Problem with SendToHTTP

#1 Post by HermannDerUser » 20 Feb 2019, 10:28

Hello together,
I'm new with the ESPeasy and have a problem with the SendToHTTP command. At the moment I use 'ESP_Easy_mega-20190212_normal_ESP8266_1024' on a Sonoff basic. In the rules tab I create a rule like this:

Code: Select all

on Intern#Taster do
 if [Intern#Taster]=3                             // bei Doppelklick
    SendToHTTP 192.168.69.202,80,/?relais=2
    Pulse,13,0,100                                // 3x kurz blinken
    Pulse,13,1,100
    Pulse,13,0,100
    Pulse,13,1,100
    Pulse,13,0,100
    Pulse,13,1,100                             
    endif
endon
and its work well. But if I change the SentToHTTP command to

Code: Select all

SendToHTTP 192.168.69.15,80,/api/device/fsb/buttonPressed?buttonId=fs
nothing happens. The command push a button over the API from pimatic. If I enter the command

Code: Select all

http://192.168.69.15:80/api/device/fsb/buttonPressed?buttonId=fs
in the address line of my browser, it works well.

SendToHTTP,url.com,80,/xyz is the syntax

you have space instead of coma after SendToHTTP

Now I try with comma, but that doesn't work either. On the other hand, the command

Code: Select all

SendToHTTP 192.168.69.202,80,/?relais=2
works with the space perfect. :?:

Regarding spaces, we allowed them before but not officially anymore.

BUT most likely only the first space will work in future builds.

Okay, I switched from space to comma, but...
...it's still not working.

Does anyone have any idea why this command doesn't work?

Use something like "wireshark" or "fiddle" to see what headers is being sent by the ESP Easy unit. Your receiving end might want something that the ESP isn't sending?

What is on the receiving end?

hi,

I just tried to execute the command via the browser on another computer. I noticed that a user/password query is prompted. Is it possible to specify a user/password for the SentToHTTP command.

I adjusted my rule. In the log file I now find the following entries:

Code: Select all

1695435: SendToHTTP user:Password@192.168.69.15,80,/api/device/fsb/buttonPressed?buttonId=fs
1695436: SendToHTTP: Host: user:password@192.168.69.15 port: 80
1695436: SendToHTTP: Path: /api/device/fsb/buttonPressed?buttonId=fs
My password is case-sensitive but in the HTTP request everything is lower case.
How can I change that?

That is probably not possible right now (all commands are set to lower case). You need to open a feature request for that... Sorry.

As suggested by TD-er (on slack):

"user:pAsSwRd@host:port"

So, that is double quotes on each side...

Thank you very much for the prompt reply, but it doesn't work. I tried

Code: Select all

SendToHTTP "user:Password@192.168.69.15",80,/api/device/fsb/buttonPressed?buttonId=fs

Code: Select all

SendToHTTP "user:Password@192.168.69.15,80",/api/device/fsb/buttonPressed?buttonId=fs

Code: Select all

SendToHTTP 'user:Password@192.168.69.15',80,/api/device/fsb/buttonPressed?buttonId=fs

Code: Select all

SendToHTTP 'user:Password@192.168.69.15,80',/api/device/fsb/buttonPressed?buttonId=fs
but the log said for the first example:

Code: Select all

3391935: SendToHTTP 'user:Password@192.168.69.15',80,/api/device/fsb/buttonPressed?buttonId=fs
3391936: SendToHTTP: Host: user:password@192.168.69.15 port: 80

I guess it is a bug then.
The parsing of the rules is a bit too complicated every now and then.
Comparing commands is done case-insensitive, but the parameters should be sent case sensitive.
Or else strings sent to a display for example can not have a mix of lower and upper case letters.

I am having the same problem as the OP, trying to use the SendToHTTP command to login and send a string. Did this issue ever get resolved, or are there other syntax examples I could follow? Appreciate the help.

I guess it depends on the host, if nothing is passed in the header and the host expects the authorization to be in there (not only in the URL) I guess the host will deny access.

This is the syntax of the HTTP command directly from the user manual: http://admin:12345678@192.168.0.50/Set. ... ower+P60=1

The command above works fine when entered into a browser, so I am seeking to translate the command into the ESPEasy rules to send the HTTP command under particular conditions.

Like the OP I've tried numerous combinations of the commands entered by the OP without success. Interestingly I tried using a Generic HTTP controller, which achieved partial success, but presented other types of issues. But using the HTTP controller partially proved the HTTP command was being sent and received.

Any advice greatly appreciated. Thanks, Mark

The OP's SendToHTTP statement did not work because the rules parser coverts the statement to lower case letters. That caused the OP's mixed-case password credentials to fail.

I see that your example HTTP URL has some uppercase in it:

Code: Select all

http://admin:12345678@192.168.0.50/Set.cmd?CMD=SetPower+P60=1
Looking at the OP's logs, it seems only the host info (credentials with IP address) is affected by the parser. Fortunately the Path remains unchanged. So if your web credentials have uppercase then you should change them to all lower case. That should get you going.

Hi Thomas,

Thank you. After reading the posts in this thread I checked and the login name: admin is lower case, and the password I am using is lower case with a few numbers. Only part of the web string which has upper case is

Code: Select all

Set.cmd?CMD=SetPower+P60=1
which is part of the inbuilt commands of the power switching unit and I doubt I can change it? So I might be stuck :(

Thanks, Grego

I checked and the login name: admin is lower case, and the password I am using is lower case with a few numbers. Only part of the web string which has upper case is ...[the path]
If you review the logs from the OP, his path string remained unchanged. So that optimistically suggests you might be able to make it work. To determine if this is happening I suggest you review your ESPEasy log output to see what is being sent via SendToHTTP. This will allow you to confirm if the path string is not being altered.

Regardless of what you find, this unwanted case conversion bug deserves to be fixed. You or the OP need to create a issue ticket in ESPEasy's Github.
