Have a Problem using Yowsup with simple application!

[Elklund]

I have a big problem to run this Code. I copied it from the original Code/Page and it puts out some error Messages!! That's not good, please help me...

layer.py

from yowsup.layers.interface                           import YowInterfaceLayer, ProtocolEntityCallback
from yowsup.layers.protocol_messages.protocolentities  import TextMessageProtocolEntity
from yowsup.layers.protocol_receipts.protocolentities  import OutgoingReceiptProtocolEntity
from yowsup.layers.protocol_acks.protocolentities      import OutgoingAckProtocolEntity

class EchoLayer(YowInterfaceLayer):

    @ProtocolEntityCallback("message")
    def onMessage(self, messageProtocolEntity):
        #send receipt otherwise we keep receiving the same message over and over

        if True:
            receipt = OutgoingReceiptProtocolEntity(messageProtocolEntity.getId(), messageProtocolEntity.getFrom(), 'read', messageProtocolEntity.getParticipant())

            outgoingMessageProtocolEntity = TextMessageProtocolEntity(
                messageProtocolEntity.getBody(),
                to = messageProtocolEntity.getFrom())

            self.toLower(receipt)
            self.toLower(outgoingMessageProtocolEntity)

    @ProtocolEntityCallback("receipt")
    def onReceipt(self, entity):
        ack = OutgoingAckProtocolEntity(entity.getId(), "receipt", entity.getType(), entity.getFrom())
        self.toLower(ack)

layer.py isn't the original. I copied it from here: https://github.com/tgalal/yowsup/issues/1611 run.py

from yowsup.stacks import  YowStackBuilder
from layer import EchoLayer
from yowsup.layers.auth import AuthError
from yowsup.layers import YowLayerEvent
from yowsup.layers.network import YowNetworkLayer
from yowsup.env                                import YowsupEnv

credentials = ("phone", "password") # replace with your phone and password
#CREDENTIALS = DemosArgParser._getCredentials()

if __name__==  "__main__":
    stackBuilder = YowStackBuilder()

    stack = stackBuilder\
        .pushDefaultLayers(True)\
        .push(EchoLayer)\
        .build()

    stack.setCredentials(credentials)
    stack.broadcastEvent(YowLayerEvent(YowNetworkLayer.EVENT_STATE_CONNECT))   #sending the connect signal
    stack.loop() #this is the program mainloop

It puts out these error message:

Traceback (most recent call last):
  File "run.py", line 13, in <module>
    from yowsup.layers.axolotl                     import YowAxolotlLayer
ImportError: cannot import name YowAxolotlLayer

---

How can I fix that?

Acutually I tried to solve the problem. Deleting YowAxolotLayer from Script. But the it puts out this:

Too much error Messages :(

[jlguardi]

Use run.py from https://github.com/tgalal/yowsup/blob/master/yowsup/demos/echoclient/stack.py

[Elklund]

@jlguardi One step further...But there comes this problem:

Traceback (most recent call last):
  File "run.py", line 2, in <module>
    from .layer import EchoLayer
ValueError: Attempted relative import in non-package

Your Code:

import logging
logging.basicConfig(level=logging.DEBUG)

from yowsup.stacks import  YowStackBuilder
from .layer import EchoLayer
from yowsup.layers.auth import AuthError
from yowsup.layers import YowLayerEvent
from yowsup.layers.network import YowNetworkLayer

class YowsupEchoStack(object):
    def __init__(self, credentials, encryptionEnabled = True):
        stackBuilder = YowStackBuilder()

        self.stack = stackBuilder\
            .pushDefaultLayers(encryptionEnabled)\
            .push(EchoLayer)\
            .build()

        self.stack.setCredentials(credentials)

    def start(self):
        self.stack.broadcastEvent(YowLayerEvent(YowNetworkLayer.EVENT_STATE_CONNECT))
        try:
            self.stack.loop()
        except AuthError as e:
            print("Authentication Error: %s" % e.message)

How can I fix that? Is there a problem with my layer.py?

Also I updated the Code for home automation:

layer.py

It doesn't works yet. But why? Do you have a solution? Do I have to authentificate my number via run.py?

[sowerkoku]

There is a similar project here.

[Elklund]

Thanks. But there is an IdentationError:

run.py

    stackBuilder = YowStackBuilder()

    stack = stackBuilder\
        .pushDefaultLayers(True)\
        .push(EchoLayer)\
        .build()

    stack.setProp(YowAuthenticationProtocolLayer.PROP_CREDENTIALS, CREDENTIALS) #setting credentials
    stack.broadcastEvent(YowLayerEvent(YowNetworkLayer.EVENT_STATE_CONNECT)) #sending the connect signal
    stack.setProp(YowNetworkLayer.PROP_ENDPOINT, YowConstants.ENDPOINTS[0]) #whatsapp server address
    stack.setProp(YowCoderLayer.PROP_DOMAIN, YowConstants.DOMAIN)
    stack.setProp(YowCoderLayer.PROP_RESOURCE, YowsupEnv.getCurrent().getResource()) #info about us as WhatsApp client
    stack.loop( timeout = 0.5, discrete = 0.5 )     

When I run that it puts out this message:

  File "run.py", line 11
    stackBuilder = YowStackBuilder()
    ^
IndentationError: unexpected indent

Is it because I have only copied the content of the files? And not copied the files?

[Elklund]

OK. I fixed the IdentationError. Thank you very much :)
