使用selenium实现web自动化（三）-----输入用户名密码登录

1、实现自动化登录某个页面，需要输入用户名和密码认证，导入模块和库

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.wait import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
from selenium.webdriver.chrome.options import Options
import re
import subprocess
import time

2、设置Chrome浏览器跳过安全检查

chrome_options = Options()
chrome_options.add_argument('--ignore-certificate-errors') 
chrome_options.add_argument('--ignore-ssl-errors')

3、设置Chrome浏览器禁止证书检查

capabilities = DesiredCapabilities.CHROME.copy()
capabilities['acceptInsecureCerts'] = True

4、使用Chrome WebDriver实例化WebDriver对象，并传入Chrome选项和DesiredCapabilities，启动Chrome浏览器并打开登录页面

driver = webdriver.Chrome(options=chrome_options, desired_capabilities=capabilities)
# 启动Chrome浏览器并打开登录页面
driver.get("https://www.baidu.com/")   #输入需要登录的地址

5、找到用户名和密码输入框并输入用户名和密码，其中"user_name"和"password"分别为登录页面用户名和密码输入框对应的id或name，该值通过开发者页面获取（按F12进入）。"user1"和"123456"分别为自定义的用户名和密码。

username_input = WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.ID, "user_name")))
username_input.send_keys("user1")
time.sleep(1)
password_input = WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.ID, "password")))
password_input.send_keys("123456")
time.sleep(1)

6、找到登录按钮并点击

login_button = WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.ID, "loginbtn")))
login_button.click()
time.sleep(3)

 7、好了，附上完整源代码

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.wait import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
from selenium.webdriver.chrome.options import Options
import re
import subprocess
import time
# 设置Chrome浏览器跳过安全检查
chrome_options = Options()
chrome_options.add_argument('--ignore-certificate-errors') 
chrome_options.add_argument('--ignore-ssl-errors')
# 设置Chrome浏览器禁止证书检查
capabilities = DesiredCapabilities.CHROME.copy()
capabilities['acceptInsecureCerts'] = True
driver = webdriver.Chrome(options=chrome_options, desired_capabilities=capabilities)
# 启动Chrome浏览器并打开登录页面
driver.get("https://www.baidu.com/")
time.sleep(3)
# 找到用户名和密码输入框并输入用户名和密码
username_input = WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.ID, "user_name")))
username_input.send_keys("user1")
time.sleep(1)
password_input = WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.ID, "password")))
password_input.send_keys("123456")
time.sleep(1)
# 找到登录按钮并点击
login_button = WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.ID, "loginbtn")))
login_button.click()
time.sleep(3)
