How to Build a Python WeChat Bot for Timed Girlfriend Messages

Purpose

Automates relationship care using Python and the wxpy library to send scheduled WeChat messages (morning wake‑up, lunch, dinner, bedtime, holiday and birthday greetings) and to fetch a daily English learning snippet. The bot also performs sentiment analysis on incoming messages.

Configuration File

All customizable parameters are stored in config.ini. The script reads the file with configparser and extracts values such as the girlfriend's WeChat name, scheduled times, birthday, and flags for English learning and emoji usage.

cf = configparser.ConfigParser()
cf.read("./config.ini", encoding='UTF-8')
my_lady_wechat_name = cf.get("configuration", "my_lady_wechat_name")
say_good_morning = cf.get("configuration", "say_good_morning")
say_good_lunch = cf.get("configuration", "say_good_lunch")
say_good_dinner = cf.get("configuration", "say_good_dinner")
say_good_dream = cf.get("configuration", "say_good_dream")
birthday_month = cf.get("configuration", "birthday_month")
birthday_day = cf.get("configuration", "birthday_day")
flag_learn_english = cf.get("configuration", "flag_learn_english") == '1'
flag_wx_emoj = cf.get("configuration", "flag_wx_emoj") == '1'

Message Templates

Greeting sentences are stored as plain‑text files under remind_sentence/. The script loads each list at runtime. Emoji strings are defined in a single line and split into an array.

with open("./remind_sentence/sentence_good_morning.txt", "r", encoding='UTF-8') as f:
    str_list_good_morning = f.readlines()
with open("./remind_sentence/sentence_good_lunch.txt", "r", encoding='UTF-8') as f:
    str_list_good_lunch = f.readlines()
with open("./remind_sentence/sentence_good_dinner.txt", "r", encoding='UTF-8') as f:
    str_list_good_dinner = f.readlines()
with open("./remind_sentence/sentence_good_dream.txt", "r", encoding='UTF-8') as f:
    str_list_good_dream = f.readlines()
str_emoj = "(•‾̑⌣‾̑•)✧˖°----(๑´ڡ`๑)----(๑¯ิε ¯ิ๑)----(๑•́ ₃ •̀๑)----( ∙̆ .̯ ∙̆ )"
str_list_emoj = str_emoj.split('----')

Holiday and Birthday Messages

Special messages for Valentine’s Day, Women’s Day, Christmas Eve, Christmas and birthday are read from the configuration.

str_Valentine = cf.get("configuration", "str_Valentine")
str_Women = cf.get("configuration", "str_Women")
str_Christmas_Eve = cf.get("configuration", "str_Christmas_Eve")
str_Christmas = cf.get("configuration", "str_Christmas")
str_birthday = cf.get("configuration", "str_birthday")

Bot Initialization

The script creates a Bot instance differently for Windows/macOS and Linux to handle QR‑code login.

if 'Windows' in platform.system():
    bot = Bot()
elif 'Darwin' in platform.system():
    bot = Bot()
elif 'Linux' in platform.system():
    bot = Bot(console_qr=2, cache_path=True)
else:
    print("Unable to detect OS, please set manually")

English Learning

Daily English sentences are fetched from the free API http://open.iciba.com/dsapi/.

def get_message():
    r = requests.get("http://open.iciba.com/dsapi/")
    note = r.json()['note']
    content = r.json()['content']
    return note, content

Sentiment Analysis

Incoming messages are sent to BosonNLP’s sentiment API; the returned score (0‑1) indicates mood.

postData = {'data': msg.text}
response = post('https://bosonnlp.com/analysis/sentiment?analysisType=', data=postData)
data = response.text
now_mod_rank = (data.split(',')[0]).replace('[[','')
print(f"Message: {msg.text}
Sentiment score: {now_mod_rank}")

Message Sending Function

def send_message(your_message):
    try:
        my_friend = bot.friends().search(my_lady_wechat_name)[0]
        my_friend.send(your_message)
    except:
        bot.file_helper.send(u"守护女友出问题了，赶紧去看看咋回事~")

Scheduling Loop

An infinite loop checks the current time string and triggers the appropriate greeting. Emoji addition and English learning flags are respected.

while True:
    now_time = time.ctime()[-13:-8]
    if now_time == say_good_morning:
        message = choice(str_list_good_morning)
        if flag_wx_emoj:
            message += choice(str_list_emoj)
        send_message(message)
    # similar blocks for lunch, dinner, sleep, birthday, holidays, etc.
    time.sleep(60)

Running the Bot

t = Thread(target=start_care, name='start_care')
t.start()

Installation
