {
  const { userId } = req.cookies;

  // You can use db.createUser(req.body), but this may cause side-effects
  const isUserLoggedIn = await dbHelper.checkUser(userId);

  // do something...
});

Get IP example

app.get('/api/ip',(req,res) => {
    res.send({
        ip: req.getIP(),
        proxiedIP: req.getProxiedIP() // for use in production behind a reverse proxy
    });
});
