使用 python 的 webbrowser 模块的 WhatsApp 发短信

Question

import webbrowser
import time
import datetime

name = input('Enter the contact number of a person you want to send message in WhatsApp: ')
message = input('Enter the message: ')
time1 = input('Enter time in {hh:mm:ss} format: ')
print(f'Time entered by user: {time1}')
while True:
    current_time = time.ctime()
    time_format = current_time[11:19]
    time.sleep(1)
    print(f'Current time: {time_format}')
    if time1 == time_format:
        webbrowser.open_new_tab(f'https://web.whatsapp.com/send?phone=+91{name}&text={message}')
        break
    elif time1 < time_format:
        print('Enter correct time')
        break
    else:
        print('waiting..')

我将消息、联系电话和时间作为用户的输入。每当条件满足时，WhatsApp 就会打开，并显示您之前输入的联系电话和消息。

唯一的问题是，我必须手动点击发送按钮来发送消息。其他一切正常。

有没有办法做到这一点？如果您在不使用 Selenium 的情况下提供解决方案，那就太好了

提前致谢！

这似乎不是很有效，也不是很好地不断检查用户给出的时间是否与当前时间相同。 schedule 模块对此非常有帮助，它确实有助于使您的代码看起来更干净。我将提供 2 个答案，一个带有 schedule 库，一个没有它。

请记住，如果用户输入了一个已经过去的时间，这对程序来说并不重要，它只会在用户提供的时间是当前设备时间的下一次发送消息。例如 如果用户输入 13:10:00 并且当前设备时间是 14:00:00 那么消息将在下一次当前时间是 13:10:00 时发送，即 next天。

import os
import time
import webbrowser
from datetime import datetime
from string import ascii_letters

name = input('Enter the contact number of a person you want to send message in WhatsApp: ')
message = input('Enter the message:\n')
time1 = input('Enter time in {hh:mm:ss} format: ')

# Check if there aren't any ':' in the input time
if ":" not in time1:
    print("Please input a correct time format")
    os._exit(0)
# Check if there are any letters in the input time
elif ascii_letters in time1:
    print("Please input a correct time format")
    os._exit(0)

print(f'Time entered by user: {time1}')

# Check every .9 seconds if the current time is the same as the user input time
while True:
    current_time = datetime.now().strftime("%H:%M:%S")
    print(f'Current time: {current_time}')

    if time1 == current_time:
        webbrowser.open_new_tab(f'https://web.whatsapp.com/send?phone=+91{name}&text={message}')
        break
    else:
        time.sleep(0.9)

使用schedule 库，它可能看起来像这样：

（你可能会这样做）

import os
import time
import schedule
import webbrowser
from string import ascii_letters

def send_whatsapp_msg(name, message):
    webbrowser.open_new_tab(f'https://web.whatsapp.com/send?phone=+91{name}&text={message}')
    return schedule.CancelJob  # do this if you want to send this message only once
    # or just exit the program entirely if you don't want to run any more tasks
    # os._exit(0)


name = input('Enter the contact number of a person you want to send message in WhatsApp: ')
message = input('Enter the message:\n')  # Message to be sent
time1 = input('Enter time in {hh:mm:ss} format: ')  # Time to sent the message

# Check if there aren't any ':' in the input time
if ":" not in time1:
    print("Please input a correct time format")
    os._exit(0)
# Check if there are any letters in the input time
elif ascii_letters in time1:
    print("Please input a correct time format")
    os._exit(0)

print(f'Time entered by user: {time1}')

# Schedule the message to be sent
schedule.every().day.at(time1).do(send_whatsapp_msg, name, message)

# Wait for the tasks to run and check the time every .9 seconds
while True:
    schedule.run_pending()
    time.sleep(0.9)

为了解决按钮点击问题，我想我找到了一个 "hacky" 解决方案，使用 selenium 和 pyautogui。在 Windows 上，您只需安装 WhatsApp 应用程序并扫描 QR 码一次，然后此解决方案可能适合您。

您还必须安装 selenium chrome 网络驱动程序并截取“箭头”按钮以将消息发送到 WhatsApp 应用程序。这里是 janky 解决方案：

import os
import time
import schedule
import pyautogui
from string import ascii_letters
from selenium import webdriver
from selenium.webdriver.commn.keys import Keys


def send_whatsapp_msg(name, message):
    driver = webdriver.Chrome()  # you can user different drivers like 'Firefox()' but you will have to install them first
    # look at https://selenium-python.readthedocs.io/installation.html for more info

    driver.get("https://api.whatsapp.com/send?phone=+91{name}&text={message}")
    time.sleep(10)  # Wait for everything to set up, can be assigned lower values

    # Click on the 'Open WhatsApp' Prompt Button
    # Much easier to do it with pyautogui since I couldn't make it work with Selenium
    # Look at https://pyautogui.readthedocs.io/en/latest/quickstart.html#screenshot-functions for the '.locateCenterOnScreen' function
    coords = pyautogui.locateCenterOnScreen("open_whatsapp.png")
    pyautogui.click(coords[0], coords[1])  # read the docs on what '.locateCenterOnScreen' returns

    time.sleep(15)  # Wait for the WhatsApp dektop app to load up

    coords = pyautogui.locateCenterOnScreen("click_send.png")  # coordinates for the 'send' button
    pyautogui.click(coords[0], coords[1])
    # Your message has been sent!

    return schedule.CancelJob  # do this if you want to send this message only once
    # or just exit the program entirely if you don't want to run any more tasks
    # os._exit(0)


name = input('Enter the contact number of a person you want to send message in WhatsApp: ')
message = input('Enter the message:\n')  # Message to be sent
time1 = input('Enter time in {hh:mm:ss} format: ')  # Time to sent the message

# Check if there aren't any ':' in the input time
if ":" not in time1:
    print("Please input a correct time format")
    os._exit(0)
# Check if there are any letters in the input time
elif ascii_letters in time1:
    print("Please input a correct time format")
    os._exit(0)

print(f'Time entered by user: {time1}')

# Schedule the message to be sent
schedule.every().day.at(time1).do(send_whatsapp_msg, name, message)

# Wait for the tasks to run and check the time every .9 seconds
while True:
    schedule.run_pending()
    time.sleep(0.9)

click_send.png 看起来像这样：

而open_whatsapp.png 看起来像这样：

open_whatsapp.png 是网站提示您的“打开 WhatsApp” 按钮的屏幕截图，但我的语言不同，所以我不得不将其编辑掉。

我也不知道pyautogui 的可靠性如何，但每次我尝试运行它时它都能正常工作，所以我猜它有点工作。
