Is VBoxManage guestcontrol passing parameters incorrectly?
- by Dan Jones
I had an idea of using my Windows VM (on a Ubuntu host) to open itms:// links (for iTunes) from the host. So, I'm using vboxmanage guestcontrol to make this happen.
I have a script (win_vm_launcher.sh) that takes a link as the argument, and passes it to the host like this:
vboxmanage guestcontrol "$VM" exec --image 'C:\Windows\System32\cmd.exe' --username "$USER" --password "$PASSWORD" -- /c start "$@"
This works if I copy a link from my browser, and change http to itms. E.g., for https://itunes.apple.com/us/album/new-york-city/id3202598, I can do win_vm_launcher.sh itmss://itunes.apple.com/us/album/new-york-city/id3202598 and it works fine. The album opens up in iTunes on my VM.
However, when I click a "View in iTunes" link from the iTunes site, it adds an extra parameter to the URI (specifically, the referrer), so it looks something like itmss://itunes.apple.com/us/album/new-york-city/id3202598?ign-msr=https%3A%2F%2Fitunes.apple.com%2Fus%2Falbum%2Fit-came-upon-midnight-clear%2Fid578946739
Unfortunately, if I try to run win_vm_launcher.sh itmss://itunes.apple.com/us/album/new-york-city/id3202598?ign-msr=https%3A%2F%2Fitunes.apple.com%2Fus%2Falbum%2Fit-came-upon-midnight-clear%2Fid578946739 it insteads opens up a regular Command Prompt window with the title "itmss://itunes.apple.com/us/album/new-york-city/id3202598?ign-msr=https%3A%2F%2Fitunes.apple.com%2Fus%2Falbum%2Fit-came-upon-midnight-clear%2Fid578946739". I don't even know how to set the command prompt window title, so I'm not sure how that's happening.
If I run the command in the guest, it works fine, opening the album in iTunes:
cmd /c start itmss://itunes.apple.com/us/album/new-york-city/id3202598?ign-msr=https%3A%2F%2Fitunes.apple.com%2Fus%2Falbum%2Fit-came-upon-midnight-clear%2Fid578946739
I found a VirtualBox bug that seems somewhat related, but not exactly.
It probably doesn't matter, but my host is Ubuntu 12.04, and my guest is Windows 7.
So, any idea if vboxmanage is incorrectly passing the arguments, and if so, is there a way around it?
If I can't figure out the right way to do it, I'll end up having to process each argument, and stripping out any parameters on any URIs.
P.S.
I tried creating a batch script (out.bat) like this:
echo %1 > %TEMP%/testing.txt
and then running it from the host like this: vboxmanage guestcontrol "$VM" exec --image 'C:\Windows\System32\cmd.exe' --username "$USER" --password "$PASSWORD" -- /c "C:\path\to\out.bat" "itmss://itunes.apple.com/us/album/new-york-city/id3202598?ign-msr=https%3A%2F%2Fitunes.apple.com%2Fus%2Falbum%2Fit-came-upon-midnight-clear%2Fid578946739"
It ran as expected, and when I open %TEMP%/testing.txt, it contained:
"itmss://itunes.apple.com/us/album/new-york-city/id3202598?ign-msr=https%3A%2F%2Fitunes.apple.com%2Fus%2Falbum%2Fit-came-upon-midnight-clear%2Fid578946739"
including the quotes. So, it sort of passed the parameter correctly (not sure why it still had quotes), so maybe the problem is with cmd.exe, or even the start command. I'm stymied.
