AJAX 对节点 JS 服务器的 POST 请求无法从 IPAD 或 IPHONE 工作

Question

I have an Apache server running with a website on Windows 10 OS. On button click on the website I make an AJAX POST request to an Express server in Node JS to run some code and return a JSON string. This works fine on my Windows 10 OS.

When I click the button on the website on my IPAD or IPHONE nothing happens. In the command prompt I see no console log of anything reaching the Express server.

Conditions:

• Firewall on Windows 10 OS configured to allow incoming data on port 80 and 443 (Apache) and 8000 (Express).
• On the IPAD and IPHONE cookies deleted and "Do not allow following" unchecked.
• All on the same LAN.

What am I missing here? (next, some code) Express Server JS

 var express = require('express'); var path = require('path'); var app = express(); var cors = require("cors"); var bodyParser = require('body-parser'); const port = 8000; app.use(bodyParser.json()); app.use(cors()); app.post('/FileName', function (req, res) { var Fname = req.body.fname; console.log("received filename: " + Fname); // Require the module var EasyFit = require('./dist/easy-fit.js').default; // Read a.FIT file var fs = require('fs'); fs.readFile('C:/xampp/htdocs/ATP/FIT/' + Fname + '', function (err, content) { // Create a EasyFit instance (options argument is optional) var easyFit = new EasyFit({ force: true, speedUnit: 'km/h', lengthUnit: 'km', temperatureUnit: 'celcius', elapsedRecordField: true, mode: 'list', }); // Parse your file easyFit.parse(content, function (error, data) { // Handle result of parse method if (error) { console.log(error); } else { //res.send(JSON.stringify(data)); res.send(data); console.log('Parse ok'); } }); }); }) app.listen(port, '0.0.0.0'); console.log(`FIT app listening at http://localhost:${port}`);

AJAX Request JS on client side

 $.ajax({ cache: false, url: 'http://localhost:8000/FileName', type: 'POST', contentType: "application/json", data: JSON.stringify(data), success: function(result) { console.log('received fit in JSON'); console.log(result); });

Answer 1

You can find out your ip address using a command like this:

ipconfig|findstr IPv4

Then substitute that for localhost

So you will have a line like

url: 'http://192.168.1.131:8000/FileName',

instead of the one that says localhost:8000

After turning off my firewall it worked like a charme. Found the answer in the following post.

Allowed the node.js app to go through my firewall. It works perfectly!
