Answer 1

redirect之后就不要send了

router.post('/login',function(req,res){
    
    var query = require('../modules/database');
    query("select * from managers where ManagerID =10001",function(err,vals,fields){ 
          
          if(req.body.password==="admin")
        {
        res.redirect('/home');
        return; ///这里加个return
        }
        res.send('ID或密码错误!');

    });
    
});
