在LinkedIn上使用Selenium和Python-Java 学习之路

-1

我正在使用python和selenium构建脚本，点击网络上的“消息按钮”发送默认消息 .

Linkedin使用动态字段（ember），因此无法通过id查找元素 . 到目前为止，我尝试过：

driver.find_elements_by_class_name("...").click()
driver.find_element_by_tag_name("button").click()
driver.find_element_by_css_selector("...").click()
driver.find_element_by_xpath(//...)

到目前为止这是我的代码：

def TextBot(browser):
time.sleep(3)
browser.get('https://www.linkedin.com/mynetwork/invite-connect/connections/')
time.sleep(3)
xpath = '//button[contains(@aria-label,"Send message to")]'
time.sleep(3)
buttons = driver.find_element_by_xpath(xpath)
for btn in buttons:
    print("Can %s" % btn.get_attribute("aria-label"))  

def Main():
#Parse enail and password to the script
parser = argparse.ArgumentParser()
parser.add_argument('email', help='linkedin email')
parser.add_argument('password', help='linkedin password')
args = parser.parse_args()

#browse to the login page
browser = webdriver.Firefox()
browser.get('https://linkedin.com/uas/login')

#Parse the two argument in the login form
emailElement = browser.find_element_by_id('session_key-login')
emailElement.send_keys(args.email)
passElement = browser.find_element_by_id('session_password-login')
passElement.send_keys(args.password)
passElement.submit()

#Initialise ViewBot function
os.system('clear') #cls rather than clear on windows
print ("[+] Success! Logged In, Bot Starting")
#ViewBot(browser)
TextBot(browser)
browser.close()

而我的错误：

文件“LinkedInBot.py”，第88行，TextBot按钮= driver.find_element_by_xpath（xpath）文件“/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/selenium/webdriver/ remote / webdriver.py“，第393行，在find_element_by_xpath中返回self.find_element（by = By.XPATH，value = xpath）File”/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site- packages / selenium / webdriver / remote / webdriver.py“，第966行，在find_element'value'：value}）['value']文件”/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7 /site-packages/selenium/webdriver/remote/webdriver.py“，第320行，执行self.error_handler.check_response（响应）文件”/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/ site-packages / selenium / webdriver / remote / errorhandler.py“，第242行，在check_response中引发exception_class（消息，屏幕，堆栈跟踪）selenium.common.exceptions.NoSuchElementException：消息：无法找到element：// button [contains（ @ aria-label，“发给我ssage to“）]

还有什么我没想到的吗？

顺便感谢到目前为止的答案 . 我很接近，但我仍然认为还有其他形式的加密可以绕过

Linkedin中的“消息按钮”如下所示：

<button class="message-anywhere-button mn-connection-card__message-btn button-secondary-medium" aria-label="Send message to John Smith" data-ember-action="" data-ember-action-5128="5128">
  <span aria-hidden="true">Message</span>
  <span class="visually-hidden">
    Send a message to John Smith
  </span>
</button>

所以对于定位器你有几个选项，让我们解决最原始的问题：在 aria-label 中查找 Send message to 文本：

xpath = '//button[contains(@aria-label,"Send message to")]'

该定位器将找到所有按钮 . 但是，根据您调用的函数，您可能最终只选择第一个元素或所有元素 . 让我们说目标是收集所有按钮：

xpath = '//button[contains(@aria-label,"Send message to")]'
all_message_buttons = driver.find_elements(By.XPATH, xpath)
for message_button in all_message_buttons:
    print("Can %s" % message_button.get_attribute("aria-label")) 
    # prints Can Send Message to John Smith
    # and any other names available on page

最后，在选择按钮之前，您需要确保已加载页面并确实显示了按钮 . 有很多方法可以做到这一点，但我通常只需要等待它们来替换我需要的元素：

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
# ...
xpath = '//button[contains(@aria-label,"Send message to")]'
wait = WebDriverWait(browser, 10) # wait for up to 10 sec
all_message_buttons = wait.until(EC.presence_of_element_located((By.XPATH, xpath)))
for message_button in all_message_buttons:
    print("Can %s" % message_button.get_attribute("aria-label")) 
    # prints Can Send Message to John Smith
    # and any other names available on page

下面的代码向下滚动，直到所有联系人都已加载 .
然后获取所有消息按钮，单击，发送和关闭消息窗口 .

from selenium.webdriver.support import expected_conditions as EC
import re

#...

wait = WebDriverWait(driver, 20)
connectionsHeader = wait.until(EC.visibility_of_element_located((By.CSS_SELECTOR, ".mn-connections__header h2"))).text
totalConnections = int(re.findall(r"\d+", connectionsHeader))
while len(driver.find_elements_by_css_selector(".mn-connections li")) < totalConnections-1:
    driver.execute_script("window.scrollTo(0, 100);")

messageButtons = driver.find_elements_by_css_selector(".mn-connections li button.mn-connection-card__message-btn")

for button in messageButtons:
    button.click()
    wait.until(EC.visibility_of_element_located((By.CSS_SELECTOR, ".msg-form__contenteditable"))).click()
    driver.find_elements_by_css_selector(".msg-form__contenteditable").send_keys('message')
    driver.find_elements_by_css_selector(".js-msg-close").click()
    wait.until(EC.invisibility_of_element_located((By.CSS_SELECTOR, ".js-msg-close")))

不是：代码可能包含拼写错误或小错误 . 随意改进它 .
