Python Plugin: Growatt Inverter

[sincze]

Currently working on a plugin for Growatt Web.
Solved, Initial Release: https://github.com/sincze/Domoticz-Grow ... ver-Plugin

Looking at the API calls from the APP they have and it is unfortunately HTTP.

I have to post the password in md5 and the username to a url.

Code: Select all

            sendData = { 'Verb' : 'POST',
                         'URL'  : '/newTwoLoginAPI.do',
                         'Headers' : self.apiRequestHeaders(),
                         'Data': "password="+password.hexdigest()+"&userName="+Parameters["Username"]
                         }
            Domoticz.Debug("SendData: "+str(sendData))
            Connection.Send(sendData)

It all seems to work fine however... the framework automatically creates a Authorization Basic now and the webserver does not like that offering me a 400 (Bad Request).

Code: Select all

2019-08-11 00:36:53.666 (Growatt via Google) ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** POST./newTwoLoginAPI

2019-08-11 00:36:53.667 (Growatt via Google) ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ****************==..

Can I disable the Authorization Basic somehow?

@sincze,

It only injects that header if both the actual Username & Password Parameters have values. To prevent that you can use a different Parameter to collect the Username (e.g Mode1 with a label of "Username")

Thanks for your always quick replys to keep people motivated and going.
I would also think you are right indeed. The test setup: Domoticz was running on: V4.11062 now updated to: Domoticz V4.11079

Plugin Parameters setup like:

Code: Select all

<param field="Address" label="Server Address" width="200px" required="true" default="server-api.growatt.com"/>        
<param field="Mode2" label="Portal Username" width="200px" required="true" default="admin"/>
<param field="Password" label="Portal Password" width="200px" required="true" password="true"/>
<param field="Mode1" label="Protocol" width="75px">

That is as described in your answer, right?

Plugin thing that needs to happen:

Code: Select all

        if (Status == 0):
            Domoticz.Debug("Google connected successfully.")            
            password=Parameters["Password"]
            password=hashlib.md5(str.encode(password))
            Domoticz.Debug("Password_1 is now: "+password.hexdigest())
            sendData = { 'Verb' : 'POST',
                         'URL'  : '/newTwoLoginAPI.do',
                         'Headers' : self.apiRequestHeaders(),
                         'Data': "password="+password.hexdigest()+"&userName="+Parameters["Mode2"]
                         }
            Domoticz.Debug("SendData: "+str(sendData))
            Connection.Send(sendData)
        else:
            Domoticz.Log("Failed to connect ("+str(Status)+") to: "+Parameters["Address"]+":"+Parameters["Mode1"]+" with error: "+Description)

But the logging shows BasicAuth

Changing both username and Password fields to 'ModeX' give me a result with HTTP protocol.
Maybe something not 100% in the code if both username and password fields are filled?

Code: Select all

        <param field="Address" label="Server Address" width="200px" required="true" default="server-api.growatt.com"/>        
        <param field="Mode2" label="Portal Username" width="200px" required="true" default="admin"/>
        <param field="Mode3" label="Portal Password" width="200px" required="true" password="true"/>
        <param field="Mode1" label="Protocol" width="75px">

[Dnpwwo]

@sincze,

You only had to change one to get the result. If you didn't delete and create the hardware again the old Parameter may have still been handed to the plugin?

Glad its sorted either way.

-> "If you didn't delete and create the hardware again the old Parameter may have still been handed to the plugin?"

That must be it did not DELETE the hardware I'll revert changes later back to your suggestions.
Currently trying to extract from HEADERS:

The session ID so I can submit that in the following request as a Cookie.
Any functions for that on your shelf ?

The following is shown in the Domoticz log, for authentication I need:

@sincze,

The framework currently treats http headers as a simple dictionary of strings which may need to change. Duplicates should probably be handled via a list.

I'm travelling at the moment but can have a look later in the week.

I'm travelling at the moment but can have a look later in the week.

That would be appreciated as I can only use existing functionalities.
I am not a (python) developer at all I study other peoples products, to learn, figure out how their plugin works and create my 'own'.

[Dnpwwo]

@sincze,

I pushed an upgrade tonight that allows headers to be strings, bytes, bytearrays or lists. When a list is supplied all the list values are injected as separate headers of the specifed type.

e.g:

Code: Select all

            sendData = { 'Verb' : 'GET',
                         'URL'  : '/',
                         'Headers' : { 'Content-Type': 'text/xml; charset=utf-8', \
                                       'Connection': 'keep-alive', \
                                       'Accept': 'Content-Type: text/html; charset=UTF-8', \
                                       'Host': Parameters["Address"]+":"+Parameters["Mode1"], \
                                       'User-Agent':'Domoticz/1.0',
				       'Cookie': ['CONSENT=WP.278be6',
						  b'ANID=AHWqTUkA63jkRUDy98OeQlgB2tzyyYqKWCHPADiSGOGc5ZVtduyCgaMVgzonI3Rn'] }
                       }
            Connection.Send(sendData)

will create 2 'Cookie' headers in the request.

Response Headers will also have List objects when multiple headers are returned

@Dnpwwo, Wow nice. Let me upgrade tonight or tomorrow to latest beta version and give it a try.
Just finished a Shelly1 project.
Now on to Sonoff at my parents place.

Currently on: Domoticz V4.11214

This is the request I need to make

growat0-request.png (9.46 KiB) Viewed 7739 times

I extracted the sessionId and serverId into 2 separate variables.

Code: Select all

    def ProcessCookie(self, httpDict):
        if isinstance(httpDict, dict):

                if isinstance(httpDict[x], dict):
                    if (x == "Headers"):
                        Domoticz.Debug("---> Headers found")    
                        for y in httpDict[x]:
                            if (y == "Set-Cookie"):        
                                Domoticz.Debug("---> Process Cookie Started")
                                self.cookieAvailable = True                                                                
                                self.sessionId = re.search(r"(?<=JSESSIONID=).*?(?=;)", str(httpDict[x][y])).group(0)
                                self.serverId =  re.search(r"(?<=SERVERID=).*?(?=;)", str(httpDict[x][y])).group(0)
                                Domoticz.Debug("---> Process Cookie Cookies found "+ str(httpDict[x][y]) )

Now finding out how to use it in the cookie ;-0

Code: Select all

        return {
            'Verb': 'POST',
            'URL': '/newTwoPlantAPI.do?op=getUserCenterEnertyDataByPlantid',
            'Cookie': "[JSESSIONID="+self.sessionid+" ,SERVERID="+self.serverid+"]",
            'Data': "plantId="+str(self.plantId)+"&language=1",
            'Headers': self.apiRequestHeaders()
        }
        
    def apiRequestHeaders(self):

            'Accept-Encoding': 'gzip'
        }
             

At the moment still out of luck.

mmmm... what did I miss.

[Dnpwwo]

@sincze ,

You aren't creating a proper Python list structure. If you check my sample the [ and ] are not enclosed in quotes.

Code: Select all

'Cookie': "[JSESSIONID="+self.sessionid+" ,SERVERID="+self.serverid+"]",

should be

Code: Select all

'Cookie': ["JSESSIONID="+self.sessionid, "SERVERID="+self.serverid],

[sincze]

So I created this function:

Code: Select all

    def apiRequestHeaders_withcookie(self):
        return {
            'Verb': 'POST',
            'URL': '/newTwoPlantAPI.do?op=getUserCenterEnertyDataByPlantid',
            'Headers' : { 'Content-Type': 'application/x-www-form-urlencoded; charset=utf-8',
                          'Connection': 'keep-alive',
                          'Host': 'server-api.growatt.com',
                          'User-Agent': 'Domoticz/1.0',
                          'Accept-Encoding': 'gzip',
                          'Cookie': ["JSESSIONID="+self.sessionid, "SERVERID="+self.serverid],
                          'Data': "plantId"+str(self.plantId)+"&language=1"
                       }
        }

It should represent all data in correct format (checked with separate python program in cli).

Code: Select all

I received: {'URL': '/newTwoPlantAPI.do?op=getUserCenterEnertyDataByPlantid', 'Headers': {'Accept-Encoding': 'gzip', 'Data': 'plantId=12345&language=1', 'Host': 'server-api.growatt.com', 'User-Agent': 'Domoticz/1.0', 'Connection': 'keep-alive', 'Cookie': ['JSESSIONID=********9********DEA18A1A049C69A', 'SERVERID=0e6c72164********30********1651c|********|********], 'Content-Type': 'application/x-www-form-urlencoded; charset=utf-8'}, 'Verb': 'POST'}

However while executing debugging in the plugin using:

Code: Select all

Domoticz.Debug("Cookie 1 apiURL StationDataRequest: "+str(self.apiRequestHeaders_withcookie() ) )

It stops exactly there.. No entry in the Domoticz log.
If I remove the line the plugin continues... ofcourse the

Code: Select all

Connection.Send(self.apiRequestHeaders_withcookie() )

also does not work.. I missed something in the function.. Don't know yet what...

[Dnpwwo]

@sincze,

Not sure why the debug statement doesn't work but your 'Data' line is wrong.

• it isn't a header so should be outside the header dictionary (i.e after the "}")
• "plantId"+str should be "plantId="+str

if you want to debug the structure I made a better logging function recently:

Code: Select all

def DumpHTTPResponseToLog(httpResp, level=0):
    if (level==0): Domoticz.Debug("HTTP Details ("+str(len(httpResp))+"):")
    indentStr = ""
    for x in range(level):
        indentStr += "----"
    if isinstance(httpResp, dict):
        for x in httpResp:
            if not isinstance(httpResp[x], dict) and not isinstance(httpResp[x], list):
                Domoticz.Debug(indentStr + ">'" + x + "':'" + str(httpResp[x]) + "'")
            else:
                Domoticz.Debug(indentStr + ">'" + x + "':")
                DumpHTTPResponseToLog(httpResp[x], level+1)
    elif isinstance(httpResp, list):
        for x in httpResp:
            Domoticz.Debug(indentStr + "['" + x + "']")
    else:
        Domoticz.Debug(indentStr + ">'" + x + "':'" + str(httpResp[x]) + "'")

don't be put off by the name, it will handle a Request as well, try that.

[sincze]

"Not sure why the debug statement doesn't work but your 'Data' line is wrong."

This gives me an output with the dumphttp function, however due to missing cookie a 302 no login.:

Code: Select all

    def apiRequestHeaders_withcookie(self):
        return {
            'Verb': 'POST',
            'URL': '/newTwoPlantAPI.do?op=getUserCenterEnertyDataByPlantid',
            'Headers' : { 'Content-Type': 'application/x-www-form-urlencoded; charset=utf-8',
#                          'Cookie': ["JSESSIONID="+self.sessionid, "SERVERID="+self.serverid],
                          'Connection': 'keep-alive',
                          'Host': 'server-api.growatt.com',
                          'User-Agent': 'Domoticz/1.0',
                          'Accept-Encoding': 'gzip',
                        },
            'Data': "plantId="+str(self.plantId)+"&language=1",
        }

This does not (no output just as described earlier).

Code: Select all

    def apiRequestHeaders_withcookie(self):
        return {
            'Verb': 'POST',
            'URL': '/newTwoPlantAPI.do?op=getUserCenterEnertyDataByPlantid',
            'Headers' : { 'Content-Type': 'application/x-www-form-urlencoded; charset=utf-8',
                          'Cookie': ["JSESSIONID="+self.sessionid, "SERVERID="+self.serverid],
                          'Connection': 'keep-alive',
                          'Host': 'server-api.growatt.com',
                          'User-Agent': 'Domoticz/1.0',
                          'Accept-Encoding': 'gzip',
                        },
            'Data': "plantId="+str(self.plantId)+"&language=1",
        }

The offending article is the Cookie line.. but why

[Dnpwwo]

When troubleshooting I always keep it simple, its always the assumptions that kill you.

Try replacing your 'cookie' line with mine which is hard coded. It will fail the logon but should at least dump the output and do the send.

Also turn debugging up to the max.

[sincze]

Debug is set to all.

using @Dnpwwo excluding technique figured out the trick.

Code: Select all

'Cookie': ['JSESSIONID='+self.sessionid, 'SERVERID='+self.serverid]

Success.

[sincze]

So "DumpHTTPResponseToLog(self.apiRequestHeaders_withcookie())"
Gives me the following, however no usefull data JSON from the server.
But at least we are moving forward.

Code: Select all
