推荐答案

您的AJAX请求'/process_add'将指向您URL的根.例如，abc.com是您的域，此处的终结点为'abc. com/process_add". 确保您的路由器存在于应用程序"/"的根引用中.

Your AJAX request '/process_add' will point to the root of your URL.Say for example abc.com is your domain the endpoint here would be 'abc.com/process_add'. Ensure your router exists in the root reference of '/' in app.Something like this

app.js

var index = require('./routes/index');    
app.use('/',index);

routes/index.js

routes/index.js

    router.post('/process_add', function(req, res, next) {

        var item = {
            name: req.body.name,
            content:req.body.content
        };

        mongo.connect(url, function(err, db) {
            assert.equal(null, err);
            db.collection('data_collection').insertOne(item, function(err, result) {
                assert.equal(null, err);
                console.log('Process added');
                db.close();
            });
        });
    });
