问题
I am trying to send whatsapp message to contacts using Python but getting an error:
InvalidSelectorException: Message: invalid selector: Unable to locate an element with the xpath expression //span[@title = "Me Postpaid"]"}
(Session info: chrome=73.0.3683.103)
(Driver info: chromedriver=73.0.3683.68 (47787ec04b6e38e22703e856e101e840b65afe72),platform=Windows NT 6.1.7601 SP1 x86_64)
I have used selenium for this and the code is mentioned below:
from selenium import webdriver
driver = webdriver.Chrome('C:/Users/....../chromedriver_win32/chromedriver.exe')
driver.get('https://web.whatsapp.com/')
name = input('Enter the name of person or group you want to message: ')
msg = input('Enter your Message: ')
count = int(input('Enter how many times you want to send this message: '))
input('Enter any key after scanning QR code')
user = driver.find_element_by_xpath('//span[@title = " {}"]'.format(name)).click()
#user.click()
msg_box = driver.find_element_by_class_name('_1Plpp')
for i in range(count):
msg_box.send_keys(msg)
button = driver.find_element_by_class_name('_35EW6')
button.click()
How can I make this work ???
回答1:
click() doesn't returns anything. So you need to remove the assignment and format the line of code properly replacing:
user = driver.find_element_by_xpath('//span[@title = " {}"]'.format(name)).click()
with:
driver.find_element_by_xpath('//span[@title= "{}"]'.format(name)).click()
