阅读ajax发布后遇到问题

Question

I am working on a website and I am trying to connect JavaScript and php using ajax. I have a problem with reading ajax response.

I have one php script which has the following code:

<?php
echo "1";

And a function written in JavaScript ecma 6, which has the following code:

loginUser(username, password) {
        return new Promise((resolve, reject) => {

            var request = require('ajax-request');
            request.post(
                {
                    url: 'http://swiftservice.psoftwarestudio.com/Admin.php',
                    data: {
                        username: username,
                        password: password
                    },
                    headers: {}
                }
                , (data) => {
                    resolve(data);
                }
            );
        });
    }

When I debug, the data is always null. I am very new at web programming especially whit ajax. I hope someone can point me to the error, thanks.

Answer 1

I looked in the documentation of the ajax-request module and noticed that the callback takes 3 arguments: function(err, res, body) { .

Perhaps the required data is in the third?

You need to parse the data you get back from your AJAX call into a JSON Object, as what you get is the String representation of it:

loginUser(username, password) {
        return new Promise((resolve, reject) => {

            var request = require('ajax-request');
            request.post(
                {
                    url: 'http://swiftservice.psoftwarestudio.com/Admin.php',
                    data: {
                        username: username,
                        password: password
                    },
                    headers: {}
                }
                , (data) => {
                    resolve(JSON.parse(data));
                }
            );
        });
    }
