Serviio

In attemting to extract the parameters for an rtmp link in a web resource groovy I found the link http://castamp.com/embed.php?c=puurnld4 (and other c values) could not be opened as a url. ie: String linkHtml = new URL(srcUrl).getText() Explorer also returns a blank page.

I can however download the link using my downloader utility and it contains the necessary rtmp parameter values, so my question is what is the best way to download that link using groovy?

the web page is empty but has a source HTML (right click in the browser). It's possible they're expectiv some (browser like) headers, eg User-Agent

Actually the webpage does load in the browser but is quickly replaced with a blank page as per the html below. So the question remains how do I access that html in groovy when String linkHtml = new URL(srcUrl).getText()
gives me the null page ?

not sure how they are doing this, but it doesn't seem to be possible. curl and wget fail as well

Using Wireshark here are the requests made by my downloader utility (which downloads the file) and Curl which fails.

Does this give any info that will help solve this problem?

Can anyone write a curl command to duplicate the downloader request?
I've tried but have not succeeded.

More research finds that

will download a gzip'd version of the file, and I can get the gzip string in groovy with

Can someone tell me how I get groovy to uncompress the gzip format string back to text??

I'm using this in Java (you can use it in Groovy too):



You have to pass 'is' which would be the gzipped InputStream, so you have to figure out how to return InputStream from URL rather than text. Looks like then you can call .text on the gzip stream to read its contents like:

Thanks..works great

Seems I spoke too soon.

The GZIP code

works fine in my groovy in test mode and generates the correct ContentURLContainer

however when executed within Serviio the log shows this error:



Why would Serviio process this groovy differently?

My standalone version of groovy which executes my plug-in correctly is version 1.8.3. What version does Serviio have builtin which fails with my plug-in per my previous post? The failing method in Serviio was implemented in Groovy 1.8.1 so perhaps Serviio is not yet at that level.

Further testing shows that using the Serviio groovy-all.jar for my standalone testing generates the same error, which would appear to prove the Serviio groovy does not have the 1.8.1 release enhancements. The fix would be to include the groovy-1.8.3.jar in the 1.0 release.
