Server.callWithGET

[Lindon]

@DanH whats in response if the file is missing?

[Matt_SF]

@DanH I'm not in front of my computer, but wouldn't it work if you use

if(response != "") 

// or

if(response != undefined) 

And then check the version number...?

[DanH]

@Matt_SF @Lindon Thanks both, will try these....

[DanH]

@Matt_SF @Lindon not having any joy with those - perhaps I'm using them wrong? Currently the if(response != undefined) executes every time. The response is a 'file does not exist' error generated by the server...

function VersionCheck()
{
	
	Server.setBaseURL("https://");	
	Server.callWithGET("coolfile.json", VV, function(status, response) {

	if(response != undefined) 
	{
		Console.print("it's not there");
		Update_Panel.showControl(0);
		Console.print(response);
	}

	else if (response.HVERSION > VERSION)
	{
		Update_Panel.showControl(1);
	}
	
	else
	{
		Update_Panel.showControl(0);
	}

	});

}

VersionCheck();

@DanH What response do you return from your server?

[DanH]

@d-healey I just get data out of a file...

[Matt_SF]

@DanH what if you use the status instead?

If the file doesn't exist you'll get a 404 code...

[DanH]

@Matt_SF well another issue is that if the user is not online then the update message also displays... That's an easier check to do though I think

[DanH]

Maybe I can just check that the file exists first though before executing any Server commands?

[DanH]

@Matt_SF ok so yes I get a 404 code in an html error message - how can I use that? I'm just thinking if my server goes down (which it did the other day) I don't want loads of people thinking there's an update available

[DanH]

ok found this in docs... will try!

if(status == Server.StatusOK)

[Matt_SF]

@DanH you can check if the user is online with Server.isOnline

Simply :

	if(status == 404) 
	{
		Console.print("it's not there");
		Update_Panel.showControl(0);
		return;
	}

Just FYI, I form myself, am using a custom api route (wordpress) which outputs an object like this :

{
    'MajorVersion'=>'1',
    'MinorVersion'=>'0',
    'Patch'=>'0',
    'isActivated'=> false  
};

The ``ìsActivated``` key allows me to control if I want the update info to be displayed in the plugin or not.

[DanH]

@Matt_SF Thanks! Using Server.isOnline currently, and

if(status == Server.StatusOK)

is working well... @Christoph-Hart what is this checking exactly?

[Christoph Hart]

Server.StatusOK is just 200 which is the official HTTP response code for "everything alright buddy, you're doing great, that's a fabulous request you've made here!"
