I have seen other questions with the same error, but none of the answers seem to work.

<!DOCTYPE html>

<html>

<body>



<form action=http://127.0.0.1:8080/del method=post>

  First name: <input type=text name=fname><br>

  Last name: <input type=text name=lname><br>

  <input type=submit value=Submit>

</form>



<p>Click on the submit button, and the input will be sent to a page on the server called http://127.0.0.1:8080/del.</p>



</body>

</html>

server.js

var express=require('express');

var body_parser=require('body-parser');

var request = require('request').defaults({json:true});

var app=express();

var del=require('./del'); 

app.post('./del',del.test);

var server = app.listen(8080,function(){

    var host=127.0.0.1;

    var port=8080;

    console.log(App is listening at http://%s:%sn,host,port);

});

del.js

module.exports={

    test: function(){

        console.log(Hello world.);

    }

};

Each time, when I submit the form, it shows

Cannot POST /del

In your server.js change this line:

app.post('./del',del.test);

to this:

app.post('/del',del.test);

then you have correct router.

And your del.js change to this:

module.exports={

    test: function(req, res){

        console.log(Hello world.);

        res.status(200).end();

    }

};

because router function should return response.
