SendToHTTP problem with URL lenght?

[jopare]

Hi, currently I'm struggling with SendToHTTP with a longer URL. In general my config works when i use for example the following rule:

Code: Select all

on System#Boot do
gpio,2,0 
endon 
on Push#state do
if [Push#state]=1
SendToHTTP 192.168.0.50,8085,/room?cmd=set%20VC20_Steckdose_03%20on
else
gpio,2,0
endif
endon

No trouble with that, the above URL works from any Browser and also from this rule. When i try the same rule with the following URL, it doesn't work:
192.168.0.16,80,/control/trigger_event? ... rom_piface
But, this URL works also from any Browser. One, maybe interessting thing is, that the URL is trunkated in the log. The last 7 characters are missing.
I've also modified the required IPaddress, port, userid and password in the Generic HTTP device configuration. Any help will be appreciated, thanks in advance.

Yes you're probably hitting the max length for a rule/command line.

Possible to shorten the URL?

Unfortunately I can't shorten the URL. What's the max. length? I've read about a limitation problem in former releases but as far as i understood this was eliminated.
Thanks so far.

It may very well be the limit for these is 80 bytes.
The parameter (separated by a ',') has a length of 100 bytes in your example and I guess the limit for those is 80.
That still doesn't explain why you're missing 7 bytes.
The entire line is 128 bytes

Code: Select all

SendToHTTP 192.168.0.16,80,/control/trigger_event?event_name=OnButPressed_roomsystem.0&event_source=alsapi.keyboard.from_piface

And that one may be limited to 120 bytes, which makes loosing 7 bytes a lot more likely.

Thing is we have had a lot of strange crashes, which appeared to be stack overflows while parsing the rules.
So it has been 240 bytes a while ago, but that's been lowered to keep the stack from overflowing.
A lot of this parsing has been looked into already to lower memory usage, but I guess if there's still some limit like this one, it hasn't been altered yet.

SendToHTTP,192.168.0.16,80,/control/trigger_event?event_name=OnButPressed_roomsystem.0&event_source=alsapi.keyboard.from_piface

Just a thought, if you have any control over the receiving end you should get those event names shorten (bold in the text above).

Thanks for your suggestions, I got it fixed with a very short Hostname instead of the IP-address.

Good you got it fixed
