Python Plugin : HTTP Listener example question

gerardwr · Post by **gerardwr** » Wednesday 20 December 2017 23:30

I am looking for a way to add a Python Plugin thats acts like a webserver, that can be called by a webclient on antoher computer.

Running Domotizc Version: 3.8755 on RPi-1-Jessie.

I did not find much information on the HTTP Listener Python Plugin example, but I THINK it:
- adds a webserver waiting for connections from webclients
- starts a webclient on every "heartbeat" and connects to the plugin-webserver

Running the plugin the Log shows that the heartbeat-client connects to the server and responds to the client. Works!

BUT if I try to connect a client on an different machine to the plugin-server I get no response from the server, and no info in the Domoticz Log.

My Domoticz is on 192.168.0.28, and is UP:

Code: Select all

pi@raspberrypiZolder:~/domoticz/plugins/HTTPListener $ curl 192.168.0.28:8080/log
<html><head><title>Not Found</title></head><body><h1>404 Not Found</h1></body></html>

The HTTP Listener Plugin listens on the default port 127.0.0.1:8008. When I try to connect, no response:

Code: Select all

pi@raspberrypiZolder:~/domoticz/plugins/HTTPListener $ curl 192.168.0.28:8008

I would expect the client to be connected to the plugin-webserver, but that does not happen.

Stupid mistake on my part, or am I missing something?

@gerardwr,

Your summary of the example's functionality is pretty accurate. I figured there was no point in a sample that just listened without any activity.

I never tested with Curl but would expect it to work. I connected from a web browser which from memory opens a connection then issues an HTTP GET. The example returns a 200 response and

Code: Select all

<!doctype html><html><head></head><body><h1>Successful GET!!!</h1><body></html>

I would suggest:

try from a web browser
turning debug on and looking at the Domoticz log I would expect to see a connection message at a minimum. I would recommend running Domoticz from the command line to do that because HTML response don't format very well in the Web UI log

Thanks for the heads up. Took me a while before I got it. Excellent "turn key" example, once you "get it" !

Tested in a browser ( on Mac with both Safari and Chrome ) but no response, the browser is, just like Curl, "waiting"

I would suggest:

Looked at the log, it is flooded with numerous debugmessages from Heartbeat, but I did not spot a connection message from the brwoser-use yet. Will try later witch Domticz in the command-line, gives me more time to check the messages

Thx so far!

Had a better look. Started domoticz on commandline and browsed from Mac on 192.168.0.81 to the Domoticz URL defined in the plugin (192.168.0.28:8008)

In the Domicz output I see that the GET from the browser is received:
- onConnect handler is called
- onMessage handler is called
=== "succesfull get" page is sent
=== and "succesfull get" page is received again, huh!?

But the "succesfull get" page is not shown in the browser.

Could it be that the page is returned to the IP of the Domticz server instead of the Ip of the requesting browser?

Detailed output is:

Maybe this could provide some help.
Attached plugin that implement Server/client communication.
plugin.py ==> execute the Server part and wait for client connection
btle.py ==> client connecting to the server and sending information.
if you connect to the Server using browser, you get Successful GET!!! message

Thanks @zak45,

Will try that later today.

@gerardwr
take care : there is a problem in Domoticz/Python and the Tcp connection
if you reload the plugin, tcp connection is not closed and reopen.. but remain opened.
you need to change the Port number every time.

Dnpwwo know that and I think he or someonelse work on it...

@zak54

Just tested yor BTLEscan plugin, and I can connect to the server part:

At least I know now that the problem is not in my setup, but in the HTTP Listener example.
@Dnpwwo can probably help there.

For the time being I will have a more detailed look at the server part of your plugin and use this as a foundation for my own server plugin.

Thanks, you saved me many hours!

I compared the code from "HTTP Listener" and "BTLE Scanner" for a clue why a client did not get a response from the HTTP Listener, while it does get a response from BTLE Scanner.

The onConnect code from HTT Listener is:

Code: Select all

    def onConnect(self, Connection, Status, Description):
        if (Status == 0):
            Domoticz.Log("Connected successfully to: "+Connection.Address+":"+Connection.Port)
        else:
            Domoticz.Log("Failed to connect ("+str(Status)+") to: "+Connection.Address+":"+Connection.Port+" with error: "+Description)
        Domoticz.Log(str(Connection))
        if (Connection != self.httpClientConn):
            self.httpServerConns[Connection.Name] = Connection

The onConnectcode from BTLE Scanner is:

Code: Select all

def onConnect(Connection, Status, Description):
    global httpServerConn , httpServerConns , httpClientConn

    if (Status == 0):
        Domoticz.Log("Connected successfully to: "+Connection.Address+":"+Connection.Port)
    else:
        Domoticz.Log("Failed to connect ("+str(Status)+") to: "+Connection.Address+":"+Connection.Port+" with error: "+Description)
        Domoticz.Log(str(Connection))
    if (Connection != httpClientConn):
            httpServerConns[Connection.Name] = Connection
            httpClientConn = Connection
    return

The only difference is the line:

Code: Select all

            httpClientConn = Connection

After adding this line to the HTPP Listener example now the clients get a response! Buy I guess the onHeartbeat will now not get a response anymore.

I think it's best that @Dnwppo evaluates what changes would be required to the HTTListener example.

Thanks to @Dnwppo and @zak54 for their assistence
