如何使用 python 读取联系人的 whatsapp 消息？

Question

我正在构建一个在指定时间登录缩放的机器人，并且链接是从 whatsapp 获取的。 所以我想知道是否可以直接从 whatsapp 中检索这些链接，而不必将其复制粘贴到 python 中。 谷歌充满了发送消息的指南，但有没有办法阅读和检索这些消息然后操纵它？

Answer 1

您最多可以尝试使用Selenium WebDriver阅读带有 Python 的 WhatsApp 消息，因为我强烈怀疑您是否可以访问 WhatsApp API。

Selenium is basically an automation tool that lets you automate tasks in your browser so, perhaps, you could write a Python script using Selenium that automatically opens WhatsApp and parses HTML information regarding your WhatsApp web client.

首先，我们提到了 Selenium，但我们只会使用它来自动打开和关闭 WhatsApp，现在我们必须找到一种方法来读取 WhatsApp 客户端内部的内容，这就是 Web Scraping 的魔力所在。

Web 抓取是从网站提取数据的过程，在这种情况下，数据由您需要自动获取的 Zoom 链接表示，而 web 站点是您的 WhatsApp 客户端。 要执行此过程，您需要一种从网站中提取（解析）信息的方法，为此我建议您使用Beautiful Soup ，但我建议您至少需要了解 HTML 的工作原理。

抱歉，如果这可能无法完全回答您的问题，但这是我对这个特定主题的所有知识。

您可以使用 Python 中的https://selenium-python.readthedocs.io/在浏览器上打开 WhatsApp。

Selenium is basically an automation tool that lets you automate tasks in your browser so, perhaps, you could write a Python script using Selenium that automatically opens WhatsApp and parses HTML information regarding your WhatsApp web client.

我从“ https://towardsdatascience.com/complete-beginners-guide-to-processing-whatsapp-data-with-python-781c156b5f0b ”这个网站学习和使用代码。 Go 通过上述链接上的详细信息。

您必须从此链接安装外部 python 库“ whatsapp-web ”---“ https://pypi.org/project/whatsapp-web/ ”。 只需通过“python -m pip install whatsapp-web”输入命令提示符/windows 终端。

它会显示结果---

python -m pip 安装whatsapp-web

收集whatsapp-web

下载 whatsapp_web-0.0.1-py3-none-any.whl (21 kB)

安装收集的包：whatsapp-web

成功安装whatsapp-web-0.0.1

Answer 3

更新：

Please change the xpath's class name of each section from the current time class name of WhatsApp web by using inspect element section in WhatsApp web to use the following code. 因为 WhatsApp 已更改其元素的 class 名称。

我已经尝试过使用 python 创建一个 WhatsApp 机器人。 但是由于我也是初学者，所以仍然有很多错误。

基于我的研究的步骤：

1. 使用 selenium webdriver 打开浏览器
2. 使用二维码登录 WhatsApp
3. 如果您知道将从哪个号码收到会议链接，请使用此步骤，否则请在此过程之后检查以下过程提及。

• 找到并打开您将收到缩放会议链接的聊天室。

从已知聊天室获取消息以执行操作

#user_name = "Name of meeting link Sender as in your contact list"
Example :
user_name = "Anurag Kushwaha"
#In above variable at place of `Anurag Kushwaha` pass Name or number of Your Teacher
# who going to sent you zoom meeting link same as you have in your contact list.
user = webdriver.find_element_by_xpath('//span[@title="{}"]'.format(user_name))
user.click()
# For getting message to perform action 
message = webdriver.find_elements_by_xpath("//span[@class='_3-8er selectable-text copyable-text']") 
# In the above line Change the xpath's class name from the current time class name by inspecting span element
# which containing received text message of any chat room.

for i in message:
    try:
        if "zoom.us" in str(i.text):
            # Here you can use you code to preform action according to your need
            print("Perform Your Action")
     except:
        pass

4. 如果您不知道您将通过哪个号码收到链接。
5. 然后，您可以获得任何未读联系人块的 div class 并打开所有包含该未读 div class 的聊天室列表。
6. 然后检查打开聊天的所有未读消息，并从 div class 中获取消息。

当您不知道您将从谁那里收到缩放会议链接时。

# For getting unread chats you can use
unread_chats = webdriver.find_elements_by_xpath("// span[@class='_38M1B']")
# In the above line Change the xpath's class name from the current time class name by inspecting span element
# which containing the number of unread message showing the contact card inside a green circle before opening the chat room.

# Open each chat using loop and read message.
for chat in unread_chats:
    chat.click()

    # For getting message to perform action
    message = webdriver.find_elements_by_xpath("//span[@class='_3-8er selectable-text copyable-text']")
    # In the above line Change the xpath's class name from the current time class name by inspecting span element
    # which containing received text message of any chat room.
    for i in messge:
        try:
            if "zoom.us" in str(i.text):
                # Here you can use you code to preform action according to your need
                print("Perform Your Action")
         except:
             pass

注意：在上面的代码中，“webdriver”是您打开 web.whatsapp.com 的驱动程序

例子：

from selenium import webdriver
webdriver = webdriver.Chrome("ChromePath/chromedriver.exe")
webdriver.get("https://web.whatsapp.com")
# This wendriver variable is used in above code.
# If you have used any other name then please rename in my code or you can assign your variable in that code variable name as following line.
webdriver = your_webdriver_variable

完整的代码参考示例：

from selenium import webdriver
import time
webdriver = webdriver.Chrome("ChromePath/chromedriver.exe")
webdriver.get("https://web.whatsapp.com")
time.sleep(25) # For scan the qr code
# Plese make sure that you have done the qr code scan successful.
confirm = int(input("Press 1 to proceed if sucessfully login or press 0 for retry : "))
if confirm == 1:
   print("Continuing...")
elif confirm == 0:
   webdriver.close()
   exit()
else:
   print("Sorry Please Try again")
   webdriver.close()
   exit()
while True:
    unread_chats = webdriver.find_elements_by_xpath("// span[@class='_38M1B']")
    # In the above line Change the xpath's class name from the current time class name by inspecting span element
    # which containing the number of unread message showing the contact card inside a green circle before opening the chat room.
    
    # Open each chat using loop and read message.
    for chat in unread_chats:
        chat.click()
        time.sleep(2)
        # For getting message to perform action
        message = webdriver.find_elements_by_xpath("//span[@class='_3-8er selectable-text copyable-text']")
        # In the above line Change the xpath's class name from the current time class name by inspecting span element
        # which containing received text message of any chat room.
        for i in messge:
            try:
                if "zoom.us" in str(i.text):
                    # Here you can use you code to preform action according to your need
                    print("Perform Your Action")
             except:
                pass

Answer 4

您可以从 whatsapp web 读取所有 cookies 并将它们添加到标头并使用请求模块，或者您也可以使用 selenium 。

Answer 5

试试这个有点麻烦，但它可能会奏效

import pyautogui
import pyperclip
import webbrowser

grouporcontact = pyautogui.locateOnScreen("#group/contact", confidence=.6) # Take a snip of the group or contact name/profile photo
link = pyperclip.paste()

def searchforgroup():
     global link
     time.sleep(5)
     webbrowser.open("https://web.whatsapp.com")
     time.sleep(30)#for you to scan the qr code if u have done it then u can edit it to like 10 or anything
     grouporcontact = pyautogui.locateOnScreen("#group/contact", confidence=.6)
     x = grouporcontact[0]
     y = grouporcontact[1]
     if grouporcontact == None:
        #Do any other option in my case i just gave it my usual link as
        link = "mymeetlink"
     else:
         pyautogui.moveTo(x,y, duration=1)
         pyautogui.click() 
# end of searching group
def findlink():
    global link
    meetlink = pyautogui.locateOnScreen("#", confidence=.6)#just take another snap of a meet link without the code after the "/"
    f = meetlink[0]
    v = meetlink[1]
    if meetlink == None:
        #Do any other option in my case i just gave it my usual link as
        link = "mymeetlink"
   else:
       pyautogui.moveTo(f,v, duration=.6)
       pyautogui.rightClick()
       pyautogui.moveRel(0,0, duration=2) # You Have to play with this it basically is considered by your screen size so just edit that and edit it till it reaches the "Copy Link Address"
       pyautogui.click()
       link = pyperclip.paste()
       webbrowser.open(link) # to test it out

所以现在你必须安装 pyautogui、pyperclip 并按照代码片段中的注释进行操作，一切都应该正常工作:)
