我们可以在 Express.js 的路由中使用另一个路由吗？

Question

So I have index.js, userRoute, and friendRoute

in index.js

const app = express()
const userRoutes = require('./routes/user')
app.use('/users', userRoutes)

in /routes/user.js, I want to append /friends routes

const friendRoutes = require('../routes/friend')
router.use('/:username/friends', friendRoutes)

The expected result that I want is get the user's list of friends /users/:username/friends

But I didn't get the username params when I tried to hit the url Is there any way to achieve the expected result? or is there best practice of doing this kind of stuff?

Answer 1

exports.friendRoutes = async (req, res)=>{
    const username = req.params.username;
    console.log(username)
}

// or

exports.friendRoutes = async (req, res)=>{
    const {username} = req.params;
    console.log(username)
}

Answer 2

Update your /routes/user.js

 const friendRoutes = require('../routes/friend') router.use('/:username/friends', (req, res, next) => { req.username = req.params.username; next(); }, friendRoutes);

Use req.username in your /routes/friend.js to get the params value
