Would someone mind sharing their update check code?

As I saw albo1125's update code and it looks real nice it is just I couldn't find any function inside the LSPDFR API class to do the update checking with(as I thought it was apart of the LSPDFR api now).

As I read awhile back cyan was going to implement this so you could just use your listing here on lcpdfr.com and use json or something to return the latest version and tell the person that there is a update available although I am unable to find that at this time....so would someone else mind helping me out?

Cyan did indeed post it:

You can now query the following URL:

http://www.lcpdfr.com/applications/downloadsng/interface/api.php?do=checkForUpdates&fileId=8082
And it will return a JSON object with version and pageUrl. Version will equal to the current version of the file, exactly as specified in the file manager. pageUrl will equal the URL to the file's page on LCPDFR.com.
If you just want a text string with the latest version, you can call the following URL instead:
http://www.lcpdfr.com/applications/downloadsng/interface/api.php?do=checkForUpdates&fileId=8082&textOnly=1
Note that there may be up to a 30 minute delay between updating the file and the above showing the new version, due to caching.

If anyone else wants to use this, you just have to change the fileId to the ID of the file. You can determine your file ID by the URL of your file. e.g.:
http://www.lcpdfr.com/files/file/8082-code-3-callouts/
The file ID in this case would be 8082.

 

 

I use this in my Main.cs, and then call it during OnOnDutyStateChanged.

It uses an .ini file to store the preference for whether automatic update checking is enabled, and when the last update check is done. As below, it won't check for updates more frequently than once per day and waits a random interval between 7.5 and 45 seconds before trying to do the check.

This isn't in the released version of my plugin yet, and it's only been lightly tested, so use it "as is", with no promises made! :)

It also uses calls to my internal "DumpLog" wrapper function that your code won't have (it essentially just writes to Game.LogTrivial, but dumps various other things as well). You'll need to make changes to each one of those logging references!

Removed my plugin's fileId from the URL string -- you need to put yours in there instead!

An update to my update checking mechanism. Now I run the actual HTTP requests inside a non-GameFiber Thread, which means the game doesn't drop frames while we wait for the HTTP response.
