Chatbots are in fashion nowadays. Almost every business in an attempt to reduce costs or to allocate more work to human customer support tries to create a chatbot. Well, on my projects I don’t really a need a chatbot or any type of AI to provide support, so I tried to make a simple bot to use on my daily life. You know the type: to write ‘Hello, good morning’ to a group everyday, to reply back ‘thanks’ when it’s your birthday… Perfect for someone lazy!<\/p>\n\n\n\n

Chatbots aren’t really that hard to create. There are loads of guides online, and amazing code is available on github for example. One of my favorites was a bot for whatsapp<\/a>, an app I use daily. Oh and by the way, Facebook doesn’t like when you run bots on WhatsApp for a long time. They will ban you. So… avoid that.<\/p>\n\n\n\n

Built with NodeJs it uses WAPI.js to provide a python interface for interacting with WhatsAPP Web to send and receive Whatsapp messages.<\/p>\n\n\n\n

In bot.json you can edit the strings and the node application behavior:<\/p>\n\n\n\n

{\n    \"appconfig\": {\n        \"headless\": false,\n        \"isGroupReply\":false,\n        \"webhook\":\"\"\n    },\n    \"bot\": [{\n            \"contains\": [],\n            \"exact\": [\"hi\"],\n            \"response\": \"{hello|howdy}\"\n        },\n        {\n            \"contains\": [],\n            \"exact\": [\"hello\"],\n            \"response\": \"hi\",\n            \"file\":\"noFile.png\"\n        },\n        {\n            \"contains\": [],\n            \"exact\": [\"hy\"],\n            \"response\": \"hi\",\n            \"file\":\"github.png\"\n        },\n        {\n            \"contains\": [],\n            \"exact\": [\"hiee\"],\n            \"response\": \"hi\"\n        },\n        {\n            \"contains\": [],\n            \"exact\": [\"github\"],\n            \"response\": \"Git Hub Logo\",\n            \"file\":\"github.png\"\n        }\n    ],\n    \"blocked\": [],\n    \"noMatch\":\"{\ud83e\udd14|\ud83d\udc4d}\",\n    \"smartreply\":{\n        \"suggestions\":[],\n        \"clicktosend\":true\n    }\n}<\/code><\/pre>\n\n\n\n
As you can see by some strings, there’s not really any AI here. All the replies must be hand written, all the images must be self hosted. It’s simple, but fun.<\/p>\n\n\n\n
There’s also some bots based on selenium that reply only on valid commands.<\/p>\n\n\n\n
class BotConfig(object):\n    last_msg = False\n    last_msg_id = False\n\n    command_history = []\n    last_command = \"\"\n\n    def __init__(self, contact_list):\n        self.contacts = contact_list\n\n    def get_contacts(self):\n        return self.contacts\n\n    def set_last_chat_message(self, msg, time_id):\n        self.last_msg = msg\n        self.last_msg_id = time_id\n\n    def get_last_chat_message(self):\n        return self.last_msg, self.last_msg_id\n\n    def set_last_command(self, command):\n        self.last_command = command\n        self.command_history.append(command)\n\n    def get_command_history(self):\n        return \"You have asked the following commands: \" + \", \".join(self.command_history)<\/code><\/pre>\n\n\n\n
Also… keeping up with python, here’s another fun one.<\/a> Like-My-GF: You setup the “target” name, setup a cron job and that’s it. Every time your SO posts something on instagram, your like is there!<\/p>\n\n\n\n
CONFIG = dict( client_id     = config_parser.get('Client', 'client_id'),\n               client_secret = config_parser.get('Client', 'client_secret'),\n               redirect_uri  = config_parser.get('Client', 'redirect_uri'),\n                 )\nOTHER = dict( scope        = ['likes'],\n              access_token = config_parser.get('Access Token', 'access_token'),\n              target       = config_parser.get('Target', 'username'),\n              log_path     = config_parser.get('Path', 'log_path')+'like_my_gf.log',\n    )<\/code><\/pre>\n","protected":false},"excerpt":{"rendered":"
