我如何获取Websocket的服务器IP地址

Question

I've created a server using c++ and crow that uses webSockets to communicate with the client (which is an ionic app). I've been do everything through localhost but now I want to deploy the webapp to my iphone and have it communicate with the server. How do I get the URL for the server for the client to use in it's websocket so it can talk to the server?

Answer 1

In most cases when you want to host it for production you would upload it to a hosting provider (eg Azure, AWS, Heroku...).

Once you set up a server with the hosting provider they will provide you with the IP address and/or a URL to connect to the hosted service which you can use in your application.

Answer 2

Well, if your server is like webhost,VPS,CLOUD,or dedicated server, it has static ip address which you can use in your client websocket as the address. Also, the better approach is to point a domain name to the ip address of the server (or host) so that your client can always find the server.

In case you are trying to connect it to your local machine behind a router or modem, then your server might be behind NAT. Find appropriate port-forwarding configuration for your router and forward incoming and outgoing TCP public ports to your local address. then use your public ip address for websocket address ( what is my ip ).

Also, in case your public ip address is dynamic and might change over time, there are services like noip.com that help you create a free domain and use it in your client which helps you find the right ip address all the time.
