python爬虫-使用selenium自动登录微博

环境准备：anaconda、pycharm编辑器、chromedriver(记得下载)
首先查看本地anaconda的python环境和selenium版本号(不同版本的api接口可能不同)

conda list python

输出

我的python版本是3.11.3，所以我默认下载的selenium版本号是 selenium 4.11.2

自动登录的python脚本代码如下：

import time
from selenium import webdriver
from selenium.webdriver.common.by import Bydef csv_writer(item):with open("weibo.csv", "a", newline='') as csvfile:writer = csv.writer(csvfile)writer.writerow(item)def login():driver.get("https://weibo.com/login.php")time.sleep(5)# 旧版本的接口是driver.find_element_by_id,自行更改username = driver.find_element(by=By.ID, value="loginname")username.send_keys('此处换成你自己的用户名')time.sleep(3)password = driver.find_element(by=By.NAME, value="password")password.send_keys('此处换成你自己的密码')time.sleep(3)submit = driver.find_element(by=By.XPATH, value='//*[@class="W_btn_a btn_32px"]')submit.click()time.sleep(3600)if __name__ == "__main__":driver = webdriver.Chrome()login()time.sleep(3600)

最后运行这个脚本文件即可自动登录微博
