Lookin for a windows Internet check

Question

I'm building a small app to use offline with my business so i can cut back on paperwork. would like to be able to sent data to a server and then be able to print a hard copy of that data once processed and broken down.

I'm looking for a simple check solution for internet connectivity. it will be for windows only and is used to change the color of an image and wheather to store data or send it once. i think I have to do my store to script data in the offline callback plus a set synced bool to false. Then the check if (synced == false) in the online callback. if false during online callback then send stored data to backend and set it to synced = true; (basically making it fire only once)

I'd also have a sync button to do that similar call to update server manually. If in offline mode:prompt a warning window. If online mode: update the server data.

Is this worded well enough? I'm out of practice with this LOL.

Anyway, Network.player.ipAddress; is depricated and I'm not looking for an android enum check or Google ping solution that i keep seeing on here. Is there any other way within unity's code to check this?? @Bunny83 always has best answers for situations i need, so if you are not busy I'd super appreciate a small amount of help

Answer 1

Well, first of all the "internet" isn't a single thing you connect to. The internet is the sum of the international network infrastructure run by countless of decentral and individual companies. It just works like the road / street network. Pretty much every house is connected to the street infrastructure (since it's usually built next to a street). Just being physically connected to the network, does not guarantee that you can reach a certain end point. There are essentially 3 things that have to work out well in order to get from point A to point B.

First it's your own ability to "leave" your house. If your front door is locked or blocked you can't even enter the street. This would be the same as the plain physical connectivity to the "internet".

The next obstacle would be any issues you might encounter while moving on the street network. There might be an accident, closed road, traffic jam. Usually you can take a detour to move around such obstacles but that might not always be the case. So temporarily you might be cut off of certain parts of a city, even though you can enter the street network and move to various places, just not the one you wanted to reach.

The last issue might be at your destination. So the network is fine, but your target location has an issue. For example you wanted to go to the local library, but it's currently closed. So you can reach your destination, but it's out of service / not responding.

When it comes to checking the "connectivity to the internet" you should ask yourself what information you're actually interested in. Just the fact that you have wifi connectivity or a direct connection to an ISP does not guarantee that you can reach your target. Checking if you can reach another public service / server like google.com for example only tells you that you can reach google, but does not necessarily mean you can reach your own server. So all those "tests" that many people recommend are pretty pointless. Of course you could assume that if you can reach google.com, that you can also reach yourServer.com, but that's not really a reliable way of testing if you can reach a certain service on your server.

So the only real solution in such a case is to actually contact your own service / server. This clears all 3 questions at once. Just put a simple php script or resourcce on your server that you can query from your client. If you can access it successfully, you can reach your server. How you actually reach it doesn't matter.

Of course in case your probing request to your server fails you can take additional actions to provide the user with more insight. For example if the connection to your server fails there are generally two cases you might want to distinguish: Either your own server is not reachable (your server's fault or maybe a temporary issue with that route / internet) or the user might have no connection to the internet at all. To distinguish those two cases you could simply check several other public endpoints on the internet. So if none are reachable, the user probably isn't connected to the internet at all. If some are reachable but your server isn't, it's just an issue with your server (maintenance?).

So if you can reach your server, just do your business as normal. If your server isn't reachable but other servers are reachable, you might want to inform the user that your service might be down for maintenence and he should try it again later. In case none of your testing URLs are working you might want to inform the user to check the internet connectivity.

So keep in mind, first check if you can reach your own server. Only in case that fails you might want to check other testing URLs to see if the user can reach anything else on the net.

ps: Please also keep in mind that most public services (like google) have quite strict terms of services when it comes to automated uses of their services. So be careful what other testing URLs you're using. Of course if you just want to tell if your server is reachable or not, just requesting your own test resource from your server would be enough.
