python - yowsup - 集成发送和接收

Question

背景:

我想将 yowsup 集成到我的家庭自动化项目中。我看过一个关于如何接收消息的简单示例，经过一些小的更改后它工作正常。

问题:

当涉及到集成发送消息功能时，我的问题就开始了。这是我正在使用的两个文件:

运行.py

from layer import EchoLayer

from yowsup.layers.auth import YowAuthenticationProtocolLayer
from yowsup.layers.protocol_messages import YowMessagesProtocolLayer
from yowsup.layers.protocol_receipts import YowReceiptProtocolLayer

        EchoLayer,
        (YowAuthenticationProtocolLayer, YowMessagesProtocolLayer, YowReceiptProtocolLayer, YowAckProtocolLayer, YowPresenceProtocolLayer)
    ) + YOWSUP_CORE_LAYERS

    stack = YowStack(layers)
    # Setting credentials
    stack.setProp(YowAuthenticationProtocolLayer.PROP_CREDENTIALS, CREDENTIALS)

    # WhatsApp server address

    stack.setProp(YowCoderLayer.PROP_DOMAIN, YowConstants.DOMAIN)

    # Sending connecting signal
    stack.broadcastEvent(YowLayerEvent(YowNetworkLayer.EVENT_STATE_CONNECT))

    # Program main loop
    stack.loop()

                messageEntity = TextMessageProtocolEntity(message, to = phone)
            elif '-' in phone:
                messageEntity = TextMessageProtocolEntity(message, to = "%s@g.us" % phone)
            else:
                messageEntity = TextMessageProtocolEntity(message, to = "%s@s.whatsapp.net" % phone)
            self.ackQueue.append(messageEntity.getId())
            self.toLower(messageEntity)
        self.lock.release()

    @ProtocolEntityCallback("ack")
    def onAck(self, entity):
        self.lock.acquire()

        if entity.getId() in self.ackQueue:
            self.ackQueue.pop(self.ackQueue.index(entity.getId()))

        if not len(self.ackQueue):
            logger.info("Message sent")
            #raise KeyboardInterrupt()

        self.lock.release()

问题:

• 我应该在哪里调用 send_message 方法，以便我可以在需要的地方发送消息？
• 是否有我可以用来发送消息的常规事件(每秒或某时触发)？

Answer 1

@ProtocolEntityCallback("send_message")
    def sendMessage(self, destination, message, messageProtocolEntity):
        outgoingMessageProtocolEntity = TextMessageProtocolEntity(
        message,
        to = destination + "@s.whatsapp.net")
        self.toLower(outgoingMessageProtocolEntity)

在要调用的上述代码 sendMessage 中，protocolEntity.getTag() == "send_message" 必须为 True。您不需要它来发送消息。

        recv_msg.append((messageProtocolEntity.getFrom(),messageProtocolEntity.getBody()))

    #send receipt otherwise we keep receiving the same message over and over

            logger.info("Message sent")

要发送消息，请在堆栈 run.py 中定义函数 send_message。您还可以导入 run.py 并使用它在其他脚本中的功能。

from layer import EchoLayer, recv_msg
CREDENTIALS = ("phone", "pwd")
def send_message(destination, message):

    ''' 
    destination is <phone number> without '+'
    and with country code of type string,
    message is string
    e.g send_message('11133434343','hello')
    '''
    messages = [(destination, message)]
    layers = (EchoLayer,
              (YowAuthenticationProtocolLayer,
               YowMessagesProtocolLayer,
               YowReceiptProtocolLayer,
               YowAckProtocolLayer,
               YowPresenceProtocolLayer)
              ) + YOWSUP_CORE_LAYERS
    stack = YowStack(layers)
    stack.setProp(EchoLayer.PROP_MESSAGES, messages)
    stack.setProp(YowAuthenticationProtocolLayer.PROP_PASSIVE, True)
    # Setting credentials
    stack.setProp(YowAuthenticationProtocolLayer.PROP_CREDENTIALS, CREDENTIALS)

    # WhatsApp server address
    stack.setProp(YowNetworkLayer.PROP_ENDPOINT, YowConstants.ENDPOINTS[0])
    stack.setProp(YowCoderLayer.PROP_DOMAIN, YowConstants.DOMAIN)              
    stack.setProp(YowCoderLayer.PROP_RESOURCE, env.CURRENT_ENV.getResource())

    # Sending connecting signal
    stack.broadcastEvent(YowLayerEvent(YowNetworkLayer.EVENT_STATE_CONNECT))
    try:
        # Program main loop
        stack.loop()
    except AuthError as e:
        print('Authentication error %s' % e.message)
        sys.exit(1)

def recv_message():
    layers = (  EchoLayer,
                (YowAuthenticationProtocolLayer, YowMessagesProtocolLayer,
                YowReceiptProtocolLayer, YowAckProtocolLayer,
                YowPresenceProtocolLayer)
             ) + YOWSUP_CORE_LAYERS

    stack = YowStack(layers)
    # Setting credentials
    stack.setProp(YowAuthenticationProtocolLayer.PROP_CREDENTIALS, CREDENTIALS)

    # WhatsApp server address
    stack.setProp(YowNetworkLayer.PROP_ENDPOINT, YowConstants.ENDPOINTS[0])
    stack.setProp(YowCoderLayer.PROP_DOMAIN, YowConstants.DOMAIN)
    stack.setProp(YowCoderLayer.PROP_RESOURCE, env.CURRENT_ENV.getResource())

    # Sending connecting signal
    stack.broadcastEvent(YowLayerEvent(YowNetworkLayer.EVENT_STATE_CONNECT))
    try:
        # Program main loop
        stack.loop()
    except AuthError as e:
        print('Authentication error %s' % e.message)
        sys.exit(1)

if __name__ == '__main__':
    if len(sys.argv) == 1:
        print('%s send number message\nrecv\n' % sys.argv[0])
        sys.exit(1)
    if sys.argv[1] == 'send':
        try:
            send_message(sys.argv[2],sys.argv[3])
        except KeyboardInterrupt:
            print('closing')
            sys.exit(0)
    if sys.argv[1] == 'recv':
        try:
            recv_message()
        except KeyboardInterrupt:
            print('closing')
            sys.exit(0)
        for m in recv_msg:
            print('From %s:\n%s\n' % m)

现在您可以通过调用 send_message('1234567890','Howdy') 发送消息，并通过调用 recv_message() 接收消息。
