Yowsup: Is there any working example?

[someone235]

When I run your sample application I get:

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

Is there any working example that I can use?

When I run your sample application I get:

Traceback (most recent call last):
File "run.py", line 13, in
from yowsup.layers.axolotl import YowAxolotlLayer
ImportError: cannot import name YowAxolotlLayer
Is there any working example that I can use?

Probably the sample application is out-dated :
Consider commit "Split up axolotl into 3 layers"

Compare with issue #1611

Hope that it helps.

When I copy the code from #1611 I get this error: yowsup.layers.auth.autherror.AuthError: not-authorized
(BTW, everything works fine when I'm using the cli demos)

[dargmuesli]

Don't use run.py II. @albert-chin is completely right. There is no YowAxolotlLayer anymore. Just use:

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

[someone235]

Tried it too, still getting yowsup.layers.auth.autherror.AuthError: not-authorized

[dargmuesli]

Which OS are you using? Did you change your install in some way? Which stack and layer code do you use? How did you configure your config? Can you reregister?

[someone235]

I'm using Ubuntu 15.10, and I didn't change neither the config or the install. Here's my full code:

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)

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") # in my code it's my real phone and password

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

[dargmuesli]

(Why do you import YowsupEnv?)
I don't think it's a problem with your layer.py.
So, try this as stack.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

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)

Then save this as run.py:

import client

credentials = ("phone", "password")
stack = client.YowsupEchoStack(credentials)
stack.start()

And this as __init__.py:

from .stack import YowsupEchoStack

And put the files in the following folder structure:

      \---client
                +---__init__.py
                +---layer.py
                +---stack.py
      +---run.py

I hope I didn't forget anything as I did not test this special case, but at least that's a clean way I do. You can also try to copy the logging function out of the demos, but I do not really believe that you get more information about this error there.

I'm still getting Authentication Error: not-authorized

[peletiah]

I had the same issue, but after re-registering my account via the yowsup-client it works (I had verified the same account from my phone's client in between, that seem's to have invalidated the yowsup-credentials).

One other thing I confused is that you can't use the same account on the phone and the yowsup-client.

I registered with one account via the yowsup-cli (See https://github.com/tgalal/yowsup/issues/1742) and a second via the whatsapp-android-client. When I now send messages to the yowsup-account from the android-client, I get my own message as a reply from the yowsup-echo-client.

[someone235]

I don't have the same problem. I had the above problem just after I registered via the yowsup-cli

[peletiah]

One other issue I came upon yesterday was getting Authentication Error: not-authorized after it had worked for a while. When I checked with the yowsup-cli (with "--requestcode"), I received the reply that I was blocked by the WhatsApp-server. Apparently I have made too many bad requests while debugging or sent to many messages to the same client.

Unless you have already verified, this might also be a cause...?

[someone235]

I verified with SMS, and all worked good

[peletiah]

Too bad :-/

I've set it up exactly as @Dargmuesli fleshed out, with the Layer IV from the sample-app and it worked fine (Until I ran into the ban-issue).

[kaden890172]

Thank you @Dargmuesli the solution you provided works flawlessly!
