我在使用 python Bot 时遇到了一些问题，例如无法识别驱动程序

Question

请有人告诉我为什么这段代码会出现这个错误？我正在尝试运行一个whatsapp bot。但是，当我运行我的代码时，我收到以下错误。

错误：

Traceback (most recent call last):
  File "C:\Users\lwyzb\OneDrive\Documentos\Bot whatsapp\wppBot.py", line 32, in <module>
    bot.MsgSend()
  File "C:\Users\lwyzb\OneDrive\Documentos\Bot whatsapp\wppBot.py", line 16, in MsgSend
    self.driver.get('https://web.whatsapp.com/')
AttributeError: 'WhatsappBot' object has no attribute 'driver'

代码：

from selenium import webdriver
import time

class WhatsappBot:
    def _init_(self):
        self.msg = "Bom dia famiiiilia"
        self.groups = ["Churras ??/?? ????????????", "PARÇAS (Nova formação)", "Parças incorporated"]
        options = webdriver.ChromeOptions()
        options.add_argument('lang=pt-br')
        self.driver = webdriver.Chrome(executable_path=r'./chromedriver.exe')

    def MsgSend(self):
          # <span dir="auto" title="PARÇAS (Nova formação)" class="_3ko75 _5h6Y_ _3Whw5">PARÇAS (Nova formação)</span>
          # <div tabindex="-1" class="_3uMse">
          # <span data-testid="send" data-icon="send" class="">
          self.driver.get('https://web.whatsapp.com/')
          time.sleep(30)
          for group in self.groups:
              group = self.driver.find_element_by_xpath(f"//span[@title='{group}']")
              time.sleep(3)
              group.click()
              chatBox = self.driver.find_element_by_class_name('_3uMse')
              time.sleep(3)
              chatBox.click()
              chatBox.send_keys(self.msg)
              send = self.driver.find_element_by_xpath("//span[@data-icon='send']")
              time.sleep(3)
              send.click()
              time.sleep(5)

bot = WhatsappBot()
bot.MsgSend()         

Answer 1

你的 init 函数命名不正确 - 它应该是 __init__，而不是 _init_：

from selenium import webdriver
import time

class WhatsappBot:
    def __init__(self):
        self.msg = "Bom dia famiiiilia"
        self.groups = ["Churras ??/?? ???", "PARÇAS (Nova formação)", "Parças incorporated"]
        options = webdriver.ChromeOptions()
        options.add_argument('lang=pt-br')
        self.driver = webdriver.Chrome(executable_path=r'./chromedriver.exe')

    def MsgSend(self):
          # <span dir="auto" title="PARÇAS (Nova formação)" class="_3ko75 _5h6Y_ _3Whw5">PARÇAS (Nova formação)</span>
          # <div tabindex="-1" class="_3uMse">
          # <span data-testid="send" data-icon="send" class="">
          self.driver.get('https://web.whatsapp.com/')
          time.sleep(30)
          for group in self.groups:
              group = self.driver.find_element_by_xpath(f"//span[@title='{group}']")
              time.sleep(3)
              group.click()
              chatBox = self.driver.find_element_by_class_name('_3uMse')
              time.sleep(3)
              chatBox.click()
              chatBox.send_keys(self.msg)
              send = self.driver.find_element_by_xpath("//span[@data-icon='send']")
              time.sleep(3)
              send.click()
              time.sleep(5)

bot = WhatsappBot()
bot.MsgSend()       

Python 只查找 __init__ 函数 - 由于您不小心忘记了这两个下划线，Python 没有意识到它应该是初始化程序，因此它没有运行它。

Answer 2

一切正常，但是大声笑你缺少__init__ 的两个下划线，所以类没有正确初始化：

from selenium import webdriver
import time

class WhatsappBot:
    def __init__(self):
        self.msg = "Bom dia famiiiilia"
        self.groups = ["Churras ??/?? ???", "PARÇAS (Nova formação)", "Parças incorporated"]
        options = webdriver.ChromeOptions()
        options.add_argument('lang=pt-br')
        self.driver = webdriver.Chrome(executable_path=r'./chromedriver.exe')

    def MsgSend(self):
          # <span dir="auto" title="PARÇAS (Nova formação)" class="_3ko75 _5h6Y_ _3Whw5">PARÇAS (Nova formação)</span>
          # <div tabindex="-1" class="_3uMse">
          # <span data-testid="send" data-icon="send" class="">
          self.driver.get('https://web.whatsapp.com/')
          time.sleep(30)
          for group in self.groups:
              group = self.driver.find_element_by_xpath(f"//span[@title='{group}']")
              time.sleep(3)
              group.click()
              chatBox = self.driver.find_element_by_class_name('_3uMse')
              time.sleep(3)
              chatBox.click()
              chatBox.send_keys(self.msg)
              send = self.driver.find_element_by_xpath("//span[@data-icon='send']")
              time.sleep(3)
              send.click()
              time.sleep(5)

bot = WhatsappBot()
bot.MsgSend()
