Answer 1

Dont use database name in connection url:

const mongo_url = 'mongodb://localhost:27017'

Instead use below method:

MongoClient.connect(mongo_url , { useNewUrlParser: true }, (err, client) => {
        if (err) return console.log(err)
        const  db =  client.db('student')
        const collection = db.collection('test_student');
        console.log(req.body);
        collection.insertOne(req.body,(err,result)=>{
            if(err){
                res.json(err);
            }
            res.json(result);
        });
    });
