Load_from_url

[chrisglasier]

I have a url sitting in a webdialog. It makes a call to a callback to get a component file from a url. This works testing using localhost/subdir for skp file but not using the subdir in the online url in the webdialog (Of course later I want to use any url to collect definitions).

I thought using dialog.allow_actions_from_host(url) was the obvious solution but I get Error: #<IOError: Invalid component URL>.

Please help me to see what's wrong. Thanks

Isn't it the URL that's incorrect? A typo or something?

dialog.allow_actions_from_host(url) won't be affecting load_from_url - since they are two unrelated classes.

I don't think it's a typo because I can do it with localhost and the url for the wd is the same online host (glasier.hk ) ... but it could be of course "or something".

Couldn't one class block a url so that another cannot use it - or is that muddled thinking?

[thomthom]

The URL is misformed because of escape characters?

Just guessing here. Got more info? Example etc?

[thomthom]

Made a small test:

First to a non-existsing URL:
model.definitions.load_from_url( 'http://www.thomthom.net/foo.skp' ) Error: #<IOError: (eval):155:inload_from_url': Invalid component URL>
(eval):155
(eval):155`

Then to an existing URL:
model.definitions.load_from_url( 'http://www.thomthom.net/bar.skp' ) #<Sketchup::ComponentDefinition:0xfcdf7bc>

So it looks like your URL is simply wrong. Remember that URL's some times need special characters - for instance spaces are translated to %20 etc.

If the URL fixed? Or is it generated? If it's generated - have you outputted it for inspection? Have you tried the same URL in a browser?

Thanks for doing that.

Have attached bridge.rb.

Will do some more url sleuthing.

How do you trigger the "product" callback?

[thomthom]

I somehow managed to trigger it - clicking on "Kitchen".

Output I got was this:

true "Kitchen,0,0,0" "Kitchen.skp" "http://glasier.hk/Product/Kitchen.skp" Error: #<IOError: Invalid component URL> c:/Users/thm.ARC/Desktop/bridge/bridge.rb:68:inload_from_url'
c:/Users/thm.ARC/Desktop/bridge/bridge.rb:68:in start'

When I type http://glasier.hk/Product/Kitchen.skp into my browser I get a 404. So the problem is that your URLs leads to non-existing resources.

function suStart(node){
	var fn, params;
	fn = nset[node].Label; //WC in trial
	params = [fn,0,0,0].toString();
	window.location = "skp;product@" + params;
}

It's your server configuration you need to address. Not your plugin.

Beyond my ken!

Anything like dialog.allow_actions_from_host(url)?

If not what does that do?

Any more help much appreciated!

Thanks

It's nothing related to SketchUp. As you can see - you cannot even access the files from a web browser. Don't know what you have to do because it all depend on what type of server and configuration you have.

@chrisglasier said:

webdialog.allow_actions_from_host(url) is allowing websites to send commands to SketchUp, via window.location = "skp:command@params"; type of commands.

Chris if it's a UNIX server, you would need to have the file permissions set correctly using chmod.

[chrisglasier]

Thanks T & D.

I put skp files into a zip file which I manually download and extract to a subdirectory named in bridge.rb. I can then open each component in its location.

Do you think it possible to automate the downloads and their extraction into a named folder? I have searched but have difficulty getting to grips with the results.

If I could do that then I could demonstrate the benefits of collecting skps and json data from multiple trusted/vetted sources. If required complex js/php analysis of the data to set design criteria for example could be done say in Chrome browser before the url is plopped into the web dialog to see what the various options look like.

Please bear with me!

Well the new rbz interface will do this. The "subfolder" must be wrapped inside the zip, and currently will only end up beneath the "plugins" dir. (Google has not yet given us the option to have the extraction go someplace else.)

The other option is that if a user has a full Ruby install, the standard Ruby lib Zlib can be used to extract from several different archive formats.
Then Ruby also has some other file moving modules, as well as the Dir class.

Another option is to use platform dependent shell commands (backtick delimited, or %x delimited strings.)

Thanks but I am not sure I understand how this automates the extraction to the plug in folder. It seems you have to click the install button in extensions?

I was thinking to click a js link in my url (standalone or in wd) to pick up a plain zip file from any trusted url and extract it into one or more named local folders. Dreaming perhaps!

There are new API methods with the latest v8M2 to extract files/subfolders [into Plugins] from zip/rbz files.
However, if you already have ways of extracting them, then the moving to their new locations can be done with vanilla Ruby Dir and File commands...
