找不到404 /服务器-Node.js Ajax

Question

i am trying to send data from app.js to nodejs server.js but AJAX is giving error POST http://localhost:9615/server 404 (Not Found)

When I open http://localhost:9615/server on browser it work fine and show desired output that is callback('{"msg": "OK"}')

Here is app.js code

I have also tried url: 'server' and '/server'

       $.ajax({
            url: 'http://localhost:9615/server',
            // dataType: "jsonp",
            data: '{"idToken": '+idToken+'}',
            type: 'POST',
            jsonpCallback: 'callback', 
            success: function (data) {
                var ret = jQuery.parseJSON(data);
                console.log('Success: '+ret.msg);
            },
            error: function (xhr, status, error) {
                console.log('Error: ' + error.message);

            },
        });

Here is server.js code

app.get('/server', function(req,res, next){
    console.log('Request received: ');
    util.log(util.inspect(req)) 
    util.log('Request recieved: \nmethod: ' + req.method + '\nurl: ' + req.url) // this line logs just the method and url

    res.writeHead(200, { 'Content-Type': 'text/plain' });
    req.on('data', function (chunk) {
        console.log('GOT DATA!');
    });
    res.end('callback(\'{\"msg\": \"OK\"}\')');
 });

Answer 1

You are trying to POST something on a GET endpoint.

Change to post

app.post('/server', function(req,res, next){
    console.log('Request received: ');
    util.log(util.inspect(req)) 
    util.log('Request recieved: \nmethod: ' + req.method + '\nurl: ' + req.url) // this line logs just the method and url

    res.writeHead(200, { 'Content-Type': 'text/plain' });
    req.on('data', function (chunk) {
        console.log('GOT DATA!');
    });
    res.end('callback(\'{\"msg\": \"OK\"}\')');
 });

Answer 2

because when you do ' http://localhost:9615/server ' in browser its a get request

& The one you are trying in code is post request.

Change either one as per your use .!
