如何在本地访问 Node.JS 项目？

Question

I have a node.js project running on the ubuntu server.---> App is listening on 5000.

So, I want to access it locally. Like http://server_ip:5000

How can I do this?

Answer 1

First, you need to know the IP of your server. You can do it by using an ifconfig (look for interfaces like ethX , enpXsY , enoX where X and Y are numbers) or curl icanhazip.com command. I would recommend to execute both of them and see if the IPs in the output match. If they don't - your server might be located behind NAT and you won't be able to access it unless you forward ports on your NAT host which is outside of the scope of this question.

Another thing you need to keep in mind is that servers can be protected by firewalls. The procedure of adding port 5000 to the allowlist varies for every firewall. sudo ufw allow 5000 can often do the trick on Ubuntu (but, once again, it may or may not work - for you this procedure can be different).

After this you should be able to access your server by typing http://<YOUR_SERVER_IP>:5000 in your browser address bar

Answer 2

You need to get the IP of your computer (IPv4). Here's a link to a webpage that shows it to you https://www.whatismyip.com . After this you can simply type in your IP and then add :<port> , so in your case :5000

Answer 3

For access from the same machine use http://localhost:5000 or use hostname eg http://hostname:5000. Get hostname by writing hostname command from the terminal.

For access from other machines such as your mobile device or laptop, they all need to be connected to the same network, lets say all connected to the same WiFi network. In this case use the IP address of the machine that is running your server. Lets say if your IP is 192.168.1.1 then for eg write this http://192.168.1.1:5000

Use ifconfig for getting IP address.
